Viessmann Vitodens 050-W 29kW Combi Gas boiler frequently asked questions

Viessmann Vitodens 050-W 29kW - a system boiler, regular boiler or combi boiler?

When looking for a combi boiler for your house or flat, the Viessmann Vitodens 050-W 29kW might be a suitable option for you.

In many properties, combi boilers are more suitable than traditional types of boiler. Combi boilers heat water instantly on demand, which they draw directly from the mains supply, removing the need for storage tanks that can take up valuable space in your home.

A combi boiler is often the right choice for a smaller property, particularly if your home doesn't have a useable loft. As water is heated and delivered immediately rather than being kept warm for hours in an immersion tank, combi boilers reduce gas usage, thereby minimising your heating costs.

The main disadvantage of combi boilers is that they can only heat a certain amount of water at any one time. This means that, if two people are using different taps or showers within your home at the same time, the flow of heated water to each will be reduced, as will the water pressure and temperature.

Should I install a Viessmann Vitodens 050-W 29kW combi boiler in my house or flat?

It's best to choose a boiler whose size or "output" is right for your home.

The more hot water and heat you want, the higher the output level of your boiler should be. Output is measured in kilowatts and it describes the maximum level of power your boiler has to heat water.

If your output level is too low, your boiler will not have the power it needs to get your water as hot as you want it, particularly when there's a lot of demand for it. Choose a boiler whose output level is too high and you'll have all the hot water you need but will be paying too much for it through higher gas bills.

Which types of property would this Viessmann Vitodens 050-W 29kW Combi boiler be appropriate for given its output of 29 kW?

An experienced heating engineer would recommend that the Viessmann Vitodens 050-W 29kW combi boiler is a suitable choice for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

Homeowners considering fitting a combi boiler to their home need to consider flow rates as well as output rates.

The flow rate is a measurement of the volume of water a combi can instantly heat and send to the taps and radiators around your home. The higher the likely demand for hot water in your home, the higher your combi's flow rate should be. This Viessmann Vitodens 050-W 29kW Combi boiler's flow rate is 12 L/m.

Unlike heat only or system boilers, combi boilers don't store hot water in a tank for later use - instead, they draw it directly from the mains. This means that the volume of water your boiler can actually process is constrained by the flow rate of water in the mains pipe.

So, if you choose a combi boiler with a 15l/m flow rate but the flow rate in your mains pipe is 12l/m, the combi boiler's working flow rate is also 12l/m.

Combi boilers are also not always the correct choice for homes with multiple bathrooms, a high number of radiators, or where more than one family member will want to use hot water at the same time.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


Making space for the Viessmann Vitodens 050-W 29kW

The Viessmann Vitodens 050-W 29kW is 707 mm tall, 400 mm wide, and 350 mm deep in size.

Viessmann Vitodens 050-W 29kW – condensing or non-condensing?

Condensing gas boilers like the Viessmann Vitodens 050-W 29kW are more energy-efficient and choosing one for your home will cut the amount you pay every year for your gas.

They do this by capturing the heat in water vapour condensation and in exhaust gases which would normally be expelled via the flue. They then recycle that heat, returning it to the system to, among other tasks, reheat colder water that is returning to your boiler from your radiators.

Is choosing the Viessmann Vitodens 050-W 29kW combi boiler environmentally friendly?

How we heat our homes and the damage this does to the environment has become a pressing concern for many homeowners worried about the effects and impact of climate change.

Nitrogen dioxide emissions in Britain's largest cities are at dangerous levels and this has been caused by gas boilers. In fact, 14% of the UK’s greenhouse gases are produced by central heating.

Would the environmental impact of installing a Viessmann Vitodens 050-W 29kW combi in your home be positive? Let's look at the numbers.

Boilers manufactured and installed in the UK are assigned energy efficiency ratings following testing to an agreed set of standards. These scores indicate how much energy the boiler uses and how much goes to waste when it's in operation.

By law, boilers must achieve a SEDBUK rating of "A" subject to achieving a minimum of 92% energy efficiency. Prior to April 2018, the minimum was 88% (88% and 89% on the SEDBUK are graded "B" and 90% and above is graded "A").

The Viessmann Vitodens 050-W 29kW was awarded an efficiency rating of 93% with a SEDBUK band rating of "A".

The ERP (or Energy Related Products Directive) is European legislation which applies to all products that consume energy throughout their lifetime.

Its purpose is to encourage manufacturers to offer products that are kinder to the environment by reducing harmful gas emissions at all stages, from production and end use right through to disposal.

The ERP rating for the Viessmann Vitodens 050-W 29kW is "A" for heat and "A" for water.

How long is the warranty period on the Viessmann Vitodens 050-W 29kW combi boiler?

The Viessmann Vitodens 050-W 29kW boiler comes with a 3 year warranty for parts and labour.

Viessmann Vitodens 050-W 29kW Combi Gas boiler frequently asked questions

Viessmann Vitodens 050-W 29kW - a combi boiler, system boiler or regular boiler?

