This eco-friendly heat pump offers a sustainable and versatile heating solution, saving energy costs and reducing carbon emissions.

SeaWarm’s heat pump can harness energy from any water body, offering a more sustainable solution for powering homes and businesses.A new type of equipment is being trialed at Edinburgh University to sustainably power homes and offices in Edinburgh, Scotland.

This innovation has been developed by SeaWarm, a University of Edinburgh Spin-Off Company that harnesses the power of water sources from seas, rivers, ponds, and even mine water to provide efficient heating and cooling for homes and businesses. Known as the Water Source Heat Pump , the system utilizes thermal energy stored in these water bodies.The system features a heat exchanger, such as SeaWarm’s HotTwist technology, which is designed to extract heat from the water. The heat exchanger collects thermal energy from the water and transfers it to the heat pump, where it is compressed to a higher temperature suitable for heating purposes. This system is optimized for stable water temperatures, ensuring consistent performance, and can even operate efficiently in extreme conditions by utilizing the latent heat of ice fusion, according to the company., SeaWarm’s heat pump is currently being tested by Edinburgh University in an affordable housing project near the Firth of Forth, close to the Forth Bridge, at a gold-mining museum in southwest Scotland, and in a commercial greenhouse in Fife. The report also mentioned that another heat pump system is planned for installation this summer at the Scottish Seabird Centre in North Berwick, which will also harness energy from the Firth of Forth.“While the SeaWarm heat exchanger is coupled to a standard ground source heat pump, it collects heat from water bodies instead of the ground,” the firm explained. The SeaWarm system has a key component – glycol, a liquid used as an anti-freeze agent. Glycol circulates through looped tubing within the heat exchanger, where it absorbs thermal energy from the water source. This warmed glycol is then compressed in the heat pump, raising its temperature sufficiently to heat water for various purposes, such as radiators and baths. As the glycol travels through the system, it cools down and repeats the process, ensuring continuous heat transfer from the water source to the building, even in colder conditions. In fact, the team of scientists from Edinburgh University said that their designs called SeaWarm and RiverWarm can also harness energy from frozen water. “It’s about trying out a whole series of constellations, but at the heart of it is the same technology,” stated Prof Chris McDermott from Edinburgh’s school of geosciences, the lead designer.that the system would be more expensive to buy and install than an air source heat pump but cheaper than a ground source heat pump when its final version goes on sale. He added that the HotTwist system is said to deliver 350% to 400% more heat than the electricity it needs to operate, which is comparable to the most efficient air source heat pumps.This eco-friendly technology provides a sustainable and versatile heating solution, also offering significant savings in energy costs and carbon emissions.As a quirky and imaginative multi-media journalist with a Masters in Magazine Journalism, I'm always cooking up fresh ideas and finding innovative ways to tell stories.
