Ariston CLAS HE SYSTEM EVO 30 System Gas boiler frequently asked questions

Ariston CLAS HE SYSTEM EVO 30 - combi, system or regular boiler?

The Ariston CLAS HE SYSTEM EVO 30 is worthy of consideration if you're looking for a system boiler for your flat or house.

System boilers need a hot water cylinder to work, with the most popular installation location for cylinders being in an airing or landing cupboard. Unlike heat only boilers though, they don't require a separate cold water tank to go in the attic, making them suitable if roof space is at a premium or if you're planning a loft conversion in the future.

System boilers use (often built-in) circulating pumps to distribute hot water to your taps and radiators. Fitting is cheaper and quicker too because you don't need to find room for a water tank. Unlike with a combi boiler, which heats water it draws from the mains instantly, you have to program a system boiler with the times you want hot water and heating.

Is the Ariston CLAS HE SYSTEM EVO 30 system boiler from the CLAS HE SYSTEM EVO range a suitable choice for my house or flat?

Whether this Ariston CLAS HE SYSTEM EVO 30 System boiler is right for where you live 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 of a boiler is measured in kilowatts and indicates how much energy it can use to heat the water needed for your radiators, taps and showers. The greater the output, the more water it can heat.

A boiler whose output is too high will give you hot water and warm radiators but also higher gas bills, whereas a boiler whose output is too low will result in cheaper gas bills but the water might not always be as hot as you want it to be.

The output of the Ariston CLAS HE SYSTEM EVO 30 system is 30 kW, so which types of property would this model be appropriate for?

A Gas Safe engineer would recommend that the Ariston CLAS HE SYSTEM EVO 30 system boiler would be an ideal installation option for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


What dimensions does a Ariston CLAS HE SYSTEM EVO 30 have?

The Ariston CLAS HE SYSTEM EVO 30 has the following dimensions - TBC mm high, TBC mm wide, and TBC mm deep.

Ariston CLAS HE SYSTEM EVO 30 – condensing or non-condensing?

We recommend that you select a condensing boiler like the Ariston CLAS HE SYSTEM EVO gas Ariston CLAS HE SYSTEM EVO 30 for your home if possible because of the environmental benefits and the money you'll save on your gas bills.

Condensing boilers are much more energy-efficient than older, non-condensing models as they capture and recycle the heat still present in the water vapour condensation and flue exhaust gases that your boiler creates when burning gas for reuse.

How energy efficient is the Ariston CLAS HE SYSTEM EVO 30 system boiler?

How we heat our homes and the effect that has on climate change has become important to many homeowners worried about the environment.

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.

Will choosing a Ariston CLAS HE SYSTEM EVO 30 system boiler for your home be positive for the environment? Let's examine the figures.

The energy efficiency rating for a boiler describes the amount of energy it uses and wastes during operation and there are two different ways to measure it.

All boilers manufactured and supplied in the UK must have a SEDBUK rating of “A” subject to a minimum energy efficiency score of 92% or above. Before April 2018, the minimum energy efficiency score was 88% (88/89% = "B" SEDBUK rating, 90%+ = "A" SEDBUK rating).

The Ariston CLAS HE SYSTEM EVO 30 scored an efficiency rating of 90% and a SEDBUK band rating of A.

What warranty do I get if I purchase the Ariston CLAS HE SYSTEM EVO 30 boiler?

The Ariston CLAS HE SYSTEM EVO 30 boiler is provided with a parts and labour warranty lasting 5 years.

Ariston CLAS HE SYSTEM EVO 30 System Gas boiler frequently asked questions

Ariston CLAS HE SYSTEM EVO 30 - a system boiler, regular boiler or combi boiler?

If you want a system boiler for your flat or house, the Ariston CLAS HE SYSTEM EVO 30 might be an option for you 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.

Should I install a Ariston CLAS HE SYSTEM EVO 30 system boiler in my home?

Whether this Ariston CLAS HE SYSTEM EVO 30 System boiler is right for where you live depends on its size or "output" level. Size does not mean its physical dimensions - it means how powerful it is.

A boiler’s output is a measurement of the amount of power it can use to provide hot water to your taps and radiators. The higher its output rate, the more water it can heat.

If your new boiler’s output is too low, your hot water might not be as hot as you want it to be. If it's too high, you’ll be paying more for gas than you need to.

The output of the Ariston CLAS HE SYSTEM EVO 30 system boiler is 30 kW, so which types of property would this be appropriate for?

An experienced PlumbProud Gas Safe engineer would recommend that the level of output from this Ariston CLAS HE SYSTEM EVO 30 System boiler would make it a suitable installation option for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


How large is the Ariston CLAS HE SYSTEM EVO 30?

The size of the Ariston CLAS HE SYSTEM EVO 30 boiler is TBC mm tall, TBC mm wide, and TBC mm deep.

CLAS HE SYSTEM EVO 30 – condensing or non-condensing?

We recommend the Ariston CLAS HE SYSTEM EVO 30 as it is a modern condensing gas boiler from a trusted manufacturer with a reputation for supplying highly energy-efficient boilers.

Condensing boilers capture the heat still present in water vapour condensation and flue exhaust gases and recycle it back into the heating system. With this extra energy, your boiler can, among other tasks, reheat colder water coming back from your radiators without having to burn more gas.

Condensing boilers significantly reduce your quarterly gas costs and they're better for the environment.

Is the Ariston CLAS HE SYSTEM EVO 30 system a good choice for the environment?

How we heat our homes has become a pressing issue of concern for many homeowners worried about climate change and the environmental impact of their personal choices.

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.

Is the Ariston CLAS HE SYSTEM EVO 30 system an environmentally friendly choice for your home? Let’s have a look at the figures.

All boilers manufactured in the UK from April 2018 must operate at a minimum level of energy efficiency of 92% ("A" rating on the SEDBUK scale). Before that, the minimum was 88% - boilers scoring 88/89% were given a SEDBUK "B" rating and 90% or above an "A" rating.

The energy efficiency score of a boiler indicates how much energy it uses and how much goes to waste when in use.

After its assessment, the Ariston CLAS HE SYSTEM EVO 30 was given an efficiency rating of 90% and a SEDBUK grading of "A".

What warranty do I get if I purchase the Ariston CLAS HE SYSTEM EVO 30 boiler?

Parts and labour charges incurred during a repair on the Ariston Ariston CLAS HE SYSTEM EVO 30 boiler are covered by a 5 year warranty.
