Tuesday, February 14th, 2012GeoExchange Concept, How will this work for my Muskoka home
Thursday, February 9th, 2012GeoExchange Concept
How is heat actually transferred between the ground and the building?
As a fluid is circulated through the buried pipe, it attracts heat from the surrounding ground; the further the fluid flows, the more heat it can extract. When the warm fluid returns to the compressor, heat is taken from the fluid and transferred to the heat pump, where it warms air prior to circulation throughout the building. In summer, the compressor transfers building heat into the loop fluid, which then dissipates heat into the ground as it circulates, and returns to the building in a cooled state.
How can a geoexchange system heat both air and water?
The solar heat that is transferred out of the ground can be used either to warm air (for use in a forced air distribution system) or to heat water (for drinking or service applications, or in radiant heating or swimming pools).
How does the geoexchange system extract heat from frozen soil?
The loop is buried below the frost line, and insulation is used to protect any section that may rise above the frost line (e.g.: as the pipe enters the building) to avoid freezing in winter.
Can a geoexchange system be used for anything other than heating and cooling a building?
Twenty percent of the average energy demand in a residential home is for water heating, and most units include a component to heat water for potable or sanitary use. Heat pumps can also be used to dehumidify indoor swimming pool areas, by controlling condensation with a minimum of ventilation and using the recovered heat in the main heating process.
What happens if a geoexchange system tries to extract too much heat from the ground?
When the loop cannot obtain sufficient heat from the ground, most systems include a back-up electric element to provide supplemental heat. If the demand for heat is higher than the combined supply from the outside loop and the electric backup, most systems will shut down. Note: the backup electric system continues to provide heat until the problem is fixed.
What makes a geoexchange system different from conventional heating and cooling systems?
Most space heating and water heating in Canada are provided by combustion of natural gas, oil or propane, or by electric resistance, while most cooling is provided by electric air conditioning. A geoexchange system does not use combustion to make heat; it simply transfers solar heat from the ground at very high efficiency. This lack of combustion makes a geoexchange system a best choice from an environmental and safety standpoint.
Do geoexchange systems have outdoor units?
The ground loop is buried in the soil and enters the building through an underground penetration. There are no visual components outdoors.
Does a geoexchange system require separate ground loops for heating and cooling?
In Canada, a geoexchange unit is used more for heating than for cooling, and a reversing valve can be switched between seasons to reverse the flow of the loop fluid and the operation of the heat pump. The system design may be over-sized for the second application, but that means the unit cycles less frequently.
Can a geoexchange system work with a diesel generator?
The generator must be of sufficient capacity and have a constant voltage, to meet the electrical demands of the heat pump operation, including circulating pump for the loop and distribution pump for the hot air.
What is the difference between a geoexchange and an air-source heat pump?
An air-source system is a similar concept to a geoexchange system, but it extracts heat from outside air instead of from the ground. Winter air does not contain much latent heat, and the efficiency of an air-source unit drops significantly when outside temperatures drop below 0 o Celsius. The compressor in an air-source unit is located in the outdoor compartment, where it is noisy and exposed to weather elements. By comparison, a geoexchange system is more efficient due to higher ground temperatures in winter, and the absence of any outdoor equipment makes a geoexchange system quieter, more aesthetically pleasing and longer lasting.
Can geoexchange systems be used in commercial or industrial buildings, or in apartment or school?
Absolutely. Research conducted for NRCan indicates that these applications are very cost-effective and offer high reductions of greenhouse gas emissions. Often, these applications offer a more balanced load profile than a residential home and, therefore, are less expensive for the heating or cooling supplied. More than half the geoexchange systems installed in Canada are used in these applications.
Can heating and cooling occur simultaneously in the same building?
Yes. Each heat pump unit can perform only one function at a time, but a larger building (with more than one unit) can provide heating to one spot and cooling to another. This is a common application in schools and other institutional facilities, which have a diverse load. The practice also increases the efficiency of the overall system because the heat removed from room A can be transferred to room B, reducing the need for the ground loop to provide both heating and cooling (and thereby reducing the total installed cost).
Can a geoexchange system provide heat recovery ventilation (HVR)?
Some units integrate a HRV unit that can provide fresh air and enhance building comfort, and offer enhanced defrosting without creating negative pressure inside the building.
