Viessmann Vitodens 100-W 19kW heat only Gas boiler frequently asked questions

Viessmann Vitodens 100-W 19kW - a combi boiler, system boiler or regular boiler?

The Viessmann Vitodens 100-W 19kW is a heat only boiler you may wish to consider if you want this particular type of boiler for your house or flat.

Heat only boilers (often referred to as standard boilers, regular boilers or conventional boilers) need both a hot water cylinder and a cold water tank to work. The hot water cylinder heats and keeps warm the water you need and is normally installed in either a utility room or attic. The cold water tank holds water which it passes to the hot water cylinder depending on how you've programmed your boiler.

When you program a heat only boiler, you set the times and days when you want central heating and hot water to be available. However, if you don't remember to program your boiler and there's no water left in the hot water cylinder, you may have to wait up to an hour for hot water to come out of your taps.

Heat only boilers can cope with the demand for hot water from multiple taps and sources around your home simultaneously. That's why they're better for larger homes than combi boilers - combi boilers struggle when more than one hot tap is turned on. This is because they have a maximum capacity of water they can heat and distribute at any one time, meaning water pressure, temperature and volume to each tap drops.

Is the Viessmann Vitodens 100-W 19kW heat only boiler a suitable option for my house or flat?

Selecting the right boiler for your property means selecting a boiler that is the right size. And, by size, we don't mean how big it is, we mean how powerful it is - the "output".

The output of a boiler is measured in kilowatts. The output level determines the maximum power a boiler can use in heating the water needed for the baths, showers, taps and radiators in your home.

It's important to choose a boiler with an appropriate level of output for your property. Your boiler should be able to cope with periods of peak demand in your property and not just your average usage.

An output rate that is too low will result in an inadequate supply of hot water, while an output that is too high will mean the boiler will cost more to run than is necessary.

The output of the Viessmann Vitodens 100-W 19kW heat only is 19 kW kilowatts, so which types of property would this be appropriate for?

An experienced PlumbProud Gas Safe boiler installer would recommend that this Viessmann Vitodens 100-W 19kW heat only boiler is appropriate for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


The size of the Viessmann Vitodens 100-W 19kW in millimetres

The Viessmann Vitodens 100-W 19kW is 600 mm high by 375 mm wide by 285 mm deep.

Vitodens 100-W 19kW – non-condensing or condensing?

We strongly recommend that you choose a condensing boiler like the Viessmann Vitodens 100-W 19kW - the technology is improving every year so the newer the boiler, the better.

A condensing boiler captures and recycles the warmth still present in flue exhaust gases and water vapour condensation into heat, allowing it to perform more efficiently on tasks like heating the colder water returning from your radiators.

They also offer significant annual savings on household gas bills as well as being more environmentally friendly.

Is the Viessmann Vitodens 100-W 19kW heat only boiler rated as environmentally friendly?

As more of us become concerned by the effects of climate change, the damage we do to the environment by heating our homes has emerged as an important issue for many homeowners.

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.

Will installing a Viessmann Vitodens 100-W 19kW heat only be a positive contribution to the environment? Let's see what the experts say.

Under current UK law, all boilers must achieve a minimum energy efficiency level of 92% (a low to good SEDBUK "A" rating). The minimum level was raised from its previous 88% in April 2018.

Energy efficiency scores are intended to inform consumers of the amount of energy used and wasted when a boiler is in normal operation.

The Viessmann Vitodens 100-W 19kW was awarded an efficiency rating of 94% with a SEDBUK band rating of "A".

The Energy Related Products (ERP) Directive is important European legislation that aims to limit energy use and harmful gas emissions during the manufacturing process, when the product is in use, and after it is disposed of.

For the Viessmann Vitodens 100-W 19kW, the ERP Heat rating is "A".

What warranty does the Viessmann Vitodens 100-W 19kW heat only boiler come with?

