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

Which category of boiler does the Ariston CLAS HE SYSTEM EVO 30 fit into?

You may wish to consider installing the Ariston CLAS HE SYSTEM EVO 30 if you are looking for a system boiler for your house or flat.

System boilers require a hot water cylinder to work (normally stored in an airing or landing cupboard) but, unlike heat only boilers, they do not require a cold water tank. This makes them more suitable for homes that do not have lofts, where attic space is limited or where a loft conversion is being considered.

You program your heating and hot water to come on via the control panel. But if you forget to set the timer, you will have to wait a while for the water to heat up. Hot water is stored in the cylinder for use throughout the day and can be distributed to multiple showers and taps at the same time without a loss of pressure or temperature (something combi boilers really struggle with). For this reason, a system boiler is a suitable option for large families and homes with more than one bathroom.

As no cold-water tank is needed with a system boiler and many major system components are built into it, this type of boiler can be easier to install than a standard boiler.

Is a Ariston CLAS HE SYSTEM EVO 30 system the right boiler for my house or flat?

Selecting the right boiler for your property means selecting a boiler that is the right "size". And, by size, we don't mean how big it is, we mean how powerful it is - its "output".

The output rate tells you how much energy your boiler has to use to provide you and your family with hot water and central heating. A higher output rate means that it can heat greater volumes of water.

Please be aware, though - if you choose a boiler whose output is too low, the water in your radiators and coming from your taps may not be warm enough. Conversely, if you choose a boiler with too high an output, you'll pay more for gas than is necessary.

The Ariston CLAS HE SYSTEM EVO 30 system boiler has an output level of 30 kW, so which types of property would it be appropriate for?

A Gas Safe boiler installer would recommend that, at this level of output, the most suitable type of property for this Ariston CLAS HE SYSTEM EVO 30 System boiler would be larger properties including detached homes with 15 or more radiators and two or more bathrooms.


What size is the Ariston CLAS HE SYSTEM EVO 30 boiler?

The Ariston CLAS HE SYSTEM EVO 30 is TBC mm high by TBC mm wide by TBC mm deep.

Is the Ariston CLAS HE SYSTEM EVO 30 a condensing or non-condensing boiler?

We strongly recommend that you choose a condensing boiler like the Ariston CLAS HE SYSTEM EVO 30 - 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.

Does the Ariston CLAS HE SYSTEM EVO 30 system protect the environment?

Price and performance are two important issues when choosing a boiler but now, for many people in the UK, so is the environmental impact of how we heat our homes and its effect on climate change.

We generate 14% of UK greenhouse gas emissions through centrally heating our domestic properties. Gas boilers are mainly responsible for harmful nitrogen dioxide emissions in larger British cities.

Would installing a Ariston CLAS HE SYSTEM EVO 30 system boiler in your home help combat climate change? What do the figures suggest?

All new British boilers must perform to a legal minimum energy efficiency of 92% (a low to good SEDBUK "A" rating). Prior to April 2018, the target was 88% (86-90% = SEDBUK "B" and 90%+ = SEDBUK "A").

Efficiency ratings are intended to let consumers know how much energy a boiler uses in its day-to-day activities and how much energy goes to waste.

The Ariston CLAS HE SYSTEM EVO 30 was awarded an efficiency rating of 90%, equivalent to a SEDBUK grade of "A".

What is the warranty period for the Ariston CLAS HE SYSTEM EVO 30?

The parts and labour warranty on the Ariston CLAS HE SYSTEM EVO 30 covers all repair-related costs for 5 years while the heat exchange warranty covers you for [Heat Exchange Warranty] years.

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

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

The Ariston CLAS HE SYSTEM EVO 30 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.

Is the Ariston CLAS HE SYSTEM EVO 30 system 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.

The output rate of a boiler tells you how much power it has available to it for heating the water that comes out of your taps and warms your radiators. A higher output rate means that your boiler has more power at its disposal.

You need to make sure you select a boiler with the right output rate. That's because, if your output rate is too high, then your boiler will have more power than it needs but it will cost too much to run. If the output rate is too low, your water may often not be hot enough.

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

Most Gas Safe engineers would suggest that the Ariston CLAS HE SYSTEM EVO 30 system boiler would be a suitable choice for installation in larger properties including detached homes with 15 or more radiators and two or more bathrooms.


What size is the Ariston CLAS HE SYSTEM EVO 30 boiler?

The Ariston CLAS HE SYSTEM EVO 30 is TBC mm [H] by TBC mm [W] by TBC mm [D] in size.

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

This Ariston CLAS HE SYSTEM EVO 30 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.

Is the Ariston CLAS HE SYSTEM EVO 30 system boiler environmentally friendly?

How we heat our homes has become a major issue for many people worried about climate change and environmental issues in general.

In the UK, central heating systems account for 14% of greenhouse gas production. Gas boilers in particular are responsible for emissions of dangerous nitrogen dioxide in British cities.

Do the available figures suggest that installing the Ariston CLAS HE SYSTEM EVO 30 system in your property would be an environmentally friendly choice?

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 Ariston CLAS HE SYSTEM EVO 30 is rated as 90% energy efficient, equivalent to a "A" SEDBUK rating.

Will I be covered if the Ariston CLAS HE SYSTEM EVO 30 system breaks down?

You receive a parts and labour warranty of 5 years with the Ariston CLAS HE SYSTEM EVO 30 boiler.
