Questions and answers
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.
