โWhen you look at a cross-section of a modern boiler plate heat exchange, it's easy to see how blockages can occur when a heating system isn't properly maintainedโ
Some typical symptoms you can expect to see:
โ
Reduced hot water flow or weaker tap/shower pressure
โ
Slower hot water recovery (takes longer to reach set temperature)
โ
Fluctuating hot water temperature (surges between hot and lukewarm)
โ
Lower boiler efficiency / higher energy use for same output
โ
Frequent burner cycling or longer run times to reach temperature
โ
Unusual noises (gurgling or reduced flow-related sounds) during hot-water demand
โ
Increased boiler pressure variation when drawing hot water
โ
Error/fault codes related to flow, temperature sensors, or low heat transfer (model-dependent)
If you're having issues like this with your boiler, get in touch today to arrange for one of our gas safe engineers to investigate.
