Geowarmth Heat Pumps

Solar thermal heating for domestic hot water is a well established technology to harness solar energy. From March 2011 annual cash back payments are available under the Renewable Heat Incentive.

Solar heat is free and in the UK we typically receive around 1,000kWh of solar energy per m2 per year. This means solar energy can usually provide 50-60% of a property’s domestic hot water needs.  Solar thermal hot water heating is a leading choice of low carbon technology.  There are no CO2 emissions on site when hot water is heated by solar panels.  The roof panels absorb solar heat and transfer it via a coil in to the water in a hot water cylinder or thermal store.  The system is extremely efficient with low maintenance.

Solar thermal panels require a southerly unshaded orientation.  They are normally installed on a pitched roof.  The ideal roof inclination is an angle from 30-50oC from the horizontal, which is the typical angle of most domestic pitched roofs.  The panels can be fixed to both slate and tile roofs.

Where a pitched roof is not available the panels can be installed on an inclined frame on a flat surface.

A hot water cylinder is required.  Solar thermal does not always work with combination boilers.  A cylinder specifically designed for solar thermal provides the best solution.  These are usually unvented mains pressurised systems.

Geowarmth offer both flat plate and evacuated tube systems for residential and commercial buildings.
