Vokera Evolve C 18S System Gas boiler frequently asked questions

Which category of boiler does the Vokera Evolve C 18S fit into?

The Vokera Evolve C 18S is a gas system boiler.

System boilers need a hot water cylinder to work but, unlike heat only boilers, they don't require a cold water tank. This can be advantageous if you live in an apartment, lack attic space, or are planning a loft conversion.

System boilers allow you to set the times when you want hot water to be available. Heated water is stored in the cylinder and can be used throughout the day. With a system boiler, if you forget to set the timer, you will have to wait a while for hot water.

The constant supply of hot water from the cylinder ensures that you can have multiple taps and showers in use without a loss of pressure to each point (something combi boilers struggle with). This makes a system boiler suitable for large families and homes with more than one bathroom.

Is the Vokera Evolve C 18S system boiler suitable for my house or apartment?

It's best to choose a boiler whose size or "output" is right for your home.

The more hot water and heat you want, the higher the output level of your boiler should be. Output is measured in kilowatts and it describes the maximum level of power your boiler has to heat water.

If your output level is too low, your boiler will not have the power it needs to get your water as hot as you want it, particularly when there's a lot of demand for it. Choose a boiler whose output level is too high and you'll have all the hot water you need but will be paying too much for it through higher gas bills.

Which types of property would this Vokera Evolve C 18S System boiler be appropriate for given its output of 18 kW?

An experienced PlumbProud heating engineer would recommend that the level of output from this Vokera Evolve C 18S System boiler would make it a suitable installation option for smaller homes and apartments with up to 10 radiators and one bathroom.


What size is the Vokera Evolve C 18S boiler?

The Vokera Evolve C 18S is 955 mm tall, 489 mm wide, and 333 mm deep in size.

Is the Vokera Evolve C 18S condensing or non-condensing?

Condensing boilers convert the warmth present in flue exhaust gases and water vapour condensation into heat which they then recycle to increase the temperature of the colder water returning to your system.

We recommend that homeowners choose a condensing boiler like the Vokera Evolve C 18S for this reason - the more recent your model the better because the technology improves every year.

You'll benefit from lower quarterly gas bills and condensing boilers are also much more environmentally friendly.

Is the Vokera Evolve C 18S system environmentally friendly?

How we heat our homes and the effect that has on climate change has become important to many homeowners worried about the environment.

As much as 14% of the UK’s greenhouse gas production derives from our domestic central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in Britain's largest cities.

Will installing a Vokera Evolve C 18S system be a positive contribution to the environment? Let's see what the experts say.

Boilers manufactured or supplied to UK domestic properties must achieve a legal minimum energy efficiency rating of 92% (equivalent to a good "A" grade using the SEDBUK scale). Prior to this, the minimum was 88% (88% and 89% are a "B" SEDBUK grade and anything 90% or above is an "A" grade).

The energy efficiency rating of a boiler refers to the amount of energy it uses to perform its everyday functions as well as the amount of energy it wastes.

The Vokera Evolve C 18S has been given a rating of 94% for energy efficiency, equivalent to a SEDBUK "A" rating.

Will I be covered if the Vokera Evolve C 18S system breaks down?

You receive a parts and labour warranty of 10 years with the Vokera Evolve C 18S boiler.

Vokera Evolve C 18S System Gas boiler frequently asked questions

Which category of boiler does the Vokera Evolve C 18S fit into?

The Vokera Evolve C 18S boiler is an option you may wish to consider if you're looking for a system boiler for your house or flat.

System boilers are suitable for homes with a higher-than-average demand for central heating and water - for example, larger homes and larger families.

Tell the boiler when you want hot water using the control panel - it draws water from the mains, heats it and keeps it warm throughout the day in the hot water cylinder. As long as you remember to tell the boiler when you want hot water, you have a big enough cylinder, and there's not an unusually high demand for water on a particular day, you should have hot water whenever you need it.

System boilers do not require a cold water storage tank either, unlike heat only boilers, meaning they're cheaper, quicker and easier to install.

Is a Vokera Evolve C 18S system boiler suitable for my house or flat?

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 - the "output".

The output of a boiler is measured in kilowatts. The output level determines the maximum power a boiler can use in heating the water needed for the baths, showers, taps and radiators in your home.

It's important to choose a boiler with an appropriate level of output for your property. Your boiler should be able to cope with periods of peak demand in your property and not just your average usage.

An output rate that is too low will result in an inadequate supply of hot water, while an output that is too high will mean the boiler will cost more to run than is necessary.

The output of the Vokera Evolve C 18S system is 18 kW kilowatts, so which types of property would this be appropriate for?

A heating engineer would recommend that the Vokera Evolve C 18S system boiler would be a suitable installation option for smaller homes and apartments with up to 10 radiators and one bathroom.


What size is the Vokera Evolve C 18S boiler?

The measurements of the Vokera Evolve C 18S are 955 mm by 489 mm by 333 mm.

Is this Vokera boiler condensing or non-condensing?

The Vokera Evolve C 18S is a condensing gas boiler - this is the type of boiler we recommend to most clients because they're better for the environment and they will save money on annual fuel bills.

A condensing boiler captures and recycles the warmth still present in both the flue exhaust gases and water vapour condensation created when gas is burned to provide your boiler with power.

This means it needs less gas to operate and it uses this extra energy to perform a number of tasks, including heating the colder water that comes back to the boiler from the radiators in your home.

Is the Vokera Evolve C 18S system environmentally friendly?

As the British public has become more conscious of climate change, many homeowners consider the environment when choosing how to heat their homes.

In the largest cities of Britain, gas boilers are responsible for dangerous levels of atmospheric nitrogen dioxide emissions. In total, 14% of the UK’s greenhouse gases are produced by central heating systems.

Would choosing the Vokera Evolve C 18S system be an environmentally-friendly choice? If so, let's look at its performance figures.

By law, boilers manufactured and supplied in the UK must achieve a SEDBUK rating of "A" and work at a 92% minimum efficiency. Before April 2018, a minimum of 88% energy efficiency needed to be achieved (88/89% = SEDBUK "B" and 90% = SEDBUK "A").

Following official testing, the Vokera Evolve C 18S was given an efficiency rating of 94% with a SEDBUK rating of "A".

Energy efficiency is a measure of how much energy is used and how much is wasted when a boiler is operating.

Am I covered if the Vokera Evolve C 18S system boiler breaks down?

The Vokera Evolve C 18S boiler is provided with a parts and labour warranty lasting 10 years.
