New bangs, kettling, whistling or gurgling from your Rinnai combi? Here’s what the sounds usually mean. CANRO Heating & Cooling has serviced residential boilers across Greater Vancouver since 1999. Call (604) 359-1081 or book a licensed boiler technician.
A healthy combi runs fairly quietly. Banging or “kettling,” whistling, gurgling or knocking usually points to scale, air or flow issues — rarely an immediate danger, but worth fixing before it stresses the boiler.

📞 (604) 359-1081Book boiler serviceNote when the noise happens (start-up, full heat, hot-water use) and the pressure reading to help us diagnose. Descaling, bleeding and pump work are technician tasks on a sealed gas combi.
A residential boiler combines gas (or oil), high-temperature water under pressure, electrical controls and sealed combustion. Work on any of those by an untrained hand is genuinely dangerous — gas leaks, carbon monoxide, scalding and electrical shock are all real risks. In BC, gas and boiler work must be done by a TSBC-licensed technician, and doing it yourself can void your warranty and your insurance. A CANRO technician diagnoses your Rinnai combi boiler properly, repairs it to code, and confirms it is safe before leaving. If a part is unsafe or worn, we tell you honestly.
CANRO serves residential boiler customers across Metro Vancouver — Vancouver, Burnaby, Richmond, New Westminster, North Vancouver, West Vancouver, Coquitlam, Port Coquitlam, Port Moody, Surrey, Delta, Langley, White Rock, Maple Ridge, Abbotsford and Chilliwack. Local, TSBC-licensed technicians who know BC homes, BC gas code and BC rebate programs.
Usually scale on the heat exchanger overheating water. A descale/flush typically fixes it — left alone it stresses the boiler.
Usually a performance/longevity issue rather than a hazard. But if noise comes with a gas smell or repeated lockouts, treat it as urgent.
Often — descaling and bleeding resolve most scale- and air-related noises. Book an annual service.
