So I have decided to go with geo again. My current system was a 3 ton open loop Hydro heat. I have a 33,000 btu gas fireplace that will keep the house at 65 in cold winter days as we had a power outage a few years back, so no heat strip needed. I had dedicated hot water but bought a Geospring hybrid water heater so not sure a desuperheater is a good choice in this new unit. I was curious about the COP ratings. I did get a quote on Climate master and the price is just over $2000 difference for the tranquility 22 to the 30. Cop just over (4 for the 22) and just over( 5 for the 30.) Will I get enough savings to recoup that $2000 or not. I have read and heard Climate master, and Water furnace are top brands. All brands are on the table. I like it to be cheaper to repair after the warranty goes off. I read Bard has cheaper solenoids to operate their furnace instead of expensive computer boards so that is a top choice for me also. KWH got as high as 2700 this winter but Freon was leaking out and had a bad connection on a breaker going bad, also would have contributed to this.
