Bolier problem advice needed

[vallumlj]

Our boiler is coming up to 25 years old and we want to try and keep it going for a long as we can but have had a few problems recently.

The main problems are the pilot light goes out a lot and also once the room get's up to temp the thermostat would cut in and cut the pilot light.
Also if we turn the thermostat down it will cut the boiler light out. The boiler will fire back up if you give it ten minutes, the pipes also bang a lot. We thought we would get it serviced and the first plumber friend of friend said it was too old and would not touch and said it was nearly dead.

The 2nd a trust worthy plumber we think once again friend of friend seviced the boiler and said it was old but was ok he printed out tests and left them with us and he thinks the system needs a power flush as this is causing the boiler to kettle a lot and put the boiler under a big strain.

Since he has serviced it the pilot light has not gone out as much?

The question is do you think a power flush could fix the problem or could it be something else.

He said if we had to get a new boiler the system would need a power flush so if it did not work we would of had it done already.

Any help would be great.

Thanks

You are being very foolish keeping an old boiler going when its both troublesome and so inefficient.

You would save perhaps 35% of your gas bill with a new boiler!

Without seeing the water I dont know what it needs but chemical treatment may be as good.

Likely to make many parts of an old system to leak!

Just why are so many people so mean with their heating system?

I saw a £4M house with three almost new cars who would not spend £2000 on a new boiler which would save them £600 a year on gas!

Meanies!

Vallum, I would suggest you get the system cleaned mechanically and chemically, system upgraded to update controls and cylinder to present requirement. By doing this, your system will then be a little more efficient and also upgraded to accept a new boiler when present boiler dies.

It good and fine to at a stroke fit a new boiler, that is super duper & runs on a gnats fart efficiency. Such boilers will NOT be running for 25 years that your present has clocked. So, gather more information, get to know your system and what is required now if a new system was to be installed and then look for quotes/ upgrades to suit your pocket whilst specifying your chosen components

a powerlush is unlikely to cure your probllems
forget servicing
you need to ring a competent engineer explain the fault and ask them
to fix it.
sounds like pump.thermostat related

Telling us what boiler it is might help too!

yes petit it really does annoy me when we get the old "need help - but you need your crystal ball to tell what the help is required on"
the boiler is about 25 y/o but the maker could have run that line for 10 or 15 years after starting.
