Viessmann Vitodens 050 Boiler Review

Viessmann Vitodens 050-W Boiler Review

The Vitodens 050-W is Viessmann’s flagship budget gas boiler range. It comes with all the main advantages of any other Viessmann boiler, such as a stainless steel heat exchanger and high energy efficiency, but at a low, low price.

A Vitodens 050-W boiler comes with DHW output ratings from 5.9 to 29.6 kW.

The truth is, this model will do a good job in most properties, as it’s quiet, ultra-compact, and its energy-efficient design is exactly what most homeowners are looking for.

Key Benefits of the Viessmann 050-W

Below, we’ll highlight some of the most essential benefits of 050-W model:

  • Low price
  • Compact size
  • Inox Radial Stainless steel heat exchanger
  • Efficiency rating of up to 97%
  • Low CO2 emissions
  • Integral instantaneous water heater
  • Digital LCD Interface
  • Which? Best Buy Award
  • Extended warranties available

Viessmann 050-W: Useful Features

Some of the features listed below are unique, whilst others are common among all top-shelf boiler brands.

That said, each of these features is highly useful in its own way. For a budget boiler, you’ll find that the Viessmann 050-W has plenty of handy functions.

Ultra-Durable Stainless Steel Heat Exchanger

The Vitodens 050-W comes with a high-quality stainless steel Inox-Radial heat exchanger. This component efficiently transfers heat to water while keeping natural gas use to a minimum.

The materiality is a key feature here, as stainless steel heat exchanges typically last longer than aluminium ones. This means that Viessmann’s heat exchanger should last a long time without developing defects.

Shock Arrester for Quiet Operation

All boilers can produce some degree of operating noise, but those fitted with a shock arrester are generally far quieter than others.

The Vitodens 050-W comes with a shock arrester fitted as standard; this is not the case with most of its competitors.

High Energy Efficiency to Save Money On Your Energy Bills

Depending on the size of the boiler you choose, a Vitodens 050-W boiler can offer an energy efficiency rating of up to 97%. This is a hugely impressive number for a gas combi boiler and almost comparable to some electric boilers.

Integral Instantaneous Water Heater

This component allows the Vitodens 050-W to produce almost instantaneous hot water on demand.

With a flow rate of 12 litres per minute (your mains typically offers 9 litres a minute), this means you shouldn’t find yourself running out of hot water.

Low CO2 Emissions = Lower Carbon Footprint

The Vitodens 050-W has some of the lowest CO2 emissions of any gas combination boiler. So, if you want to be green but can’t afford the more expensive eco-friendly combi boiler alternatives, a Vitodens 050-W is a great choice.

User-Friendly Digital Interface with LCD Display

Vitodens 050-W display

The Viessmann Vitodens 050-W comes with a digital user interface that is displayed on a bright LCD display. This display helps make this combi boiler extremely easy to use.

Compact Size Helps You Conserve Precious Space

At just 707mm high, the Vitodens 050-W is one of the most compact combi boilers around and therefore easy to hide inside a kitchen cupboard, under the stairs, or anywhere else.

If you’d like to maximise living space at home, this combi boiler is an excellent option.

Weather Compensation to Save UP to 15% on Fuel Bills

The weather compensation feature helps Viessmann 050-W by adjusting the boiler’s operation — and fuel use — to the outdoor weather.

Viessmann Vitodens 050-W Warranty

The length of the warranty offered on a boiler is an indicator of its quality  and how long the manufacturer expects it to last without major repairs. If your boiler only has a one-year warranty, it’s unlikely to keep going for a decade or more.

The Viessmann Vitodens 050-W boiler is sold with a 3-year warranty as standard, but Viessmann also offers an extended warranty offer that lets you stretch this to 7 years.

How to Get a 10-Year Warranty

However, if you buy through Heatable, you’ll be entitled to their exclusive 10-year warranty. This way, if anything goes wrong with your Viessmann Vitodens 050 boiler within the next decade, Viessmann will either repair it for free or replace your boiler.

And 10 years is a very generous warranty period for a boiler.

Viessmann 050-W Energy Efficiency

The Viessmann Vitodens 050-W boilers all come with the top class A-rating for energy efficiency.

Depending on the size of the combi boiler you opt for, they can offer energy efficiency ratings of up to 97%. This is extremely high for a gas condensing boiler and highlights the high-quality German engineering that has gone into this unit.

Viessmann Vitodens 050-W Controls

The Viessmann Vitodens 050-W comes with a digital user interface with LCD display. This makes programming your boiler and controlling it much easier than some other models with less user-friendly controls.

Thermostat Compatibility

The Vitodens 050-W is also compatible with all the major smart thermostats and control units that are currently on the market in the UK. If you want to go for a high-tech control unit with your new Viessmann’s boiler, the Vitodens 050-W will let you.

