5 Ton WaterFurnace Envision and earth loop. After the install, this customer downloaded “Smart Meter” data from Idaho Power. He compared energy consumption over the last two years for the same two-month period. The WaterFurnace system was using half of the KWhrs per heating degree day. This is great data considering we replaced an air-source heat pump which are more efficient than std. gas furnaces.
Even better is the fact that the customers keep their home warmer now, and still save 35% – 50% on energy each month. Aside from the smart meters, we have installed metering devices directly to the ground-loop heat pumps on several systems. The customer can look (at any time) and determine exactly what they are spending to stay comfortable.
