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

The Vokera Evolve C 24S is an option you may wish to consider if you’re looking for a system boiler for your house or flat.

System boilers share many similarities with more traditional heat only boilers, like the need to program the times you want them to provide you with heat and hot water - just use the control panel to do this.

Where they differ from regular boilers is that they do not require a separate cold-water tank - everything is done within the hot water cylinder, which contains built-in circulating pumps. This makes them easier to install as there is one less component to fit and makes them more suitable for properties with no loft space, smaller lofts or for homeowners who are considering converting their loft.

As long as you have programmed your system boiler in advance, you will have the hot water you need ready for whenever you want to use it. Once the water is heated, it will remain available, warm, inside the tank until it’s all used up. It will then draw more water from the mains to start heating so that it can provide heat and hot water for the times you've told the system boiler you need it.

Would the Vokera Evolve C 24S system be a suitable boiler for my house or flat?

It's best to choose a boiler whose size or "output" is right for your property. With boilers, however, size does not mean how big a boiler is, it means how much power it has.

A boiler’s output indicates the amount of power it can use when heating the water which it then sends to your taps and radiators. The higher the output rate, the more water it can heat.

If a boiler’s output is too low, there will be times when your hot water might not be as hot as you want it to be. If it is too high, you’ll likely be paying more than you need to for your gas.

Measured in kilowatts, the Vokera Evolve C 24S system's output level is 24 kW, so which types of property would this Vokera Evolve C 24S System boiler be an appropriate choice for?

An experienced boiler engineer would recommend that this Vokera Evolve C 24S System boiler would provide adequate heating and hot water for medium-sized homes and larger apartments with up to 10-15 radiators and two bathrooms.

What size is a Vokera Evolve C 24S boiler?

The Vokera Evolve C 24S occupies a space of 955 mm high by 489 mm wide and 333 mm deep.

Evolve C 24S – condensing or non-condensing?

The Vokera Evolve C 24S 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 24S system boiler environmentally friendly?

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.

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.

Will you be helping the environment if you decide to install a Vokera Evolve C 24S system in your home? Let’s look at 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 24S 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.

Does a Vokera Evolve C 24S system boiler come with a warranty period?

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