Is the compressor in a geoexchange unit the same compressor as in a refrigerator?
In principle, yes. A refrigerator is designed to cool food by extracting heat from the package and transferring the warm air into the kitchen. A geoexchange system can be reversed to provide cooling or heating, depending on the season. There are numerous compressors on the market, all of which use the same general principles, although the specific models used in a geoexchange system are different from the kitchen appliance.
Is there a national or local standard for the design and installation of a geoexchange system?
Design and installation are covered under national CSA standards C447 (commercial) and C445 (residential). As of March 2002, both applications are covered under the CSA C448 standard. CGC is not aware of any mandatory provincial regulations pertaining to geoexchange systems, although some municipalities or regulatory agencies may have guidelines or rules, which have an impact on the design or installation of geoexchange systems
Tips on choosing the right Muskoka heating cooling company
Wednesday, February 8th, 2012Tips For Selecting
The Right Dealer
-
Check to see if the dealer possess all of the appropriate licensing for installing HVAC equipment in your state and local area.
-
Ask how long they have been in business; if they offer 24/7 service, financing, or accept credit cards.
-
Ask the steps they will take to install your equipment. A proper installation will follow the 3-part process on previous page.
-
A dealer coming into your home should do more than just inspect your existing system. Follow them around to see if they are checking air flow, inspecting the duct system, making note of the windows and the direction your home faces, etc.
-
Be wary of anyone who shoots you an estimate on the back of a business card after being in your home for a few minutes, or even over the phone.
-
A knowledgeable dealer that has your best interest in mind will ask about your experiences in the home; how long you have lived there, how long you plan to stay, if you have pets, allergies, smokers, hot and cold spots, noise, etc.
-
A dealer with the tools to address these problems will offer viable solutions such as air cleaners, zoning equipment, programmable thermostats, humidifiers, variable speed and two-stage technology, etc. If they do not offer these solutions, they may not be the right dealer for you!
-
It takes more time to complete an installation when done correctly. Expect to pay more for comprehensive service, but much less in the long run for your system’s performance and maintenance.
-
Typically, manufacturer warranties cover the replacement of faulty components for a limited time. Failure due to poor installation is typically not warranted by manufacturers. Select a dealer who will do a good job the first time and be around to assist you as needed.

Muskoka Geothermal groundsource or watersource Performance Questions
Friday, February 3rd, 2012Performance Questions
How efficient is a geoexchange system?
The performance of the heat pump unit is rated by its ‘Coefficient of Performance’, which calculates how much energy is required to transfer heat into a building. Units are tested under the CSA C446, ARI 320, ARI 325 or ISO 13126 standards. In Canada, units cannot be sold if they rate below 2.8 CoP and many units achieve 3.5 or above. If the CoP is 3.5, a system requires 1 kW of electrical energy to transfer and deliver 3,500 W of space heat; this is equivalent to a combustion furnace with an efficiency of 380 percent.
How long will the loop pipe last?
The pipe is high-density polyethylene. Most suppliers provide a warranty of 25 years or more, and the pipe will usually last longer.
What factors will affect the performance of a geoexchange system?
Common problems for degradation of output in a well-designed system include dirty air filters (fixed by cleaning), air trapped in the ground loop (requiring purging) and declining anti-freeze level (fixed by adding more to the loop). Human error includes mis-setting the thermostat while natural problems include dropping water table or increasing mineral content in the water.
Is a geoexchange system more comfortable than a conventional furnace?
A heat pump moves a large volume of warm air throughout a building, but it is at a lower temperature than a combustion furnace, resulting in an even and steady delivery with no draughts. The lack of combustion and higher air circulation of a geoexchange system results in less indoor air contamination and lower pollution levels, as well as reduced humidity build-up.
What happens when the outdoor temperature becomes very cold?
Although the outdoor ambient temperature can drop significantly and quickly, the temperature of the ground below the frost line remains constant and it is from this level that a geoexchange system extracts heat. In the worst case scenario where the outdoor temperature drops for a prolonged period and there is an extraordinarily high demand for heat, the supplemental heating unit on the geoexchange heat pump will provide the difference in heat.
Does the quality or quantity of water have any bearing on performance?
