General information

My Arbonia radiator...

 

Can I buy the radiator I want directly from Arbonia?

No. As an end customer you can obtain our products exclusively from our qualified specialist installers who will be happy to give you a quote. Direct purchase from the factory is not possible!

Who can help me if my radiator isn't working properly?

Pay attention to our advice in the operating instructions. If it is not working after testing the functions described, please get in touch with your specialist installer in order to arrange further measures.

All about the radiator's appearance...

 

How should I look after my radiator?

We recommend that you clean your radiator using a damp cloth. Do not use any strong cleaning products or chemicals, as these substances can damage the surface! For this purpose, Arbonia has introduced several cleaning utensils into their accessories range.

In which colours are the radiators available ?

Arbonia radiators are available in all the colours you can imagine. RAL, NCS and our colour trends "New Inspirations" are just as obtainable as every other colour you may wish for. Please see our colour chart for examples or contact us!

Electric operation

All about electric operated radiators...

Which Arbonia radiators can also be operated using electricity?

All products, except for Entreetherm and convectors can also be run on electricity, taking into account the minimum dimensions. Please ask our technical advisor for support in choosing the correct radiator and heating insert.

Why does my electric radiator only get partly warm?

In order to allow the heating fluid to expand upon warming, the radiator is not filled to the top with heat transfer fluid. Air collects in the top elements, so it is completely normal for the upper area not to get quite so warm. The electric radiator works under the action of gravity. For this reason, the surface temperature of the radiator gradually gets cooler from the top to the bottom. Right at the bottom it stays cold. The radiator and the performance of the electric heater are accurately calibrated, thus guaranteeing the heat output.

Are there any Arbonia radiators that can work with electricity as well as via the central heating system?

Yes. Arbonia offers many models with so-called mixed operation models.

What protection class do Arbonia heaters have?

Protection class IPX4 (water spray)

Technology

All about radiator function...

How do I recognise frost damage?

Everyone knows what happens when you put a full bottle of water in the freezer. The same thing happens in a heating system. Water expands when frozen. However, as it has no room to expand in a radiator that is full to the brim, great pressure builds up. This pressure can reach more than 50 bar. When typical frost damage occurs, the radiator is irregularly deformed. Mostly in the top and/or bottom water pipe. Furthermore, in most cases, cracks can appear in the coating and a lentil-shaped blistering of the coating occurs over the welding points. Leaks are also not uncommon after thawing.

How do I avoid frost damage?

The basic rule is: Never completely switch off the heating during the heating period! This also applies to long periods of absence. Modern heating controls have settings for frost control or reduced operation mode. The thermostatic valves on your radiator should never be fully closed in winter either. Like the heating controls, they also have a frost protection setting. Further details are provided in the operating instructions of your heating system

Where are the noises in my heating system coming from?

Noises in heating systems can have numerous causes. We can differentiate between noises in the radiator itself and those which, for example, are transmitted by the pipes and then amplified in the radiator. Noises arising from the heating system only occur when in operating mode. If these noises also occur outside of the heating period, it can be assumed that, for example, knocks to the radiator or pipes are to blame. When in operating mode, the radiators themselves are very rarely the source of the noise. A 1m long radiator expands by about 0.5mm with a 50ÂșC temperature change. Even if sound-dampening brackets are not fitted, this is not enough to produce noises.

  • Ticktacking (mostly shortly before the valve closes): Generally points to inverted flow and return.
  • Hissing or whistling: Differential pressure too high due to an excessively large pump or pump stage, no hydraulic balance.
  • Gurgling: Air in the radiator.
  • Ticking: Tension in the pipes, tight thermostatic valve.
