Hi

I have a Worcester Combi Boiler, fitted c 8 years ago. I constantly have to manually re-pressurise it and 3 years ago paid over £600 to have it descaled and serviced as well as trying to find the problem with the depressurising (perhaps I would have been more economical fitting a new boiler!). Anyway, I live in a ground floor 3 bed flat with garages underneath which does not help, but I would like to know before I go and spend more money on an engineer if there is anything I can do to help the performance of the boiler. I am having to turn my thermostat up constantly and whilst the rads are hot, the rooms do not feel that warm. (I do have double glazing).

How long should a boiler last? Are there any known problems with the Worcester boilers (I understood they were one of the better ones) How do I find out it I have enough rads / or if they are placed in the correct areas of the room? I would need someone to do all the work for me, but I don't want to appear ignorant if I do get people in to quote for me!

Thanks!

if the rads are hot its not the boilers fault they should reach around 80 if they do. then they are to small for the rooms or are of the old non convecting type or you have poor insulation values

Hi Clairy,

WB are allegedly one of the better makers.You either have a leak somewhere or the PRV is dumping water,we need you to check for both then post back.

Hi Steve

I'll get onto that - not being technical (or blonde!) what is a PRV?

Claire

Hi Claire,


Pressure Relief Valve - the pipe that goes outside from (normally) just under the boiler. Put a plastic bag/balloon on it to see, unless you spot it.

Hi - I have a different brand boiler but have had the same issues as the previous poster. It is so frustrating to feel ignorant and that we possibly have a lemon boiler (Weil-McClain). It's only 9 years old and in the past 3 years we have spend over $2000 on various repairs!

Anyway, the tank off to the side of the boiler drains water into a tub we put under the pipe coming out of it. However, this is usually after we've had to adjust the psi up. We have seen no leaks anywhere around any radiators.

Further, several parts have rusted out and/or burned out - hence, the costly replacement repairs. They claim it's because our basement has so much moisture. Yet our basement isn't wet, there's no condensation on the walls or windows. A friend suggested there is condensation dripping within the boiler unit itself. . .

A new boiler will be around $6000. This is a lot of money, especially after just putting so much into the existing one. Help! Advice? Thanks!

Hi,

I'm not familiar with that make, obviously, but if water is being dumped after pressure going up, then PRV is leaking below normal blow off pressure approx 3 bar + (45psi)
If this is happening change PRV .
