Viessmann Vitodens 222-F 25/30kW Combi Gas boiler frequently asked questions

Is the Viessmann Vitodens 222-F 25/30kW a combi, system or regular boiler?

If you’re looking for a combi boiler for your house or flat, you may wish to the consider the Viessmann Vitodens 222-F 25/30kW.

Combi boilers provide hot water or heating for your home on demand. You just need to turn the tap to get hot water or switch on the radiator and you’ll feel your home warm up within minutes.

In contrast, traditional boilers required either one or two large storage tanks to work - one to heat and keep water warm and the other to hold cold water for later heating. If the immersion tank was empty, it wasn’t uncommon to wait up to an hour for enough hot water to fill a bath, for example.

Combi boilers draw cold water from the mains and then heat it instantly whenever it's needed, all from one small unit.

The one disadvantage to combi boilers is that, if more than one point is in use at any one time (for example, if someone is taking a shower and another person turns on a hot water tap elsewhere in the property), water pressure, temperature and volume drop to both points.

Is a Viessmann Vitodens 222-F 25/30kW combi boiler appropriate for my house or apartment?

Selecting the right boiler for your home means choosing 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".

Your boiler’s output is a measurement of the power it has available to it to heat the water you need for your radiators or for when you turn on a tap, bath or shower. A higher output rate means it has more power and can heat more water.

It's important to choose an output that matches the demand for water in your home because if your boiler has too low an output, you'll often find only lukewarm water comes out of your taps or heats your radiators. If it’s too high, you’ll be paying more for your gas than you need to.

The Viessmann Vitodens 222-F 25/30kW combi has an output of 25 kW, so which types of property would this Viessmann Vitodens 222-F 25/30kW Combi boiler be appropriate for?

Most Gas Safe engineers would suggest that the most suitable type of property for installing a Viessmann Vitodens 222-F 25/30kW combi boiler would be smaller homes and apartments with up to 10 radiators and one bathroom.

With all combi boilers, you need to consider the "flow rate" as well as the output rate when making your decision.

Like all combi boilers, the Viessmann Vitodens 222-F 25/30kW draws water from the mains. It instantly heats that water and then distributes it to the parts of your home which need it - taps, radiators, bathrooms, and so on. This Viessmann Vitodens 222-F 25/30kW Combi boiler's flow rate is TBCl/m.

There is no benefit to purchasing a boiler with a high flow rate if the local water pressure is not that good - a high flow rate doesn't mean that your combi can draw more water from the mains.

In addition, if you live in a home with a large number of radiators and more than one bathroom and if more than one person regularly wants to use hot water at a time, a combi boiler may struggle to provide enough water at a hot enough temperature.

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.


Viessmann Vitodens 222-F 25/30kW dimensions

The Viessmann Vitodens 222-F 25/30kW measures 1,400 mm in height by 600 mm in width by TBC mm in depth.

Many homeowners still have floor-standing boilers like the Viessmann Vitodens 222-F 25/30kW even though wall-mounted boilers have been the preferred choice because of their compact size. If you want to replace your existing boiler with a compact wall-hung one to free up extra living space for you and your family, we can do this for you but please be aware that we may need to replace much of your existing pipework, which will incur an additional charge.

However, given the efficiency of modern wall-mounted gas boilers, the savings you make on your energy bills over the coming years should more than repay the cost of your investment.

If you are considering replacing your current heat only or system boiler with the Viessmann Vitodens 222-F 25/30kW, please be aware that this will involve removing your hot water cylinder and/or expansion tank.

For guidance and further information, please contact the team at PlumbProud who will be happy to help you make the right choice.

Is the Viessmann Vitodens 222-F 25/30kW condensing or non-condensing?

The Viessmann Vitodens 222-F 25/30kW is a condensing gas boiler - we strongly suggest that you choose either this model or a recently released model if at all possible.

A condensing boiler captures and recycles the warmth present in flue exhaust gases and water vapour condensation created by the burning of gas to warm up the water coming back into your boiler - for example, from your radiators.

Condensing boilers cost less to run (lower gas bills) and are better for the environment.

Does the Viessmann Vitodens 222-F 25/30kW combi protect the environment?

With more and more people concerned about climate change, how we heat our homes and the damage it does to the environment is increasingly being questioned by British homeowners.

In the UK, central heating is responsible for 14% of greenhouse gas production. Domestic gas boilers emit large quantities of nitrogen dioxide in British cities.

Would installing a Viessmann Vitodens 222-F 25/30kW combi boiler in your home help combat climate change? What do the figures suggest?

The Viessmann Vitodens 222-F 25/30kW has been awarded an efficiency rating of 92% and a SEDBUK band rating of "A".

In the UK, all boilers manufactured and supplied must have an energy efficiency rating of at least 92% or a SEDBUK "A" grade. Until April 2018, the minimum rating was 88% (88% and 89% are equivalent to a SEDBUK "B" rating and anything higher is rated "A").

A boiler's energy efficiency rating describes the amount of energy it uses and wastes when in normal operation.

The Energy Related Products Directive intends to encourage all manufacturers to reduce the harmful gas emissions associated with the products they make, from the manufacturing stage to final disposal, including when they are in active use.

