Hey guys I need some more help. I wanted to post this separate from my other question since not ever contractor does GSHP.Here is the situation. My parents own a cottage future retirement home in the thumb of Michigan. He built the house about 35yrs ago and installed electric baseboard heat at the time as it was cheap (still is) and was easily done by himself. Well fast forward 35yrs we need a modern system. He never put in ductwork as it was out of his ability and price range at the time not to mention this is farm country.
We have settled on Geothermal because of operating cost. There is No Ng available and propane is out of this world. I need some help for brands and duct work questions. I am set on waterfurnace however my father is more lets see what the best price is. The other big brand is geocomfort which is waterfurnace. What I don't get is the geocomfort guys say waterfurnace is crap because they hold the patents on their parts so you can only get them from waterfurnace. But if geocomfort is waterfurnace don't the parts still come from waterfurnace or geocomfort only?
My next question is duct work. Most want to run a chase up to the attic then blow down into the second floor rooms. Does this work ok with geothermal since you move a lot more volume and a lower temp? Would it not be better to have the ducts lower down to the floor?
I am also wondering what is the deal with the new 2 stage units. I understand how they work but are they worth the money? Some contractors say they are good others say they are better in warmer climates for the air conditioning feature. He is interested as my father is a thermostat at 65 no higher. LOL oh yeah and furnace doesn't go on until Thanksgiving as you have to have something to give thanks for LOL. So it can run on the first stage until my mother cranks it up then the second stage kicks in or if they are away they can leave the temp lower on the first stage?
Thanks for all you help guys as geothermal is a HUGH investment compared to a 2k furnace. I know I will have more questions.
