Bathroom radiator Duolino in a modern bathroom

Duolino radiators are characterised by a high heat output, practical dimensions, timeless design and an outstanding price/performance ratio. The bathroom radiator is particularly suited to low temperature applications and, as well as heating the room, provides a place for elegantly warming hand towels, bath towels and the like. The modern design meets high architectural requirements.

The radiator is connected to the hot water central heating and can also be operated with an electrical heating insert as an option or can be all-electric. The vertical, trapezoidal manifold pipes and the dual, parallel transverse pipes are characteristic of the design.
