Is GSH really worth the huge installation cost ?
I got an estimate for my house, 9385+VAT for the ground loops, tanks and pumps, 3K for the under floor heating to go with it, plus say 2000 install charges. That will get me (at best) 4 units of heat out, for each unit of electric in, 3 from the ground, 1 from the spare heat of the electric.
With the cost of a simple electric fires, install cost is 1-2K.
If I need 8 KW to heat my house on a very cold day, and I heat it 12 hours a day, for say 150 days a year.
I work this out as taking 10+ years to get to break even. Once you get to breakeven costs for the GSH are attractive, but its a long haul to get there.
Do other people get the costs in the same ballpark ?
I then took a look at a coal fueld boiler, and got the break even point with GSH into many decades, long past my death anyway. Does this sound reasonable ?
Gas is out of the question, oil seems a bad choice, there is only one delivery agent in my area who use a tractor. I have no room to turn a waggon at my house, but a tractor, in summer, can turn in the fields.
