All new central heating needed?

MagsyB

Hi
We live in a terrace house built in 1974. It has an old (?original) boiler which we know is going to need to be replaced.
The difficulty is that I think the whole system will need upgrading but the OH disagrees. The reason for my flamboyant disregard for moneysaving is that the pipes into the exsisting radiators are really thin much thinner then any pipework I have ever seen(!!).
So what do you think and if it does need replacing would it be cheaper or more expensive then having it newly done - ie replacement pipes going in the same place but they would all also need removing - iykwim

thanks in advance for your advice

I think you are talking about microbore. Usually 10mm occassionally 12mm or 8mm. If it looks really small it is likely to be 8mm. I wouldn't have thought it needs replacing, just be careful not to bang into the stuff as, IMHO, it has a tendancy to move in the radiator valves when bumped, and subsequently a small leak develops.

Our original central heating system was installed in March 1969 it has been modified and upgraded a few times but the original radiators and pipe work are all O K.

Our CH system is at least 30 years old - original boiler, too. We have had to replace every radiator in the past 6-7 years as thay have corroded and sprung leaks. They have all been replaced with double rads that seem much more efficient, but we have had to shop around to get them as they haven't necessarily been standard/popular sizes.
