Sounds like a small heat pump what does it actually achieve?

It heats our (fairly) small house quite nicely!

Very happy with it - when it's working well - which, over the last 15
years has been most of the time.

Sucks heat out of the ground via 3 x 100m coils of plastic pipe buried
under our polytunnel and produces circulating central heating water to
feed our radiators.

The manufacturer reckons that the system produces 3 - 4kw of heat for
every kw of electricity consumed.
