We currently have an Ideal Classic RS360, but are building a new kitchen extension so want to take the opportunity to replace it with a newer condensing model.

Worcester Bosch seems to be the make to get, but which one is an equivalent output and design to the one we have? I know it's not a combi so is it Regular or System? I reckon it's the 18i or Ri

Im not a plumber but after fitting a Keston boiler, I wouldnt recommend one. I would go for a Bosch or a Valiant.

I had a Worcester Bosch fitted just before Christmas, very impressed so far.

As an installer I would say that Worcester aren't as good as the some people like to make out,I have fitted quite a few in the last 3 years and they are not without their problems,much like most other makes.

From experience, don't get a new Ideal (ours at home is utter crap, and has been since new).

I have half a dozen Worcester Bosch boilers fitted in my rental places, they've all been excellent, no issues at all.

Purely from own experience, I would say Worcester Bosch.

If I had time, and the six flue extensions were compatible, I would be changing the Ideal for a Worcester, even though it's only six months old. I'm already seeing regular repairs looming....

Thanks for all the advice, but to clarify, I'm asking which Wocester Bosch boiler is equivalent to the one I have.

Greenstar 18ri is similar.

Not being funny or questioning your knowledge at all, but what gripes do you have with Worcester? I've only been doing plumbing for 3 and a half years, technically still an apprentice. So I've only had experience of fitting modern Worcesters, which havn't had many serious hiccups yet

The older ones I have repaired have been tricky. Diverter valve on the old CDI is a joke.

O/P. Not sure what heat output you require, but if you are replacing it with another conventional boiler. I'd go for an RI instead of a CDI if you can get away with it it. They are much easier to install and if you are lucky you might get away with not having to run extra cables to the boiler, which you would definately need to do if you fit a CDI.

Said it on other posts; Vaillant are good from personal experience, However, depending on whether your heating system is new or the boiler is a replacement there is a bit of a design flaw in some models.

We have an ecoTEC exclusive 938 combi which is great, except for the fact that it has a plastic impeller on the pump that is susceptible to damage from particles in the heating side. Debris can damage the impeller which then goes out of balance and knackers the bearings. Apparently this is due to Vaillant booting out their third party pump supplier and going it alone for particular models with an in house pump, which is ste. I havr no idea which boilers they have done this tweak to, only going by knowledge passed from an approved installer who's less than impressed by their design. Still, good price and quite efficient really. Just something to be aware of.

We went through 3 pumps (under warranty) in the first year until we could get all the rubbish out of the system. We replaced all 18 radiators and have a MagnaFlow and inhibitor installed. Finger crossed.

Dr Rick, Just out if interest, did you have your heating system powerflushed when the boiler was installed?

To be honest, no we didn't. Hindsight being 20-20 and all that would suggest that we should have done, but hte plumber went for fill-empty-refill-empty a number of times. Up here in Scotland we're not on water meters so there's no real grief for using that sort of volume of water. That and the good rates we were getting for the install, the fact that Vaillant replaced the pump under warranty due to a known design flaw and that we were replacing all the radiators (in phases when money was available) I don't think we fared too badly.

We've now had about 18 months without incident and have added the bonus feature of the MagnaFlow just in case. I'll open it up once we're done with this snowy spell and see what crud has accumulated.

Best and cheapest arn't words that go well together with boilers. Even a straight boiler swap can turn expensive.

You need to take a condensate drain pipe into a suitable outlet. You will most likely need at least a 22mm gas supply, chances are there is only 15mm feeding your boiler. The heating will need upgrading to fully pumped if it isn't already and you'll mostly likely need to run extra wires to the new boiler as most new ones have a pump over-run facility.

If your boiler is next to the gas meter, on an outside wall, with a drain nearby and the airing cupboard directly above, it'll be a doddle.

If not, like most jobs, it'll be a PITA
