The EPA lists geothermal systems as the most environmentally responsible choice on the market
Geothermal heat pumps continue to become more popular as a residential heating and cooling solution. The cost of these innovative systems has come down a bit in recent years, and there are federal and state tax incentives that help with affordability. While the investment is still considerably higher than implementing a more conventional alternative, a geothermal unit typically recovers the cost in under five years. This is because of 400% efficiency ratings. The high efficiency of this type of system cuts heating and cooling costs by around 50%. Plus,with the addition of a simple valve, the heat pump can provide a virtually free source of hot water. A geothermal heat pump takes advantage of heat stored underground. Even if the outdoor temperature drops below freezing, the underground temperature remains constant. The system utilizes an underground loop that absorbs the heat and transfers it by way of a liquid or refrigerant into the home. There is no combustion process, which eliminates concerns with carbon monoxide and other greenhouse gasses. The heat pump creates no fumes, has no hot surfaces and won’t dry out of the indoor air. In cooling mode, the system acts just like a traditional air conditioner and draws heat out of the indoor environment. Geothermal heat pumps are especially effective at dehumidification. Operation is safe, clean, quiet and wonderfully environmentally responsible. The EPA lists geothermal systems as the most environmentally responsible choice on the market. 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 and should provide a lifespan of twice that.
