As I am on a budget I will have to fit this myself (and maybe just get a CORGI registered plumber to fit the gas pipe and commission it) which model is best for simplicity of function, reliability and ease of fitting

Worcester Bosch and vaillant are known to be the best for quality and reliability, the site rich at hvac refers to gives ratings and rates boilers on efficiency, the difference in efficiency for modern boilers is minimal, if you buy and install yourself, you get a limited guarantee, use an accredited installer and you will get 5 years g/tee.

First thing to figure out is why the old one failed.Most cheap combi boilers have extremely small heat exchangers doing the hot water which have to work hard and quickly get blocked up with limescale in most parts of the UK. If you have any more than one bathroom/shower then you are going to need at least 12-14 litres per minute of hot water delivery. This sets the boiler size (heating power) at something like 30Kw which is twice what the average semi needs for the heating alone.One of the other responders mentioned Worster Bosch which is all we ever fit as plumbers because we dont want the phone calls afterwards - an undersized combi is an expensive and dissapointing disaster.Fit a Combimate scale reducer to the incoming cold water and the installation will last much longer.
The gas aspect must be agreed with the CORGI guy before you start and dont be suprised if he wants to put a new 22mm dedicated gas pipe in. The correct and legal paperwork is crucial if you dont want a problem when it comes to selling and the HIPS report cannot be completed.
Saving a few hundred pounds at this point could well be a seriouse mistake - you always get what you pay for with a combi.
good luck Ian C

In my opinion Worcester are the best, but they are by no means cheap.. It's definitely worth while spending a little bit more if you can afford it as a Worcester is bound to go the distance. Depending on the property in which the boiler will be fitted I'd go for either the SI or the CDI model, there are many different outputs to choose from however the main advantage with both these models is they have hot water temperature control so you can set the water temperature exactly how you like it. Don't forget to thoroughly flush your heating system though because there's no point connecting a new boiler to a filthy system, it will dramatically reduce the life span of your boiler and cause you no end of trouble... Hope this helps??

When i replaced my boiler i done the same as you are going to do.
I measured the location of the water inlet central heating outlets etc and went from there. I got a corgi plumber to connect the gas.
Make sure you are confident in doing the other work as you will get all sorts of problems!!

i think you are all missing the polnt here,you have to be corgi to fit the boiler,you can't fit a boiler in full stop.

According to the rankings at my source, Ariston, Baxi, or Ferroli are the highest rated units. You can get all the rankings on the brand rankings page at my source.

Have a look at a Ravenheat - I seem to recall they were quite reasonably priced.
