The radiators on my system are about 30 years old & the bolier about 18 years old. I want to fit a combi boiler but have been told due to the age of my old system & I have to have new pipework & radiators, a complete new system. The engineer told me not to flush out the system as the combi boiler would break within a year. I have another engineer coming out who says flushing out the system is fine but I may need some of the radiators replacing but not the pipework. Who do I believe?

If the system is a two pipe system then the pipe work should be fine and the radiators well a lot depends on what type of hot water cylinder you have primatic single feed or an indirect with a separate feed and expansion tank. The latter may well have had fernox or some other inhibitor put in the system over the years and the rads will be reasonably clean inside. Ever had a rad off for decorating what was the water like? do all rads get hot at the bottom in the middle if not a sign of sludge.
If you have a primatic then yes a flush out would be recommended.
The other thing to look at on the rads is the spot welds down each seem, they need to be about one every 1.5" any thing more and the radiators could fail should the pressure in the system get up to 3 bar ( and it will at some point ) Also have the valves changed if old.

I would go with the second guy unless the pipework is really poor condition and leaking - flush the system and put an in-line strainer on the pipework and the boiler can't be harmed. Check out the FERNOX site for the boiler buddy - they are what Worcester Bosch engineers recommend. xxx

With a system of that age I would agree that you should replace the radiators at least. There is a good chance that the pipe work will be full of deposits as well, so all in all it may be a better long term bet to start from scratch and avoid any future problems. It depends a lot on your water quality and whether you have had inhibitor in the system from early days?!

If your investing some money in a new boiler I would suggest replacing any and all piping you can. The PSI (pounds per square inch) may be different with the new boiler and the old piping may not handle the extra pressure. I've seen ( I see) old pipes break because of a new boiler pumping extra pressure (2 psi).....even a change of 4 psi will blow an old pipe.
hope i can help....send an e mail for any more help

keep the pipe work if theres no leaks but change all rads and
fittings for new 18 years is agood long haul for a boiler so youve done well.

the ignition occurs while there is no flame sensed frequently led to via a undesirable ignitor, gas valve or flame sensor call your community heating contractor..... your situation might something so ordinary as a maintence situation the two way you have gotten a provider circulate to chew the bullet and decide earlier you are attempting a restoration the challenge and probable nake it worse than it needs to be

It is hard for either of them to guess how long something that old is going to last. Both lots of advice sound OK but who knows how long things will last ? Liken it to a car.
