How does a Geothermal Heat Pump system heat water for my building?2019-03-06T08:49:47+00:00

Using what is called a desuperheater, Geothermal Heat Pumps turn waste heat to the task of heating hot water. During the summer, when the system is in cooling mode, your hot water is produced free as a byproduct of the thermal process. In winter, with the heating mode, the desuperheater heats a portion of your hot water. Desuperheaters are standard on some units, optional on others. Stand-alone systems that will heat water all year around can be purchased.

How much space does a Geothermal Heat Pump unit require?2019-03-06T08:49:12+00:00

What about comfort?2019-03-06T08:46:20+00:00

A Geothermal Heat Pump system moves warm air (32-40(C) throughout your building or business via standard ductwork. An even comfort level is created because the warm air is moved in slightly higher volumes and saturates the building with warmth more evenly. This helps even out hot or colds spots and eliminates the cold air blasts common with fossil fuel furnaces. For heating only systems in slab or underfloor radiant heating is a very popular choice where (32-40(C) is circulated via a series individual zoned floor piping. Radiant floor heating is even more economical as no fan power is required. In some building types the in slab piping can also be used for cooling.

How would increased use of Geothermal Heat Pump systems affect electricity cost and availability?2019-03-06T08:41:15+00:00

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.

Are Geothermal Heat Pump systems difficult to install?2019-03-06T08:40:14+00:00

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 without an existing air distribution system.

Can I install a ground source heat exchanger myself?2019-03-06T08:39:36+00:00

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.

How far apart are trenches and vertical boreholes spaced?2019-03-06T08:38:42+00:00

Typically trenches are spaced 1.0-1.5m apart while boreholes are spaced 3-4.5m apart.

How long does it take to install a horizontal system?2019-03-06T08:36:52+00:00

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.

How long does it take to install a vertical system?2019-03-06T08:36:28+00:00

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.

What are the advantages and disadvantages of the horizontal and vertical installations, respectively?2019-03-06T08:35:53+00:00

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 can be ideal. If regional soil conditions include extensive hard rock, a vertical installation may be the only available choice. Vertical installations tend to be more expensive due to the increased cost of drilling versus trenching, but since the heat exchanger is buried deeper than with a horizontal system, vertical systems are usually more efficient and can get by with less total pipe. A Geomaster engineer is able to help you decide which configuration best meets your specific needs.

Is it advisable to install a Geothermal Heat Pump system large enough to handle my total heating needs?2019-03-06T08:35:03+00:00
