■ New build- prefabricated houses and developer projects: Installation in utility rooms and attics The Vitodens 111-W is the ideal product, particularly in new build, as it can be installed before the screed is put down. ■ High DHW convenience due to loading system and integral stainless steel loading cylinder (46 l capacity) Recommendation for application ■ Control unit for constant temperature and weather-compensated operation ■ Simple and innovative operation via control unit with touchscreen ■ Modulating MatriX cylinder burner with a long service life

■ Durable and efficient thanks to the Inox-Radial heat exchanger You have been forewarned, if it is a KM bus control, you may live to regret specifying it.■ Particularly space-efficient gas condensing boiler with integral stainless steel loading cylinder ■ Standard seasonal efficiency of up to 98 % (Hs ) When the thing's not doing what you want at 4pm on Xmas Eve, I don't want to answer the phone and Viessmann will have gone home. We aren't the end user - and they don't get a course. Yes, we can understand them once we've been on their course, but one has to bear in mind we just fit them. Worth saying that the colour display on the 300 will be almost impossible to understand, there is someone in Viessmann who only signs off controls once they have been rendered unfathomable. You can go to a house with priceless antiques, Wilton carpets and a Bentley in the drive for the au pair, but they won't want to spend a penny more on the boiler room.Ĭonversely, the 100 series Viessmann range was never sold in Germany because they thought the cheap construction would damage the brand. The main reason the previous 300 series was dropped for our market was because we are very price sensitive in the UK on boilers. The testing regime in the UK is such that it costs a small fortune to get approvals for each model derivative. If you look at Vaillant, Bosch etc they all sell different, arguably more interesting, products in Germany but comparisons are pointless, because it is down to their UK product management team what comes over here. No idea, what Viessmann are knocking out in other markets is an irrelevence to a UK installer.
