Solar powered heated swimming pool
Historically swimming pool solar heating systems in the UK have been quite ineffective as they have utilised one of two methods. Either Black Panel matting where the pool water is passed through a plastic mat to harness the energy from the sun. This is moderately effective when the ambient temperature is warm but becomes a radiator when it is cold, cooling the pool water.
The alternative method is Evacuated heat tubes. These are up to 98% effective at harnessing the heat from the sun, however, up until now a heat exchange has been required to prevent pool water from passing directly through the tube as this will corrode them. This heat exchanger introduces efficiency to the system. The new compass pools solar panels are lined with Borosilicate (Pyrex) Glass which does not corrode and maximises this efficiency even on cloudy days. The frame is made of anodised aluminium and several panels can be coupled together. A small backup system is recommended for the beginning and end of the season and for unusual climate changes.
