Genuine Baxi 248734 DHW Differential Valve (Performa) – Plain Boxed Part

Ensure your boiler accurately detects domestic hot water demand with the Genuine Baxi 248734 DHW Differential Valve. Specifically engineered for the Baxi Performa boiler range, this vital brass component houses the diaphragm and pin mechanism that senses changes in water pressure when a hot tap is turned on, triggering the boiler to ignite and switch from central heating to hot water mode.

If your boiler fails to fire up for hot water but works perfectly on central heating, a worn or scaled differential valve is often the cause. Replacing it with this brand new, authentic manufacturer spare guarantees a precise fit, leak-free operation, and restores instant hot water responsiveness.

This item is supplied brand new in plain protective packaging. Trust Warwick Heating Supplies to provide genuine, high-quality replacement parts for a safe and lasting repair.
