Vokera Evolve C 24C Combi Gas boiler frequently asked questions

What type of boiler is Vokera’s Evolve C 24C - system, regular or combi?

When looking for a combi boiler for your house or flat, the Vokera Evolve C 24C might be a suitable option for you.

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 Vokera Evolve C 24C combi boiler the right choice for my house or apartment?

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 - its "output".

The output rate tells you how much energy your boiler has to use to provide you and your family with hot water and central heating. A higher output rate means that it can heat greater volumes of water.

Please be aware, though - if you choose a boiler whose output is too low, the water in your radiators and coming from your taps may not be warm enough. Conversely, if you choose a boiler with too high an output, you'll pay more for gas than is necessary.

The Vokera Evolve C 24C combi boiler has an output level of 24 kW, so which types of property would it be appropriate for?

Most experienced boiler engineers would recommend this Vokera Evolve C 24C Combi boiler as a suitable option for smaller homes and apartments with no more than 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 Vokera Evolve C 24C 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 Vokera Evolve C 24C 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.


What size is the Vokera Evolve C 24C boiler?

The Vokera Evolve C 24C is 955 mm tall, 489 mm wide, and 333 mm deep.

Is the Vokera Evolve C 24C 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 24C 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 24C combi boiler an environmentally friendly choice?

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 produces 14% of all greenhouse gas emissions in the UK. Gas boilers in the larger cities emit dangerous levels of nitrogen dioxide.

Would installing a Vokera Evolve C 24C combi boiler in your home help combat climate change? What do the figures suggest?

An energy efficiency rating of 92% or above is a legal requirement for all boilers manufactured and installed in the UK today. 92% is equivalent to a low-to-middle "A" grade on the "Seasonal Efficiency of Domestic Boilers" (SEDBUK) scale.

Energy efficiency measures how much energy a boiler uses and wastes in the course of its normal operation. The lower the waste, the lower your gas bills.

The Vokera Evolve C 24C was awarded an efficiency rating of "94%", equivalent to a "A" rating on the SEDBUK system.

What is the warranty period on a Vokera Evolve C 24C combi boiler?

The Vokera Evolve C 24C boiler comes with a 10 year warranty for parts and labour.

Vokera Evolve C 24C Combi Gas boiler frequently asked questions

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

Suitable for a house or a flat, the Vokera Evolve C 24C combi boiler is worth considering if you want a combi boiler.

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 Vokera Evolve C 24C combi boiler suitable for my apartment or house?

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

The output rate of a boiler tells you how much power it has available to it for heating the water that comes out of your taps and warms your radiators. A higher output rate means that your boiler has more power at its disposal.

You need to make sure you select a boiler with the right output rate. That's because, if your output rate is too high, then your boiler will have more power than it needs but it will cost too much to run. If the output rate is too low, your water may often not be hot enough.

The Vokera Evolve C 24C combi's output is 24 kW, so which types of property would this Vokera Evolve C 24C Combi boiler be appropriate for?

To most experienced Gas Safe engineers, the Vokera Evolve C 24C combi Evolve C would be most suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

If you are thinking about installing a combi boiler like the Vokera Evolve C 24C in your home, you should consider flow rates as well as output rates. This Vokera Evolve C 24C 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.


The size of the Vokera Evolve C 24C

The Vokera Evolve C 24C is 955 mm tall, 489 mm wide, and 333 mm deep.

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

Because of their increased energy efficiency, we recommend to all customers that they select one of the latest condensing boilers. Condensing boilers capture the heat from water vapour condensation and flue exhaust gases and recycle that heat to warm water entering the boiler (for example, from your radiators).

The Vokera Evolve C 24C is a condensing gas boiler and choosing this model will result in a likely substantial reduction in your fuel bills, particularly if you're replacing an older, inefficient, non-condensing boiler.

Is the Vokera Evolve C 24C combi good for the environment?

Concern for the environment is causing more and more homeowners to think about how they heat their homes and its impact on climate change.

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.

Will installing a Vokera Evolve C 24C combi be a positive contribution to the environment? Let's see what the experts say.

The energy efficiency rating for a boiler describes the amount of energy it uses and wastes during operation and there are two different ways to measure it.

All boilers manufactured and supplied in the UK must have a SEDBUK rating of “A” subject to a minimum energy efficiency score of 92% or above. Before April 2018, the minimum energy efficiency score was 88% (88/89% = "B" SEDBUK rating, 90%+ = "A" SEDBUK rating).

The Vokera Evolve C 24C scored an efficiency rating of 94% and a SEDBUK band rating of A.

What warranty do I get if I purchase the Vokera Evolve C 24C boiler?

The Vokera Evolve C 24C boiler is covered by a parts and labour warranty of 10 years.
