Vokera Evolve C 35S System Gas boiler frequently asked questions

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

The Vokera Evolve C 35S boiler is a system boiler you may wish to consider when looking for a new boiler for your house or flat.

A system boiler needs a hot water cylinder to work but it does not require a cold water tank, unlike with heat only boilers. This makes system boilers suitable for properties that lack loft space (or have no loft at all) or where a loft conversion is planned. The cylinder stores hot water for use throughout the day and water can be distributed to more than one tap or shower simultaneously without a loss of pressure or temperature (something combi boilers really struggle with).

System boilers are generally found in larger homes or properties housing large families. System boilers are easier to install than heat only boilers because their major components, including the circulation pump, are built-in and, of course, no cold water tank is needed.

With a system boiler, you use the control panel to set times for when you want the heating and hot water to be available but, unlike combi boilers, they cannot deliver hot water instantly. If you don't set your timer, you will have to wait for the water to heat up.

Should I choose a Vokera Evolve C 35S system boiler for my house or flat?

You should make sure that the boiler you install in your property is the right "size". And, by size, we don't mean how big it is, we mean how powerful it is - the "output".

Your boiler has to be powerful enough to heat all the hot water you need for your radiators and taps. Power is measured in kilowatts and the more kilowatts a boiler has available to it, the more water it can heat.

If the output (measured in kilowatts) is too high, you'll have all the power you need and more but your gas bills will be much higher. If it's too low, you'll often find that the water coming out of your taps and fed into your radiators is only lukewarm.

With the Vokera Evolve C 35S system's output at 35 kW, which types of property would this Vokera Evolve C 35S System boiler be most appropriate for?

A Gas Safe boiler installer would recommend that this Vokera Evolve C 35S System boiler would be a suitable choice for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


How big is the Vokera Evolve C 35S?

The Vokera Evolve C 35S is 955 mm high by 489 mm wide by 408 mm deep.

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

The Vokera Evolve C 35S is a condensing gas boiler - this is the type of boiler we recommend to most clients because they're better for the environment and they will save money on annual fuel bills.

A condensing boiler captures and recycles the warmth still present in both the flue exhaust gases and water vapour condensation created when gas is burned to provide your boiler with power.

This means it needs less gas to operate and it uses this extra energy to perform a number of tasks, including heating the colder water that comes back to the boiler from the radiators in your home.

Is the Vokera Evolve C 35S system environmentally friendly?

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.

14% of the total amount of greenhouse gases produced by the UK comes from the central heating systems we use. In some of Britain's biggest cities, gas boilers create dangerous levels of nitrogen dioxide in the atmosphere.

Will choosing to install a Vokera Evolve C 35S system in your home help the environment? Let's review the figures.

All boilers manufactured and supplied in the UK must achieve an energy efficiency rating of at least 92% (an "A" SEDBUK grade). This is higher than the previous 88%, which was a legal requirement prior to April 2018.

The energy efficiency rating is used to work out how much energy a boiler both uses and wastes when it's switched on and working correctly - its standard functioning and operation.

The Vokera Evolve C 35S is rated as 94% energy efficient, equivalent to a "A" SEDBUK rating.

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

The Vokera Evolve C 35S boiler comes with a parts and labour warranty of 10 years.

Vokera Evolve C 35S System Gas boiler frequently asked questions

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

If you want a system boiler for your flat or house, the Vokera Evolve C 35S might be an option for you to consider.

This type of boiler is better for larger homes and larger families where the demand for water is likely to be higher.

System boilers use a cylinder that draws water from the mains, heats it and then keeps it warm. The cylinder stores a large amount of water, meaning that you should have hot water all day. To be certain of this, make sure that you program your boiler to draw and heat water to meet times when demand is greater, like first thing in the morning before you and your family members go to work or school, and for the evening when everyone gets home.

Unlike heat only boilers, you won't need to find room in your attic for a cold water storage tank - suitable if you don't have an attic, your attic space is very limited, or you are planning an attic conversion in the near future.

Is the Vokera Evolve C 35S system boiler a suitable option 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?

A PlumbProud heating engineer would recommend that this Vokera Evolve C 35S System boiler be installed in larger properties including detached homes with 15 or more radiators and two or more bathrooms.


Making space for the Vokera Evolve C 35S

The Vokera Evolve C 35S occupies a space of 955 mm high by 489 mm wide and 408 mm deep.

Is this Vokera boiler condensing or non-condensing?

Condensing gas boilers like the Vokera Evolve C 35S 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 35S system an environmentally friendly boiler?

With environmental issues in the spotlight, more and more homeowners are becoming concerned about how they heat their homes and how much they're contributing towards combatting climate change.

About 14% of the greenhouse gases we produce in the UK come from the power needed for central heating. In bigger British cities, gas boilers are a significant source of nitrogen dioxide emissions.

Do the available figures suggest that installing the Vokera Evolve C 35S system in your property would be an environmentally friendly choice?

The energy efficiency rating of the Vokera Evolve C 35S 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).

What warranty does the Vokera Evolve C 35S system boiler 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.
