An inexhaustible source of heat right on your doorstep

The sun is our natural supplier of energy. Make use of this free heat supply for your house.

If you use ambient energy from the air and sunlight to heat your home, then this heat supply is free of charge and, at the same time, inexhaustible.

Two that belong together: Heat pump + Solar energy

Little effort – great benefits

At its peak, 80 % of solar energy can be converted into usable heat. The fantastically high degree of efficacy of the ROTEX flat solar panels is what makes this possible.

Solar energy and heat pump complement each other here in an ideal way.
Depending on need, the heat pump feeds the necessary quantity of heat into the heating system.

The measure of things: The annual seasonal coefficient of performance

It describes how many times more throughout the year you obtain heat energy relative to the auxiliary energy used.

The higher the efficiency rating, the greater the efficiency of the heat pump.
In connection with our solar plant, the ROTEX heat pump reaches an annual seasonal coefficient of performance of up to 4. 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 area of air/water heat pumps.

Practically unbeatable: Heat pump + Solar energy!

In the case shown the energy proportions are divided up as follows:

Solar energy approx.: 20%
Heat pump approx. 55%
Auxiliary energy approx. 25%





yellow: Solar energy/ green: Heat Pump/ blue: Auxiliary energy

The annual seasonal coefficient of performance according to this example is therefore: SCOP = 4.0 (SCOP = Seasonal Coefficient of Performance)

Direct use of solar energy simply included

The ROTEX HybridCube® heat storage tank is already ideally equipped for using solar energy.
If you only want to decide to acquire a solar plant later on, then it is quick and easy to install it at a later date.
