A broken boiler can be extremely inconvenient. They are expensive items and it is important to keep them well-maintained to extend their lifespan.
Six of the most common boiler problems are outlined below.
1. No heating or hot water
This is clearly a major issue but there are a variety of possible causes, including power supply issues, fuel supply issues, thermostat malfunction, frozen condensate pipes, low boiler pressure, faulty electrics, or a broken or damaged pilot light on older models.
2. Boiler is leaking
Leaks are never a good sign in general and boiler leaks are usually caused by either a broken internal component, for example, a pump seal or pressure valve, the pressure being set too high, corrosion, or simply poor installation. The precise location of the leak will often reveal the cause.
3. Boiler is ‘kettling’
Kettling is a strange rumbling noise that is similar to the noise a kettle makes when boiling, hence the name. This can be caused by a build-up of sludge or limescale in the heat exchanger, which can restrict water flow and can cause it to overheat and boil.
If you are in need of a boiler repair in Gloucester, there are plenty of expert firms with resources available online, such as the examples seen here www.hprservicesltd.com/gloucester-boilers/boiler-service-gloucester/.
All boiler repairs/installations must be handled by a Gas Safe engineer.
4. Boiler is making other strange noises
Boilers can make a number of other noises in addition to the kettling noise outlined above. Most noises indicate a fault of some kind.
If there is a banging noise, this will usually be an issue with the pipework, heat pump, debris in the heat exchanger, or an internal component coming loose. A clunking noise usually indicates loose pipework or an obstruction to the boiler fan. A buzzing noise may indicate faults with electrical components. A loud humming noise may indicate a loose part.
5. Low boiler pressure
A sudden change in pressure will usually indicate a significant problem. Issues with low pressure are reasonably common and are usually caused by water leaks, a faulty pressure relief valve, or radiators that have been recently bled.
6. Boiler switches itself off
There are a number of reasons why a boiler could be switching itself off, including thermostat failure, too much air in the system, reduced water flow, or a build-up of sludge/debris within the system.
