Water Source Heat Pump
Water can be used as an alternative to the ground or air as the energy source for your heat pump. Water has very good thermal conductivity properties so if you have access to moving water (river, lake or even the sea), this can make for a very efficient heat pump.
About Water Source Heat Pump
There are 2 main ways that water can be used. Closed-loop: similar to ground source, pipes or coils filled with glycol is laid on the river/lake bed to absorb energy from the water. Capital costs are reduced as no trenching is required. Secondly, Open-source: this is where water is pumped to a heat pump and the heat pump absorbs the energy directly from the water. This method is ideal if you don’t have ownership rights to the body of water in question but it requires filtration and pumps which mean greater maintenance and service considerations
Water source heat pumps are the cheapest to run – typically offering efficiencies of 450-500 per cent – and have a lifespan of 25 to 30 years, compared to an average boiler’s lifespan of 10 to 12 years.
If you plan to install a water source system (closed-loop or open-source), water temperature data is required to prove that the min water temperature is rarely lower than 4’C. Environment Agency licences may also be required.
Design & Consultancy
All renewable energy systems need to be designed so they are specifically tailored to the premises. This is essential to ensure you qualify for the Government renewable energy incentives such as the Feed-in-Tariff and the Renewable Heat Incentive. We look at all aspects of your building so we can advise on how it can be made more energy-efficient and recommend the type of technology that suits you or your business.
