Solar Hot Water Heating
Solar hot water heating systems provide a cost effective solution for heating the water used for washing and bathing.
Solar Hot Water Heating Systems
- Provide up to 80% hot water per year for 30 years
- Fully automated and require no user intervention once installed
- Solar Collectors can be mounted on the roof, in the garden or on walls
- Indirect system, no scale or frost damage
- Pressurized or Drain Back Systems & Zero Carbon systems
- System designed with solar software showing system outputs & savings
- Professional guaranteed installation
A solar water heating system works like this...
 An electronic solar heating 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 solar hot water cylinder. Whenever the solar collectors are hotter than the temperature in the bottom of the solar cylinder, the solar controller switches on the solar systems circulating pump. A solar grade anti-freeze is then circulated through the solar collectors to the solar cylinder's heat exchanger, heating the water inside the solar cylinder in just the same way as a central heating boiler.
95% Solar Hot Water coverage from May to October
Our clients have informed us that the solar heating systems we have installed will usually heat all of their daily water consumption from May to October. Outside of these months they still get a satisfying amount of heat from the solar system on clear and cloudy days. You should expect, on average 95% in the summer, 60% during the spring and autumn and 30% in the winter.
Correct sizing is essential for solar
Size of solar collector area and solar cylinder depends on how many people you will need to supply. If you want 70% of your hot water supplied by solar expect 2.5m2 of collector area and a 200 litre cylinder on small installs for 1-2 people, 5m2 of collector and a 300 litre cylinder for 3-5 people, 7.5m2 of collector and a 400 litre cylinder for 4-6 people for flat plate systems. Vacuum Tube solar collector area will be slightly smaller.
