Vokera Evolve C 42C Combi Gas boiler frequently asked questions

Is the Vokera Evolve C 42C boiler a combi, system or regular boiler?

Looking for a gas combi boiler for your house or flat? If you are, the Vokera Evolve C 42C boiler may be worth considering.

Traditional boilers often have up to two tanks that either store heated water or water to be heated later. Boiler manufacturers introduced combi boilers in the 1970s to avoid the need for those big tanks. Combi boilers allow homeowners to benefit from the reliable central heating and hot water level they want but without having to give up so much space within their properties - remember that homes in the UK are among the smallest in the developed world.

Your taps and radiators get the hot water they need with a combi boiler. Combi boilers draw cold water direct from the mains which is then heated instantly on demand and distributed to your radiators and taps.

However, combi boilers cannot heat very large volumes of water, which is their main disadvantage. So, for example, when someone wants to take a shower while another person wants to use a hot water tap to do the dishes, water pressure and quantity to both points decreases.

Is a Vokera Evolve C 42C combi boiler suitable for my apartment or house?

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 42C combi boiler has an output level of 42 kW, so which types of property would it be appropriate for?

Most experienced Gas Safe engineers would likely recommend that, at this level of output, this Vokera Evolve C 42C Combi boiler would be a suitable choice for larger properties including detached homes with 15 or more radiators and two or more bathrooms.

As well as the output rate, you need to consider "flow rate" when choosing a combi boiler.

The flow rate describes how much water a combi boiler can draw from the mains, instantly heat, and then send to your radiators. Flow rates are measured in litres per second and this Vokera Evolve C 42C Combi boiler's flow rate is TBCl/m.

The water in your mains pipe also has its own flow rate - normally between 10 and 12l/m in most parts of Britain. This means that, if you choose a combi boiler with a flow rate of 17l/m where local water pressure is 11lm, it won't actually process more water because of the slower flow rate of the mains.

In addition, larger households with more than one bathroom, multiple radiators, and where family members may want to use hot water at the same time (like morning showers) may actually need a boiler with a higher flow rate than either the boiler or the local mains pipe.

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 dimensions does a Vokera Evolve C 42C have?

The Vokera Evolve C 42C occupies a space of 955 mm high by 469 mm wide and 408 mm deep.

Is the Vokera Evolve C 42C condensing or non-condensing?

Condensing gas boilers like the Vokera Evolve C 42C are more energy-efficient and choosing one for your home will cut the amount you pay every year for your gas.

They do this by capturing the heat in water vapour condensation and in exhaust gases which would normally be expelled via the flue. They then recycle that heat, returning it to the system to, among other tasks, reheat colder water that is returning to your boiler from your radiators.

Is the Vokera Evolve C 42C combi rated as environmentally friendly?

Environmentally-friendly heating has become an important issue for homeowners concerned about the accelerating pace of climate change.

Gas boilers are responsible for dangerous atmospheric levels of nitrogen dioxide emissions in Britain's biggest cities and, overall, 14% of the UK’s greenhouse gases are produced by our domestic central heating systems.

Will installing a Vokera Evolve C 42C combi be a positive contribution to the environment? Let's see what the experts say.

All boilers manufactured and supplied in the UK are assigned two energy efficiency ratings. By law, they must achieve a SEDBUK "A" rating subject to a minimum efficiency level of 92%. Prior to that, the minimum was 88% (88% and 89% are equivalent to a SEDBUK "B" grade and 90% and above an "A" grade).

The ratings awarded to the Vokera Evolve C 42C are 94% with a SEDBUK rating of "A".

How long is the warranty period on a Vokera Evolve C 42C combi boiler?

The Vokera Evolve C 42C is covered by a parts and labour warranty of 10 years following installation.

Vokera Evolve C 42C Combi Gas boiler frequently asked questions

Is the Vokera Evolve C 42C a system boiler, a combi boiler or a regular boiler?

The Vokera Evolve C 42C boiler could be suitable for your house or flat if you are looking for a new combi boiler.

