Low Cost Heat
Our sources of energy are finite and we need to start looking at alternatives. This is one possible environmentally friendly way...In an empty warehouse in Oxfordshire sits a large block of ice, which pumps out enough heat to keep a nearby office warm. Yes, you read that correctly. Heat from a block of ice. This oversized ice cube is an essential part of a clever heating system called a heat pump
...Heat pumps work just like fridges, by sucking heat from warm things and moving it elsewhere.
...That's the thinking behind domestic heat pumps. There's heat everywhere, in every substance over -273C (absolute zero). The block of ice in the warehouse is kept at -10C, warm in comparison. Plenty of heat to be had from that.
...Domestic heat pumps can also suck warmth from the ground...then put the heat to work in your radiators and hot water taps.
