Ariston CLAS SYSTEM ONE 30 System Gas boiler frequently asked questions

Is the Ariston CLAS SYSTEM ONE 30 boiler a standard, combi or system model?

The Ariston CLAS SYSTEM ONE 30 may be worth considering if you are 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 SYSTEM ONE 30 system suitable 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 Ariston CLAS SYSTEM ONE 30 system's output at 30 kW, which types of property would this Ariston CLAS SYSTEM ONE 30 System boiler be most appropriate for?

An experienced Gas Safe boiler installer would be likely to recommend that this Ariston CLAS SYSTEM ONE 30 System boiler is capable of providing heating and hot water to 15 or more radiators and two or more bathrooms and would therefore be most suitable for larger properties including detached homes.


Ariston CLAS SYSTEM ONE 30 size

The Ariston CLAS SYSTEM ONE 30 is TBC mm tall, TBC mm wide, and TBC mm deep in size.

Is the Ariston CLAS SYSTEM ONE 30 condensing or non-condensing?

We strongly recommend that you choose a condensing boiler like the Ariston CLAS SYSTEM ONE 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.

What energy efficiency ratings have been awarded to the Ariston CLAS SYSTEM ONE 30 system?

Concern for the environment is causing more and more homeowners to think about how they heat their homes and its impact on 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.

Is the Ariston CLAS SYSTEM ONE 30 system boiler an environmentally friendly choice for your home? Here’s what the figures say.

Under current UK law, all boilers must achieve a minimum energy efficiency level of 92% (a low to good SEDBUK "A" rating). The minimum level was raised from its previous 88% in April 2018.

Energy efficiency scores are intended to inform consumers of the amount of energy used and wasted when a boiler is in normal operation.

The Ariston CLAS SYSTEM ONE 30 was awarded an efficiency rating of 90% with a SEDBUK band rating of "A".

What is the warranty period for the Ariston CLAS SYSTEM ONE 30?

You receive a parts and labour warranty of 8 years with the Ariston CLAS SYSTEM ONE 30 boiler.

Ariston CLAS SYSTEM ONE 30 System Gas boiler frequently asked questions

Is this Ariston CLAS SYSTEM ONE 30 boiler a combi, system or regular boiler?

Looking for a gas system boiler for your flat or house? Then the Ariston CLAS SYSTEM ONE 30 may be an option you should consider.

Ever since system boilers arrived on the market, they have been a popular choice in new homes. In the same way as regular boilers, they work along with a hot water cylinder, which is usually located in an airing cupboard. Since system boilers do not require a separate cold water tank, they appeal to some homeowners, especially if they intend to convert their loft in the future.

Their design includes (often built-in) circulating pumps to send hot water to your taps and radiators. They're also quicker and easier to install because you don't need to find room for and fit a water storage tank.

In addition, system boilers require programming for the flow of heat and hot water, which is not available right away. In any case, the cylinder keeps the water hot for use later, so you shouldn't have to wait for your bath as long as you set your timer and leave it on for long enough to heat sufficient water to use throughout the day.

Would the Ariston CLAS SYSTEM ONE 30 system be a suitable boiler for my house or flat?

Whether this Ariston CLAS SYSTEM ONE 30 System boiler is right for your property 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 rating indicates how much energy a boiler can use in providing you with hot water and heat when you need it from your radiators and taps. The greater the output, the more water it can heat.

It's better to take advice on this from a registered installer because, if your boiler output is too low, your water and radiators might not get as hot as you would like them to be. However, if the output level is too high, you'll end up paying more on your gas bills than you need to.

Which types of property would this Ariston CLAS SYSTEM ONE 30 System boiler be appropriate for given its output of 30 kW?

A heating engineer would recommend that this Ariston CLAS SYSTEM ONE 30 System boiler would provide adequate heating and hot water for larger properties including detached homes with up to 15 or more radiators and two or more bathrooms.


How big is the Ariston CLAS SYSTEM ONE 30?

The Ariston CLAS SYSTEM ONE 30 boiler is TBC mm high, TBC mm wide, and TBC mm deep.

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

This Ariston CLAS SYSTEM ONE 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 SYSTEM ONE 30 system good for the environment?

With so many of us worried about the environmental impact of our personal choices, the relationship between how we heat our homes and climate change has become an important issue for many homeowners.

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 choosing the Ariston CLAS SYSTEM ONE 30 system help the environment? Let's see what the statistics suggest.

All boilers manufactured and installed in the UK are required to have an energy efficiency rating of 92% or above (or a good “A” SEDBUK rating). Before April 2018, when the law changed, the minimum energy efficiency level permissible was 88% (86-90% is a SEDBUK "B" rating and 90%+ is an "A" rating).

A boiler's energy efficiency rating indicates the amount of energy used and wasted during normal operational performance.

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

What length of warranty does the Ariston CLAS SYSTEM ONE 30 come with?

The Ariston CLAS SYSTEM ONE 30 is covered by a parts and labour warranty of 8 years following installation.
