ROTEX thermal stores. Unparalleled hygiene and convenience.
ROTEX thermal stores provide a constant supply of hot water.
The ROTEX thermal store is a combination of hot water storage tank and instantaneous water heater. The domestic water to be heated is conveyed and heated through a separate high-performance heat exchanger made of stainless steel. Water that is charged first is also the first to be removed (first-in first-out principle).
The tank temperature of the ROTEX thermal store can be reduced from 60 °C to 50 °C, according to DIN 1988-200. The amended DIN 1988-200 permits reduction of the tank temperature from 60 °C to 50 °C in central hot water storage tanks with increased water exchange rates (in Germany).
The drinking water is contained in a high-performance heat exchanger made of durable stainless steel (INOX). Your drinking water remains perfectly hygienic.
The storage tank water is added at commissioning and serves only for thermal storage. It is not exchanged and consumed. The inner and outer walls are impact-resistant polypropylene, the space in-between is filled with highly heat insulating foam. This results in very good heat insulation values and minimum surface losses.
Variable in use.
The heating of the storage tank water, and thus the charging of the storage tank, can take place using various different heat sources:
- With heating water: Boilers, heat pumps or remote heat generate the heat that is introduced via the stainless steel heat exchanger.
- With solar energy: E. g. via the ROTEX Solaris system.
- With an electric immersion heater: The hot water (domestic) is heated by an electric immersion heater made of stainless steel which is immersed in the storage tank water.
