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

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

The Viessmann Vitodens 100-W 19kW boiler is an option you may wish to consider if you're looking for a heat only boiler for your house or flat.

If your home has more than one bathroom or you have a large family which uses a lot of hot water, a heat only boiler (sometimes called a regular boiler, a conventional boiler or a standard boiler) is likely to be the best option for you. Heat only boilers require both a hot water or immersion cylinder and a cold water tank. Once the water in the cylinder is heated, you can use this hot water throughout the day and it can feed multiple taps and showers at the same time.

This is in contrast to a combi boiler which can only heat a limited amount of water at any one time. This can cause a problem if two or more taps and showers are being used simultaneously as the temperature, pressure and volume to all points will drop.

Heat only boilers allow you to program the times that you wish heat and hot water to be available. However, if you forget to do this and the immersion cylinder is empty, you may have to wait up to an hour before hot water becomes available again.

If your property already has a water tank and cylinder, it will nearly always be cheaper to replace like for like and not choose a different type of boiler. In addition to new pipework, you may need to replace older radiators that may be unable to cope with the higher water pressure delivered by other types of boiler.

Is the Viessmann Vitodens 100-W 19kW heat only boiler the right choice for my house or apartment?

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

Measured in kilowatts, a boiler's output level is an indication of the amount of power it has available to it to heat the water coming from your taps and for warming your radiators. The greater the output level, the more water it can heat.

If you choose a boiler whose output level is too low, you'll often find that the water is not as hot as you want it to be. If you choose a boiler whose level is too high, you'll be paying higher gas bills than you need to for years to come.

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

Most experienced boiler engineers would recommend that this Viessmann Vitodens 100-W 19kW heat only boiler would be suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


Viessmann Vitodens 100-W 19kW - size in millimetres

The Viessmann Vitodens 100-W 19kW is 600 mm in height, 375 mm in width and 285 mm in depth.

Is the Viessmann Vitodens 100-W 19kW non-condensing or condensing?

This Viessmann Vitodens 100-W 19kW is a condensing gas boiler - we always recommend that clients choose the latest condensing models to benefit from the technology, which continues to improve year after year.

Condensing boilers capture the heat still present in flue exhaust gases and water vapour condensation, processing them through a secondary heat exchanger to, among other tasks, heat colder water returning from your radiators.

By selecting a modern condensing boiler, you'll save money on your gas bills as well as benefitting the wider environment.

Is the Viessmann Vitodens 100-W 19kW heat only considered environmentally friendly?

Many homeowners are becoming increasingly concerned about how they heat their homes and the impact it has on climate change and other important environmental issues.

The power we need for our central heating systems accounts for around 14% of the UK’s greenhouse gas production. There are often dangerous levels of ambient nitrogen dioxide gases in the atmospheres of British cities because of our use of gas boilers.

Will you be helping the environment if you decide to install a Viessmann Vitodens 100-W 19kW heat only in your home? Let’s look at the figures.

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 100-W 19kW was given an efficiency rating of 94% and a band rating of "A".

The ERP, short for the Energy Related Products Directive, is a European directive aimed at encouraging manufacturers to create products that are environmentally friendlier at all stages, including during manufacturing, when the product is in active use, and right through to the point of final disposal.

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

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

The Viessmann Vitodens 100-W 19kW boiler is a heat only boiler you may wish to consider when looking for a new 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.

Would the Viessmann Vitodens 100-W 19kW heat only be a suitable choice of boiler for my house or flat?

You should make sure that the boiler you install in your property is the right "size". And size doesn't mean its physical dimensions, size means how much power it has - the "output".

Your boiler should be able to cope with peak hot water demand in your property and not just your average hot water usage. The output rate of a boiler is measured in kilowatts and tells you how much power a boiler can use to provide hot water to your taps, showers and radiators.

If the output of your boiler is too low, there will often be times when your water isn't as hot as you want. But if your boiler output is too high, it will be more costly to run (often unnecessarily).

The output of the Viessmann Vitodens 100-W 19kW heat only boiler is 19 kW kilowatts. Which types of property would this be appropriate for?

Most experienced heating engineers would suggest that the most suitable type of property for installing a Viessmann Vitodens 100-W 19kW heat only boiler in would be medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


Making space for the Viessmann Vitodens 100-W 19kW

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

Is the Viessmann Vitodens 100-W 19kW non-condensing or condensing?

The Viessmann Vitodens 100-W 19kW is a condensing gas boiler - we’d strongly recommend that you choose the very latest condensing model for your home.

Condensing boilers run on either gas or oil and are manufactured specifically to improve energy efficiency. They do this by capturing and recycling the warmth present in flue exhaust gases and water vapour condensation into more usable heat the system can use, meaning they're far more efficient and cost less to run.

How does the Viessmann Vitodens 100-W 19kW heat only boiler rate environmentally?

Environmentally-friendly heating has become an important issue for homeowners concerned about the accelerating pace of climate change.

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.

Do the figures suggest that installing the Viessmann Vitodens 100-W 19kW heat only at your property would help in the fight against climate change?

An energy efficiency rating of 92% or above is a legal requirement for all boilers manufactured and installed in the UK today. 92% is equivalent to a low-to-middle "A" grade on the "Seasonal Efficiency of Domestic Boilers" (SEDBUK) scale.

Energy efficiency measures how much energy a boiler uses and wastes in the course of its normal operation. The lower the waste, the lower your gas bills.

The Viessmann Vitodens 100-W 19kW was awarded an efficiency rating of "94%", equivalent to a "A" rating on the SEDBUK system.

The ERP, short for the Energy Related Products Directive, is a European directive aimed at encouraging manufacturers to create products that are environmentally friendlier at all stages, including during manufacturing, when the product is in active use, and right through to the point of final disposal.

The Viessmann Vitodens 100-W 19kW has a rating of "A" .

How many years' warranty does the Viessmann Vitodens 100-W 19kW heat only come with?

The Viessmann Vitodens 100-W 19kW boiler offers a parts and labour warranty of 5 years.
