Hi all... Wondering what advice I need to hear about my geothermal project. Our home is aprx 3400 sq.ft (livable space). The geothermal rep. talks about an 8 ton unit. He says a 4 ton unit will work but it will need to draw more emergency (electric) heat than the 8 ton unit and so recommended the larger size. He says it will be about 400% efficient. Sound right?
- The original portion of the house is an older two story farm house with an addition of 15'X30' and an addtion of 30'X40' [there is also a 16'X14' 4-season room which is currently coooled/heated when needed by a 'hotel' type unit]. - Planning an open pump and dump system into a farm pond 1/4-1/2 acre) - The existing water pump is 1/2 horse -- they talk about upgrading to a 1 1/2 horse variable speed pump with a small water tank bladder... Is it useful to also have a seperate water tank? to reduce wear and tear on pump? to save money?
