Boiler FAQs
What are the most common boiler problems?
The issues we see most often in Louisville: (1) low pressure — the gauge drops below ~12 psi, often from a micro-leak or a failing expansion tank, (2) no heat but hot water works (or vice versa) — commonly a diverter valve or zone valve on a combi boiler, (3) kettling — a banging/rumbling noise caused by limescale or sludge in the heat exchanger, (4) pilot/ignition lockout — a failed ignitor, flame rectification or blocked condensate trap on high-efficiency models, (5) circulator pump failure, (6) leaking relief valve from overpressure.
What’s the difference between a combi, system and conventional boiler?
Combi (combination) boilers produce both hot water and heat from a single unit with no hot-water storage tank — compact, efficient for small-to-medium homes, but limited by flow rate at multiple simultaneous taps. System boilers feed a separate hot-water storage cylinder — better for multi-bathroom homes, but need floor space for the tank. Conventional (heat-only/regular) boilers use both a hot-water cylinder and a separate cold feed/expansion tank — still common in older homes with radiator networks, and the most tolerant of low incoming water pressure. Choice depends on your household demand, available space, and whether you already have a tank.
Why is my boiler making a banging or whistling noise?
Banging (“kettling”) is usually limescale or sludge buildup in the heat exchanger, causing water to boil in pockets — it often responds to a professional power-flush and inhibitor dose. Whistling can be air trapped in the system (bleed the radiators) or a restriction in the circulator pump. Gurgling points to air or low pressure. A loud “water-hammer” knock on shutdown is often a failing check valve or a pump running the wrong direction. Any of these should be diagnosed before the exchanger is damaged — a new heat exchanger is one of the most expensive parts in the system.
How long does a boiler last?
Residential gas boilers typically last 15–20 years; cast-iron conventional boilers with good water treatment can run 25–30+ years, while modern high-efficiency condensing combi boilers average 10–15 years because the stainless-steel heat exchanger is harder to replace. Hard water dramatically shortens life — mineral scale acts as insulation, overheating the exchanger. Annual service (combustion analysis, flushing if needed, checking the expansion tank and anode) is the single biggest factor in longevity.
