Dual Fuel Matt Black T-Piece Connector for Towel Rails (1/2" BSP)

The Dual Fuel Matt Black T-Piece Connector is a high-performance brass plumbing fitting that enables a towel rail radiator to operate on both central heating (hydronic systems) and an independent electric heating element at the same time.

Designed for modern UK and European bathroom heating systems, this T-piece allows seamless dual-energy operation through a single 1/2" BSP bottom inlet. Engineered to pair flawlessly with our premium matt black towel radiators, it is the essential component for converting a standard towel radiator into a flexible dual fuel towel rail system, giving you year-round heating control. Use your central heating in winter, and switch to electric-only operation in summer when your boiler is turned off.

What Is a Dual Fuel T-Piece Connector?

A dual fuel T-piece connector is a specialist plumbing fitting used in towel rail systems. It allows both a central heating valve and an electric heating element to connect to the same radiator inlet. This creates a hybrid heating system where your towel rail can operate via boiler-powered central heating in winter and switch to electric heating in summer.

---

How It Works

The T-piece is installed at the bottom inlet of the towel rail radiator. It divides the connection into two separate pathways:

• One port connects to the electric heating element
• The side port connects to the radiator valve / return pipe

This enables safe dual-energy operation from a single radiator entry point.

Installation Guide (Step-by-Step)

Always ensure the heating system is turned off and depressurised before installation.

1. Screw the T-piece connector into the bottom inlet of the towel rail
2. Apply PTFE sealing tape to all threaded connections for leak prevention
3. Insert the electric heating element vertically into the designated port
4. Connect the radiator valve to the side outlet of the T-piece
5. Tighten all fittings securely and check alignment
6. Test the system for leaks before full operation

Installation Tip: No external O-ring is included. Use PTFE tape on all threaded joints to ensure a watertight seal.
