    I'll go slower for you.

    In the UK, the majority of homes have gas boilers, the most common one being the combi boiler. Gas as in the vapour gas, not the liquid stuff known as petrol. Houses in the sticks tend to have oil boilers.

    Yes, they went deep, they dug a field out for the water that was pumped out, but not only that filled up, the muddy water ran down the village road. The house that had this originally installed ended up installing a gas boiler.

    The farmer was fed up that as soon as the power supplier to the heat pump was interrupted, it took it a day or two to get back up to speed, so he has both, air source heat pump and natural gas.

    It's cheaper to use/consume gas than electric, hence why my mates mother switched the air source heat pump off.

    Like I said, in the UK, stay clear of this crap technology until they can sort it, or if they can sort it. Just like EV's they're expensive unreliable junk.

    And what in the hell does any of that have to do with a heat pump?

    Sorry, you are absolutely confused and have absolutely no idea what you are talking about. Power supplier to a heat pump interrupted, and it took days to get it back?

    You obviously are not talking about a heat pump at all, I have absolutely no idea what in the hell you are talking about.

    Not too sure how behind the times America is, but in the UK, we have ground heat source pumps and air heat source pumps. The clue is in the name, they either extract the heat from the ground or air. Both are "heat source" pumps. With ground heat source pumps, the loop can be laid horizontally if you have sufficient land size, or you can bore down into the ground.

    When you bore down, you have to pressure pump the water out each time you add a tube, hence the amount of water.

    Did you not know??

    And that is not what this is, so you are as I said talking about something completely different and does not apply to this discussion at all.

    Heat pumps are one of those things that are best suited for certain type of environment. If you're in a climate where a resistance electric heater is enough then a heat pump will suffice and be more efficient. If you have a furnace I don't think it will be.

    Essentially every air conditioner is a heat pump. On an AC unit the heater part is typically the outside unit. This unit produces heat and it's just dissipated.

    I have an air source heat pump in one house. It works fine. The resistance supplement kicks on sometimes when temps fall below -10°F. How the structure is insulated has a lot to do with whether or not an electric heat pump can keep a structure heated.

    A family member (farmer) has a ground source heat pump. Has had it for at least 20 years. Works great. Very efficient. If the UK is having problems with such tech you are WAY behind the US. It sounds like your well drillers are incompetent. Wells for domestic water, heat pumps, and large diameter wells for irrigation are routinely drilled here and water never leaves the property where drilling occurs (unless it’s desired).