Water that comes directly from a lake or a well must meet certain levels for temperature and flow rate, and must contain few minerals. The CSA standard requires an official water well log to ensure that the yield is sustainable, and an analysis should be done to determine if the water contains any chemicals or metals that could damage the heat exchanger or other component.
Can a geoexchange system be diagnosed by long distance?
Some manufacturers have incorporated electronic measurements to provide diagnostic capability over the telephone. In some cases, this allows the system to be re-set without a service call.
How safe is a geoexchange system?
A geoexchange system is considered to be one of the safest heating/cooling systems available. No combustible fuels are used, which eliminates any chance of explosion, and it also reduces concerns over indoor air quality (IAQ). There are no outside components that can be tampered with or vandalized.
What are the options for water heating?
A geoexchange system heats domestic water with a demand unit or a de-superheater. The former gives priority to water heating over space heating, while a de-superheater will heat water only after space heating has been accomplished. The difference depends on the lifestyle of the occupants.
How durable is the pipe in the ground loop?
The CSA standard allows only high-density polyethylene pipe, with the three most common diameters being 0.75″, 1.0″ and 1.25″. Sections of pipe are heat fused and many suppliers offer a warranty of 25 years. The resin in this pipe is the same used in the pipe used to transport natural gas. This plastic does not degrade under sunlight and is warranteed not to fail.
Does a geoexchange system come complete with all components?
Most units include all pumps and controls, but it may be the responsibility of the contractor to obtain some individual components. All non-packaged components must be compatible with the heat pump unit, and written documents should demonstrate that the manufacturer allows the components to be used and that their use will not interfere with warranty coverage.
Are geoexchange contractors certified?
A number of manufacturers offer training for their authorized contractors that is specific to that brand but, as of 2002, there is no certification program in Canada. A programme was offered by the Canadian Earth Energy Association (the predecessor of the Earth Energy Society) until 1993. There is a program offered by the International Ground Source Heat Pump Association and the Geothermal Heat Pump Consortium in the United States. There are a number of related certifications (for heat loss analysis, ductwork installation, etc) offered by the Heating, Refrigeration & Air-conditioning Institute of Canada, among others.
Where does water from an open-loop system go?
There are environmental regulations, which govern how the water used in an open-loop system can be returned to the ground. A return well is acceptable, as long as the water is returned to the same aquifer or level of water table. A discharge pit is also acceptable, as long as local regulations and conditions are considered in the design.
Are all GeoExchange pipes straight?
There are two coiled loops on the market, called the Slinkey and the Svec Spiral, which require less trenching and reduce installation costs. The installation of coiled pipe is more demanding than straight pipe, and back-filling must be done properly.
How is the CoP efficiency rating determined?
Units are tested under laboratory conditions, with a set temperature for the entering water. The total heat output and the electricity required to operate the entire system are the two variables used to determine the CoP rating for each unit.
What are the environmental benefits of geoexchange?
Due to the use of solar energy and the high efficiency of the transfer technology (the heat pump), a geoexchange system can greatly reduce emissions of CO2 and other greenhouse gas emission compared with combustion furnaces. The lack of combustion naturally means a chimney is not needed.
Is there a lot of noise from a geoexchange system?
The compressor, pump and blower are all sound-insulated. The CSA standard requires a heat pump to be placed on top of an acoustical air pad to eliminate vibration noise and there must be sound dampeners where the heat pump connects to the ductwork. The system is one of the quietest options on the market.
Can a large number of geoexchange systems create ecological problems?
Each system is designed to ensure sufficient heat from the property in which it operates, and there is no potential to “freeze the globe” or to disturb natural habitats or ecosystems. Systems use renewable energy to heat a building, and benefits to the environment increase with the number of units added to a geoexchange system, when compared with conventional fuel-based heating unit
David Suzuki on Geothermal heating and cooling your Muskoka home or cottage: Geothermal WaterFurnace Heatpumps are the way to go.
Wednesday, February 1st, 2012Geothermal heat pumps are one of the cheapest and most reliable ways to heat
and cool most buildings today.
Geothermal pumps draw energy from the earth, using a series of underground
pipes. In winter, these systems bring the earth’s warmth up into a building, concentrate
it, and distribute it using heat pumps and ventilation systems. In summer, they
work in reverse, extracting heat from inside to be discharged into the cooler earth.
