Don't think you will see natural gas phased out in Ontario . If the government of Ontario stops screwing up our electricity system,then geothermal is a great idea, and really pays off. Being at the mercy of an incompetent bureaucracy is not a good thing. If the furnace is old and needs to be replace maybe is a good time to do the change. This type of approach will encourage businesses to invest in building the carbon friendly infrastructure needed to achieve the carbon reduction targets our government is calling for.
Specialized technical knowledge and equipment is needed to properly install the piping, so a GHP system installation is not a do-it-yourself project. To find a qualified installer, contact your local utility company, theInternational Ground Source Heat Pump Association, or theGeothermal Exchange Organizationfor their listings of qualified installers in your area. Ask for references from owners of systems that are several years old, and check them. There are also special financing andincentivesavailable to help offset the cost of adding a GHP to your home. These provisions are available fromfederal, state, and local governments; power providers; and banks or mortgage companies that offer energy-efficient mortgage loans for energy-saving home improvements. Be sure the system you're interested in qualifies for available incentives before you make your final purchase.
Everything You Need to Know About Geothermal Heat Pumps
Geothermal heat pumps last significantly longer than conventional equipment. In contrast, conventional furnaces generally last anywhere between 15 and 20 years, and central air conditioners last 10 to 15 years. Geothermal energy isn’t more used today mostly because of three reasons. First, the high costs it has compared to other energy sources. And third, because of the risk of earthquakes its installation brings. A permanent closed loop heat exchanger or well system will be installed on your property .
I won't comment on the types of systems you list in the article because they are not the type I am entertaining. I am looking at land in Tennessee where the ground temperature is 19-20C, this eliminates the need for a heat pump and can run exclusively on either forced liquid or, as I prefer, a forced air system. Rather than worrying about fluid leaks and pressure losses, a simple forced air system would be DESIGNED with holes because it's an open loop.
Vertical System
A horizontal ground loop geothermal requires a larger yard than a vertical ground loop system. The vertical ground loop system only requires a 3 ft area, and then the ability to connect the system back to the indoor unit. This is a perfect option for either rural or urban areas. In order to maintain efficiency, geothermal heat pumps are also scaled to provide only the necessary amount of heat for the home. In the throes of the coldest day of the year, the heat pump may run continuously to meet the supply, but this is normal and does not overstress the system. If you’re lucky enough to have a pond a half-acre or larger on your property, your home may be a candidate for a pond loop system.
This will be determined upon a site visit by Ultra Geothermal. The system tonnage needed to accommodate the house can be accurately sized using the square footage of the house and insulation R-values. If the house is very large, several systems are installed that work independently for different zones of the house in both radiant and air applications.
Heat pump buying guide: review of the top 10 heat pumps
According to Bob Donley, customer support manager at GeoSystems LLC in Minnesota, interest in geothermal HVAC is really on the rise. The system may require ductwork modifications along with extensive excavation. In a new home, installation costs would be on the lower end. Even so, a geothermal system will cost about 40 percent more than a traditional HVAC system.
Convenience and performance upgrades available on standard heat pumps will be available for your new geothermal heating and cooling systems. Take your choice of premium air filtration, web-enabled controls and touch-screen thermostats if you like. Plus, you can have domestic hot water and pool heating options, as well as radiant floors.
It depends on how big your house is, how airtight it is and how well it is currently insulated. Definitely bumping an old post here, but you've nailed it on the head Paul. The systems you describe have been in use throughout the UK for some time now. A municipal heating system throughout a town with the homeowners branching off the main systems. The average life expectancy of a geothermal system is nearly 25 years; compare that to the 13-year average life expectancy of conventional systems. Systems can raise a home's value because buyers like to purchase properties that will save them money.
A horizontal loop requires excavation work and digging around your house. You may have to cut down trees or shrubs to install the underground loop. The times it for sure makes sense is when there is a very large footprint of a new home or a very poorly-insulated and leaky building envelope of an older home. That same investment of $25,000 in a better thermal envelopewould likely reduce heating bills easily by 70 or 80%, perhaps more. Starting at depths of between 6 and 10 metres, the temperature of the earth is no longer influenced by variations in surface temperature, and stays relatively constant at around 8 to 10 C. So the underlying principle of geothermal heating and cooling is to use that consistent interior earth temperature to balance our wildly varying North American & Canadian surface temperatures.
The upfront investment can be $10,000 to $20,000 to have it installed. For example, in 2020, you can receive a tax credit for 26 percent of the cost of a residential geothermal system ($2,600-$5,400). Whichever loop type is required, bear in mind that the life of a typical geothermal heat pump is 15 to 20 years; loop systems can last 20 years or more.
If you have central air, you may have the ductwork necessary for installing a geothermal system. This can be determined by a site visit by our geothermal design crew. A geothermal system produces a 120-degree maximum temperature, which isn’t high enough to work with hydronic baseboard systems. Many people, however, still choose to install a geothermal system by adding appropriate air ductwork. Yes, a geothermal system uses the constant temperature of the earth to both heat and cool your home, which is a major benefit to these systems.
