My boiler is not constantly supplying hot water

There are several possible reasons why your Potterton Promax HE Store Range boiler may not be supplying hot water consistently:

1. Programmer Settings: Ensure the programmer is set to 'DHW ON' during the required periods. If it's not, the boiler won't operate to heat the water.

2. Scaling in Hard Water Areas: If you live in a hard water area, limescale buildup may be affecting the heat exchanger and reducing hot water performance. A water treatment device, such as an ion-exchange water softener, may be needed.

3. Pressure Issues: If the boiler operates in a sealed primary system, ensure the system pressure is correct. Low pressure can affect performance.

4. Flow Restrictors: Using flow restrictors can help prolong hot water availability, especially in systems with smaller storage capacities.

5. Maintenance: The boiler may require servicing or cleaning if components like the heat exchanger are not functioning properly. Ensure the system has been maintained by a competent person as recommended.

6. Expansion Vessel Sizing: If the expansion vessel in the system is undersized or not operating correctly, it could impact performance.

If these steps do not resolve the issue, consulting a qualified service engineer is recommended.
