“Bore holes and heat pumps”
|At the Fife Show, Scotland, in 2017, local resident Mike Peter explains how heat pumps can be beneficial and the growing local interest in the area from farmers.|
Martina McGuiness: And you were saying your friend drills bore holes. Is there been more interest in that, of late?
Mike Peters: Aye. A lot of that has been down to heat source pumps for heating in the new building sites up in North Aberdeen but a lot of it, round here, is for the farmers, in case they run out of water.
Martina McGuiness: What does the heat source pump work? What do you need the water for?
Mike Peters: It comes from temperature down in the ground. You can drill a hole anywhere, at a certain depth. Better in rock. And it’s always, I can’t tell you exactly what temperature is but it’s just like a U tube. You pump water down the hole and, by the time it comes back up the hole, it’s absorbed the heat from the ground. So it’s not coming up hot hot, it just takes the chill out of it. It not for the heating.
Martina McGuiness: And then you circulate the water through your heating system?
Mike Peters: Yeah that’s exactly right, yeah.
Martina McGuiness: So is it a closed system then? You’re not actually extracting water you’re just
Mike Peters: No just a heat exchanger, yeah.
Martina McGuiness: Okay, so you wouldn’t actually be extracting water?
Mike Peters: No, no. It’s a special. There’s a chemical in that heat exchanger that goes round which is even better at absorbing heat from the rock. Yeah.
