ᐅ Are towel warmers mandatory?

Hi,

I have already read a few threads, but I still have a question.
We are getting a guest toilet in our new home, and we are adding a shower to it. The guest toilet will have about 3 square meters (32 square feet) of floor space and will have underfloor heating (like all rooms). According to the construction company, because of the shower, we now have to install a towel radiator. I assume this is related to the heat demand calculation. But is that really the case? Can they require this, or can I insist that the underfloor heating in the small bathroom is just laid more densely? It is also not yet decided whether the radiator will be electric or connected to the underfloor heating system. The latter doesn’t seem to make much sense either.

Best regards
Sebastian

I currently have 21°C (70°F) in the office with an outside temperature of about 0°C (32°F), and the flow temperature is set to 24°C (75°F). At least we have a mechanical ventilation system with heat recovery that is always running, so we hardly ever ventilate manually. The heating curve works well for all temperatures, keeping it consistently warm, even when it gets colder or warmer outside.

The bathrooms (which is the main topic here) are at the same temperature; even the small guest bathroom with a shower on the ground floor is not colder (but also not warmer, of course). For me, my wife, and the kids, this is sufficient because the air gets warm enough from showering and bathing so you don’t have to feel cold.

We don’t really need a heated towel rail; the towels dry quickly enough (probably due to the mechanical ventilation, since each bathroom has an exhaust vent). Maybe we’ll add an infrared heater when we’re older, but that’s a long way off.

Our planner (from the general contractor) mentioned that the towel radiator will be connected to the underfloor heating system and is currently not electric. This means it will not get warmer than the underfloor heating, so about 30 - 35°C (86 - 95°F)?

We can upgrade the heating with a 600 W electric heating element for around 300,-, but we are not allowed to remove it. In theory, the 24°C (75°F) must be achievable, and for that, an additional towel radiator is necessary.

Hello Tecker

Installing a heating element in a flow-through radiator does not make sense, as the generated heat dissipates immediately.

Just that the heating rarely reaches 30°C (86°F) or even 35°C (95°F) supply temperature (nor should it).
If you insist on leaving out the towel radiator, it can of course be omitted – in that case, I would seriously reconsider the designer.
If you want to have it, that’s also fine – it won’t cause any harm; it just costs money and collects dust.

What do you mean by "it dusts around"? We actually find it practical and quite pleasant when the bath towels are nicely pre-warmed...

@BeHaElJa, what do you mean by rarely having a 30°C (86°F) supply temperature? I guess many have around 30°C (86°F) supply temperature in freezing conditions, without wanting to argue about 1-2 degrees...

As mentioned, it's mostly a matter of personal preference; in our case, it would get dusty because we tend to be a bit careless there. The thing doesn’t cost a fortune anyway.
Possible at -7°C (19°F), but that’s only for about 2-3 weeks per year at most.
