From reading the FAQ on heat pumps, it sounds like having a well is a good thing?   For a property with a well, I presume trenches are unnecessary - leading to a cheaper installation cost?
The reason I ask is that my parents have a well at home, and were recently left standing when a solar water heating installer backed out on them - so I know they are interested in going green.   I plan to mention it to them, but before I do I'd like to be sure of how much it would likely cost, and what capacity in kW is likely to be required (detached cottage in the countryside, 7 rooms in all, double glazed and loft insulated).

I assume the well you are talking about is for the domestic water supply, if this is the case it is unlikely to be of a major benefit as it probably won’t be deep enough on its own to use with a heat pump.

Solar might still be a good option, if you post details here there may be an installer close to your parents.

I've just had a good idea. Why not put heat pump heat exchangers in mains water pipes. Obviously, this would have to be done with cooperation from the water companies but it might be cheaper than laying a 2-300m ground loop...?  Cool

I suspect they would run the risk of freezing up.

I have a well on my property which I am installing with the 9Kw unit to heat my Sussex Cottage.
This well is more than 100 feet deep and I am using the water direct via a filter and consider this as a good supply, hopefully will not be proved wrong when I get it up and running.

My parents have a bore hole for their domestic water supply. It's over 100 feet with a submersable pump at the bottom.
Could this borehole be utilised for heat gathering/converting ?

just a thought,,,,,,

Yes, you can use a borehole, but as you need somewhere to dump the water back, you will need a second borehole at least 10m away to receive the water. You will also need to make sure your pump is sufficient to provide enough flow
