Good Boilers, Disaster of support after purchase!
As a gas engineer, we find Viessmann are a nightmare for support. No manuals are available, they rarely answer the telephone to provide support.
The boilers are great but once a problem a nightmare. They have not been able to provide plate heat exchangers due to hoses-shedding rubber which then blocks plates and heat exchangers.
Due to the lack of support, a pensioner since last Wednesday week was admitted to hospital and returned to the empty home with no heat. Been trying to get a bit of tech support but all you get is the mind-numbing music.
I am trying to get other jobs done so I don't hours to pray to get a response. 18 minutes waiting for an answer.

We are pleased to announce that we are currently recruiting and training two new technical advisors who are expected to be available to answer inquiries by mid-March.
