Common Boiler Problems to Look Out For this Winter!

It's never a good deal when your boiler suddenly breaks down. You might encounter different problems with your boiler. Inconveniently losing your home's heating and hot water is one of life's most vexing experiences, especially in winter. 

We've put together a list of some of the most frequent boiler problems you might have to face and an explanation of their likely causes.

Boiler Leaks

Most boiler leaks result from corrosion of the heat exchanger or boiler piping, including a pressure valve or pump seal. If you see a leak from the pressure relief valve, your expansion tank or PRV might be the culprit. 

Corrosion surrounding your system's pipes may be the cause of a leak. It's also possible that something went wrong setting up your system.

Low Pressure

If your boiler has a built-in pressure gauge, a typical home heating system should have a pressure of 10 - 15  PSI at all times. Your boiler might not heat all your spaces if the pressure is too low. 

It is possible to have low boiler pressure due to system leaks, bled radiators, or a broken seal or part.

No Hot Water or Heating

It might be irritating if your boiler fails to produce hot water like it’s supposed to. Your boiler might exhibit malfunctioning motorized valves, damaged diaphragms, airlocks, broken thermostats, back drafting or ignition failures. 

Take Away

Keep in mind that you should only execute boiler inspections that are safe and simple. Trying to solve the problem on your own can be dangerous. Boiler services from Capital Plumbing includes a team of fully competent staff to diagnose and solve any issues.
