Why has my boiler broken down? If we had a euro for every time we have heard that in the 40 plus years we have been trading, we would have retired by now. A boiler is made to last. If taken care of properly they should last 10 to 15 years on average, some commercial boilers can even last up to 50 years.
When asked why has my boiler broken down it can be a number of reasons as you will see below but here firstly we will try to explain the preventative measures you can take. A good analogy is to think of a boiler similarly to a motor vehicle. If you had a van for example a you put it in your garage in March and do nothing and go to start it in September, will it start? A boiler like a van is an engineered piece of equipment with different parts all doing a different job. An engine can seize up for a number of reasons without use, over time with wear and tear a boilers parts can wear out, seize up or start working intermittently. We annually N.C.T. our vehicles, we should also annually service our boilers for exactly these reasons.
When the warm weather arises and we stop using our boilers we would advise once a month to switch your heat on a high setting for 20 minutes. We understand that you don’t need the heat but for the small cost of giving your boiler a work out this ensures the parts are functioning correctly. The same as you may start your vehicle that is in the garage once or twice a month even though you are not using it.
Why has my boiler broken down? A few reasons provided by our experts.
- The diaphragm valve may be broken or faulty. This valve is used to regulate or stop the flow of liquids or gas in your central heating system.
- You may have an Airlocks, an airlock can disrupt water flow in your plumbing system.
