what is a dual fuel towel rail?

• Dual fuel means you can run the same towel rail in two ways — as electric via the use of a heating element in the summer (when you may only want to dry your towels or clothes) and as central heating in the winter (when the full system is on).
• The water inside the towel rail comes from your central heating system as normal — when the main system is off this water will sit idle, and in the summer the element installed in the towel rail will warm the water located inside just this towel rail. You can keep both of the valves open.

the specialist dual fuel valve

• This specialist dual fuel valve is the best valve to for a dual fuel towel rail as the flow/return is located on the same side of the radiator — leaving the opposing side free for the heating element (so no T-Piece is required, unlike a standard dual fuel set-up).
• The flow and return travel through the valve via the immersion tube: flow goes up the tube and the return comes back down the outside of the tube.
• Angled orientation.
• Choose left or right side as you need for your specific installation - see the image which shows both orientations show side by side to see which suits your room setup and pipework setup best.