The earth itself supplies the renewable thermal energy, and the systems run with
almost no pollution or greenhouse gas emissions.
Smart Generation shows geothermal pumps can be widely used to provide heating
and cooling for all new residential and commercial buildings in Ontario. By 2010,
Ontario can install 125,000 residential geothermal pumps, saving the equivalent of
7.7 petajoules per year. By 2020, the province can install 341,000 geothermal systems
in new homes, saving the equivalent of 21 petajoules per year (the equivalent of about
750,000 tonnes of coal, or 3.7 million barrels of oil).
Ontario can follow the example set by Manitoba Hydro, which has become a
Canadian leader in geothermal heat pumps. Manitoba Hydro currently offers
homeowners a loan up to $15,000 to install a geothermal heat pump when building
a new home or replacing an old heating system. According to Manitoba Hydro,
installing 1,000 geothermal heat pumps in homes generates $15 million in construction-
related activity.
The City of Winnipeg is developing plans for a 100 per cent geothermal new
subdivision. If built, it would be the largest geothermal housing development in
Canada.
In Ontario, about 8,500 homes and 500 institutional and commercial buildings
are currently using geothermal systems. These systems offset the need for
electricity-hogging air conditioners and heating systems based on electricity
or natural gas.

Economic benefits
The cost to install a geothermal system that can provide 100 per cent of heating and
cooling is about $20,000 for a new 2,000 square foot home in a Toronto subdivision.
The energy savings achieved by installing a geothermal heat pump are considerable.
Annual heating costs are $400, markedly lower compared to $1,000 for electric
furnace or electric baseboards, $1,250 for a gas furnace or $1,600 for a conventional
oil furnace.
Installing 125,000 home geothermal systems could result in 18,750 jobs by 2007.
By 2020, the installation of 341,000 geothermal pumps could create up to
51,150 jobs.
Fast facts
Ontario can use geothermal
energy for 20 per cent of the air
conditioning and water heating
load in all provincial and municipal
buildings by 2010. This level
should rise to 50 per cent by 2020.
Geothermal energy can be widely

Carbon Monoxide: How do I keep it out of my home?
Tuesday, January 31st, 2012Keep Carbon Monoxide Out of Your Home
Carbon monoxide (CO) is a harmful gas that has no colour, smell or taste.
CO forms whenever you burn fuel such as propane, natural gas, gasoline, oil, coal and wood. It is also contained in second-hand smoke. If furnaces, fireplaces, gas stoves or water heaters are improperly installed, or if they malfunction, they can release CO into your home.
What Are the Health Effects?
CO can cause health problems before people even notice that it is present.
When you breathe in CO, it reduces your body’s ability to carry oxygen in the blood.
Even at low levels of exposure, CO can cause headaches and make you feel tired. The health effects at higher levels can be much more serious and can even lead to death.
How do I know if I Have a Problem?
CO can be detected only with a carbon monoxide detector.
What Can I Do?
- Maintenance is the key!
- There is no substitute for good maintenance of fuel-burning appliances because CO detectors may not detect low levels of CO that can, over time, have effects on your health.
- Make sure appliances such as furnaces, fireplaces, gas stoves and water heaters are well maintained and inspected by a professional at least once a year.
- Get a CO detector!
- Put at least one carbon monoxide (CO) detector in your home. A smoke alarm helps protect against fires, but will not warn you of potentially harmful carbon monoxide in your home. It is important that you have a carbon monoxide detector in your home as well as a smoke alarm.
- Install a Canadian Standards Association (CSA) certified CO detector with an audible alarm to warn you of high CO concentrations in your home. The most important place to install a detector is in hallways, outside of sleeping areas. Make sure to follow the manufacturer’s suggestions on how to install and use the detector, and when it needs to be replaced. You can use a marker to remind yourself when it was installed and when it should be replaced.
- Leave it outside!
- Never use a barbecue indoors.
- Don’t use kerosene or oil space heaters or lamps in enclosed areas unless they’re specifically designed for indoor use.
- No idling indoors!
- Don’t let vehicles idle in the garage, even when the garage door is open.
