Questions and answers: Technology

How big must my radiator be? How can I calculate the required heat output?

When calculating the heat output, there are many factors that need to be considered. We do not advise an estimated calculation. We recommend calculation by a specialist dealer.Back to top

What does flow balancing mean?

Flow balancing is the limiting of the water volume flows to values that correspond to the heat requirement of the plant. By means of a 'hydraulic regulation', which generates the same resistances for all the radiators in a heat distribution network, flow noises, overheated rooms and rooms with a shortfall of heat supply are avoided. In addition, the energy consumption for heat generation and heat distribution are optimized. Your specialist dealer is the correct contact person for a radiator that works at a comfortable and economical level. Back to top

How can I deaerate my radiator?

To deaerate a radiator yourself, some technical skill is required. Either have the deaeration done by a technician or get detailed information in advance.Back to top

My radiator is making knocking sounds. What does that mean?

One frequent cause of 'knocking sounds' at the thermostat valve is interchanging of the flow and return. As a result, the flow in the valve is in the wrong direction. Please contact your technical specialist.Back to top

My radiator does not reach the required temperature. Why?

There could be several reasons for this: Is the setting of the thermostat sensor correct? Is the radiator correctly deaerated? Is the flow temperature sufficient? Is the circulation pump working correctly? Has the heating plant been flow balanced? Please contact your specialist dealer.Back to top

My radiator makes flowing sounds. Why?

There are sounds that could be heard as rushing sounds constantly over an extended period of time. These are generally flowing noises. Generally, these are due to excessively high flow rates (because of excessively high differential pressures) in certain sections of the heat distribution, for example in valves. Flow balancing (see the notice "Flow balancing") by a specialist dealer can help.Back to top