Traditionally, boilers needed one or more large tanks installed in your property to store their heated water or water that was to be heated later. These tanks were often too large to be practical for most homes so the combi boiler was introduced to Britain in the 1970s by manufacturers to help homeowners overcome this issue.

Instead of using tanks as storage, a combi boiler heats water on demand. It draws water from the mains and heats it instantly on demand before distributing it to wherever it is needed in a property, be it your taps or radiators.

Unfortunately, combi boilers have one main disadvantage for larger properties or larger households. Because they have a maximum volume of water that can be heated on demand at any given time, water pressure, volume and temperature will drop if, for example, someone is taking a shower and another person in your home wants to use a hot water tap at the same time.

Is a Vokera Evolve C 42C combi the right boiler for my house or flat?

Whether this Vokera Evolve C 42C Combi boiler is right for where you live depends on its size or "output" level. Size does not mean its physical dimensions, however - it means how powerful it is.

Measured in kilowatts, a boiler's output level is an indication of the amount of power it has available to it to heat the water coming from your taps and for warming your radiators. The greater the output level, the more water it can heat.

If you choose a boiler whose output level is too low, you'll often find that the water is not as hot as you want it to be. If you choose a boiler whose level is too high, you'll be paying higher gas bills than you need to for years to come.

The output of the Vokera Evolve C 42C combi is 42 kW, so which types of property is this Vokera Evolve C 42C Combi boiler appropriate for?

Most Gas Safe boiler installers would recommend that a boiler with this output level would be most suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.

Homeowners considering fitting a combi boiler to their home need to consider flow rates as well as output rates.

The flow rate is a measurement of the volume of water a combi can instantly heat and send to the taps and radiators around your home. The higher the likely demand for hot water in your home, the higher your combi's flow rate should be. This Vokera Evolve C 42C Combi boiler's flow rate is TBCl/m.

Unlike heat only or system boilers, combi boilers don't store hot water in a tank for later use - instead, they draw it directly from the mains. This means that the volume of water your boiler can actually process is constrained by the flow rate of water in the mains pipe.

So, if you choose a combi boiler with a 15l/m flow rate but the flow rate in your mains pipe is 12l/m, the combi boiler's working flow rate is also 12l/m.

Combi boilers are also not always the correct choice for homes with multiple bathrooms, a high number of radiators, or where more than one family member will want to use hot water at the same time.

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 large is a Vokera Evolve C 42C boiler?

The Vokera Evolve C 42C stands at 955 mm tall, 469 mm wide and 408 mm deep.

Is this Vokera boiler non-condensing or condensing?

The Vokera Evolve C 42C is a condensing gas boiler - we strongly suggest that you choose either this model or a recently released model if at all possible.

A condensing boiler captures and recycles the warmth present in flue exhaust gases and water vapour condensation created by the burning of gas to warm up the water coming back into your boiler - for example, from your radiators.

Condensing boilers cost less to run (lower gas bills) and are better for the environment.

Is the Vokera Evolve C 42C combi good for the environment?

With growing concern among the public about accelerating climate change, how we heat our homes and the impact this has on the environment has become a major topic of concern for many homeowners.

In the UK, central heating is responsible for 14% of greenhouse gas production. Domestic gas boilers emit large quantities of nitrogen dioxide in British cities.

Would choosing the Vokera Evolve C 42C combi boiler be an environmentally friendly decision? Here's what the figures say.

In the UK, by law, all boilers manufactured since April 2018 must have a SEDBUK “A” rating and operate to a minimum level of 92% energy efficiency. Prior to this, the minimum was 88% – 88/89% would score a "B" and 90% or more an "A" on the SEDBUK scale.

The energy efficiency rating measures the amount of energy a boiler consumes when it's in use and how much it loses on non-core operations.

Following testing, the Vokera Evolve C 42C was given an efficiency rating of 94% and a SEDBUK grading of "A".

What is the length of the warranty on the Vokera Evolve C 42C?

On the Vokera Evolve C 42C, the manufacturer offers a parts and labour warranty of 10 years.
