Two items which belong together:
Heat pump + solar.
Low expenditure – High yield.
At its peak, 80% of solar energy can be converted into usable heat. The extremely high efficiency of ROTEX flat solar panels makes this possible. Solar energy and heat pumps complement each other ideally in this application. The heat pump adds the required amount of heat to the heating system to meet the demand.
A measure of the situation: The annual work index.
It describes how many more times you are gaining on heat energy over the year with respect to the auxiliary energy expended. The higher the annual work index, the higher the efficiency of the heat pump. In connection with our solar plant, the ROTEX heat pump reaches an annual work index of up to 4.3. This means that you get 4 times more heat energy for heating and hot water than the auxiliary energy you are using. The ROTEX HPSU sets completely new standards in the field of air-to-water heat pumps.
Solar energy in stock. The ROTEX thermal store.
ROTEX Solaris uses solar energy for hot water generation and effectively supports heating. In the HPSU compact with 500 litre storage capacity, solar heating support is integrated and ready to connect, alongside the solar hot water generation. If the solar heat is not consumed immediately, the ROTEX thermal store can store large volumes of solar heat. The heat for hot water or heating can be used even more than a day later.

ROTEX Solaris: Use the energy of the
sun and save costs.
The graphic shows when and how much the ROTEX solar system supports the heating and hot water generation. Combined with a ROTEX heat pump, which also exploits regenerative ambient energy, the use of ancillary energy reduces to an absolute minimum.
