ᐅ Electric towel warmers or connection to underfloor heating?

Hello,

in addition to the underfloor heating (air-to-water heat pump), we will have a towel radiator installed in the bathroom. As standard, our general contractor also connects it to the underfloor heating system. However, wouldn’t it make more sense to operate it electrically due to the low flow temperature and its dependence on the operation of the main heating system?

What are your thoughts on this?

It doesn’t matter, you don’t need one at all. We also thought about it for a long time and found it completely unnecessary.

Exactly. So, if absolutely necessary, then via E, as cheaply as possible; that will then warm the towel for Mom a little, and that’s fine.

We don’t need one, but we have one in the family bathroom. It’s electric. It’s convenient for hanging towels near the shower. We use it maybe 10 times at most, it’s just a luxury. It wouldn’t get warm on the underfloor heating.

PS Ours is open on one side.

I find them unnecessary as well. I've never felt the need to heat my towel. They also collect dust. I preferred to install a cabinet in that space instead.
If anything, it should be electric. With the supply temperature of underfloor heating, it will hardly get warm.

The heat pump is electric and not water-based.

The supplementary heater is usually needed to quickly raise the temperature occasionally. It can be completely omitted if you add wall and/or ceiling heating surfaces in the bathroom in addition to the underfloor heating. In this case, the bathroom can even be kept slightly warmer than the other rooms permanently.

If you operate the air-to-water heat pump with individual room control, a buffer tank, and a higher/less efficient flow temperature, then you can do without everything – but you probably don’t want that. If you omit the supplementary heater, still plan for the electrical connection. It is possible without it, but careful planning is required, as the bathroom is often the weak point at low flow temperatures. We rarely use ours, except to raise the temperature above 21°C (70°F) briefly when the baby is present.

You can get exact information from a room-by-room heat load calculation and the subsequent planning of the surface heating system—not just an estimate.

If you choose electric heating, infrared is somewhat more comfortable.
