A key component of a WSHP system is the heat exchanger or heat collector that harvests the heat from the water and transfers it into the building via a heat pump.
The core of SeaWarm is its state-of-the-art all-plastic heat exchanger. This unique technology is engineered to maximize heat extraction from water, ensuring superior performance and durability.
By leveraging the stable temperatures of seas and oceans, SeaWarm provides consistent and reliable heating. The high specific heat capacity of water ensures efficiency and sustainability in energy usage.
SeaWarm technology can also heat your home/business through ice formation in the heat exchanger. The Latent Heat of Ice Fusion is 80x larger than the heat capacity of water. This feature ensures that under the most inclement conditions a stable and reliable heat source is available.







Here’s a short video report from STV News that clearly explains how SeaWarm’s pioneering pump technology works and showcases its impact in Scotland’s coastal communities
Our SeaWarm model supports excellent heat pump efficiency, thanks to its state-of-the-art HotTwist technology. This enables local scale residents and businesses to harness the energy of the sea, offering a robust and efficient heating solution.
SeaWarm champions eco-friendly design, showcasing the brilliance of water-source heat pumps in reducing carbon footprint. It surpasses the capabilities of typical ground or air source heat pumps and ensures a truly sustainable, long-term heating solution.
While the SeaWarm heat exchanger is coupled to a standard ground source heat pump, it collects heat from water bodies instead of the ground. Water can store ~2x more thermal energy in a given volume than the ground, and ~3400x the thermal energy than air, offering a unique edge in efficiency over traditional ground or air source heat pumps.
Water sources, particularly seawater and minewater, buffer atmospheric temperature extremes providing a consistent year-round heat source and an excellent seasonal coefficient of performance (SCOP). SeaWarm offers waterside properties and businesses the opportunity to take advantage of these efficiencies through its versatile installation, making WSHPs more widely available.
The SeaWarm heat exchanger can be installed in a range of settings e.g., in a basement, outdoor, or even buried, to provide a truly versatile installation. The overall system can be designed to harvest heat at distances up to 500 m from the water source, making water source heat pumps more widely available.
SeaWarm is not just for residential use; its modular design enables larger buildings to take advantage of nearby water sources and SeaWarm’s excellent efficiencies. This also means SeaWarm is well-suited to local, ambient temperature district heating systems, providing excellent opportunities for housing developments or waterside apartment complexes.
SeaWarm’s HotTwist technology has been specially designed with easy maintenance at the forefront. Combined with specific maintenance features on the tank, this ensures long-lasting performance and peace of mind.
When comparing SeaWarm with a ground source heat pump, the differences are clear.
SeaWarm’s water-source approach eliminates the need for extensive ground heat exchangers or boreholes, offering a more efficient and less invasive solution.
Ground source heat pumps using boreholes take heat out of the ground faster than it is replenished, leading to a gradual decline in the ground temperatures and a reduction in heat pump efficiency. SeaWarm’s water-source approach targets a truly sustainable heat source, ensuring long-term energy security. The water source is being continually replenished.