Viessmann Vitodens 050-W Installation Costs

The cost of installing a Viessmann Vitodens 050-W boiler will vary depending on where you buy it. Different installers will source their boilers from different places and at different prices, which is why the price difference can amount to hundreds of pounds.

Factors That Drive Up Installation Costs

Certain variables will include what other work you need to have done. For example, if your pipework needs repairing, you need new radiators, or you’re planning to move your boiler, your installation costs will likely rise.

We would always recommend that you get a minimum of three different quotes before choosing the right combi boiler for you, and ideally more. It is a good idea to approach at least one nationwide installer, one local tradesperson, and one online installation company.

Vitodens 050-W vs Worcester Bosch Greenstar 4000

Viessmann 050-W vs Worcester Greenstar 4000 — Features

The Viessmann Vitodens 050-W has a stainless steel heat exchanger, while the Greenstar has an aluminium one; aluminium heat exchangers tend to be more susceptible to wear-and-tear.

It also comes with a shock arrester included as standard, whilst the Greenstar doesn’t. And while the Vitodens offers up to 97% energy efficiency, the Greenstar can only get as high as 94%.

The Greenstar also only offers a 10 litre per minute hot water flow rate, while the Vitodens 050-W offers 12 litres per minutes.

Viessmann Vitodens 050-W vs Worcester Bosch Greenstar — Prices

However, perhaps the biggest difference is the price. You can generally get a Vitodens 050-W installed for around £2,000, whereas the Worcester Bosch Greenstar 4000 will cost anything between £2,200 to £2,500 (inc VAT), depending on where you buy it from.

In other words, the Viessmann 050-W is a better combi boiler in many areas, and may be available at a lower price.

FAQs About Viessmann Vitodens 050-W Boilers

As we conclude, we’ll take a few minutes to answer some pressing queries about Viessmann Vitodens boilers.

What kW is a Vitodens 050 W?

The Viessmann Vitodens 050-W combi boiler range has 2 models: the 25kW and the 30kW combis.

The Vitodens 050-W 30kW (occasionally referred to as the Vitodens 050-W 29kW), has a domestic hot water heat output of 29.6kW, whilst the central heating output ranges between 3.2kW and 25kW.

Meanwhile, the 050-W 25kW offers a DHW output of 25.4kW and a central heating output of 3.2-19.0kW.

How do I reset my Viessmann Vitodens 050-W?

To reset a Viessmann Vitodens 050-W boiler, you have to press the “OK” and “MODE” buttons at the same time, and hold them down for 2 seconds.

Once you see 3 lines emerge on the display screen, you’ll know that the reset sequence has begun. The boiler should reset quickly but may take several minutes, so you’ll have to be patient.

Note that simply resetting a boiler whenever a fault shows up will not resolve the boiler problem behind the fault.

For instance, your Viessmann may lock out because the pressure is either too low or too high.

Or, if the temperature sensor fails, the boiler’s PCB may erroneously conclude that the temperature is too high and shut the boiler down as a precaution.

The fault codes your boiler display should help you diagnose the exact problem.

Depending on the error code, you may need to get a Gas Safe engineer to help you fix the issue before you reset the appliance.

Are Viessmann boilers made in Germany?

Viessmann are headquartered in Germany, but the boilers are not necessarily manufactured there. Viessmann has production facilities in 10+ countries worldwide, including the UK.

How do I increase the pressure on my Viessmann boiler?

To increase water pressure on a Viessmann Vitodens 050-W combi boiler, you’ll have to use the external filling loop, which may look different depending on the year your Vitodens 050-W was produced.

Regardless of the configuration, there will be 2 valves; first, you should open the valve on the mains water pipe. Second, you’ll slowly open the “inlet” valve and you’ll hear the water rushing in.

While the system is getting topped up, keep an eye on the pressure gauge. Once you see that the needle has moved over 1 bar, you can close the valves — your boiler has now been refilled. If your boiler was locked out prior to the procedure, you’ll want to reset it at this point.

Now, this is important — if your boiler is consistently losing pressure, there’s likely a leak somewhere in your central heating system (or the boiler itself). If this is the case, you’ll have to repair the leak before you top up the boiler.

What property size is a Vitodens 050-W suitable for?

A Vitodens 050-W can be used in a property with up to 3 bedrooms and 10 radiators which means that it will work for most family homes.

However, as a compact, budget boiler, the Viessmann Vitodens 050-W boiler is best suited for smaller properties. According to Viessmann themselves, it’s ideally suited for new-build homes or replacing older boilers.

If your home is on the bigger side, or you have a high demand for hot water, you should opt for a larger, more powerful Viessmann boiler.
