The Viessmann 050-W Is ideal for both new builds and any home renovations.

Stainless Steel Heat Exchangers: 

Viessmann 050-w Stainless Steel Exchanger

Like the aforementioned comparison to BMW, Viessmann, a fellow German brand, engineered their 050-W boiler to last.

Even though this is considered a budget boiler, the stainless steel heat exchanger is far more robust than other, higher priced brands. 

This might not mean anything to you as a consumer, however take our word for it when we say that the heat exchanger is a likely fault point in any broken boiler, making the reliability and chance of breakdown in our Viessmann boilers far less likely. 

This gives you peace of mind that your boiler , even at a budget, will remain in working order for years to come.

That’s why Viessmann is an award winning, and continuously upcoming boiler brand, quickly catching up to the likes of Worcester Bosch, et al.

Is the Viessmann Vitodens 050-W really the best choice compared to the Worcester Bosch Greenstar 25-i?

Viessmann Boilers

Absolutely! To start, the Viessmann 050-W boiler has a water flow rate at 12 litres/min whereas the Worcester-Bosch Greenstar has a flow rate of 10 litres/min. 

Also, the heat exchanger on Viessman being stainless steel makes it a much better choice when compared to the Worcester-Bosch’s Aluminium exchanger and with 98% efficiency compared to the Worcester-Bosch’s 94%.

It really is a no-brainer when it comes to budget boilers for 1, 2, and 3 bedroom homes. 

Other benefits of the Viessmann 050-W range:

Guess what? It just seems to get better when it comes to the Vitodens 050-w.

The electronic boiler control unit for thermostatic/weather compensated mode is already included and integrated into the Vitodens 050-W. Oh, as well as a frost stat! 

Coupled with it already being particularly low noise when in full operation and a compact, eye catching design, the Vitodens 050-W is among the best combi boilers and of the smallest wall mounted boilers available on the market today. 

It’s even perfect for multi level buildings and flats, being able to have 5 boilers connected to a vertical flue system over several floors. 

It’s low installed height makes it easier for replacement of old boilers, with improved access to serviceable parts such as the plate heat exchanger and inherent ease of wiring with all Viessmann boilers make it easy for your annual boiler service to be performed.
