Court summons arrives in the post at 11:45, central heating

Vaillant ecotec 831 boiler fitted less than 5 years ago.

Faults to date ...

Design fault, a rubber ring to be replaced by a graphite ring.

Design fault, a pressure sensor gives up the ghost.

2 weeks after guaranteee expires, the change-over valve fails
but exhibits water leak that has been there for months. Vaillant
refuse to honour under the guarantee.

Vaillant pressure us to take out extended warranty, which we do
because of change-over valve replaced. When the small print comes, it
specifically excludes any faults that existed before the guarantee
so cancel the policy immediately.

Thermostat fails requiring use of manual override.

Yesterday, rubber expansion joint fails. Emergency engineer says that
it is another design fault having a rubber hose next to the heat
exchanger, and that replacement will be a telescoping metal joint.

The emergency engineer says that our experiences both with Vaillant
and with theor boilers are commonplace, and that he always recommend
Worcester boilers.

Moral : Don't buy a Vaillant boiler, not only are they crap but
Vaillant have a predatory attitude towards customers' bank balances.

I'm really surprised - I've always regarded Vaillant is one of the best
manufacturers.

I've always found it to be so, as have others I know who have used them.
Of course, the satisfied customers rarely bother to post threads about
how happy they are.

When we had a new boiler three years ago it was a toss-up
between a Vaillant and a Worcester Bosch. The installer recommended WB -
mainly because, he said, they had a first class produce and excellent
after-sales service.

and, looking at the trade discounts I can get on both makes, a bigger
profit for the installer.
