‘At heart it’s the same technology’: the heat pump that uses water instead of air

Equipment being trialled in Scotland extracts warmth from nearby water sources to provide homes with heating

The equipment can use sea water, rivers, ponds and even mine water to heat radiators and water for baths and showers, using the same technology as in air source heat pumps.
