Sustainable Energy Technologies offers a high quality split solar thermal water heating system. This system uses solar collector panels sited on the roof and linked to a hot water tank situated inside the building.

• Fully automated system, requires no user intervention once installed
• Collectors can be mounted on the roof, in the garden or on walls
• Single or twin coil hot water tanks
• Indirect system, protected from any lime scale or frost damage
• Pressurised or Drain Back Systems & Zero Carbon systems
• System designed with solar software showing system outputs & savings
• Professional installation with guarantee

A solar hot water system works like this...

An electronic controller constantly compares the temperature of the solar collectors, usually located on the roof of the building, with the temperature of the water in the bottom of the hot water cylinder. Whenever the collectors are hotter than the temperature in the bottom of the cylinder, the controller switches on the solar systems circulating pump. A solar grade anti-freeze is then circulated through the collectors to the cylinder’s heat exchanger, heating the water inside the cylinder in just the same way as a central heating boiler.