The Viessmann Vitodens 222-F 25/30kW has an ERP rating of "A" for heat and "A" for hot water.

How long is the warranty period on a Viessmann Vitodens 222-F 25/30kW combi boiler?

The Viessmann Vitodens 222-F 25/30kW boiler is covered by a parts and labour warranty of 3 years.

Viessmann Vitodens 222-F 25/30kW Combi Gas boiler frequently asked questions

Is the Viessmann Vitodens 222-F 25/30kW boiler a combi, regular or a system boiler?

If you’re looking for a combi boiler for your house or flat, then the Viessmann Vitodens 222-F 25/30kW is one you may wish to consider.

Traditionally, most boilers required you to find space in your property for one or more large storage tanks. These tanks would either keep water warm or hold it in reserve for later heating. Manufacturers originally introduced combi boilers to offer homeowners the same level of warmth and hot water without taking up as much space – remember that the UK has some of the smallest homes in the Western world.

With a combi boiler, the hot water needed for your radiators and taps is provided on demand. Water from the mains passes through your combi boiler and the technology within it instantly heats the cold water. It then distributes that hot water around your home.

The biggest drawback for combi boilers is that they have a maximum capacity in volume for heating water. This means that if someone wants to use the shower while another person wants to use a hot water tap, the amount of water reaching each point falls, resulting in a drop in water pressure.

Is a Viessmann Vitodens 222-F 25/30kW combi boiler suitable for my house or apartment?

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

Your boiler’s output is a measurement of the power it has available to heat the volume of water required for your taps and radiators. The higher the output rate, the more water it can heat.

You need to be careful to select a boiler with the optimal level of output for your property though. That's because, if your boiler output is too low, your water and radiators will often not be as hot as you want them to be. If the output is too high, you’ll be paying more for gas than you need to.

The output of the Viessmann Vitodens 222-F 25/30kW combi is 25 kW, so which types of property would this Viessmann Vitodens 222-F 25/30kW Combi boiler be appropriate for?

A boiler engineer would recommend that, at this level of output, the most suitable type of property for this Viessmann Vitodens 222-F 25/30kW Combi boiler would be smaller homes and apartments with up to 10 radiators and one bathroom.

If you are thinking about installing a combi boiler like the Viessmann Vitodens 222-F 25/30kW in your home, you should consider flow rates as well as output rates. This Viessmann Vitodens 222-F 25/30kW Combi boiler's flow rate is TBCl/m.

The flow rate indicates the maximum volume of water (measured in litres per minute) that your boiler can heat up and send to your radiators, taps and showers at any one time. The more taps and showers that could be in use simultaneously or the greater the number of radiators you have, the higher the flow rate you need.

However, you should establish what the mains pressure is at your property as a combi boiler can only heat the water that comes into your home.

For example, if your mains pressure is 12 litres per minute, your boiler can only heat and distribute hot water at a rate of 12 litres per minute even if it has a higher flow rate capacity. Typically, a power shower will require 10 litres of water per minute.

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.


Viessmann Vitodens 222-F 25/30kW - size in millimetres

The Viessmann Vitodens 222-F 25/30kW measures 1,400 mm in height by 600 mm in width by TBC mm in depth.

Hundreds of thousands of properties still have floor-standing boilers like the Viessmann Vitodens 222-F 25/30kW in the UK, although wall-hung boilers are now the obvious choice for most homeowners wanting more living space. It is possible to replace your existing floor-standing boiler with one that is compact if you'd like to but you should consider that much of the pipework will need to be replaced in addition to the cost of the boiler and its installation.

Eventually, your savings on gas bills will pay for the one-time investment but it will take a few years.

If you are going to replace your current heat only or system boiler with the Viessmann Vitodens 222-F 25/30kW, you'll also need to budget for the removal of your hot water cylinder and/or expansion tank.

Please get in touch with PlumbProud if you would like information and guidance on the best course of action and we will share our advice with you.

Viessmann Vitodens 222-F 25/30kW – non-condensing or condensing?

Condensing gas boilers like the Viessmann Vitodens 222-F 25/30kW 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.

How environmentally friendly is the Viessmann Vitodens 222-F 25/30kW combi?

With so many of us worried about the environmental impact of our personal choices, the relationship between how we heat our homes and climate change has become an important issue for many homeowners.

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.

If you would like your next boiler to help in the fight against climate change, would the Viessmann Vitodens 222-F 25/30kW combi be a suitable choice?

In the UK, by law, all boilers manufactured since April 2018 must have a SEDBUK “A” rating and operate to a minimum level of 92% energy efficiency. Prior to this, the minimum was 88% – 88/89% would score a "B" and 90% or more an "A" on the SEDBUK scale.

The energy efficiency rating measures the amount of energy a boiler consumes when it's in use and how much it loses on non-core operations.

Following testing, the Viessmann Vitodens 222-F 25/30kW was given an efficiency rating of 92% and a SEDBUK grading 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 222-F 25/30kW, the ERP Heat rating is "A" and the ERP Water rating is "A".

What is the length of the warranty on the Viessmann Vitodens 222-F 25/30kW?

A parts and labour warranty of 3 years is included with the Viessmann Viessmann Vitodens 222-F 25/30kW boiler.
