Very happy with this condensing boiler and the qualified fitter William Davidson. Five stars all round 👍
Helpful Report
Very impressed with my new boiler so far. Had not heard of Viessman before but will certainly recommend to family and friends.
Helpful Report
Technical Support answered questions promptly and the boiler has so far performed well for the first 10 months and gas consumption is considerably reduced.

Great advice on Viessmann from our heating engineer & a very efficient installation. It’s great to have heat & hot water when it’s -4C outside
Helpful Report
My heating system packed up just as the cold spell was beginning. Despite three visits from my trusted installer, Tony, the fault couldn't be traced. It didn't seem to be the boiler or the thermostat, a new pump was fitted, a new valve and still the heating came on at random times for an hour or two, usually in the middle of the night. Finally, all options exhausted, Tony decided to call in a Veissman engineer. Gareth was brilliant. I was his last call of the day. He determined, after a thorough examination, that it wasn't the boiler, and although it was past his allocated time slot, he stayed on and tested other components of the system - and finally found in fault in the new valve that that been fitted. It was replaced the next day and everything is working perfectly. So two big brownie points for Veissman - the problem wasn't the boiler, which was working perfectly, and the engineer Gareth acted helpfully and successfully to find the real fault.

Did not satisfactorily answer my question regarding the Flow Sensor or what further measures could be taken to satisfy my enquiry. Just because an error is not shown does not necessarily mean the boiler is operating at its optimum design specification.

had a new boiler installed - which broke down after 10 hours. only sent an engineer after making a fuss. Engineer did a great job and fixed boiler next day. Quality control needs looking at as boiler had a gas leak when delivered - which was fixed by the installer. Two faults on a premium product unacceptable. The chosen installer was outstanding and would recommend installer unreservedly.

I have a vitodens 100 boiler and it seems as though the Vitodens team is loath to help you if you need technical advice. My boiler is not that economic so whats with all th BS about cutting fuel bills in half etc. Technicians who have serviced my boiler also comment on the lack of help from the Vitodens team. Viessman also make the most complicated timing/temperature control known to man. I am computer savvy and find it difficult. Peter Lonsdale

Replaced an old Potterton boiler with a Vitodens 100-W Combi 5 years ago, best thing I've ever done, and its now payed for itself. It's been running like a dream, halved my gas bill and electricity bill dropped by about 30% with the high efficiency pump. A lot of these reviews on here reflect the quality of installation, and not the boiler manufacturer, so always use a Viessmann Trained Installer, that's my little piece of advice.

Only had the boiler 5 years then we had no heating and no hot water we had a new circuit board put in and a few weeks later same problem Gas man came out said it was our new circuit board? 21/12/18 (cost £400) waited two weeks as it was the festive season (not the best time to be without hot water or heating and we are both pensioners) phoned gas man, said he got in touch with Viessman and they are going to sort it out (03/01/19) still waiting?

In comparison with the competitive companies I considered Viessmann have been very professional, prompt and thorough. The response time for answers to my queries during the process has been exempliary. The equipment looks good and is very quiet. If the boiler performs as well as the people behind it I can foresee little or no problems,

I was told 2 years ago how good Viessmann boilers were. But of course every plumber has a favourite. However, more than one plumber told us about Viessmann, so we went ahead. For 2 years the boiler has been absolutely fantastic. We went for a Combi boiler, which did away with the hot water cylinder system. Great. Here comes the however. Oh!! I here you say. On Christmas eve the boiler did not come on first thing in the morning. Oh No!!! Contacted my plumber and he came out and suspected that the PCB was faulty. As the unit was covered by a 5 year warranty, he contacted Viessmann support team. This was around 9am and at 11am the Viessmann engineer was knocking on my door. Boiler was fixed before 12 noon. Things do go wrong with equipment, but if I can get service like that, I don't care. I would rather buy a product from a company with a good back up service, rather someone who does not consider the second sale or whether they will get recommended. I would 100% recommend Viessmann. Well done.
