Plumbers - combi boiler question
 

Hi ,

My 30 year old boiler has gone pop , thinking of taking hot water tank out & fitting a combi boiler .

Any one recommend a good combi boiler ?

Thinking of a Worcester Greenstar 27 CDi or a mate said he can get me a Ferroli optimax boiler cheap ...
Never heard of Ferroli any plumbers in the org ?

Any ball park figures for a plumber to fit combi & remove hot water tank ?

Cheers Steveg

Screwfix forums are useful for info on that sort of thing. Basically Worcester/Bosch or Vaillant seem favoured for reliability. Steer clear of others.

Various views on combi vs system (hot water storage cylinder). Personally I'd keep a system boiler if the rest of the "system" is in decent nick. Combis do have advantages in some circumstances, but there are downsides too.

interesting - will have a look on the screwfix forums :) just bought a house which has been stood for a year, sediment was coming through the hot water system but it seems to have cleared now, although the sf forums could be a great place to get advice about upgrades such as this :)

Ive got a ferroli combi, touch wood never had any problems, my mates a plumber and recommends Worcester Bosch boilers.

Definately Worcester-Bosch, excellent boilers.

Mine is now 3 years old. I did have a problem with a leaky internal pipe where the manufacturers appeared to have bodged a stripped plastic screw fitting and it cost me their standard £170 call out/service/fix. although they also replaced a couple of components as well as the knackered pipe.

mine is a 28 cdi. issues are speed to fill a bath and the water temperature. the only way to get the temp as hot as I like is to run it slowly and takes 5 mins to fill bath etc.

topping up the water system is puzzling first time as you have to insert a plastic key and then open the fill tap.

We are starting to fit the Worcester Greenstars at work, so should be O/K. Combi boilers are O/K but a lot of things in them to go wrong. If rest of system o/k you could go for a condensing boiler. I have a project at work and doing just that, plus gives you immersion heater back up if boiler/gas fails!Also considerably cheaper.

Re: Plumbers - combi boiler question
 

There's no more things in a combi boiler than there is in a system so plenty to go wrong with both. I agree with the immersion heater back up though. I think any new boiler that's fitted now is meant to be a condensing boiler as that's the current standard.

Another thing to think about is whether you're replacing the entire system or just the boiler, if you have showers/baths etc as Tim says if you want the water at a hot temp you need to run it slower.
