Your gas boiler is a very important part of your home, it supplies you with constant hot water as and when you need it, and keeps you warm when the weather turns cold outside.
So how do you know when it’s time to replace it?
Most boilers these days have a lifespan or around 10-15 years, that’s not to say they won’t last longer.
If your boiler has been maintained on an annual basis then it should last a long time. Maintenance is the key to keeping your boiler in good shape.
As your boiler reaches 10 years of age, it’s a good idea to start considering replacing it with a new up to date high efficient model.
Yes, I know 10 years seems a short time for the boiler but it’s the world we live in now. Nothing lasts like it used too.
Have you noticed your gas bills starting to rise?
If so, this is a sign that the boiler is having to work harder to produce the hot water and heating needed. If your boiler is not a condensing version, then you are already wasting around 35% of your gas through the boiler flue.
All boilers produced today are high-efficiency condensing models, they are rated grade A, their efficiency is around 90%, when you compare that to a grade G boiler which is around 55% that’s a big saving of 35% on your gas bill.
Does you boiler tend to stop working on a regular basis?
If this is the case, it’s a sign that things are only going to get worst in the future.
You have to stop and start thinking how much more money are you going to throw at the boiler to keep it working. Don’t forget though the boiler is old and no matter what spare parts you replace, it’s still old and uneconomical boiler.
As a boiler becomes older, the spare parts needed to repair also start to rise in cost, this is because the rarer they become the higher the costs become.
Most of the older boilers have a spy hole to check the colour of the flame when it is working. If the flame on your boiler is burning a yellow colour, then this is not a good sign. The flame colour should be a nice crisp blue.
A yellow flame is a sign on carbon monoxide problems, and my advise would be to isolate the boiler and call in a Gas Safe Registered Boiler Engineer to check it over straight away.
Don’t forget you cannot see, smell or taste carbon monoxide.
Does your boiler regularly loose pressure and you have to top it up to get it working again?
This is another sign that things are not right, any form of leakage from the boiler needs to be addressed. Otherwise the boiler will eventually stop altogether.
The boilers of yesterday have almost gone, yes, they lasted a long time, some around 40 years or more, but they were very bad for the environment and wasted up to 40% of your gas through the flue.
The boilers of today is better for the environment and a lot cheaper on the running costs, but, and this is a big but, they must be maintained and looked after, otherwise you will find you will be paying out for big repair bills when they go wrong.
