In closed-loop systems, a collector is placed within the watercourse, with fluid circulating around a closed circuit. This is generally the best option for smaller projects, as it is cheaper and requires less maintenance.
In open-loop systems, water is abstracted from the watercourse, then filtered and passed through a heat exchanger before being returned to the watercourse some distance downstream. This can allow a larger heat extraction and may also improve efficiency, and is a good option for large-scale projects.
Are you considering a water-source or ground-source heat pump project ?
Renewables First have considerable experience and full project capability, from initial feasibility study through to system design and installation.
The first step towards a water-source or ground-source heat pump project is tell us about your project. The best way of doing this is via our tailored online Enquiry Form.
Once complete, one of our engineers will evaluate the site potential before contacting you to discuss the next stage of your project.
