ᐅ Is an additional heater recommended in a bathroom with underfloor heating?

Hello everyone,
We are currently planning our new house and have reached the point where we need to decide on an additional fast heating option for our bathroom, one that responds more quickly than the rather slow underfloor heating.
We are considering either a wall-mounted fan heater or an electric towel warmer. We understand that both options have their advantages and disadvantages, but this supplementary heater will only be used during transitional seasons when the underfloor heating is not yet running or has already been turned off.
The bathroom has a floor area of about 18 square meters (living area around 16 square meters (172 square feet) due to the sloping ceiling). The built-in heating system will be an air-to-water heat pump with a controlled ventilation system.
Personally, I’m leaning toward the towel warmer, mostly for aesthetic reasons.
What would you recommend?
Best regards,
Dirk

We also installed a towel radiator. It’s clear that at the maximum supply temperature of 35°C (95°F) from the underfloor heating, it won’t get very warm. For this reason, we added an electric heating element to warm the radiator. It is installed right next to the washbasin and will provide a “heat boost” when desired. This will usually be needed during the transitional seasons.
Warming towels is just a side benefit.

We have an electric towel radiator (with heating cartridge) as a supplementary heating source to our low-temperature underfloor heating system. We connected a timer and set it so that the towel radiator turns on every morning one hour before waking up. Every winter morning, it is nicely warm.

Yes, a gas heating system has a higher supply temperature – and a wood gasification boiler can certainly function as a supplementary heater. It just needs to be properly sized.I am admittedly not a plumbing expert – however, for underfloor heating, it generally does not matter whether the water is heated by gas or a heat pump. So how do you conclude that a gas heating system would require a higher supply temperature when used with underfloor heating?Regards, Bauexperte

With a heat pump, it is very inefficient to size the heating system based on the bathroom requirements.