- Never run gas-powered lawnmowers, trimmers, snow blowers or other machines in the garage.
- Keep the door between your house and the garage closed.
INSTALL A HEAT RECOVERY VENTILATOR
What qustions should I be asking about my Muskoka geothermal ground source or water source design and installation?
Monday, January 30th, 2012Installation Questions
How to size a geothermal heatpump for residential building?
Have a qualified CGC and HRAI contractor takes responsibility for the size. Such as www.gravenhurstplumbing.com
The Canadian Standards Association (CSA) C448 standard requires that horizontal loops be buried at least 4 feet below surface. The deeper the depth the better, as thermal stability increases with depth. Many provinces demand the use of trench scaffolding if depths exceed 6 feet, which imposes a cost. Vertical boreholes have no limits on depth, although an average depth is 100-200 feet.
Is there a national / local standard to govern the installation of a geoexchange system?
As of March 2002, both residential and commercial installations are covered under the Canada Standards Association (CSA) C448. We are not aware of any provincial regulations affecting Geoexchange installation, though some municipalities or other regulatory agencies may have guidelines or rules pertaining to the installation of systems. CGC members should be informed and current on all relevant standards and regulations, though as always, the burden of information falls on the consumer. We therefore recommend consumers raise the question with your local installer and local government officials, until you are satisfied that all necessary standards and regulations have been met.
How far apart should trenches and vertical boreholes be spaced?
Trenches are usually spaced 8-10 feet apart, while boreholes are spaced 10-15 feet apart.
Can someone other than the contractor install the ground loop?
Most contractors prefer to retain control over the entire job to ensure compatibility of all sections, but the digging of the horizontal trench (and backfilling) is one area that could reduce costs if done under the guidance and direction of the installing contractor.
Can a homeowner install a geoexchange system?
It is recommended that a qualified and certified contractor be used to design and install the system. If a homeowner wants to save money and has access to a backhoe, the contractor may provide details on where to trench on the property, and when to backfill after the loop is installed.
How deep should the vertical borehole be drilled?
Deeper is generally better, but there can be technical constraints. Most residential boreholes are 75-100 feet, but some can be as deep as 1000 feet depending on soil properties, heating requirements, and other factors.
How deep should the ground loop be installed?
The CSA C448 standard directs that the minimum depth is 4 feet; the former 445 standard required 2 feet. The objective is to install the loop as far below the frost line as possible. Many provinces require safety measures when a trench is more than six feet deep, so most contractors do not exceed that depth in order to reduce costs.
Are there any concerns with joining sections of underground pipe?
The high-density polyethylene pipe is socket fused (basically, melted together with a high temperature tool), which makes the joined plastic section more solid than the original resin. If done by a certified fusion contractor, there is virtually no chance of breakage or separation under normal conditions.
How many pipes should be installed in a trench?
From one to six, depending on design considerations and the thermal characteristics of the soil.
What spacing is required for the ground loop?
Each pipe extracts heat from the nearby soil, so separation should be as wide as possible. The CSA standard demands at least 10 feet between sections of loop, which can be reduced under certain conditions.
Does a geoexchange system use a setback thermostat?
A geoexchange system relies on a constant, low level of temperature for the building, and any sudden increase in heat demand will cause the supplemental backup heating unit to activate. Setback thermostats are not recommended for use with a geoexchange system.
Is it possible to make a mistake when installing the ground loop?
It is unlikely that a certified loop installer would make any mistake since he/she is trained to fuse sections of loop. The CSA standard requires that a system be tested to a pressure above normal operating levels, to determine if there are any leaks or problems which can be corrected immediately.
Is there a concern with poor-quality water in an open-loop system?
In a closed-loop system, the water must be of good quality and meet the specifications of the heat pump manufacturer and the supplier of the anti-freeze solution with which it is mixed. In an open-loop system, some chemicals and minerals in the water may not be compatible with the heat exchanger. An analysis of the water should be performed before purchase to determine which model of exchanger is required. If the water content changes over time, this may have a detrimental impact on the system.
Can a geoexchange system be added to a fossil fuel furnace?
A dual system can be added to an existing furnace to provide a dual-fuel heating system, where the heat pump is the main source of heating and the combustion furnace provides the supplemental heat.
Is a geoexchange system difficult to install?
