Ullapool sea source heat pump visit Saturday 19 August

17 August 2017

A small group of TBI members went to Ullapool last Saturday to see a domestic sea source heat pump installation.  Among them was TBI Convenor Martin Sherring, who writes

"The Black Isle is surrounded by the sea, which stays at a fairly constant temperature all year round, so why don’t we use the sea as a source for heat pumps, instead of drilling boreholes? A small group of us went to Gus Horsburgh’s house just outside Ullapool to find out.

"For those who aren’t familiar with heat pumps, they work using exactly the same technology as a fridge – but whereas a fridge is mostly concerned with cooling its contents, and only slightly warms the room it’s sitting in, a heat pump warms the house, and only slightly cools the “source”. And the source can be air, ground or water; it doesn’t have to be particularly warm, although the warmer it is, the more effective the heat pump."
