geothermic heating - counterproductive?

Recommended Posts

I'm renovating my chateau in France, and am considering 'geothermic' heating (pipes under the ground - got plenty of THAT!).

 

But I just heard that it's self-defeating - the extraction of heat kills the bacteria down there who are responsible for generatig the heat, so it stops working after a while. Anyone got any definite information on this?

Assuming we're talking about geothermal heat pumps, it's just taking advantage of the ground being warmer than the air in Winter and being cooler than the air in Summer. Unless it came to the point of truly massive scale heat pumps being used everywhere, I can't see how we would heat or cool the ground that much.

 

I could be wrong but I've never heard this theory about bacteria before and I suspect it isn't true, at least not for a residential size system.

I'll be honest, I've never heard anything about bacteria even having anything to do with the heat extraction process.

 

Dr Bubb has made a good post regarding the basics of how a heat pump works, but i'm sure you have already seen this

My intrest in this technology is in the tooling that is used within the instalation of these heat pumps, one of my customers has actualy been installing these for a while now http://www.digandfit.co.uk/ or you could even tryhttp://www.iceenergy.co.uk/default.asp i'm sure if you have any doubts about using this technology, they could set you straight.
