Hydronic towel warmers no longer have a place in new buildings either.

Why?

...The commonly installed underfloor heating system is a low-temperature system (for energy efficiency), which is not compatible with the water-based towel radiator. This radiator usually requires a significantly higher flow temperature.

Is that why there are two heating circuits?

Having 50°C (122°F) at your feet and 40°C (104°F) in the room is just not for everyone.

That's how it is with us (still oil heating).

The energy source would first need to provide a high temperature, which is then artificially reduced for the underfloor heating --> efficiency goes down the drain 😉
