Geothermal heat pumps are significantly more expensive than more conventional temperature control options. However, these innovative systems combine both heating and cooling capacity and also provide a virtually free source of hot water. Using only a minimal amount of electricity to run the heat pump and draw from the abundant and free energy stored naturally in the earth, the operation is extremely cost-effective. Geothermal heat pumps take advantage of the relatively stable fifty to sixty degree temperature found underground all year round, regardless of the weather conditions. The system simply transfers existing heat between the inside of the home and the ground. The most energy-efficient conventional system achieves up to a 98% efficiency. A geothermal heat pump offers efficiency ratings anywhere between 300 and 500%. Along with significantly lower running costs, there are available tax credits to help with startup expenses. Because the system can save up to 70% on utility bills for heating, cooling and hot water, the investment is usually recovered in under five years. There’s also the benefit of exceptional comfort. The system doesn’t dry out the air during the winter, handles excess humidity during the summer and helps to filter out air contaminants all year long. By eliminating the outdoor condenser unit, geothermal heat pumps are very unobtrusive and quiet. There is no combustion process, eliminating concerns over carbon monoxide, fumes, odors and greenhouse gasses. They are considered by the US Environmental Protection Agency to be the most environmentally responsible choice for heating and cooling. Another advantage is that the one unit handles both heating and cooling. There are fewer moving parts to wear out, reducing the chance of malfunction. Because the heat pump is installed inside the home and protected from the weather, it can be expected to last upwards of twenty years. The underground loop is warrantied for fifty years.