The Viessmann Vitodens 050-W 29kW boiler is a combi boiler you may wish to consider when looking for a new boiler for your house or flat.

In the past, most boilers needed one or more storage tanks to operate - one to store warm water and the other for storing water to be heated later. But storage tanks are problematic in properties where space is at a premium and particularly where there is no loft. Many properties in the UK are small and so manufacturers introduced combi boilers in the 1970s to eliminate the need for tanks.

With a combi boiler, the hot water for your radiators and taps is delivered on demand. The boiler instantly heats water it draws directly from the mains internally. It then distributes the heated water around your home at mains pressure as you need it.

It is important to bear in mind that, while combi boilers have many benefits, they can only heat a certain volume of water at any given time. This means that, if you run a shower at the same time as someone else is doing the washing up in the kitchen, the volume of water passing to each point will drop, causing a fall in pressure.

Is a Viessmann Vitodens 050-W 29kW combi boiler right for my house or apartment?

It's best to choose a boiler whose size or "output" is right for your property. With a boiler, however, size does not mean how big the boiler is, it means how much power it has.

The amount of hot water you get from showers, bathrooms, and sinks and heat from your radiators depends on your boiler's output (measured in kilowatts). The higher the level of output, the better your home will be heated and you can be more certain that the water from your taps will be as hot as you want.

However, you must be careful. You might not get the hot water you want if your boiler output is too low. If it's too high, you'll be paying more than you need to for gas.

With the Viessmann Vitodens 050-W 29kW combi's output at 29 kW, which types of property would this Viessmann Vitodens 050-W 29kW Combi boiler be most appropriate for?

An experienced PlumbProud heating engineer would recommend that the most suitable type of property for a Viessmann Vitodens 050-W 29kW combi would be medium-sized homes and larger apartments containing 10-15 radiators and providing hot water for two bathrooms.

Please remember too that all combi boilers draw water from the mains - they have no storage tanks. Combis heat the water from the mains on demand and then send it to wherever it's needed in the house, like a radiator, a bathroom or a kitchen.

The speed at which it can do this is called the "flow rate", which is measured in litres per minute. If you have a lot of radiators and bathrooms in your home and multiple people are regularly trying to use the hot water at one time, such as in the morning or evening, you'll need a combi with a high flow rate. This Viessmann Vitodens 050-W 29kW Combi boiler's flow rate is 12 L/m.

However, it's not that simple. Combis can only draw water from the mains at the speed it's delivered. If the flow rate of the local water supply is 11l/m, you shouldn't purchase a boiler with a flow rate of 17l/m because it will never be able to use that extra capacity.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


How big is the Viessmann Vitodens 050-W 29kW?

The Viessmann Vitodens 050-W 29kW boiler measures 707 mm [H] x 400 mm [W] x 350 mm [D] in size.

Is the Viessmann Vitodens 050-W 29kW a condensing or non-condensing boiler?

We recommend the Viessmann Vitodens 050-W 29kW as it is a modern condensing gas boiler from a trusted manufacturer with a reputation for supplying highly energy-efficient boilers.

Condensing boilers capture the heat still present in water vapour condensation and flue exhaust gases and recycle it back into the heating system. With this extra energy, your boiler can, among other tasks, reheat colder water coming back from your radiators without having to burn more gas.

Condensing boilers significantly reduce your quarterly gas costs and they're better for the environment.

Is the Viessmann Vitodens 050-W 29kW combi a good choice for the environment?

How we heat our homes has become a pressing issue of concern for many homeowners worried about climate change and the environmental impact of their personal choices.

Central heating systems are responsible for 14% of greenhouse gas emissions in the UK. You may also be aware that the gas boilers we use emit dangerous nitrogen dioxide in large volumes in the bigger British cities.

Would installing a Viessmann Vitodens 050-W 29kW combi boiler in your home be a green choice? Let's look at the numbers.

All boilers manufactured and installed in the UK are required by law to have an energy efficiency rating of at least 92%, equivalent to a good “A” rating on the SEDBUK scale. Before this, the minimum was 88% (ratings of 88% and 89% are equivalent to a high “B” SEDBUK rating and anything 90% or higher is an "A" rating).

A boiler's energy efficiency rating is designed to let you know how much energy is used and wasted during normal functioning.

The Viessmann Vitodens 050-W 29kW was given an efficiency rating of 93% and a band rating of "A".

In 2015, the Energy Related Products Directive (ERP) came into force. The legislation applies to all products that consume energy in production, during their active life, and at the point of final disposal.

The ERP was introduced to incentivise manufacturers to create products that emitted fewer harmful gases with the larger aim of protecting the wider environment.

The Viessmann Vitodens 050-W 29kW has been awarded an ERP rating of "A" for heat and "A" for water.

How many years does the warranty period cover on a Viessmann Vitodens 050-W 29kW boiler?

A parts and labour warranty of 3 years is included when you purchase the Viessmann Vitodens 050-W 29kW boiler through PlumbProud.
