Yes! Many Geothermal Heat Pump systems are being installed using a multitude of systems hooked up to an array of buried vertical or horizontal loops. This simplifies zone control and internal load balancing.
Geothermal Heat Pumps save money, both in operating costs and maintenance costs. Investments can be recouped in as little as three years. There is a positive cash flow, since the energy savings usually exceeds payment on the system.
The initial investment for a Geothermal Heat Pump system is greater than that of a conventional system. However, when you consider the operating costs of a geothermal heating, cooling, and water heating system, energy savings quickly offset the initial difference in purchase price.
You can expect an installation charge for any electrical work, ductwork, water connection, and other provisions or adaptations to your building that are required. Our engineers can estimate these costs in advance if required.
The reduced peak load requirements would allow utilities to serve more customers and to lower fixed costs per customer, thus offsetting some increased variable costs. This would result in less cost per kilowatt, since fixed investment for new capacity is high.
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.
