Boilers use fuel to warm water and circulate the liquid through pipes, heating indoor air. Once the water cools, it’s returned for reheating. These appliances typically last 15 years or longer and require annual maintenance and inspection to operate at its best efficiency. Here are a few signs that indicate it’s time for boiler repairs.

How to Tell If Your Boiler Is Breaking

1. Strange Noises

Clunking and banging noises, also referred to as kettling, may be the result of mineral deposit buildups. These deposits block the water flow to the heat exchanger, causing it to evaporate in the pipe. Evaporating hot water puts pressure on the appliance, forcing it to expand dangerously. This hazard requires professional attention, and the boiler repair technician can safely diagnose the issue and replace parts as necessary.

2. Unusual Smells

The boiler may have a fuel leak if you notice a metallic or eggy smell. The leak can be caused by a lack of maintenance or a poorly fitted fuel hose by the appliance or the seal between the hose and boiler. Since fuel is flammable and detrimental to your health, always call a professional for help instead of trying to address the issue on your own.

3. Water Leaks

If there’s a leak in the boiler, water may pool under it or drip from it. Leaks are the result of corroded pipes. When ignored, corrosion can spread throughout the boiler’s system and cause the need for a premature replacement.

If there’s a leak near the pressure valve, the pressure may be too high, and the valve is leaking to prevent damage to other components. The valve should be in the green section—if it’s red, call for boiler repairs and have a technician check for obstructions in the system.
