Boiler pumps – FAQs:
What does a boiler pump do?
A boiler pump, also known as a circulator pump or central heating pump, moves hot water from the boiler through the heating system and back. It ensures the heated water flows efficiently to taps, radiators, showerheads, or underfloor heating systems. By maintaining consistent water circulation, the central heating pump helps the system operate efficiently and prevents overheating or pressure build-up.Â
How long do boiler pumps usually last?
The life expectancy of a boiler circulator pump is typically 10+ years. Regular servicing can help extend its lifespan, but over time, wear and tear from factors such as usage, water quality, and maintenance, may lead to needing a circulator pump replacement.
How to check if a boiler pump is faulty?
If your boiler is making unusual sounds like grinding, rattling, or humming, there may be an air lock or blockage preventing the pump from working correctly. Bleeding the system might solve this issue but first you should check that the thermostat is calling for heat and that the circulator pump is receiving power. Some circular pumps have variable speeds, so you may want to check your pump is set to the correct speed for your system too.
What causes a boiler pump to fail?
The main reasons circulator pumps might fail are from wear and tear, overheating from poor water flow or blockages, air locks in the system, corrosion inside the pumps from water quality issues, electrical faults or motor burnout, clogged impellers from debris buildup, or seal failures leading to leaks. Regular maintenance can help prevent many of these problems.Â
