I thought it might be of interest to the forum to film an actual working ground source heat pump. Filmed on me new action camera of course (there's no stopping me now  ). |

I've noticed a few getting fitted out in the countryside when they build a new home on an old plot - no more free-standing diesel tanks in the garden!

Our friend the Sun heats the earth. I read recently that it provides 1KW of heat into 1M2 of the earth. Our Star is an amazing resource!!
Most of the year a Geothermal HP can extract from an earth that sits at a constant 5Degrees C.
So in simple terms, a Fridge can cool <5Degrees C, so reverse a Fridge & it can produce >Degrees C from the ground.

Thanks for posting the video, Tappy. Is that your setup? How effective is it? Could it reliably heat a house through a cold winter as the only heat source? Or would you need a backup? Is it suitable for rads, or only underfloor? What sort of maintenance is required?
Only experience of GSH was 13 years ago staying in a cottage in Devon. One thing I remember was the plant was quite noisy.

How does the taxman make his bit out of the job cause he'll not like losing all that gas revenue? |

It supplies a meeting room and training centre Woody.I sneaked into the boiler room to shoot the video,so no it's not at my house. My thinking on it is that if you can afford comfort levels of heat in your home using gas,oil,electric,SC, then you should be able to save a Bob or two with this system. However, if you want to switch something on to get warm quickly then turn it off then it's not for you. The noise in the background is all the noise you get from a ground source unit,air source though are very noisy. Cheers Tappy,

I paid a bit more for the camera this time tom and I reckon it's a better quality picture as well (slightly more wider angle lens too). The technology behind these heat pumps certainly takes a lot of getting your head around. Minus 273 degrees C is thought to be the coldest temperature that you can ever have. Beyond that there is said to be no more heat to be had, however, 273 degrees C is a hell of a lot of heat to be had below the freezing point of water. I'm totally fascinated by this subject despite it being too much to really get my simple head around!  |

I know what you mean Tappy, Its all new to me, very interesting and makes perfect sense to use the heat in the ground and from the air, Its the future,  |
