What type of boiler is the Viessmann Vitodens 222-F 19kW - regular, system or combi?

Suitable for a house or a flat, the Viessmann Vitodens 222-F 19kW combi boiler is worth considering if you want a combi boiler.

In older British homes, traditional boilers required you to find room for one or more storage tanks. One tank would keep hot water warm and the other stored cold water for later heating. Manufacturers introduced combi boilers to the UK in the 1970s so that homeowners could get the warmth and hot water they needed without having to sacrifice too much valuable space – remember that residential property in this country is among the smallest in the Western world.

Combi boilers deliver hot water to your radiators and taps using water they draw directly from the mains supply. As mains water travels through a combi boiler, the technology within it heats the cold water instantly and on demand. The hot water is then distributed throughout your house.

Combi boilers have one drawback, however: they can only heat a certain amount of water within a given time. For example, if someone uses the shower and another person uses the hot water tap at the same time, water pressure drops because water reaches each point differently.

Is the Viessmann Vitodens 222-F 19kW combi boiler a suitable choice for my property?

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 222-F 19kW combi boiler is 19 kW kilowatts. Which types of property would this 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.

Flow rates are important when choosing a combi boiler as well as output rates.

A combi boiler's flow rate (measured in litres per minute) describes how much water it can instantly heat then distribute to the taps and radiators in your home - you will need to factor this into your decision on a new combi boiler. This Viessmann Vitodens 222-F 19kW Combi boiler's flow rate is TBCl/m.

If you have a lot of radiators and bathrooms in your home and there's lots of demand within your household for hot water at the same time (like morning or evening showers and baths), you'll need a boiler with a high flow rate.

However, it's not quite that simple. If your local mains water pressure is low, you're not going to gain any benefit from choosing a combi boiler with a high flow rate because that higher flow rate doesn't mean it can draw more water from the mains pipes.
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.

Dimensions of the Viessmann Vitodens 222-F 19kW boiler

The size of the Viessmann Vitodens 222-F 19kW boiler is 1,400 mm high, 600 mm wide, and TBC mm deep.

If you want to replace your floor-standing boiler with a more compact, wall-mounted model, this will give you and your family more space. Hundreds of thousands of homes in the UK still use floor-standing boilers like the Viessmann Vitodens 222-F 19kW, but wall-mounted models have been the most popular choice for homeowners over the last two decades. We can replace your floor-mounted unit with a wall-mounted unit, but please be aware that the cost of installation will be higher if we need to replace your current piping.

However, you can recoup this investment in full over a few years with the savings you make on your gas bills.

Replacing an existing heat only or system boiler with the Viessmann Vitodens 222-F 19kW will also require our fitters to remove and dispose of your hot water cylinder/expansion tank.

Is this Viessmann boiler condensing or non-condensing?

We recommend that you select a condensing boiler like the Viessmann Vitodens 222-F gas Viessmann Vitodens 222-F 19kW for your home if possible because of the environmental benefits and the money you'll save on your gas bills.

Condensing boilers are much more energy-efficient than older, non-condensing models as they capture and recycle the heat still present in the water vapour condensation and flue exhaust gases that your boiler creates when burning gas for reuse.

Is the Viessmann Vitodens 222-F 19kW combi good for 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.

Dangerous levels of nitrogen dioxide emissions in larger UK cities are caused by gas boilers in domestic properties, and 14% of the UK’s greenhouse gas production is as a result of central heating.

Would choosing a Viessmann Vitodens 222-F 19kW combi help the environment? Let’s see what the performance figures suggest.

By law, the minimum level of energy efficiency for boilers manufactured in the UK is 92%, equivalent to a good SEDBUK “A” rating. Prior to April 2018, the minimum was 88% - boilers whose energy efficiency levels were 88% or 89% were given a "B" rating on the SEDBUK scale and those at 90% or higher were given an "A".

The energy efficiency rating awarded to each boiler indicates the amount of energy that is wasted when in operation.

Following testing, the Viessmann Vitodens 222-F 19kW was given a 92% energy efficiency rating and a SEDBUK grading of "A".

Energy-efficient boilers help the environment as they require less fuel and emit fewer harmful gases. In 2015, the EU introduced the Energy Related Products Directive (ERP), the aim of which was to ensure that all manufacturers, including boiler manufacturers, developed more efficient products and processes.

The legislation aims to conserve energy at all life cycle stages from initial production to actual use by the customer, through to the point of disposal.

The Viessmann Vitodens 222-F 19kW has been given an ERP rating of "A" for heat and "A" for 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 offers a parts and labour warranty of 3 years.
