Electric bathroom heater vs. classic bathroom heater

Hello everyone,
in my current apartment we have a small problem. We usually don’t heat the entire 130 m² (especially not at night), but only where we stay.
However, this also means that our towels in the unheated bathroom dry very poorly and quickly start to smell musty.

We usually shower in the evening and do not heat at night.

One option would be to heat the bathroom at night just to dry the towels. The towels hang 3m away from the radiator on the wall, so the room would have to be heated quite well for a long time to dry the towels.

A second option would be to install a second radiator. The connection would then have to be done by the landlord (or their plumbing service provider) and a heat meter from ista would have to be installed. So there are quite significant additional costs.

The third option would be an electric bathroom radiator, which would only be turned on in the evening to dry the towels.

Actually, option 3 seems to be the easiest option and intuitively the most efficient. But I would be interested in how efficiently it really heats. The model would be approx. 1600 * 700 mm with 900 W. If the heater would have to run for 10 minutes to then generate enough heat to dry the towels, then that could be cheaper/more efficient than heating the whole room with district heating.
But if the heater has to run for an hour or even longer and thus consumes > 1kWh per day just for drying towels, then it might become questionable again.

Does anyone here have experience with electric radiators or even directly with our little problem?

Thank you very much for your opinions

With an infrared panel and arm for the towel, the towels dry very quickly. I wouldn’t expect it to take more than 20 minutes. Do you have some space in the bathroom and enjoy design? Then take a look at Tubes Scaletta. It warms the towel, lets air through = good drying, and doesn’t need quite as much energy. From an energy perspective, drying towels with a heater is basically quite a mess.

And from an energy perspective, one should not keep any rooms in an occupied apartment completely without heating at all times.

Thank you for your answers.

And from an energy perspective, you shouldn’t keep rooms in an occupied apartment completely without heating all the time.

The problem is that the apartment is only "used" on weekdays from about 6:00 p.m. to 6:30 a.m. Therefore, it makes more sense to only heat the living and dining rooms in the evening and the bedroom at night during the week.
Although I haven’t actually measured this yet. But I would suspect so.
The apartment doesn’t get colder than 17 °C. About 30–50 m² are not used at all during the week and only a little on weekends (office, children’s room [since there is no child yet it is currently a wardrobe], bathroom, hallway). Somehow, I can’t imagine that it’s cheaper to keep all that heated to 20 °C around the clock than to let it cool down and heat it up as needed.

But please correct me if I’m wrong! :)

From an energy perspective, drying towels with heating is fundamentally quite a mess, of course.

We have space on the wall, but not freestanding, and actually we like things to be stylish, but above a certain purchase price it doesn’t make sense anymore (for 1000 € you can heat the bathroom for quite a long time :D).

but beyond a certain purchase price it no longer makes sense

A purchase that brings long-lasting joy is worthwhile. That is my attitude towards design. The radiator you mentioned (remove the link again, otherwise there will be trouble with the webmasters) includes an electrically operated heating cartridge integrated into a heat-storing system. When you turn off the heating, it stays warm for a while. However, the warm-up phase takes time. In that case, I would possibly go for infrared – turns on immediately, turns off almost immediately – and is therefore easier to use.

No, 20° is not necessary, but 15 to 17° should be maintained. Normally, normal radiators are set to level 1 to 2 or so for this purpose. Once the corresponding temperature is reached, they stop heating and do not consume energy.
