Vokera Evolve C 35S System Gas boiler frequently asked questions

What type of boiler is the Vokera Evolve C 35S - regular, system or combi?

If you’re looking for a system boiler for your house or flat, then the Vokera Evolve C 35S is one you may wish to consider.

System boilers need a hot water cylinder to work, which is normally situated in an airing cupboard or similar. However, unlike heat only boilers, system boilers don’t require a separate cold water tank, meaning they are a preferred option for some homeowners, especially those planning a loft conversion in the future.

They use (often built-in) circulating pumps to distribute hot water to your taps and radiators and installation is often easier from scratch with heat only boilers as there’s one less component (the water tank) to purchase and fit.

System boilers also need programming for heat and hot water and don’t offer this instantly. However, the cylinder can keep water hot for use afterwards so you shouldn’t have to wait around for your bath water so long as you set your timer and have it on long enough to heat the water you’ll need for the day.

Is a Vokera Evolve C 35S system boiler suitable for my house or flat?

You should make sure that the boiler you choose for your property is the right "size". And size doesn't mean its physical dimensions. Size means how much power it has - the "output".

A boiler's output level measures how much power it can use to provide you with the hot water you need for your radiators and taps. If a boiler has a high output rate, it can heat greater volumes of water.

If you choose a boiler with too low an output, you'll find that the water coming out of your taps and in your radiators won't be as hot as you want it to be. Choosing one whose output is too high means you'll pay more than you need to for the gas your boiler needs to work.

The Vokera Evolve C 35S system outputs at a maximum of 35 kW, so which types of property would this Vokera Evolve C 35S System boiler be appropriate for?

Most heating engineers would recommend that this Vokera Evolve C 35S System boiler would be suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


Dimensions of the Vokera Evolve C 35S boiler

The Vokera Evolve C 35S boiler is 955 mm high, 489 mm wide, and 408 mm deep.

Is the Vokera Evolve C 35S condensing or non-condensing?

The Vokera Evolve C 35S 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 35S system good for the environment?

The effects of climate change on the environment are leading many homeowners to question the damage they might be doing by the way they 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.

Will choosing a Vokera Evolve C 35S system boiler for your home be positive for the environment? Let's examine the figures.

Boilers manufactured after April 2018 in the UK must achieve an "A" on the SEDBUK grading system as well as score a minimum of 92% on a separate energy efficiency test. Prior to that, the minimum was 88% - boilers rated at 88% and 89% were given a “B” rating (90% and higher were given an "A").

An energy efficiency rating describes how much energy the boiler uses and how much it wastes when in use.

The Vokera Evolve C 35S was awarded an efficiency rating of 94% with a SEDBUK grading of "A".

How long is the warranty period on a Vokera Evolve C 35S system boiler?

Vokera’s Evolve C 35S boiler includes a parts and labour warranty of 10 years.

Vokera Evolve C 35S System Gas boiler frequently asked questions

Is this Vokera Evolve C 35S boiler a combi, system or regular boiler?

The Vokera Evolve C 35S boiler is an option you may wish to consider if you're looking for a system boiler for your house or flat.

As with a heat only boiler, a system boiler requires the installation of a hot water cylinder but they do not need a cold water tank to work. This makes them suitable choices for homeowners planning a loft conversion or for properties without a loft or very limited attic space.

The primary heating and hot water system components are built in to system boilers and you can use the control panel to set the times that you wish your heating and hot water to be available. Hot water is stored in the cylinder for use throughout the day, but if you don't set your timer, heat and hot water will not be available instantly.

A system boiler can supply multiple taps and showers simultaneously and is suitable for both large families and properties with more than one bathroom - combi boilers struggle to do this.

Should I install a Vokera Evolve C 35S system boiler in my house or apartment?

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

This Vokera Evolve C 35S System boiler gets its power from gas and the power it's capable of producing is measured in kilowatts - the output rate is actually a kilowatt rate. The higher the output rate, the more kilowatts a boiler can use when heating water.

If you choose a boiler whose output rate is too low, it may not have enough power to make your water as hot as you would like. If you choose a boiler whose output rate is too high, you won't have to put up with lukewarm water but you will face higher gas bills.

The Vokera Evolve C 35S system boiler has an output level of 35 kW, so which types of property would it be appropriate for?

A PlumbProud Gas Safe boiler installer would recommend that the most suitable type of property for this Vokera Evolve C 35S System boiler would be larger properties including detached homes containing 15 or more radiators and two or more bathrooms.


How large is a Vokera Evolve C 35S boiler?

The Vokera Evolve C 35S measures 955 mm in height and has a width of 489 mm and a depth of 408 mm.

Is the Vokera Evolve C 35S non-condensing or condensing?

The Vokera Evolve C 35S 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.

How does the Vokera Evolve C 35S system boiler rate environmentally?

The effects of climate change on the environment are leading many homeowners to question the damage they might be doing by the way they heat their homes.

The heating of our homes accounts for 14% of the UK's greenhouse gas emissions. Especially in the big cities, gas boilers are responsible for dangerous levels of nitrogen dioxide emissions.

Is the Vokera Evolve C 35S system an environmentally friendly choice for your home? Let’s have a look at the figures.

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 35S was awarded an efficiency rating of "94%", equivalent to a "A" rating on the SEDBUK system.

What length of warranty does the Vokera Evolve C 35S come with?

The parts and labour warranty on the Vokera Evolve C 35S covers all repair-related costs for 10 years while the heat exchange warranty covers you for [Heat Exchange Warranty] years.