On the Viessmann Vitodens 100-W 19kW, the manufacturer offers a parts and labour warranty of 5 years.

Viessmann Vitodens 100-W 19kW heat only Gas boiler frequently asked questions

Is the Viessmann Vitodens 100-W 19kW a combi, system or regular boiler?

The Viessmann Vitodens 100-W 19kW is a heat only boiler you may wish to consider if you want this particular type of boiler for your house or flat.

Sometimes called regular boilers, conventional boilers or standard boilers, heat only boilers require a cold water tank (often kept in the loft) and a hot water cylinder and an immersion heater (often kept in a landing or airing cupboard) to work. The immersion heater heats the water and keeps it warm.

With a heat only boiler, you pre-set a timer to tell the system when you want it to provide you with hot water and central heating. Remember though, if you don't program it and there's no water left in the hot water cylinder, you'll have to wait up to an hour before running a bath or shower.

Heat only boilers are better for larger homes or homes with more than one bathroom where there is a high demand for hot water at certain times of the day. Unlike with combi boilers where water pressure, volume and temperature drops if, for example, more than one person is using a hot tap, regular boilers can cope with multiple members of your household wanting hot water at the same time.

Should I install a Viessmann Vitodens 100-W 19kW heat only boiler in my house or apartment?

Whether this Viessmann Vitodens 100-W 19kW heat only boiler is right for your property depends on its size or what its "output" level is. Size does not mean its physical dimensions, however - it means how powerful it is.

The output rating indicates how much energy a boiler can use in providing you with hot water and heat when you need it from your radiators and taps. The greater the output, the more water it can heat.

It's better to take advice on this from a registered installer because, if your boiler output is too low, your water and radiators might not get as hot as you would like them to be. However, if the output level is too high, you'll end up paying more on your gas bills than you need to.

Which types of property would this Viessmann Vitodens 100-W 19kW heat only boiler be appropriate for given its output of 19 kW?

A PlumbProud boiler engineer would almost certainly recommend that this Viessmann Vitodens 100-W 19kW heat only boiler is most suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


Viessmann Vitodens 100-W 19kW dimensions

The Viessmann Vitodens 100-W 19kW boiler is 600 mm high, 375 mm wide, and 285 mm deep.

Is this Viessmann boiler condensing or non-condensing?

Condensing gas boilers like the Viessmann Vitodens 100-W 19kW are environmentally friendlier and cheaper to run so, if possible, we strongly recommend that you choose this or one of the very latest models.

Condensing boilers are much more efficient and economical to run because they contain a secondary heat exchanger that captures and recycles the warmth still present in the flue exhaust gases and the water vapour condensation for re-use, meaning that they use less gas to run.

Does the Viessmann Vitodens 100-W 19kW heat only protect the environment?

More and more homeowners are aware of the importance of how we heat our homes and its impact on climate change and other environmental issues.

In Britain's bigger cities, gas boilers, in particular, are responsible for dangerous levels of nitrogen dioxide emissions. Overall, 14% of all of the UK’s greenhouse gas production comes from heating our homes.

Would the environmental impact of installing a Viessmann Vitodens 100-W 19kW heat only in your home be positive? Let's look at the numbers.

All boilers manufactured after April 2018 in the UK must be rated as an “A” on the SEDBUK grading system, subject to a minimum energy efficiency rating of 92% or above. Before that, the minimum rate was 88% - boilers with an energy efficiency of 88% or 89% were given a “B” rating. Boilers scoring 90% or more were given an "A" rating.

The energy efficiency rating for a boiler describes the amount of energy it uses and how much goes to waste in operation.

The Viessmann Vitodens 100-W 19kW has an efficiency rating of 94% with a SEDBUK grade 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 100-W 19kW is "A".

What is the warranty period for the Viessmann Vitodens 100-W 19kW?

The Viessmann Vitodens 100-W 19kW boiler comes with a parts and labour warranty lasting 5 years.
