Viessmann UK reviews

Having installed Viessmann boilers for well over 15 years, I can fully endorse them as boilers of superior quality and technology over other brands. The interface and build quality are superb and the heat exchanger, in my opinion, is the …

Have been installing Viessmann boilers for around 18 months now and the quality is very good. They are a brilliant modern boiler which have easy solutions to make the boiler run efficiently. The backup could be slightly better ( i am lucky …

I Have been installing Viessmann boilers for 15 years and I can honestly say the boilers have been very reliable for my customers. Viessmann offer a wide range of quality products to produce your heating and hot water needs. There new wifi …

We have used Viessmann Boilers for over 13 years to supply our customers with a top quality product which is reliable well made and back up is second to none. With our customer base reaching 4000 we need to install a product we can say with …

We bought our house 2 years ago which had a viessmann boiler in. The boiler started to malfunction (December 2022) we had no heating and no hot water. We rung this company up informing them of this we also have small children in the home. …

We had a Viessmann VItodens 111 boiler that had so many problems, these German boilers are supposed to be so good but waiting on parts can take several days. Their engineer visit under the warranty is sometimes hopeless, I’ve been left …

Weissmann were professional, knowledgeable and advised the most suitable boiler for my home. The wait time was very short.

I’ve had my Viessmann boiler for two years now, and to date it hasn’t missed a beat. Significantly quieter than the prematurely expired boiler (another brand) that it replaced.

Impossible to book a service to comply with the warranty conditions. UK after care is in meltdown it seems. There’s no option on the phone line to book a service anymore, you have to fill in an online form and wait for them to contact you. …

Viessmann are the best boiler manufacturers in Europe. If it’s gas boilers or heat pumps they have a solution to any situation. I had a boiler in a basement and Viessmann made me a vertical flue that fitted inside the existing chimney. It’s proper engineering and extremely reliable

Quality products, with reliable professional company support – I will not use any other boiler manufacture I will only fit Viessmann. After 40 years in the business and having used other manufacturers’ products I have found Viessmann to be …

My fitting people left with no hot water working. They said the brand new boiler has a faulty component and need me to contact customer service myself. Viessmann’s line is always busy and I cannot get hold of anyone.

We wanted to install a heat pump from Viesmann. We have sent a request to Viesmann and they emailed us that their installer will contact us. The installer Eco green contacted us and we signed the contract. We payed 2 portions ( around …

Don’t be fooled by associating the German name with reliability. I have had problem after problem with my boiler (and so have my parents). The customer service is utterly dreadful. I would change boilers just on the basis of the customer service if I could afford to.

Top products and service, one of our go to brands depending on installation budget.

As an installer I have fitted many different boilers , viessmann boilers are by far the best out there, google stainless steel vs aluminium heat exchangers and you see stainless steel performs and last longer than aluminium . Viessmann after care is also great for customers piece of mind.

Bought a Vitodens 111-w. Failed when plumber started commissioning. 3 days without heating or water. In December. 4 parts replaced and 2 more on order. Told by customer services to “make do” over the weekend with temperatures between 3c and …

Biggest mistake ever to go for a viessmann boiler, I paid extra money for an extended warranty. I been trying to contact them for a few weeks over the phone and email but no response, I noticed that must of the customers who try to contact them have the same issue.

We’ve been fitting Viessmann gas boilers for over 6 years and always found then to be very reliable and packed with energy saving tech like Weather compensation and class leading modulation rates.

We (Plumbfaster.co.uk) have been repairing and and installing Viessmann Vitodens boilers for the last 15 years, their products are second to none in the domestic and commercial marketplace . Customer service is very good as is both their on …

Bought a new boiler 2 months ago, it broke down and we have no hot water for the last 10 days. Contacted them on the 29th of Octover. 10 days later still no repair done no help and almost rude attitude when complaining. AVOID THIS COMPANY!

Awful company, booked in for fixed price service & repair on a Vitodens 200-W, £360+VAT upfront, had no hot water and a leak on condensate pipe, Engineer turned up & straight away said he’s not fixing the leak, at no point when booking in …

Good Boilers
They are the worst company for customer services, i’ve been fitting these boilers for 15 years. …

Worst company EVER, we had the misfortune to buy veissman vitodense 100 boiler in 2010 with the boiler scrapage scheme from the govt. and it hasn’t worked properly since then we have had 3 new time clocks and loads of washers. Viessman sent …

World class service!!

Our experience of Viessmann went beyond any level of customer service that we …

First class service and product!
The staff are always willing to help to the best of their ability…which is a rarity in these strange/struggling times.

I have fitted 160+ of your boilers over the last 8 years and find them very efficient and extremely reliable, I very rarely fit anything else.

