Is an additional heater recommended in the bathroom with underfloor heating?

That's exactly right. It says so in the questions and answers on Amazon. And if you take a look on Ebay, you can also find a picture showing that the heating rod is horizontal at the top.

I'm digging up the post again.

We have decided against a towel radiator at short notice.

Above the area between the shower and the sink, I am planning a ceiling infrared heater with 450W.

Can you notice anything when the heater is on the ceiling?

It is actually intended only for the transitional period to make it a bit more comfortable, not to increase the room temperature.

So far, the infrared heaters have been viewed so negatively here - I would like to add my opinion on that:

I lived for a while in an apartment with a heater and thought it was great. It's a feeling like stepping out of an outdoor pool in the sunshine while wet. It got to the point where I hardly turned on the bathroom heating (at least not heated above normal room temperature).

I understand that not everyone finds that pleasant (I'm not so sensitive - everything between 16 and 20 degrees in the apartment is comfortable for me). But it's only about some additional warmth. The bathroom already has a base heat of 22 to 24 degrees. At least the underfloor heating should achieve that, otherwise something is wrong. But turning on the unit to dry off after the shower feels good and doesn't cost the world, since the thing heats up immediately and therefore only runs for five minutes.

However, the installation should maybe not be on the ceiling but rather on a wall/ceiling corner, so that not only the fur and shoulders get hot!

I'm bumping this topic because I'm very interested in it right now. We don't have a towel radiator yet, but the cooler season is coming, and now it's really time for one. We have our eye on panel-style towel radiators (I don't like pipes because of the dust). This one is 184cm x 48cm and can only be operated with a 600-watt heating element, which is inserted horizontally at the TOP. Is 600 watts enough for a bathroom of about 11m2? What is the difference between 600 watts and 1000 watts? Does that mean the water in the radiator won't get as hot, or does it mean it just takes longer?

Have you actually installed the heating element at the top, and does it have to be that way? I only know it being installed at the bottom; then the heated water rises, creating circulation. Otherwise, if you heat the water at the top, it will be happy and stay at the top while the towel radiator stays cold at the bottom???

Did you actually install the heating element at the top, and does it have to be that way?

No, we chose a different radiator exactly because the heating element is at the bottom.

Nice post that I would like to build on.

What are the experiences with infrared heaters? Has anyone implemented this in their bathroom?

Would an infrared mirror be similarly suitable as a ceiling infrared heater?
