Alpha Cd Expansion Vessel 1.023560

A boiler that constantly loses pressure is a common and frustrating problem. This genuine Alpha CD Expansion Vessel (1.023560) is the vital component required to solve pressure-related issues and restore stability to the heating system. It’s the professional’s choice for a reliable, long-lasting repair for a wide range of Alpha boilers.

The Unsung Hero of Your Central Heating System

The expansion vessel plays a critical, behind-the-scenes role in any sealed central heating system. As water heats up, it expands, significantly increasing pressure. The expansion vessel's job is to absorb this extra pressure safely. Inside this small tank, a diaphragm separates the system water from a cushion of pressurised air, keeping the overall system pressure stable. Over time, these vessels can fail; the diaphragm can split, or the air charge can be lost.

When this happens, the symptoms are unmistakable.

The boiler pressure constantly drops, requiring frequent top-ups with the filling loop. You might also see the pressure gauge shoot up when the heating is on, often causing the pressure relief valve to drip water outside. This isn't just an annoyance; these fluctuations put stress on the entire system. This genuine Alpha Cd Expansion Vessel 1 023560 is designed to fix these problems permanently. Using an authentic part ensures the pre-charge pressure is correct for the boiler and that the materials are robust enough for years of service. It’s the same commitment to quality found in other essential heating components from brands like Altecnic or high-performance pumps from Grundfos. This is a crucial sealed system expansion vessel.
