“My home is comfortable and my utility bills are low. I have a 2000 sq ft house on a 4 acre lot in northeastern Wisconsin. I replaced my high efficiency propane furnace and air conditioner about 5 months ago with the WaterFurnace and and I have not regretted it once. The heat pump has a horizontal closed loop as the heat sink. There is a 40 gallon water tank to which the desuper heater is...” --aviator1013
“Just installed and put on line my Geothermal Climatemaster TT038. I purchased it through the internet from a DIY site geothermaldiy.com. (very fast service). Installation involved removing my present system (forced air electric) and putting the TT in the same location so I could connect to existing air plenum. With a trip to my local HVAC dealer, I got an adapter to make the unit to...” --
“I have had a WaterFurnace ES036 Heat Pump installed since August of 2004. I have had a few problems with the system in the past. One problem existed as a result of maintenance. Apparently when a Tech was checking the freon loop pressure a pin hole was created by the probe in the rubber gasket. As a result, over three months, the system lost freon thus causing the system to operate...” --D2003
“I paid almost $30,000 for the Tranquility 20 unit plus vertical ground loop (3.5 tons) for my 2000 sq. ft. home near Baltimore, Maryland. I expect to receive about half of this back (net $15,000) in the form of gov't subsidies. I did not shop around and probably overpaid somewhat. My major complaint is that the unit runs loud despite the fact that the product literature touts the unit's...” --hefret
“ I am not new to Geothermal heat pumps. I installed a Florida Heat Pump 4 ton water to air heat pump in my home when I built it myself in 1978. It was a single stage unit with a heat recovery unit to capture hot water from the waste heat in the summer. I was able to turn off my electric water heater in May and not back on until late Sept. because the heat recovery unit supplied all my hot...” --grifzila
“Very nice system. Hard to swallow $20K but not too bad when on the home mortgage. It was $14K more than the builder wanted to use and about $9K more than the upper line heat pump I was looking at. If I'd used the builder's choice, I'd saved $82 on my monthly house payment. Compared to the other unit I was looking at, I am paying $53 additional. My neighbor keeps their thermostat about the...” --tgkick
