Viessmann Vitodens 200-W 25/30kW Combi Gas boiler frequently asked questions

What type of boiler is the Viessmann Vitodens 200-W 25/30kW?

The Viessmann Vitodens 200-W 25/30kW boiler is a combi boiler you may wish to consider when looking for a new boiler for your house or flat.

Traditional boilers would require you to install one or more storage tanks in your property. These tanks either kept the water warm or stored it for later heating. Manufacturers initially designed and introduced combi boilers to the market to offer homeowners the highest levels of warmth and unlimited hot water without taking up as much space.

Combi boilers provide hot water on demand for your radiators and taps. They take water directly from the mains, heat it immediately as it's needed, and then distribute the hot water around your home.

Combi boilers, however, are limited in terms of how much water they can heat at any given time. For example, if one person wishes to take a shower while another wants to turn on a hot water tap, the amount of water reaching each point drops. This results in a drop in the water pressure as well as the temperature.

Is the Viessmann Vitodens 200-W 25/30kW combi boiler suitable for my house or apartment?

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 - its "output".

The output rate tells you how much energy your boiler has to use to provide you and your family with hot water and central heating. A higher output rate means that it can heat greater volumes of water.

Please be aware, though - if you choose a boiler whose output is too low, the water in your radiators and coming from your taps may not be warm enough. Conversely, if you choose a boiler with too high an output, you'll pay more for gas than is necessary.

The Viessmann Vitodens 200-W 25/30kW combi boiler has an output level of 25 kW, so which types of property would it be appropriate for?

Most boiler engineers would recommend that a boiler with this output level would be most suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

You need to consider the flow rate as well as the output rate when choosing a combi boiler.

Flow rates, measured in litres per minute, indicate how much water your boiler can heat and distribute around your home at any given time. If your family regularly use hot water around the house at the same time and you have a lot of radiators, you should choose a boiler with a high flow rate. This Viessmann Vitodens 200-W 25/30kW Combi boiler's flow rate is 16 L/m.

However, you also need to consider the flow rate of your local mains water supply. Combis can only draw water from the mains as fast as the pipes can deliver it. If you choose a boiler with a 14l/m flow rate and the mains pipes into your home have a flow rate of 12l/m, your boiler won't be able to operate at full capacity. In other words, try to make sure the local water pressure and your boiler flow rates are as close as possible.

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.


The size of the Viessmann Vitodens 200-W 25/30kW in millimetres

The Viessmann Vitodens 200-W 25/30kW is 700 mm tall, 450 mm wide, and TBC mm deep in size.

Is the Viessmann Vitodens 200-W 25/30kW non-condensing or condensing?

How does the Viessmann Vitodens 200-W 25/30kW combi boiler rate environmentally?

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.

Central heating produces 14% of all greenhouse gas emissions in the UK. Gas boilers in the larger cities emit dangerous levels of nitrogen dioxide.

Would choosing the Viessmann Vitodens 200-W 25/30kW combi be an environmentally-friendly choice? If so, let's look at its performance figures.

Boilers manufactured in the UK must be tested and, by law, achieve an energy efficiency rating of 92% or above, equivalent to a SEDBUK "A" grade. Most boilers achieve an "A" rating meaning they are at least 88% efficient.

The energy efficiency of a boiler indicates the amount of energy it uses (and wastes) during operation.

The Viessmann Vitodens 200-W 25/30kW has been assigned an efficiency rating of 94% with a SEDBUK rating of "A".

What length of warranty does the Viessmann Vitodens 200-W 25/30kW come with?

The Viessmann Vitodens 200-W 25/30kW boiler offers a parts and labour warranty of 3 years.

Viessmann Vitodens 200-W 25/30kW Combi Gas boiler frequently asked questions

Is this Viessmann Vitodens 200-W 25/30kW boiler a combi, system or regular boiler?

You may wish to consider installing the Viessmann Vitodens 200-W 25/30kW if you are looking for a combi boiler for your house or flat.

Traditional boilers have one or more large tanks in which they store either heated water or water to be heated later. Manufacturers originally introduced combi boilers to the market in the 1970s to enable homeowners to save space - UK residential properties are among the smallest in the Western world.

Combi boilers don't need these tanks because they draw water directly from the mains and instantly heat it on demand thanks to the technology inside the boiler. Combi boilers then distribute this hot water to your home’s taps and radiators when needed.

The most significant disadvantage of combi boilers is that they are not ideal in larger homes where multiple people might want hot water at the same time – for example, if someone is having a shower while another wants to wash dishes in the kitchen. This is because combi boilers have a maximum volume of water that they can heat. When two people want hot water at the same time, the water temperature, pressure and volume delivered to both points drop.

Is a Viessmann Vitodens 200-W 25/30kW combi boiler suitable for my house or apartment?

To determine that, we need to consider the size of the boiler. Size doesn't mean how big it is - it means how big its "output" is.

The output rate of a boiler tells you how much power it has available to it for heating the water that comes out of your taps and warms your radiators. A higher output rate means that your boiler has more power at its disposal.

You need to make sure you select a boiler with the right output rate. That's because, if your output rate is too high, then your boiler will have more power than it needs but it will cost too much to run. If the output rate is too low, your water may often not be hot enough.

The Viessmann Vitodens 200-W 25/30kW combi's output is 25 kW, so which types of property would this Viessmann Vitodens 200-W 25/30kW Combi boiler be appropriate for?

Most experienced heating engineers would likely recommend that, at this level of output, this Viessmann Vitodens 200-W 25/30kW Combi boiler would be a suitable choice for smaller homes and apartments with up to 10 radiators and one bathroom.

You need to consider the flow rate as well as the output rate when choosing a combi boiler.

Flow rates, measured in litres per minute, indicate how much water your boiler can heat and distribute around your home at any given time. If your family regularly use hot water around the house at the same time and you have a lot of radiators, you should choose a boiler with a high flow rate. This Viessmann Vitodens 200-W 25/30kW Combi boiler's flow rate is 16 L/m.

However, you also need to consider the flow rate of your local mains water supply. Combis can only draw water from the mains as fast as the pipes can deliver it. If you choose a boiler with a 14l/m flow rate and the mains pipes into your home have a flow rate of 12l/m, your boiler won't be able to operate at full capacity. In other words, try to make sure the local water pressure and your boiler flow rates are as close as possible.

Is the Viessmann Vitodens 200-W 25/30kW condensing or non-condensing?

Is the Viessmann Vitodens 200-W 25/30kW combi good for the environment?

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

Central heating produces 14% of all greenhouse gas emissions in the UK. Gas boilers in the larger cities emit dangerous levels of nitrogen dioxide.

Would installing a Viessmann Vitodens 200-W 25/30kW combi boiler in your home help combat climate change? What do the figures suggest?

Boilers manufactured in the UK must be tested and, by law, achieve an energy efficiency rating of 92% or above, equivalent to a SEDBUK "A" grade. Most boilers achieve an "A" rating meaning they are at least 88% efficient.
