.A sudden lack of heat in the home should never be ignored, especially during the winter months. In homes that utilize radiant heat, this often indicates a broken or damaged boiler that may require repair or a full replacement. In many cases, full boiler replacements can be avoided if the issue is caught in time. Prior to completely failing, radiant heating systems often give off warning signs that indicate the boiler may be in jeopardy. Understanding the telltale signs of a failing boiler can help homeowners quickly detect potential issues, allowing for immediate boiler repair and a safe, warm home. 

Strange Noises

A properly-running boiler should not emit any noise, as the units are designed to run quietly. Banging or clunking sounds, commonly referred to as "kettling noises," usually indicate a build-up of deposits inside the heat exchanging unit. Over time, the buildup can hinder the water flow, which can lead to internal damage if left untreated.

Whistling noises typically indicate a build-up of air in the boiler. Hissing noises can indicate an overheating boiler. It is always best for homeowners to contact a professional boiler repair technician at the first sign of an unusual noise, even if the heater appears to be working normally. 

Water Leaks

A pool of water surrounding the boiler can indicate rusty or corroded pipes, damaged valves or issues with the tank itself. If scaling or rust is detected on the boiler's discharge pipes, this is a telltale sign that the pipes are definitely leaking water. Water leaks should always be inspected by a professional boiler repair specialist, as replacement may be required. Ignoring a water leak can lead to complete boiler failure, so time is of the essence. 

High Utility Bills

When a boiler is not operating at full performance, it has to work harder to produce heat. This extra effort can lead to a spike in utility costs. Homeowners who notice that their utility bills appear higher than normal should schedule a boiler inspection, even if the unit is producing the usual amount of heat. 

Low Heat 

Low heat in the home is another common indicator of a failing boiler. This often occurs when the boiler fails to heat water at its normal pace due to aging or a malfunction inside the tank. If low heat levels are due to the age of the boiler, replacement is typically recommended. It is important for homeowners to schedule an inspection if their radiators are not emitting the correct amount of heat to minimize the chances of catastrophic boiler failure. 

Early Detection, Efficient Repair

Boilers can fail for a variety of reasons that range from minor issues that require minimal repair to severe damage that requires immediate replacement. Knowing what signs to look for and contacting a boiler professional at the first sign of a potential boiler issue can help to ensure early detection and prompt, efficient repair.
