Solar Water Heater Types
Werstahl Solar water heaters come with two types of boilers, one that utilizes two energy sources and one that utilizes a third alternative source:
- Double energy: This type of solar system, produces hot water by utilizing the energy of the sun and also by the use of an electric heater, for the days that are very cloudy and the solar energy is not efficient.
- Triple energy: This type of solar water heater, has the ability to utilize a third energy source, through the use of an extra heat exchanger inside the water tank. This extra energy source could be a gas or oil boiler, a heat pump, a wood burner or anything similar.
