Dual fuel heated towel rails work through an included electric heating element as well as the central heating system within a property.
The heating element itself can be fitted via a T-piece adaptor, which enables the user to include a heating element whilst the towel rail is plumbed into the central heating system simultaneously.
In contrast with ‘standard’ heated towel rail models, dual fuel components are operational in the absence of a central heating system. Therefore, in working via an electrical supply only where necessary, they can warm up individually, when other components relying on the central heating system could not do if it was switched off.
