Hot water
in roof, mounted on walls, or on a frame construction to achieve inclination on flat roofs.
A commercial system sized to support a care home with an occupancy of 50 will typically require 12-24 flat plate collectors each 2.24 m². Smaller systems servicing up to 12 occupants will employ just three to four panels. Sized and installed correctly, a single solar thermal collector can contribute up to 1400kWh per annum, providing electricity savings of £300 and more importantly reducing emissions of CO² by 322kg.
It is important to recognise that solar thermal differs from solar photovoltaic, or Solar PV as it is known. Solar PV uses solar cells in a panel to convert the solar energy into electricity that can be stored, used as required, and even be sold back to the grid. Solar thermal works by a process of fluid heating in the collector panels that is then transferred via indirect heating in the cylinder into the hot water system. This requires basic plumbing for its installation and a minimum 3m drop to ensure flow. This does mean it is really only suited to installation on a building, rather than in the grounds, although that helps reduce the

threat of vandalism compared to frames installed on ground level. Giving consideration only to the hot
water system, solar thermal is still more advantageous compared to equivalent- sized solar PV systems. For example, a 4kW solar PV system and the equivalent solar thermal system will cost almost the same to purchase and install, with minimal operational costs, but solar thermal will exhibit a much smaller physical footprint.
A typical 4 kW PV system would require 16 collectors at 25m², whereas this would be matched by just three solar thermal collectors for a total footprint of 6.6m². This makes solar thermal a better choice for buildings with reduced roof space, especially if sustainable projects are intending to introduce a mix or solar thermal, heat pump and solar PV. The silent operation of solar is also a consideration factor for residents’ comfort.
Up Assisted standing, transfers and rehabilitation
Suitable for those who require assistance when standing but are able to contribute effort. By encouraging user participation, the Up can play a supportive role in rehabilitation, mobilisation and independence.
