Ok so my old Ariston boiler stopped working and instead of fixing it and maybe keep spending money on it to keep it going I have decided to get a new boiler.

So I have been quoted a good price by a recommended plumber and I am stuck on which one to choose.

So the first choice is the Vaillant Ecotec Plus 824 and the second is the Worcester Bosch Greenstar 30Si.

Now to my limited knowledge the only difference is that the Bosch boiler has a higher flow rate at 12 and the Vaillant has 9. But then I am not sure if this will be a noticeable difference? I have also heard that Bosch's customer service is excellent and better than Vaillant.

Now the difference between the 2 boilers is £108 with the bosch being the more expensive, they both have 5 year warranties as well.

So I am really stuck in deciding which one to go for?

Gah lol still not 100% sure. I was leaning towards the bosch because of the great customer service. But then the guy doing it is an approved fitter for Vaillant so maybe thinking about the Vaillant.

My place only has 7 rads and is a mid terraced 3 bed. The old Ariston is a 23kw with a flow rate of around 12 (this is what the other plumbers I had in said after measuring it from the tap anyway). Hence why I was a little unsure about going for the Vaillant at flow rate of 9.

Daff Duck the problem you had with your bosch was this when it was out of warranty? As this would probably sway me if they did that out of warranty.
 
Because people will go with a big company as they trust them more. And the independent plumber who has quoted £1000 cheaper has to be dodgy at that price surely! Or so my friends told me when talking about their boiler replacement. So glad I don't think like that!

I also got a quote from BG for 2.5k for my straight swap from my old combi to this new one, and that's with a £400 discount! The guy I'm going with is £1680, installed a friends boiler and did a good job, so I'm happy, just got to choose a boiler Gah!
