Most units are easy to install, especially when they are replacing another forced-air system. This is known as a retrofit. Geothermal Heat Pumps can be installed in areas unsuitable for gas boilers or furnaces (fossil fuel appliances) because there is no combustion and thus no need to vent exhaust fumes. Ductwork must be installed in buildings [...]
It’s not recommended. There is a large amount of engineering required for a geothermal heating and cooling system. Thermal fusion of the pipe, drilling and trenching are procedures best handled by professionals. Nonprofessional installations may result in less than optimum performance, which could cancel out anticipated savings.
Typically trenches are spaced 1.0-1.5m apart while boreholes are spaced 3-4.5m apart.
This depends on soil conditions, length and depth of pipe, and equipment required. A typical small installation can be completed in one or two days.
With the vertical installation, time varies with conditions on the site such as type and depth of the overburden, type and hardness of the bedrock, and the presence of aquifers. Typical drilling times are one or two days; total installation can usually be accomplished in two days for a small system.
Horizontal installations are simpler, requiring lower-cost equipment. However, they require longer lengths of pipe due to seasonal variations in soil temperature and moisture content. Since a horizontal heat exchanger is laid out in trenches, a larger area is usually required than for a vertical system. Where land is limited, vertical installations or a compact horizontal installation [...]
Geothermal Heat Pump systems are generally sized to meet all your heating and cooling needs. Our engineers can provide a heating and cooling load calculation to guide your equipment selection.
