Review for Viessmann Vitodens 100-W by CHEFTEC Ltd25th February 2021
Well engineered boiler with a stainless steel heat exchanger & very easy to use controls.
Clearly made with an installer / heating engineer in mind for ease of installation , servicing & onward repair. Combined with a 12 year warranty , what’s not to like?

Review for Viessmann Vitodens 100-W by BSL Plumbing & Heating18th October 2019
Surely the most outstanding ‘entry level’ boiler in the world of heating. The 050-W is the perfect combi for 1-2 bathroom homes. Through Heatable, the Vitodens 050-W can be acquired with an exclusive 10-year warranty at a staggeringly low price. Viessmann have described sales of the Vitodens 050 as similar to that of Range Rover sales to wealthy urban mothers.
Review for Viessmann Vitodens 100-W by Southdowns Mechanical2nd January 2019
My top of the range boiler when I'm quoting multiple boilers.
Well built solid boiler with a large bore main heat exchanger , could do with a cover to hide the controls but thats my only criticism
Review for Viessmann Vitodens 100-W by Wakefield Boiler Services29th December 2018
The only heat only on the market that I now install, I have full confidence in this boiler. Stainless steel single but very large coil heat exchanger. A simple and a dream to service very year that it’s quite enjoyable doing it. Features are good for a heat only boiler, great display with good info. As stated above all of the product is very good so bang for your buck is very good.
Review for Viessmann Vitodens 100-W by BPH - Blakemore Plumbing And Heating9th December 2018
My preferred choice of boiler. Great built quality, even with the rubber hoses, I actually preferred them. Can be stripped down in 30 mins. The customer support is brilliant. The Viessmann Direct shop is great for all spares and boilers. Plumbase also stock spares now. Fitted 15 this year including 2x 200ws and my first 222f. The 200 range is by far the best thing on the uk market.

Review for Viessmann Vitodens 100-W by Norwich Heating Services16th October 2018
I’m a Viessmann installer so maybe I’m biased but...
Combined pressure relief and condensate.
Impressive boiler with great support.
Great product range.
Not everything is amazing with these boilers and things do go wrong but I would prefer to fit these boilers every time.
Review for Viessmann Vitodens 100-W by Thames Gateway Safe Gas Renewables Ltd6th January 2018
Fantastic boiler, highly recommend. Easiest boiler to work on, given the choice I would fit this boiler every time. Also look at the 200 range as the top end of all boilers.
Review for Viessmann Vitodens 100-W by Ickenham Heating Limited22nd December 2017
Great boiler, looks like a bit of a fridge on the wall but nice to work on. Now that they have updated from rubber pipes inside the quality is great. Bit of an issue sourcing parts.

Review for Viessmann Vitodens 100-W by Nick Keeble and Son27th August 2017
Most solidly built open vent on the market. Instructions aren't great for commissioning etc but once you've been on the training it's easier
Review for Viessmann Vitodens 100-W by Elements Heating Installations1st July 2017
This is worth spending the extra money over other brands. Looked after this boiler will run for years. From a maintenance point this is cheap to keep on top of. Very small and easy to fit and use.
