Viessmann Vitodens 050-W Review: German engineering for your hair home

Blue jeans, morphine and anti-tank grenades – excluding food, there isn’t much that German pioneers haven’t achieved and excelled at. There’s a high chance you’re driving one of their cars - or want to.

The Viessmann Vitodens 050-w combination boiler 29kW is no exception to their impossibly high standards.

A boiler is the sum of all its parts and it's these internal parts that have Viessmann picking up awards and acclaim like tenner’s off the floor.

Most notably, their high-end stainless steel heat exchanger.

...But what does that actually mean?

Viessmann Vitodens 050 Heat Exchanger

Put simply, if a boiler breaks down or fails entirely – it’s very likely to be the heat exchanger inside.

Other boilers within the Viessmann’s price range tend to construct their heat exchanger from aluminium, chocolate or good intentions which inevitably leads to its downfall.

The stainless steel exchanger of the Vitodens 050-W is sturdy and dependable like a thick white loaf, or your first Nokia.

A popular competitor to the Viessmann Vitodens 050-W is the Worcester-Bosch Greenstar 25i (and the Greenstar 30i).

A worthy adversary – but perhaps just in name only?

In terms of parts, warranty and price – the Viessmann Vitodens 050-w combination boiler is a clear winner and customer installation numbers are catching up on the Worcester Bosch faster than a rat up a drainpipe.

The Viessmann Vitodens 050 29kW has higher potential efficiency, a longer warranty, the all-important heat exchanger straight from the planet Krypton and a much more attractive price.

So why would Viessmann Vitoden offer a better boiler at a lower price?

Viessmann is already market leaders in commercial boilers and has a great hold on the European market but their endeavours into the domestic market of Britain are still in their infancy by comparison.

Their foothold in Europe has been attained through years of quality products – a standard they refuse to let slip domestically.

...Hence the stainless steel heat exchanger opposed their competitors’ made from sweet potato mash and poorly mixed gravy.

It’s this hunger from the manufacturer that you the consumer can and should take full advantage of.

In addition to this – Heatable proudly work closely with Viessmann in order to deliver the most competitive boiler replacement prices in the UK and the most streamlined installation service.
