Helioset drain-back 150L, 250L
Helioset 150 and 250: drain-back solar systems
Helioset 150 and 250 liters drain-back is a solar water heater suitable for individual houses. It meets the hot water needs of families of around 2 to 5 people. You can add an electric or gas back-up to cover the needs in less sunny periods or when the demand for hot water is particularly high.
The drain-back principle limits the risks of overheating in summer and freezing in winter, in regions where the temperature drops very low. In addition, the drain-back simplifies the sizing of the installation and reduces the space required for the system.
