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?

we have a Vaillant boiler and its not missed a beat in the 6 years or so its been installed, but what was really interesting was one of the British gas home-care guys complimented me on it when doing the service.
He was saying he wanted to get one for his new place but couldn't afford it yet, said Vaillant was the best make on the market and they hardly ever had call outs to fix them...

No idea about the Bosch though i'm afraid.
 
My mum has a Vaillant, and it's been going strong for a good 10+ years, we've also got one in both of our work offices, and I've not seen an engineer out to fix them since I've been here (although that's only a year :p)
 
Most of the guys on the heating side of my firm swear by Worcester-Bosch and their service department. Vaillant are good also, I don't think you would go wrong with either and viessman are also fairly good.

I had central heating installed at my house 2 weeks ago and I went with Bosch.
 
The max flow rate will be determined by the water inlet pressure, there's no point in buying a boiler with a high flow rate if there is not the pressure to support it. If you don't have many rads then it's not an issue.

I would personally go with the Vaillant solely based on what I have read on other forums and the fact that I have one and it has not let me down and is simple and easy to use and does not have a digital pressure gauge (less electrics to go wrong).

I was recommended the Vaillant Ecotec Plus 831 to heat 10 Rads by the installer but he did give me other choices but I can't remember what they were.

How much is a new boiler these days? For a decent one? 4 bed house, hot water tank and central heating.

You don't need a hot water tank (unless you don't have enough pressure for a manual shower) as the condensing boiler heats water on demand.

I got a complete re-pipe, Vaillant Ecotec Plus 831, 10 new rads, valves, controller etc with 5 year guarantee fitted for just under 4k from a local company.

Edited to add... the Vaillant 5 year guarantee is only available from a Vaillant approved installer other wise it's 2 years, pipes rads etc will need to be guaranteed by the installation company.

Both are good in all honesty. A decent vaillant combi is around £900, then obviously labour on top of that.

Biggest thing with heating systems, is maintenance, regular flushing and use of an inhibitor will prevent many problems, even get the installer to plumb in a magnaflow to catch the crap floating around.

This is really important to note, your installer should clean the system and add a good inhibitor and have it checked once per year. I neglected this fact and ended up with huge problems after a 'plumber' drained the system and re-filled without adding inhibitor. Needless to say my rads rusted from the inside out and the system was dead within 5 years.
 
We've had solid sludge in our system, 2m of pipe had sludge that solidified to a concrete like form, had we had inhibitor in the system and regular flushing, we would not have had that crap knackerin the pipework and heat exchanger.

Powerflush is a waste imo, they cant shift the terminal crap.
 
Ours just packed in a few weeks ago and we had a Vaillant installed. I spoke to numerous plumbers & they all recommended Vaillant. Can't remember the exact details now (blocked out the horrific memories of the week of freezing showers etc).

It's a great little boiler, v quiet and you can set the heating/hot water temperatures as well as having a wireless programmable thermostat. There's also the option to have an indoor/outdoor thermostat which will throttle the boiler so if the temperature outside is warmer, it'll reduce the output of the boiler a bit. I'm told that over time this saves on gas bills and also results in a cleaner boiler as it isn't at 100% all the time. We didn't go for this incidentally.

Google it though, there's plumbing forums where people talk about it and to be honest there doesn't seem to be much in it.
 
I've just had a Vokera 29A installed, A rated and flow rate of 12.1 for £1,000 all in. Great boiler so far.

Not as highly rated as the Worcester boilers but much cheaper and those in the trade rate them well and you don't pay for a brand premium.
 
When we had some plumbing work done last year, the plumber we used recommended Vaillant when I mentioned we were thinking about replacing the boiler.

Just going by the places Ive stayed including my mums back in the day. She got her boiler in 1992 and its never been tinkered with since and is still going strong as are the rads.
