Differential thermostat

In the old days, we used to heat water to a constant temperature, whether we needed it or not. Today, we realise that wasteful energy use is a cost, so we think about saving. Modern differential thermostats ensure maximum use of the available solar energy and the possibility to set individual heating programmes depending on when the user actually needs the water heated. The Seltron SGC differential thermostat also allows you to store excess energy in a storage tank. The stored energy is later used in the heating system and thus significantly increases its energy-saving performance.
