ESTG: Thermal – Solar Water Heaters

Why choose a solar water heater?

A solar water heater converts sunlight directly into thermal energy for hot water. It is a logical extension of existing or new PV-systems. By producing hot water directly from solar energy, reliance on the electricity grid is reduced, and the overall efficiency of the energy system increases. Our range offers solutions ideal for energy-efficient homes, commercial projects, and all-electric applications.
