Vented system to Combi

[Rob Foster]

20plus year old non condensing inefficient boiler with old copper cylinder. Was going to upgrade to unvented and new system boiler but big Combi cheaper and more convenient.

Quite honestly you are probably
much better keeping your existing set up
most modern boilers are all rubbish and the combis even worse, loads of people make loads of money specifying, selling and fitting in reality pathetic units, that will not last
7 years or even less.

Personally I feel replacing a low pressure system to a combi the pipework has already stood the test of time and it is time to fully replace all system pipework! Been to countless installs where there are leaks due to system pressure change.

Had the pipe work replaced recently, was all 8mm micro-bore when I moved in. System has a pump on it at the moment anyway.

Just a toss up atm between a very expensive Baxi Solo which works with niggles, or upgrade to Combi.

Expensive in what way? Gas usage?

Thanks appreciate the advice. I have taken all into account, and a 35-40kw chucks out enough water for us. We have good mains pressure also. Given a Combi is around 1500 fitted with 7 years warranty I’m happy it’ll pay for itself as the winter gas bills were extortionate on current set up. I initially was thinking of keeping the system because of said points, however most recent plumber asdvised bigger Combi would be fine.

Combi conversion for £1500!!! Wow

Yeah was very expensive to run over winter. Given its old and non condensing I guess it shouldn’t of been a shock.

Why wow? Days work with £1050 boiler/flue.

[Riley]

Is he flushing the system?

I suppose if the guy works through his lunch lol

I'd be very wary of the plumber willing to do a boiler for that price

Pipe work is about 3 months old with a magnaclean already fitted.

Have they asked for cash?

 

[Riley]

I’d still be dubious, have they mentioned gas pipe sizing? I’m sorry it’s way too cheap. Are they all gas safe??

 

[Old UKPF 108122]

Any other irrelevant, non constructive comments?

 

[Riley]

You’re asking for professional opinion we are giving you professional opinion it’s way too cheap to be a quality job

Yes. As said gas is 22mm. Why would you think I should pay a plumber more than £450 for a day? Boiler is going in the same place as original and they need to do some alterations in the airing cupboard. Or are you all the 1k a day plumbers/brain surgeons.
