This was delivered new with known faults for which Modification kits were available. The main circuit board failed and knobs broke off requiring circuit board removal to replace them. An internal plastic flow pipe collapsed meaning hot water flow was reduced to a trickle. Frequent topping up is required or you get a dry fire and on occasion it dumps the water pressure. This is the worst boiler I've ever owned..... When it dies I won't be buying Vaillant again. We thought we bought a Rolls Royce but, got a Lada.

Don't, just don't. Had this boiler for 6 years and had just as many repairs, the last one less than 3 weeks ago and it's broken again. Engineers keep exchanging the pump which usually fixes the problem for a couple of months. But really they don't have a clue what's wrong. While it was under warranty this was merely annoying, but now that it is out I'm faced with constant repairs to pay for or replacing the whole thing. Absolutely dreadful boiler.

Customer review

Terrible quality. During 5 years of guarantee, it has had 4 major parts replaced, the expansion vessel at top didn't work from day 1, pump broke with water dripping from the bottom, external pipe dripping all the time when it shouldn't be, had a failure between Christmas and new Year leaving us without hot water for days, and the list goes on. How can Vaillant produce such a pile of rubbish? Their customer care is then only interested in charging us for call out fees and selling insurance. Not interested in solving the problem. Nasty bunch, stay well away from Vaillant.

Do not buy a storage boiler, just more to go wrong. Our Valliant Ecotec 937 has a pump for the storage tank which has failed at 4 years. We missed one service in 4 years, and even though it has just had a service Valliant won't honour the guarantee. Why not? If there was a problem, it would have appeared this service. But no, it is a get-out. So avoid Valliant, and avoid storage boilers. I am now £300 out of pocket to have it repaired.

5/5

the 937 is a fantastic boiler.90 pumps out of 100 fail due to muck in them due to a system filter not fitted or system not flushed out correctly.ALL gas boilers need to be serviced on an annual basis.all boiler makers who offer extended gtes insist so.5 YEAR GTE = 4 SERVICES !

Run Far Run fast!!!, Firstly the pump blew up after being installed for 15 months, leaking all over the place with Central Heating fluid. Warranty is not 2 yrs its a conditional 2 yrs( boiler must be serviced within first year for the second year of the warranty to be valid, they like to keep you in the dark about that), most other boiler manufacturers offer at least 5yrs warranty as standard, hmm (Vaillant must not have much confidence in the Quality of their own product to offer such a low warranty period). Secondly Vaillant telephone support didnt really seem to care either, 3 days to get an engineer out to look at the bolier and Im without central heating or hot water in the meantime!!!.
Telephone support, even though the offices are closed you ring them on an 0870 number and they say all our operators are busy at present!!!(there is nobody there, they are sucking me dry in telephone charges, even though the staff arent there!!).
In the end their engineer never turned up, so I had to pay out for an engineer myself plus a new pump!!.
