Review for Vaillant by Plumb Gas & Heat Ltd18th March 2022
Vaillant used to the the best brand to fit. But over the years they have gone down hill. All there boilers including the manufacturers they brought out all look the same. Our rep is the one whom is looking after us, hence why we fit a few. We only rate the 800 series.
They need to get there boilers back on top.

Review for Vaillant by BP Clews Energy Services24th February 2021
Good range of boilers,the pure range is a good price point. Two sets of filters,one is smaller if room is tight. Always found customer service excellent for warranty repair or technical help.
Review for Vaillant by SD Gas Servise22nd February 2021
The Vaillant EcoTEC Pro combi boilers are compact boilers that will not take up too much room on your wall. Its compact design and quiet performance are both purposefully engineered so that it melts into the background and you barely realise that it is there.
Review for Vaillant by JWP & Sons Gas22nd February 2021
Brilliant boilers. Easy to use, easy to diagnose on. Technical are very good and customer services are always on point. Only downside is the pcbs like to fault a lot.

Review for Vaillant by KS3 Installations Ltd31st January 2021
Just started fitting ecofit pure great value for a vaillant, if it could be a little cheaper I would push to customers a bit more but £889+ vat deal is pretty good in fairness never had an issue with the boiler it’s self and very easy to install and set up is ok once you read the manual and get used to the codes
Review for Vaillant by LM&D Builders28th January 2021
Have a propane gas on demand hot water heater, finding the appropriate jets was easy as was fitting, servicing is a dream, I don't think I will need another boiler in my lifetime or the next ( probably going to be hot enough there)
Review for Vaillant by XK8 Group27th January 2021
Good reliable boilers I always recommend never had any problem with them before and the support provided by vaillant is unbeatable compared to some others
Review for Vaillant by MHC26th January 2021
Have always recommended this brand for boilers. Whenever I am refitting a house we spec this. Not cheap but always reliable. I’ve had to call them a few times and always received good help. A known household name so the customer feels assured too

Review for Vaillant by Concannon Heating Services12th November 2020
Vaillant have become a very expensive brand that are driving both engineers and customers away.
Spoke to them about a boiler part and despite having it int here factory just 10 miles away we had to wait for 5 days lead time while it was shipped into the country form abroad.
The part was 3 times what what expected too. Customer services not willing to help.
Technical side of thing is top notch and always get a diagnostic. Just a shame about the prices.

We install these boilers regularly. Vaillant are the boiler brand we recommend to all of our customers. The build quality is great and I have never had an issue when it comes to customer service. They look after their installers and customers.
Review for Vaillant by N Bowhay4th October 2020
Vaillant boilers for me are the number 1 boiler for reliability, user operation and are easier to carry out service and maintained work. Customer service and technical helplines have never let me down when needed.
Review for Vaillant by D Stokes Heating & Plumbing1st October 2020
They are one of the more expensive boilers on the market but they are a good quality build and they do last for ages easy to repair and install
Review for Vaillant by Get Home Improvements28th September 2020
I have a valiant boiler 28kw installed by British Gas about 8 years ago but it’s an eco and for my house, at least 32kw should have been the minimum.
My boiler gets serviced every year but my local boiler inspector and he says that they can be a good make, just maybe not this model for the size of the house. I only have 3 bedrooms and 1 bathroom but it sometimes struggles to get enough pressure to get it to the bath.
My previous System seemed to work better for pressure and I probably would think that a larger kw boiler may be better but not mine.
Review for Vaillant by Tim Dean Plumbing And Heating Solutions Ltd27th September 2020
Quality boilers, easy to install and repair. Boiler status codes make fault finding easy. Vaillant controls are also easy to use and install.

Review for Vaillant by Gas Patrol10th October 2019
Vaillant is by far the most superior brand on the market.

Review for Vaillant by Pete Mayne Services8th March 2019
Just fitted my first Vaillant, Ecofit pure 625 with a VR70 and a VRC700. Feels a quality product. The VRC700 takes some setting up which is not very well explained in the manual, so required help from tech guys. They are very good and very helpful. I have been on a couple of training courses at their training centre in Bristol which are good.
Review for Vaillant by B N PLUMBING27th February 2019
I use vaillant boilers for my larger installs. Great boilers that cope with a lot. The displays are great and storing fault codes is a great feature that all boilers should have

Review for Vaillant by Gas Eco Heat3rd November 2018
Really like Vaillant boilers and I think they one of best on the market in my opinion.
Customer service requires improvement but other then that really good brand and great rewards for installers.
Review for Vaillant by Bitz 'n' PC'z Ltd5th October 2018
A very innovative, forward thinking company to deal with. The installer is at the heart of this and their excellent products are supported by a great team in Belper. I'm not a heating engineer, but do have dealings with Vaillant and use their boiler and ambisense kit in my own home.
Review for Vaillant by Gasrite1st July 2018
Vaillant have always been at the forefront of innovation and quality products and have always been my number one choice for boiler and heating products.
Review for Vaillant by Andrew Vaughan Davies Ltd28th March 2018
My favourite boiler and will continue to install if the standards are keep high.Eco Tec Plus range are second to none. The boiler operation noise is so quiet my customers can’t believe it’s working.
Review for Vaillant by The Boiler Change Experts29th November 2017
So far so good. Not had any problems getting vaillant on the phone or having them come out. They do like to see the installer go first when there is an issue though, which is sometimes not practicle.
Review for Vaillant by A1 Complete Plumbing & Heating Ltd28th June 2017
Best boilers on the market. I have been fitting these boilers for 12 years, great value for money, after sales second to none, option for extending warranty to suit customer requirements a great feature on what I consider the best overall package out there. The new Ecofit Pure is a fantastic product. The only reservation I have is the VSmart controller.
Review for Vaillant by CSO Heating LTD15th June 2017
I've been installing Vaillant boilers since 2008 and up until now I've never been called back to one or had to call Vaillant out under warranty. Vaillant are by far the best domestic boilers in the market.
