Vokera Evolve C 42C Combi Gas boiler frequently asked questions

What type of boiler is the Vokera Evolve C 42C?

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

Boilers traditionally required the installation of one or more large tanks around your property. These were filled with water that was either being heated or was to be heated later. British homes are among the smallest in the world so, to solve the space problem, manufacturers introduced combi boilers in the 1970s to offer homeowners the warmth and hot water supply they needed while taking up much less space.

A combi boiler is designed to heat both radiators and taps on demand and at the same time. Water from the mains passes through a combi boiler and the boiler's technology instantly turns it into hot water. Your boiler then distributes the hot water throughout your home.

The main disadvantage of combi boilers is that they have a maximum water volume capacity. What this means is that, if one person is using the shower while another uses a hot tap simultaneously, less water gets to each area, resulting in a fall in water pressure at both points.

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

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

The output rating indicates how much energy a boiler can use in providing you with hot water and heat when you need it from your radiators and taps. The greater the output, the more water it can heat.

It's better to take advice on this from a registered installer because, if your boiler output is too low, your water and radiators might not get as hot as you would like them to be. However, if the output level is too high, you'll end up paying more on your gas bills than you need to.

Which types of property would this Vokera Evolve C 42C Combi boiler be appropriate for given its output of 42 kW?

A PlumbProud Gas Safe boiler installer would recommend that this Vokera Evolve C 42C Combi boiler is appropriate for larger properties including detached homes with 15 or more radiators and two or more bathrooms.

With combi boilers like the Vokera Evolve C 42C, you need to take the flow rate into account as well as the output rate.

Combi boilers draw water from the mains and then instantly heat that water and send it to wherever in your home it's needed. Flow rates, measured in litres per minute, are subject to the mains water pressure in your area. So, for example, if the local mains water pressure is 11 litres per minute and the flow rate of your boiler is 14 litres per minute, the boiler will not be able to process more than 11 litres per minute. The flow rate of this Vokera Evolve C 42C Combi boiler is TBCl/m.

If you live in a home with lots of radiators or bathrooms where many people want to use hot water at the same time, a combi boiler may not be able to cope. For reference, a power shower uses about 10 litres of water per minute. If two people want showers at the same time or one person wants a shower and the other hot water from a tap in the kitchen, your boiler may not have a large enough flow rate even if the local mains water pressure is high.

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 dimensions of the Vokera Evolve C 42C are

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

Evolve C 42C – non-condensing or condensing?

This Vokera Evolve C 42C is a condensing gas boiler - we always recommend that clients choose the latest condensing models to benefit from the technology, which continues to improve year after year.

Condensing boilers capture the heat still present in flue exhaust gases and water vapour condensation, processing them through a secondary heat exchanger to, among other tasks, heat colder water returning from your radiators.

By selecting a modern condensing boiler, you'll save money on your gas bills as well as benefitting the wider environment.

How energy efficient is the Vokera Evolve C 42C combi?

How we heat our homes is an issue which many homeowners worry about as the world combats climate change and environmental damage.

Central heating creates 14% of the UK’s greenhouse gases. And in Britain's larger cities, gas boilers are responsible for dangerous levels of nitrogen dioxide emissions.

Do the available figures suggest that installing the Vokera Evolve C 42C combi in your property would be an environmentally friendly choice?

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 42C was awarded an efficiency rating of "94%", equivalent to a "A" rating on the SEDBUK system.

Does the Vokera Evolve C 42C combi boiler come with a warranty?

The Vokera Evolve C 42C boiler is provided with a parts and labour warranty lasting 10 years.

Vokera Evolve C 42C Combi Gas boiler frequently asked questions

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

The Vokera Evolve C 42C boiler is an option you may wish to consider if you're looking for a combi boiler for your house or flat.

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.

Would the Vokera Evolve C 42C combi boiler be suitable for my house or flat?

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.

Boiler output is measured in kilowatts and tells you how much power a boiler can use to heat the water your taps, showers and radiators need. The higher the output, the more power it has.

When choosing a boiler, you should choose one that can cope with the peak demand for hot water in your home and not just your typical usage.

If its output is too low, sometimes your hot water will not be hot enough, but if your boiler's output is too high for your needs, your gas bills will go up and not down.

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

To most experienced Gas Safe boiler installers, the Vokera Evolve C 42C combi Evolve C would be most suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.

If you are considering installing a combi boiler in your home, you need to consider the flow rate as well as the output rate.

The flow rate is the volume of water (measured in litres per minute) that your boiler can instantly heat up and send around the home. The more demand in your home for water at the same time (for example, two people taking showers in different bathrooms), the higher the flow rate you'll need.

However, the actual flow rate your boiler can deliver is also determined by your mains water pressure. If you choose a boiler with a flow rate of 16l/m but the mains water pressure is 12l/m, your boiler will only perform to 12l/m. This Vokera Evolve C 42C Combi boiler's flow rate is TBCl/m.

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.


Where will the Vokera Evolve C 42C fit in my house?

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

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

We strongly recommend that you choose a condensing boiler like the Vokera Evolve C 42C - 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 42C combi rated as environmentally friendly?

How we heat our homes is an issue which many homeowners worry about as the world combats climate change and environmental damage.

14% of the UK’s greenhouse gas production comes from central heating. In the bigger cities, gas boilers in particular are responsible for dangerous levels of nitrogen dioxide emissions.

Will choosing a Vokera Evolve C 42C combi boiler for your home be positive for the environment? Let's examine the figures.

Every boiler manufactured and supplied in the UK must have an energy efficiency rating of 92% (SEDBUK “A” rating). These minimums were made law in April 2018 - before that, the minimum energy efficiency rating was 88% (88%/89% = "B" SEDBUK grade, 90%+ = "A" SEDBUK grade).

The Vokera Evolve C 42C was awarded an efficiency rating of 94% and a band rating of "A".

Energy efficiency ratings for boilers describe the amount of energy they use and waste when switched on and working.

If the Vokera Evolve C 42C breaks down, will I be covered by the warranty?

The parts and labour warranty on the Vokera Evolve C 42C lasts for 10 years.
