Ground Source Heat Pumps

You can see my question on the site feedback forum under the spam buttons heading and MSEAndrea kindly reinstated this discussion
I was bewildered as to why post was pulled, specially as questions were beginning to open up a reasonable debate regarding GSHP, an area that has interested me for a long time!

Thanks Chippy. Sorry for the long delay in answering, but the thread has only just been reinstated. Do you have any info or articles about this village, as would be interesting reading.
I monitor my pump here and have not seen any performance reduction over the last 5 years. If you take the basis that in winter, a heat pump is running circa 10 hours per day, with a flow rate on a ground loop of 11 ltrs per minute (for a 11Kw output unit) , then the recharge time is longer for the loop. At the moment, I am getting 6.0C in with 2.0c out Outside temp 2.0C and snowing today). As the heating need is reduced in say Spring, this then starts to rise and during the summer we get even higher inlet temperatures. Some people use the ground loops to slightly cool the house, as passive cooling in the Summer months, when outside temperatures are higher than the feed in temperature
Sorry Geo,
Can't remember where I read it. It was mentioned by another engineer months ago and I managed to find it on google. Just had a google and can't find the article as we speak.Happiness, is a Kebab called Doner.....:heart2::heart2:0 -

The ground loops recharged temperature at a higher level, than 5 years ago in the same period, through less input, but you have to remember that they pull out more heat in the winter, on a longer operating time.
I did ask our engineers, who solely deal in heat pumps, but I could not repeat the reply!!! The engineer that told you was a geothermal guy I presume ?As Manuel says in Fawlty Towers: " I Know Nothing"0 -
David Nicholson-Cole from Nottingham has a very good blog about his home which has PV, solar collectors and GSHP (two boreholes). It does have a lot of data on it as it seems to have been run as a university project as well as his own home eco project, so is more "scientific" than some of the claims bandied about. Google "chargingtheearth".0

This MSc Thesis paper may go some way to explaining loss of thermal recharge, although I reckon you will know of this possibility.

Thanks,
I have only skimmed that section and we are not allowed to quote from the thesis(copyright) but it does seem to confirm that under some conditions what 'thechippy's' read has some validity for boreholes.0 -
Hi,
I did notice copyright, I have edited and added info re; copyright.0 -
