Is the Vokera Evolve C 24C boiler a combi, regular or a system boiler?

If you’re looking for a combi boiler for your house or flat, then the Vokera Evolve C 24C is one you may wish to consider.

In the past, most boilers needed one or more storage tanks to operate - one to store warm water and the other for storing water to be heated later. But storage tanks are problematic in properties where space is at a premium and particularly where there is no loft. Many properties in the UK are small and so manufacturers introduced combi boilers in the 1970s to eliminate the need for tanks.

With a combi boiler, the hot water for your radiators and taps is delivered on demand. The boiler instantly heats water it draws directly from the mains internally. It then distributes the heated water around your home at mains pressure as you need it.

It is important to bear in mind that, while combi boilers have many benefits, they can only heat a certain volume of water at any given time. This means that, if you run a shower at the same time as someone else is doing the washing up in the kitchen, the volume of water passing to each point will drop, causing a fall in pressure.

Would the Vokera Evolve C 24C combi be a suitable choice of boiler for my house or flat?

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 24C Combi boiler be appropriate for given its output of 24 kW?

Most experienced heating engineers would likely recommend that, at this level of output, this Vokera Evolve C 24C Combi boiler would be a suitable choice for smaller homes and apartments with up to 10 radiators and one bathroom.

With combi boilers, flow rates are as important a consideration as output rates.

All combi boilers draw water from the mains. They then heat this water instantly whenever it's needed and distribute it to your radiators and taps.

A boiler's "flow rate" describes how much water a boiler can draw from the mains at any one time, which it then heats and sends around your home (measured in litres per minute). This Vokera Evolve C 24C Combi boiler's flow rate is TBCl/m.

If your home has a large number of radiators, a lot of bathrooms, or multiple people who wish to use the hot water at the same time, your combi boiler may not be able to draw as much water from the mains as it needs to serve everyone, regardless of how high the flow rate is.

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.

How big is the Vokera Evolve C 24C?

The Vokera Evolve C 24C measures 955 mm in height by 489 mm in width by 333 mm in depth.

Is the Vokera Evolve C 24C non-condensing or condensing?

We strongly recommend that you choose a condensing boiler like the Vokera Evolve C 24C - 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 Vokera Evolve C 24C combi boiler rated as 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 UK, central heating systems account for 14% of greenhouse gas production. Gas boilers in particular are responsible for emissions of dangerous nitrogen dioxide in British cities.

Would choosing the Vokera Evolve C 24C combi be an environmentally-friendly choice? If so, let's look at its performance figures.

The energy efficiency rating of the Vokera Evolve C 24C is 94% with a SEDBUK band rating of "A".

Energy efficiency tests record how much energy is wasted on non-core functions during an operation.

By law, all boilers manufactured and supplied in the UK must have a minimum energy efficiency performance level of 92% (equivalent to a SEDBUK "A" grade). Up to April 2018, the minimum performance level was 88% (88% and 89% are equivalent to a SEDBUK "B" grade and 90%+ an "A" grade).

How long is the warranty period on the Vokera Evolve C 24C combi boiler?

The parts and labour warranty offered with this Vokera Evolve C 24C Combi boiler covers you for 10 years.
