If you have the space, save the money! Installing a GHP (geothermal heat pump, ground source heat pump) is always less expensive to install horizontally than vertically. The energy saving benefit is exactly the same. The amount of space needed varies depending on the size of the home, but can almost always be done in new building situations.
One of the best parts about installing a GHP horizontally is the fact that it doesn’t have to cost more than traditional heating methods. With the availability of rebates for 30% or more of the total system cost, GHPs are competitively priced with far superior energy efficiency, greatly reduced carbon emissions and improved indoor air quality and indoor comfort.
Geonomic Developments recently installed a GHP horizontally for an adult care facility just outside of Vancouver, WA (Battle Grounds, WA). See the before and after. Including rebates, the total system cost was less expensive than our client had been quoted for both an air source heat pump and high efficiency furnace. GHPs on average use up to 80% less energy, have the highest indoor air quality, lowest operating costs and the quietest operation. When building your next home, let Geonomic Developments show you why building green doesn’t have to cost more.
