Hello everyone,
I currently have a small problem in my apartment. We usually don’t heat the entire 130 m² (1400 sq ft), especially not at night, but only the rooms where we spend time.
However, this means that our towels in the unheated bathroom dry very poorly and quickly start to smell musty.
We usually shower in the evening and don’t heat the bathroom at night.
One option would be to heat the bathroom at night just to dry the towels. The towels hang about 3 m (10 ft) away from the radiator on the wall, so the room would need to be heated well for quite a while to dry the towels properly.
A second option would be to install a second radiator. However, the connection would have to be done by the landlord (or their plumbing contractor), and an energy meter from ista would need to be installed. This would involve significant additional costs.
The third option would be an electric bathroom heater that is only turned on in the evenings to dry the towels.
Option 3 actually seems like the simplest and, at first glance, potentially the most efficient solution. But I’m curious how efficient these actually are. The model would be about 1600 x 700 mm (63 x 28 inches) with 900 W. If the heater would only need to run for 10 minutes to generate enough heat to dry the towels, it could be cheaper/more efficient than heating the entire room via district heating.
But if the heater has to run for an hour or longer, consuming more than 1 kWh per day just for towel drying, it might be less attractive.
Does anyone have experience with electric heaters or maybe even advice on this specific issue?
Thanks a lot for your opinions

AleXSR70015 Nov 2021 18:43Hi,
as mentioned, the apartment rarely gets that cold. A base temperature of over 15°C (59°F) is maintained (possibly by heating).
However, that is not enough to dry towels, unfortunately.
Infrared heaters look interesting but usually have the drawback that they are panel-like, with the wall mounting located awkwardly on the back.
This means you cannot hang a towel over the heater (one half in front and one half behind the panel); instead, the towel must be folded double and hung in front of the panel. This is obviously much less efficient.
In principle, I don’t mind the residual heat. I would try to adjust it to find the best balance between heating duration and drying with minimal residual heat.
The radiator would be connected to a Shelly device anyway, so I can switch it on and off or set timers quite precisely.

RotorMotor15 Nov 2021 18:44Will the bathroom actually dry out properly, or is there a risk of mold developing?
KingJulien15 Nov 2021 18:47Is maximum drying, meaning the transfer of moisture into the indoor air, combined with minimal heating really a good idea?
I would be worried about mold.

AleXSR70015 Nov 2021 18:50So far, there have been no mold issues. However, the door is almost always open, allowing the moist air to spread throughout the apartment, which, given its size, makes the humidity negligible. Ventilation is, of course, sufficient. And right after showering as well, ensuring that the majority of the moist air is exchanged immediately.
Sorry, but this is really difficult to read

No mold issues so far. The door is almost always open, so the moist air spreads throughout the apartment and becomes negligible given the apartment's size.
