ESBE's VMD300 series solar heating kit offers two functions for drinking water installations: when the supply water needs to be heated, it switches it to the boiler and prevents scalding due to too high leaving water temperature. Both functions are provided by the easy-to-install solar heating kit. This series of devices allows full adjustment of the switching temperature for optimisation
system for the use of solar energy.

ESBE's compact and powerful VMD300 series solar heating kit ensures optimal performance
energy efficiency, burn protection and comfort. Thanks to the use of only thermostatic
components (not electrically powered), the kit is fully self-contained and very easy to install.
This series of devices allows you to adjust the switching temperature in the range from 40 to 52 degrees, which gives you the opportunity
minimizing the consumption of energy obtained from an additional heat source (e.g. gas boiler).
To further reduce (or limit) energy losses in the system, the device is equipped with thermal insulation.

If the supply water from the solar collector does not have a sufficient temperature, it is switched to additional
source of heat (e.g. gas boiler) and after heating it is stirred in order to reach the temperature suitable for it
domestic hot water. If the supply water from solar collectors has a sufficiently high temperature, then
the additional heat source is omitted and the mixing process is designed to produce water at the desired temperature.
By optimizing the use of solar energy, the energy costs incurred for the preparation of domestic hot water are reduced
