Solar thermal water heating

Solar heating solutions from BaxiA solar thermal water heating system uses the free energy from the sun to heat domestic hot water. 

The technology is simple, effective and sustainable which is good for the environment - now and in the future.
Baxi has three powerful solar thermal heating options:

  • Baxi Solarflo on-roof collector panels
  • Baxi Solarflo in-roof collector panels
  • Baxi Solarflo evacuated tube collectors

Effectiveness of solar heating

During the summer months, a solar water heating system can generate up to 90% of the hot water required for an average household; even on duller days some hot water can be produced, with the remainder being provided either by a conventional boiler or electric immersion heater. On average, a well-designed solar heating system will generate around 55% of the annual domestic hot water demand while also substantially reducing carbon emissions.
