Boiler Needs a Service

How to Know when your Boiler Needs a Service

Boilers are a feature of most modern homes; your boiler ensures that your central heating is running, and that you have hot water when you need it. Most people will have their boiler serviced annually, and providing you keep some checks on the running of things, this should be all it takes for your boiler to last a long time.

Don’t think that because you have an annual service your boiler will run properly all the time. Keeping a check on things means that you can have any problems dealt with, before they become serious enough for your boiler to stop working altogether. The following is a list of things that you can check regularly to ensure that your boiler is running efficiently. Most of the things mentioned here should already be explained in the literature that came with your boiler.

Check Your Water

It is a good idea to check that your water is hot enough and that the water levels are optimum. You should check that the levels are right on a regular basis, and at the same time you should check the water cut off system. If your water continually runs cold, or you run out of hot water altogether, then you need to call in the professionals.


You should check the temperature on your boiler, and the operating pressure, on a weekly or even daily basis. Check the low water cutoff at the same time as the temperature. You should check the combustion on your boiler (most boilers use gas, but it might be oil, wood or electricity). This ensures that the boiler has an adequate supply of air. You should also check the pressure of the water that is fed into your boiler regularly.

Checking the Feedwater Pump

Water is fed through into your boiler through a pump. You need to check that the pressure on that is at optimum level if you want your hot water and heating to continue as they should.


Many boiler systems operate on gas and you should check the gas pressure on a regular basis, at least twice a week. At the same time you should check the flue gas emissions; your literature will tell you what they should be. Recent legislation requires all boiler services to include that check. If the reading is either too high or too low and you cannot seem to adjust it, then call in a professional. You should also check the temperature of your flue gas when you check pressure and emissions.

Checking your boiler on a regular basis may seem like just another chore to incorporate into your already busy lifestyle. If you want to avoid the heavy cost of a new boiler, checking all these things on a regular basis should keep things running well in between professional servicing. If you find a fault, and you find it early enough, this could save you the cost of expensive repairs, or even a new boiler.
