The documentation provided with the boiler is wrong in certain sections. Certain features are not available in certain modes of operation. The response to email queries is poor.

excellent service & solved the issue over the phone.

The company who installed the boiler were very poor. Dirty workman and did not resolve the air locked in the system which caused the boiler not firing up and showing the red triangle. To resolve this after,weeks of cold radiators I had to pay for the fitting of a pressure tank in the airing cupboard. Although this is not a Viessmann problem it did not reflect well on the overall experience.

It remains to be seen when the winter usage is compared to last year.

The boiler chosen is living up to our expectations, very quiet when providing the heat required. At the end of the day boilers are still expensive to run under todays price of fuel. But it's a top boiler to purchase.

I understood these were the boilers to go for, so we had our Worcester Boach 24 cdi replaced with a Viessman 050 30kw, the model recommended as a suitable size replacement. The installation went very smoothly but a few weeks later, hot water failed. A Viessman engineer visited and said it was a very small blockage in the impeller of a valve within the boiler, so replaced the valve with a filter to help prevent the same happening again. He was surprised a piece of grit (or whatever it was) so small would cause the problem but there you go. We can hear the pump working when the boiler is on so I asked him why the boiler is noisier than the 20+ year old Worcester it replaced, particularly as it is advertised as quiet. He said it has a higher output than the Worcester, so is bound to be noisier and that he did not consider it noisier than it should be. His comment made me feel like I cannot book an engineer to look at it without being charged, as he already dismissed it as not a problem. Additionally, occasionally the hot water just does not come on. we have to turn the tap off for a short while and try again. An intermittent problem like that is very hard to prove and you can bet it would work ok an engineer called, so we would have to pay. I read loads about boilers before having ours replaced. Viessmann seemed the best but I'm disappointed. I wish we had picked a Worcester instead.

Excellent prompt service so far

great product difficult to get technical advice have to call customer services first pretending you need a part then get transferred to technical and wait a long time for call to be answered as this is the same number for installers Please add customer technical helpline 9or add option to automated options) as often it is a relatively easy fix

Recently installed Vitodans 100-W. Basic installation went well but difficulty getting linked to internet and outside temp sensor had wrong values. Viessmann attended quickly and identified the problems. Outside temp sensor supplied was not correct part number and comms card was defective. Comms card was rectified on the spot and temp sensor arrived following day. Impressive service recovery. Once up and running operation has been faultless.

It's not until you get a new boiler that you realise how bad your old one was. Our new Viessmann is not only much quieter but it's also much quicker at heating the water and our radiators also feel much warmer too.

Good quality boiler and usable app.

After phone calling for more than a week someone has finally got in touch with me and an appointment has been made for an engineer to come over and fix the issue with my boiler. Happy with the engineer work who sort out the problem in less than 15 minutes, but very poor services in regards with contacting me for an appointment so because of this i wasn’t able to use the hot water in my house for almost 2 weeks.
