I have just ripped out my heat pump as I think I have been sold a pup. Back to oil i'm afraid. I'm left with 600m of ground coil. Anyone know if there is any profitable use for this alternative to it's original purpose?
cheers

It would add to the information base if the problems could be explained to try and sort it out.There could be all kinds of problems with the installation or method of use requiring tweaks to get it working as it should.

One of the items on the list was lack of  insulation under the underfloor heating, also there were only radiators upstairs.    That would be quite a struggle  for a low temperature heat source.

Thanks for the posts,
There were no real problems with the heat pump which is an excellent early model alpha innotech 11kw machine. As Dhaslam rightly remembers the installation was the problem. Basically the machine was inappropriate for a stone built 150 year old farmhouse and the installation was very poor.....cr*p underfloor insulation and over reliance on radiators. I've got myself to blame really for my ignorance at the time of installation. Great to have forums like this to educate oneself!

My question was really to see if anything can be done with the ground loop. I run a small microbrewery and was wondering if there was a low tech way of using it to keep a conditioning room or tanks at a stable temperature perhaps by simply circulating fluid through the ground. (Beer would mature well at the same temperature as the ground and lager would also ferment ideally at this temperature.)

Many thanks

A ground loop is about 5-10C isn't it. Keep a greenhouse frost free.

is that not a bit cold for fermentation etc.. ?

if it is ok, it should be pretty easy to pump water around the loop, and use a heat exchanger to keep the plonk at the right temperature ?
