To ensure that a heat pump can reliably generate heat under all weather conditions, ...
... its components must be protected by means of electrical heat tracing.
Heat pumps are used to recover freely available energy from the environment in order to heat spaces or water. As a result, they provide an efficient and environmentally friendly method of heating. The naturally available energy comes from the ground, groundwater, air or the sun.
A heat pump works similarly to a refrigerator, only in reverse: while the refrigerator conducts the heat to the outside, the heat pump draws the energy into the living space via the connected heating system. For this purpose, a refrigerant is vaporised and liquefied several times, so that with each step it releases more heat than it has absorbed. The entire system requires very little electricity for the drive and pump and the user remains less dependent on fossil fuels such as oil or gas. The heat pump therefore also helps to reduce CO2 emissions. It is an ecologically friendly method of generating heat!
However, for the heat pump to be an efficient long-term investment, individual components must be heated to remain functional in all weather conditions.
An eltherm electrical heat tracing system protects the heat pump ...
... from frost and prevents condensation.
To maintain the optimum functionality of a heat pump at all times of the year, the use of electrical heat tracing is necessary.
On the one hand, electrical heat tracing is used on the evaporator to heat the nozzle ring round the axial fan. As the flow causes temperature and pressure point differences in this nozzle, heating is necessary to protect the components from frost. If no heating system is used, ice crystals can form and damage the system in the long run. To prevent this, a heating tape is placed round the nozzle ring.
Secondly, the condensate collection tray of the heat pump's outdoor unit is heated. The condensation water is collected in this tray. In cold weather, however, the condensation would freeze directly in the collection tray and spread upwards, where it could affect the evaporator. To avoid this, the drip tray and the following drain are heated.
For electrical heat tracing on heat pumps, fixed resistance heating cables or self-regulating heating tapes are used. The heating cables are regulated by measurement and control technology that is tailored to the entire system.

FAQ
The heat pump works in a similar way to a refrigerator, but in the opposite way. It uses freely available energy from the environment to bring heat into the living space via the connected heating system. Here, the energy can be used for heating or to produce hot water. The energy that is freely available comes from the ground, groundwater, air or the sun, for example. In this way, the heat pump is used for a sustainable heat generation that also reduces CO2 emissions, as it is less dependent on fossil fuels.
- As temperature and pressure point differences occur on the outdoor unit during operation, ice crystals can form in cold temperatures and deposit on the rotor or the nozzle ring. This impairs their function and damages the heat pump in the long run.
- Any condensation is collected in a drip tray. As it would freeze immediately in cold weather and spread upwards, the collection tray and the drain are heated.
