HOW IT WORKS

Lo water heater Photovoltaic systems use special panels to convert solar energy into electricity and heat the water in the tank, which can be used for both domestic and heating purposes.

MODELS

There are different types of photovoltaic water heaters, namely:

  • with natural circulation, which exploit the fact that hot water tends to rise compared to cold water.
  • forced circulation, equipped with a pump that manages the water circulation, more efficient than the previous ones in the winter months.

And here are some models:

  • Frog, photovoltaic water heater patented by Sunerg equipped with double electrical resistance, simple to install;
  • Fothermo Boiler photovoltaic with 80L, 550W and 15,5A boiler
  • Fothermo photovoltaic boiler from 30L, 550W, 15,5A

  • Fothermo Boiler 10L Photovoltaic Boiler, 550W 15,5A

FEES

The average cost of a photovoltaic water heater is around €500. This isn't a low price, but it's important to keep in mind that the energy consumed to produce hot water accounts for approximately 21 percent of the electricity bill.
