Is the Viessmann Vitodens 222-F 19kW a combi, system or regular boiler?

Viessmann’s Vitodens 222-F 19kW is one you might consider if you’re looking for a combi 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.

Would the Viessmann Vitodens 222-F 19kW combi 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, by size, we don't mean how big it is, we mean how powerful it is - the "output".

Your boiler has to be powerful enough to heat all the hot water you need for your radiators and taps. Power is measured in kilowatts and the more kilowatts a boiler has available to it, the more water it can heat.

If the output (measured in kilowatts) is too high, you'll have all the power you need and more but your gas bills will be much higher. If it's too low, you'll often find that the water coming out of your taps and fed into your radiators is only lukewarm.

With the Viessmann Vitodens 222-F 19kW combi's output at 19 kW, which types of property would this Viessmann Vitodens 222-F 19kW Combi boiler be most appropriate for?

A Gas Safe boiler installer would recommend that this Viessmann Vitodens 222-F 19kW Combi boiler would provide adequate heating and hot water for smaller homes and apartments with up to up to 10 radiators and one bathroom.

You also need to choose a combi boiler with the right flow rate for where you live.

A combi boiler's flow rate is the maximum volume of water (measured in litres per minute) that it can heat and distribute to your radiators, taps and showers at the same time. This Viessmann Vitodens 222-F 19kW Combi boiler's flow rate is TBCl/m.

However, combi boilers like the Viessmann Vitodens 222-F 19kW draw water directly from the mains and heat it instantly.

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.

Combi boilers also struggle when multiple people in your home want to use hot water at the same time - for example, someone running the hot water tap in the kitchen and two people wanting to shower in separate bathrooms.

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.

Where will the Viessmann Vitodens 222-F 19kW fit in my house?

The Viessmann Vitodens 222-F 19kW is 1,400 mm tall, 600 mm wide, and TBC mm deep in size.

While, in the last 20 years, wall-hung boilers have become the product of choice for most homeowners in the UK, there are still hundreds of thousands of floor-standing boilers like the Viessmann Vitodens 222-F 19kW in use across the country. You can replace your existing floor-standing boiler with a compact wall-mounted unit if you want to free up space and but you'll likely have to pay for new piping and pipework.

The savings on your gas bills will save you more than you pay for your new smaller boiler but this will take a few years.

If you're considering replacing your current heat only or system boiler with the Viessmann Vitodens 222-F 19kW, please note that you'll need to budget for the removal of your hot water cylinder and expansion tank.

Is the Viessmann Vitodens 222-F 19kW condensing or non-condensing?

We strongly recommend that you choose a condensing boiler like the Viessmann Vitodens 222-F 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 combi Viessmann Vitodens 222-F 19kW boiler energy efficient?

Many homeowners are now worried about climate change and the damage they do to the environment from heating their homes has become a subject of increasing concern.

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.

Will you be helping the environment if you decide to install a Viessmann Vitodens 222-F 19kW combi in your home? Let’s look at the figures.

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 222-F 19kW was awarded an efficiency rating of 92% with a SEDBUK band rating of "A".

In 2015, new legislation was introduced by the EU to encourage manufacturers to develop more energy-efficient products that emit fewer harmful gases throughout their lifetime.

The Energy Related Products Directive (ERP) applies to all products that consume energy, including during the manufacturing process, at the point of final disposal, and all points in between.

The ERP rating of the Viessmann Vitodens 222-F 19kW is "A" for heat and "A" for hot water.

How long am I covered by the warranty for if the Viessmann Vitodens 222-F 19kW breaks down?

The Viessmann Vitodens 222-F 19kW boiler has a warranty covering parts and labour costs for up to 3 years after installation.
