A dual fuel towel rail works via an included electric heating element as well as the central heating system within a property.
T-piece adaptors are used to achieve this – they enable the user to add a heating element whilst simultaneously plumbing the towel rail into your central heating system.
By contrast with ‘standard’ heated towel rails, dual fuel components can operate in the absence of a central heating system. So, by working via an electricity supply, they can heat up on their own, remote from other heating devices powered by a central heating system.
