Boiler Repair questions, answered by experts

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

Schedule annual inspections, check for leaks, and bleed radiators to ensure efficient operation.

Signs of needing a new expansion tank include visible leaks and a dull sound when you knock your knuckles against the tank (working tanks should sound hollow). A malfunctioning tank may also sweat with condensation, cause pipes to create loud noises when the system is turned off, and lead to very high-pressure readings on the boiler’s gauges. When in doubt, call for a professional inspection to find the source of the problem.

Addressing banging, clanging, and hissing radiators involves several steps. Start by bleeding the radiator to release trapped air, a common source of noise. Next, ensure all valves, brackets, and pipes are securely tightened to prevent the components from rattling. You can also consider installing radiator insulation to dampen heat expansion sounds. If you perform all of these fixes and the noise persists, explore the use of radiator additives that can mitigate water-related noises. If all else fails, you should consult an HVAC professional.
