ᐅ Converting or disconnecting towel warmers to electric operation

Hello,
after living in our newly built house for some time, I am currently looking into the heating system.
We have, among other things, a towel radiator with a central connection that is also connected to the underfloor heating. I now know that this setup is not ideal.
What has prompted me to take action soon is the fact that the water in the tubes of the radiator manifold is quite yellow to brownish, which I attribute to rust coming from the towel radiator.

The question now is what to do?
Two options come to mind:
- Convert to electric heating if possible. I have a power outlet right next to the towel radiator. Is this possible with any towel radiator? I don’t know which model or manufacturer is installed. Is this something a layperson can manage? I have no knowledge in this area.
So either an electric heating element or a completely new towel radiator.
- Disconnect the towel radiator so it no longer runs through the underfloor heating and becomes just "decorative." What do I need to do for that? Just tighten the connection with pliers?

What do you think?

It’s basically quite simple.

Is the towel radiator completely on its own separate heating circuit? If yes, then close the supply and return valves at the manifold for this circuit.

Disconnect the middle connection. Remove the towel radiator from the wall and turn it around.

Screw in the appropriate cartridge. Pay attention to the torque. Fill with the suitable fluid. Seal the hole with the matching plug.

Check that both are leak-proof.

Reinstall the radiator on the wall. Close and seal the middle connection coming from the wall or floor.

@Pamiko ... unfortunately, the glass balls are currently out of stock 😉 😉 .. you can’t really say anything about the type of your radiator yourself, so it would be helpful if you could take a photo of the connection situation of your radiator. Then someone here will surely be able to give you more useful advice.

The towel radiator and bathroom are connected to the same heating circuit. Here are two pictures. Sorry, I thought the information did not require any images.

You definitely need fittings for the central connection of the towel radiator, or you will need a completely new one.

The pipes coming out of the wall must also be connected together so that a complete loop is formed, as we do not know whether they are arranged in parallel or in series within the bathroom heating circuit.

A towel radiator can also be operated with an additional electric heating element without separating it from the flow and return of the heating circuit.
A timer can then be used to activate the electric element at the desired times.
If you want to separate it specifically because of rusty water, the heating medium must not come into contact with iron anywhere in the entire heating circuit.
This starts with the circulation pump.
