Controls & Features of the Viessmann Vitodens 050-W

The great news is that when you purchase your Viessmann boiler with Heatable, you will receive a 10-year warranty. This beats the standard warranty length of 7 years and is extremely generous for an entry-level unit.

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.

These features combined earned the Viessmann Vitodens 050-W 29kW a thoroughly well deserved, ‘Which? Best-Buy’ award.

A much sought after award in the home improvement sector – the prestigious ‘Which? Best-Buy’ indicates true quality and value to consumers through the independent adjudicators, Which?

The only reason you shouldn’t be buying a Viessmann Vitodens 050-W is if you’re deciding to treat yourself to the – somehow – more impressive, Viessmann Vitodens 100-W.

A look at the Vitodens 050 Vs. a popular competitor, the Worcester Bosch Greenstar i

  Worcester-Bosch Greenstar 25i Viessmann Vitodens 050-W 29kW

Hot Water Flow Rate 10 Litres per min. 12 Litres per min.

Price range (installed) £1,845 - £2,200 £1,795 fixed with Heatable*

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

So who's the winner - Viessmann or Worcester Bosch? 

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.

In comparison, Worcester Bosch is well-established in the UK, so availability of parts is extremely reliable.  Their support and aftercare are also extremely well-rated, as is clear from their impeccable TrustPilot reviews.
