Safety first
Boiler parts involve gas, pressure and electrical safety. Please don't attempt DIY repairs — a licensed technician must diagnose and replace boiler components. These pages explain what each part does and the signs it may be failing.
Boiler Gas ValveThe gas valve controls the flow of gas to the burner. It is a safety-critical, gas-carrying component regulated under BC's Safety Standards Act.Learn more Boiler Circulator PumpThe circulator pump moves hot water from the boiler through your radiators, baseboards or in-floor loops so heat reaches every room.Learn more Boiler Expansion TankThe expansion tank (vessel) absorbs the increase in water volume as the system heats, keeping pressure stable and protecting the boiler.Learn more Boiler Zone ValveZone valves direct hot water to different heating zones so each area of your home can be controlled independently.Learn more Boiler Pressure Relief ValveThe pressure relief valve (PRV) is a safety device that releases water if system pressure climbs too high, protecting your boiler and home.Learn more Boiler IgnitorThe ignitor lights the burner each time the boiler fires. It is part of the gas-combustion system.Learn more Boiler Flame SensorThe flame sensor confirms the burner has lit. If it can't 'see' the flame, the boiler shuts the gas off as a safety measure.Learn more Boiler Control Board (PCB)The control board (PCB) is the boiler's electronic brain, managing ignition, sensors, the pump and safety controls.Learn more Boiler AquastatThe aquastat controls the boiler's water temperature and high-limit safety cut-out, common on cast-iron and conventional boilers.Learn more Heating ThermostatThe thermostat tells the boiler when to heat. A faulty or miswired thermostat can mimic a boiler fault.Learn more Boiler Heat ExchangerThe heat exchanger transfers heat from the burner to your water. It is the boiler's most important — and most expensive — component.Learn more Combi Diverter ValveOn a combi boiler, the diverter valve switches the unit between central heating and on-demand hot water.Learn more Boiler Pump SealsPump seals keep water inside the circulator pump body. Over time they wear and can weep water.Learn more Boiler Auto Air VentThe automatic air vent releases trapped air from the boiler so the system circulates properly.Learn more Older & Discontinued Boiler PartsOlder and discontinued boilers can still be repairable when the right parts are sourced — but some parts become hard to find over time.Learn more
