Towel wall heating with heat pump with low return temperature (30 °C)

I don't necessarily want to. I just think it's a nice extra and wanted to ask whether it is even worthwhile with a heat pump heating concept with low flow temperature. But I don't understand why the electric heating is recommended. I thought every electric heating should be avoided – I must have been mistaken.

But I don't really need warm towels necessarily. I thought you could support the underfloor heating a bit and thus avoid a possibly additional wall heating in the bathroom, since it is after all another "pipe" for the bathroom?

Radiators with an electric heating cartridge that automatically shut off after a certain period of time. They come in different versions. Either with a timer or a button and automatic shut-off, etc.

It should become a sensible combination.

It may well be that a local direct electric heating is far more economical than "just another pipe for the bathroom."

It is not just a pipe. If it is supposed to work. There is a lot more connected to it, and in total, that is no longer so attractive.

You do not mix underfloor heating and radiators for two reasons.

Radiators are made of metal and always bring dirt into the circuit of an underfloor heating system, which you do not want.
Radiators require a higher flow temperature to have an effect, which is counterproductive to the concept of underfloor heating that requires low flow temperatures.

If you just want warm towels, then take the towel rail with an electric cartridge. As long as it does not run permanently at the highest level, the consumption is not noticeable.

If you need more heating power in the bathroom, then either an additional wall heating or an infrared mirror to temporarily increase the temperature.

Although I personally doubt that most people really notice a big difference between 20 and 24 degrees in the bathroom.

At the latest when the shower is running, it is humid and warm anyway.

Thank you, that is exactly the answer I was missing. I didn’t know that and now I do.

And since we don’t need warm towels, it will probably be a dry towel rail (also without E-bar).

Whereas I personally doubt that most people actually noticeably feel a difference between 20 and 24 degrees in the bathroom.

That is a claim that I don’t think can be left as is. Just ask your wife.
Mine notices every half degree in the house when I’ve adjusted something on the heating, and in the bathroom I clearly notice whether it’s 21 or 23°.

Simply leaving out a heated radiator generally causes insufficient heat generation in the bathroom due to the size of the space. To then reach the comfortable temperature, the flow temperature must be increased, which in turn is inefficient.
Accordingly, more heated surface (e.g. wall) should be created or the already mentioned alternatives.
