Working Principle of the System

In contrast to conventional radiators having a heating surface that water flows through, this innovative radiator only needs a single perfused pipe to heat up the entire heating surface.

For a radiator sized 600 x 1000 mm, this corresponds to a pipe 1 m in length that contains approximately 0.175 liters of water. A comparable standard radiator needs 20-fold in water.

Heating of the heating surface of the radiator is provided by non-hazardous heat transfer fluid.

Essentially, the innovative composition of the heating fluid provides a unique and highly efficient heat transfer.

Less Energy Consumption


Shorter Heat-Up Time


Reduced Water Volume

The heat generated in the tube register is output via fins of aluminum as energy is radiated outward to heat the room.

A performance comparison test carried out by an independent certified institute showed that the CaloEnergia radiators only require 42% of the thermal work and only 36% of the hot water passing through for the same heat generation in comparison to a conventional radiator.

The diagram shows the structure and operating principle of the CaloEnergia radiator. The heating fluid of water causes a small temperature loss. The temperature difference between the supply and return ports is typically between 1-4 ° C.


At a flow temperature of 60 ° C, a heating temperature of about 56 ° C is reached. This incredible efficiency and extremely rapid heat transfer is illustrated by the following experiment:
