ROTEX solar cylinder. Stock up on solar energy.
Store solar energy with solar cylinders.
ROTEX Solaris uses solar energy for water heating and effectively supports heating. In all ROTEX solar thermal stores, and the gas condensing/solar combination (GCU compact) and heat pump/solar combination (HPSU compact) with a storage tank volume of 500 litres, solar heating support has also been integrated ready for connection, alongside the solar hot water generation. If the solar heat is not consumed immediately, the ROTEX solar thermal store can store large volumes of solar heat and it is possible to use the heat for hot water or heating hours later or even the next day.
The perfect thermal store – the right temperature in each layer.
The thermal store on the ROTEX solar thermal store is a doublewall fully plastic structure. The space between the internal and external tank is filled with expanded foam and is extremely heat insulating. On the inside, depending on the design, there are two to four heat exchangers made of stainless steel corrugated pipe. The 300 or 500 litre tank is filled up once with unpressurised tap water without additives. Solar collectors work more efficiently the colder the water is that flows through them. In thermal solar systems it is therefore important that the thermal store has the best possible pronounced temperature stratification behaviour. With the ROTEX solar thermal store, the cold fresh water is fed into the corrugated pipe heat exchanger made of highquality stainless steel, at the lowest point of the thermal store. From here it is directed upwards and heated using the continuous heating principle. This ensures that the temperature in the lowest part of the thermal store from where the solar panels are supplied with water is cooled to the maximum. The temperature stratification generated in the ROTEX solar thermal store increases the overall exploitation of the solar installation.
The Hybrid central unit – open for all energy types.
All ROTEX solar thermal stores can also be used as an efficient thermal store for additional heat sources. For example, in addition to a solar system, a fireplace with water pocket can be used to provide support during heating and hot water generation. If you are not installing a solar system directly, it can retrofitted quickly and easily at any time.