The ground loop can be difficult to install, depending on rocks, physical obstructions and topography. The interior heat pump is easy to install, and can be located in areas without proper ventilation (there is no combustion, so no need for exhaust). Most units are easy to install, especially when they are replacing another forced-air system. The air distribution may be difficult in a retrofit installation.
Will a geoexchange loop affect a lawn or landscape?
The only impact will be a period of settling for soil that is placed back in the trench. This visual evidence takes one year to settle.
Can a geoexchange system be located in a septic bed to take advantage of the heat?
The CSA standard specifically bans locating a ground loop near septic systems to avoid retarding the microbial action to decompose sewage. Grey water from the building can be used in some situations, if that collection unit is separate from the septic system.
What heat transfer fluids are permitted?
The anti-freeze that is used in a closed-loop system must be approved by provincial authorities and acceptable to the heat pump manufacturer. Methanol and denatured ethanol are the most common fluids used (methanol is not approved for use in Ontario). The fluid must be mixed with water in accordance with instructions, usually on a 4:1 ratio of water-to-chemical.
Can I install a ground heat exchanger myself?
It is not recommended. In addition to thermal fusion of the pipe, drilling and trenching are procedures best handled by licensed professionals. Non-professional installations may result in less than optimum performance, which could cancel out anticipated savings. Also, warranties are usually void if a non-authorized dealer installs the system.
No. Systems are installed away from trees to avoid damage to root systems when digging the trench.
How long does an installation take?
Depending on soil conditions and the length and depth of pipe, a typical residential system can be installed in two days. Commercial systems depend greatly on geography and system size for accurate estimation.
What laws apply to open-loop installations?
The CSA C448 standard contains a number of requirements to ensure that an open-loop unit does not abuse the increasingly valuable water resource.
Does the capacity of electrical service need to be increased with the addition of a heat pump?
A contractor can advise if an upgrade is required to accommodate the additional electricity required.
Why every home should have a Heat Recovery Ventilator
Thursday, January 26th, 2012Feds look into Canada’s killer homes
Every year, 2,000 die from radon exposure. Is it in your home?
Your life savings are vanishing, your job is in jeopardy, and the repo man has already visited some of your friends and relatives. Now here’s the really bad news: your beloved home—the one you’re desperately trying to save from foreclosure—may actually be killing you (and not because of the mortgage payments).
The culprit? Radon: a tasteless, odourless, invisible gas that lurks in cellars and crawl spaces and is the second-leading cause of lung cancer, next to smoking. Every year, up to 2,000 Canadians die a premature death because their homes—unbeknownst to them —are loaded with tiny radioactive particles.
This nasty little gas is hardly new (scientists have been studying its fatal side-effects for more than a century), but the federal government is suddenly anxious to find out which neighbourhoods are most at risk. Over the next two years, Health Canada plans to spend almost $1 million testing 18,000 randomly chosen homes, with the end result being an online “radon potential map” that pinpoints possible danger zones. “Radon is the largest source of radiation exposure for most Canadians,” says Jack Cornett, a ministry spokesman. “But we are concerned that there is a real lack of awareness about it.”
Here’s what Health Canada wants you to know: first, don’t panic. Radon is a naturally occurring gas released by uranium decay in the soil, and the experts believe that only 2.5 per cent of all homes contain “unsafe” levels (more than 200 becquerels per cubic metre). Second, if you’re still nervous, conduct your own test. Do-it-yourself radon kits cost as little as $50 at the local hardware store. Third, seal all the cracks in your basement floor. Radon loves to seep through those crevices.
Oh, and don’t smoke cigarettes. Apparently that causes lung cancer, too. MOST IMPORTANT: INSTALL A HRV!! SEE:http://www.lifebreath.com/en/consumer/products/residential/hrv/
What is a hybrid system and how can it help heat my Muskoka home?
Wednesday, January 25th, 2012
Most consumers are familiar with the term “hybrid” in reference to cars that combine electric and gas fuel for better performance. Long before dual-fuel cars were on the market, a consumer could get a dual-fuel heating and cooling system. A central hybrid comfort system uses gas and electric heat to reduce heating expenses in the winter while also keeping your home comfortable. It is one of the most economical type of system that does not compromise comfort.
