The long, cold months of winter are demanding on all types of boilers. While boilers tend to be especially reliable, they are not immune to problems. It’s best to call for professional maintenance at the first indication of a problem. Acting fast helps to prevent further detriment, more high-priced repairs plus potential updatement of the system. A common sign that there’s something wrong with a hydronic heater is excess water surrounding the boiler tank or the connecting pipe. Over time, boilers can accumulate ruse plus components wear out. Aging seals, a faulty pressure valve, loose fittings or corroded pipes can lead to leaking or dripping. Another warning sign is different operational noises. When the boiler sounds a lot like a tea kettle reaching a boil, it’s called “kettling.” Rumbling sounds are also cause for concern. They regularly mean that the heat exchanger has developed a deposit build-up, kettling is usually the result of strenuous water but can happen to any boiler at any time. Deposit accumulation on the heat exchanger forces the boiler to work harder, which shortens its lifespan plus results in higher running costs. In especially cold areas, condensing boilers can have difficulties due to the condensate pipe cold. The water freezes plus creates a blockage. This issue is really solved by applying boiling water to the pipe. Older boilers often experience complications with the pilot light. This red flame, situated underneath the unit, is necessary to operate. When the pilot light shuts off, it is truly the thermocouple. It’s sporadically possible to just reignite the flame. However, the boiler might not be receiving any gas.
