Vaillant EcoTEC Plus 831

After four years of running smoothly, now it's starting to give one fault after another. Service every year. Wouldn't recommend it.

this is the most pathetic useless pile of **** ever. It is so complicated I can't get it to work. I hate it.

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.

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 bought a boiler from my local plumber shop and valiant send a Ing and still the boiler don't work

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.

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.

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.

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 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.
