Product Information

Alpha 3.013389 Seal Kit- Dhw Diaphragm Cd24s (lpg), Great deals on Alpha spares from Boiler Parts.
The Alpha Cd24s (Lpg) combination boilers and water heaters use a rubber diaphragm to trigger the domestic hot water by diverting the primary water circuit to the plate heat exchanger. This gives hot water to the taps or perhaps shower. One side of the diaphragm is subject to indirect heat via the hot water in the primary circuit flowing through the hydraulic assembly. This design is common in combination boilers and other water central heating appliances. In case a diaphragm has failed the boiler it will not switch easily between delivering water to the hot taps and providing central heating. In this instance it will need exchanging. Many heating engineers will recommend exchanging the entire hydraulic section assembly. This isn't necessary as the boiler manufacturer more often than not supply the specific part and the unit will function properly after the diaphragm is replaced., Alpha Diaphragms Are Dispatched Same Day, For Next Day Delivery
