Worked Well For Four Years, Now Junk.
After four years of running smoothly, now it's starting to give one fault after another. Service every year. Wouldn't recommend it.
Boiler
this is the most pathetic useless pile of **** ever. It is so complicated I can't get it to work. I hate it.
Ignition Fault
Just moved into house 9 months ago which came with a valliant ecotec plus 831.
It came with a transferable 5 year warranty. It was transferred to my name and expires at the end of 2018.
However, had an ignition fault and thought no problem, I'll just call them.
How wrong was I.
I was informed that the boiler should have been serviced in April and because it wasn't, It's no longer under warranty. I intimated that they never contacted me to arrange a date to have this done. There reply was, "we don't" contact you, It's up to you to contact us.
I was with Scottish Gas in my last property. They would call once a year for the boiler service, and a mutual date was arranged. No problems.
I asked to speak to somebody in authority to resolve this but there was no way this was going to happen. It's company policy, I was told.
Useless customer services. Unflexible, unhelpful. Not a professional service at all, and it took me 30 minutes to actually speak to someone.

Vailliant Eco Tec 5/5
we bought this boiler 3 years ago and every thing was fine however all in the winter of 2016 its had nothing but pressure problems iv asked Valliant to fix the problem but there costumer service is 1 of the worst I have to deal with in my life, to the point were iv asked to speak to management who have not called back it taking 3 months of pressure problems with no fix in sight, if your thinking of buying from Valliant don't, people think that there the same boilers form years ago and they art, there costumer service is treble with no one finding my problem and the charge £90 for any call out, the staff have pleasant telephone manners but put the phone down when they get confused the waiting time can take upto 25min, and u still don't get the problem fixed, my biggest regret is not reading hese reviews before buying one, so save some money because these boilers arnt worth what they once were
I agree mine's only been in 18months and had to have 2 pumps fitted they came back with system needed flushing but it was done before when Boiler fitted now just been done again.wish I'd never heard Vaillant would not but one again junk

Bad Boiler Manfacturer
I am a Vaillant approved installer. I have installed many vaillant boilers over the past five years. They used to be good boilers, but recently I have had problems. Over the last 6 months I have had 3 boiler leaks straight after installation which that creates a bad impression with the customer of my work. Vaillant customer service (VAILLANT GROUP SERVICE) is so bad, it takes them so long to answer the phone. Then when you do finally get through there is no priority or urgency, they will not send somebody until the next day. The quality control is seriously lacking, these boilers should not be passed and making their way to customers.

3years In And Perfect
Had boiler 3 years now. It fantastic,
instant hot water when you turn on tap
Lower gas bills than before
Small compact yet so powerful
Owner can adjust water temps themselves
Almost silent running
Love the anti frost check it does before firing up. (Sends slightly warm water round system to check and clear frost while warming the pipes)
These are just a few things. Really has made a difference to my home. Now getting same boiler fitted in other family homes.

5 Years And Not One Problem
Installed on recommendation by our plumber ( as that is all he will install). Came with 5 year warranty providing serviced every year. Just had the 5 year service, a major one, compared to other services ( replaced seal etc). It has been faultless over the past 5 years and the plumber said we should get at least another 5 - 7 years no problem.
Quiet, near instant hot water and runs without a problem.

Vaillant, Used To Be The Best, Now Among The Very Worst.
I am an installer and like many other installers remember the old sine and other Vaillant boilers well. The best there ever was, made in Germany.
Now they are made in China they are nothing but problems. The customer service is non existent. They fail from the beginning, but a common tale of woe is how they suspiciously fail very often just outside of warranty.
I would never recommend one of these boilers as they cause endless customer relations issues. It really reflects badly on us.
You could easily put in a cheap boiler that would go on for 10-15 years without a single problem, for the price of just one of the parts on these boilers.
These really are the TVR of boilers... Expensive unreliable rubbish. (With a few flashy bells and whistles)

Best On Market
Best boiler you can buy. Most of the faults people list are because of poor instalation, non flushing of system or leaks in system pipe work. If you use a Vaillant advanced installer you get a seven year no quibbles guarantee as long as the boiler is serviced. All servicing is from the front, all components can be accessed or removed easly if needed.
The hot water is hot and the warm start saves gas and water.
Q&A
Is ecotec plus 831 compatible with v smart thermostat?
Boiler not working and F22 flashing on and off. What does this mean?
I am trying to establish the age of my Vaillant 831 boiler. Can you let me know please when this model of boiler was launched? Many thanks.
Our new Vaillant Ecotec plus constantly cuts out due to low pressure. We had the the system flushed and magna clean added. Vaillant replaced the pressure sensor but still no joy.A few visits later a vaillant engineer could see water dripping from the heat exchanger so it was replaced. Two months later the pressure cuts the boiler out again and their so customer service say that a block has been put on our warranty meaning it has to be a problem with system & not the boiler.We now have to pay for an engineer to visit to prove that there is no problem on our system. We are wondering whether it's fair or legal to block our warranty and make us pay for a shoddy product?
My boiler kept cutting out due to soaring pressure. After charging up the pressure it would work again until it went off the scale and so on. My engineer told me it needed a new expansion vessel. He fitted one at great cost (he told me that the spares depot had dozens on the shelf because they fail so often) so I asked Vaillant if this was a common problem. They didn't answer my question so after the new one was fitted I sent the old one to them. They checked it, increased the pressure (which was at .7 bar) to 1 bar and ran it on a boiler. They said that there is nothing wrong with it. My engineer is upset - he said what else could it have been if the boiler now works 100% when all he did was change the expansion vessel. It has been regularly serviced in accordance with the manual including pressure checks on the vessel. Have you any idea what might be the explanation for all this?
I have had my Vaillant Ecotec Plus Combi 831 for 7 years. I have had a few problems, but nothing really serious. What is the lifespan of these boilers? I have seen several reports with different results.
My boiler has stopped working with an F62 error code. What does this mean and how can we get this fixed?