Boilers, heat pumps and all renewables. Great company with fantastic products

We have found the boiler to be okay although not particularly reliable. The major problem is Viessman themselves as the customer service is probably the worst of any manufacturer. My 80yr old,disabled father in law had a breakdown of his …

We had a Veissman boiler fitted in February 2022. Last week we had no hot water. This is concerning so soon after installation but what makes it worse is I’ve had to chase and chase making call after call -terrible holding times – to get …

We have used their products for over a decade now and have very few issues ever with quality and service. Our go to boilers of choice.

My new Boiler broke on Tuesday couldn’t get through to report repair after 1 half hours of trying on the phone so sent an email. Rang out of hours team told I would be called back no one did. Tried all Wednesday to get through to them …

I’ve been working with Viessmann since 2005 supporting them with service , maintenance and installations – They are our go to boiler because of their reliability , efficiency and value for money

Quality boiler never stops plenty of hot water very reliable and economical

Really good Boiler. After sales service is exemplary. I had a problem within the 5 year warranty, no hot water. I called on Friday morning, really efficient and friendly Customer Service, who arranged call out for Monday , mulch speedier …

I chose this brand because they are supposed to be the best boilers. They are not a cheap option. Just after two years I have been told the pump has failed.
48 hours later I am still waiting for an engineer to turn up. Seriously in impressed and cold!

Boiler was supplied with a broken part on a Monday. Plumber made it very clear which part was broken. Viessman engineer showed up without part. After phone calls to Veissman they took till 4pm to inform us they couldn’t get the part that …

Viessmann make outstanding boilers. We have fitted hundreds of them and use them in our own homes, and time and again find them to be superior to any others for use in small and large domestic installations. We have no hesitation in recommending them to all our clients

Have been a Viessmann installer for many years now and I still consider them the best boiler on the market at this time.

I’ve a V 50 and had it for 4 years, just had first fault with it but fortunately it’s got a 10 year warranty 🥰. Called Viessman who booked an engineer next workung day who turned up bang on time and resolved the problem right away. …

How can you trust a company that after 3 letters, 7 phone calls they can not supply a simple Warranty confirmation. I purchased in May 2017 a boiler with a 10 year warranty. I paid the extra for a ten year warranty and still nothing other …

Bought a Viessmann assuming it would be a reliable solid boiler based on consumer reviews and reccomendations. The plumber was very pleasant and professional and did a very tidy install. However after only a matter of months and the first …

Largest boiler manufacturer in the northern hemisphere state of the art technology with ecological and economical TCO appliances

Appalling customer services. Unreliable boiler, no support offered to extremely ill customer. Left without heating or hot water in the middle of January. I would not recommend this company.

Please avoid viessmann boiler like plaque. I order vitodens 200w 30kW. They sent me 200w 25kW and they said it’s the same. And point out on instruction book on page 120 and it’s running from 1.7 to 31.1. so it’s 30kW. That’s the most …

As an approved partner for the past 6 years or so I have been very impressed with the quality of the product, I now fit nothing else, and on the rare occasion I’ve needed technical/warranty back up the response has been very quick. Highly recommended by an engineer with a choice.

Really really disappointed with viessmann
Had a booking to repair a boiler under warranty
And the guy refusing to do the job because no parking directly outside the house …

As an installer I have found Viessmann products to be extremely reliable. A note on Timothy Bamfords pictures. In my experience hose failure like this is due to flushing chemicals being left in the system, all traces of these chemicals …

We as a company has been installing Viessmann boilers for around about 8 years now. Viessmann is a brand I trust. In fact this is the brand I have installed and my own house and also my parents.

Unfriendly & unhelpful customer service. Almost new boiler not working and a “whatever” attitude from the tech support & CS people. The experience was similar to interacting with very stroppy teenagers, bizarrely unprofessional Kevin & …

Fantastic company offering a great variety of products to cover every heating requirement for the UK market. Best boilers on he market for gas, oil and LPG with superior customer services and back up.

I can’t rate Viessmann enough. Soild boilers i personally think they are better than Worcester and Vaillant. My main line of work is boiler repairs and i seem to repair whey more Vaillants and Worcesters than Viessmann. AND they are cheaper.

A**** customer service
Highly recommended …

Best boilers on the market, great customer service
Made by an engineer for engineers

Very poor on technical helpline. Was told on several occasions that would call back but never did. We were then force to ask Viessman to attend. They were there for a very short period of time and charged over £400! …

I have been asking Viesmann to find an installer to fit a Viesmann gas boiler for me now for over 3 months and they still can not find one it seams they have a good product but no installers in North Wales I think they will have to get …

Recommended by a friend, happy with the price and the installer was great. 12 months trouble free, a constantly warm house and cheaper Bill’s.

best boiler on the market! as an accredited installer for vaillant, worcester bosch and viessmann, I can honestly say viessmann beats the competition hands down every time!

Great boilers and great back up, we have installed over 100 Viessmann boilers and can honestly say they are the best boilers we have ever installed.
