Ariston CLAS SYSTEM ONE 30 System Gas boiler frequently asked questions

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

The Ariston CLAS SYSTEM ONE 30 is a gas system boiler.

Like heat only boilers, system boilers need a hot water cylinder to work - they're normally installed inside an airing or landing cupboard. However, since system boilers do not require a separate cold water tank, they are popular with homeowners who are planning to convert their loft or where attic space is already at a premium.

They're able to distribute the hot water you need to taps and radiators through (often built-in) circulating pumps and, because there's no water tank to install, they're easier, quicker and cheaper to install than heat only boilers. To get the heat and hot water you need when you need it, just use the control panel to program the times and days you want.

Is the Ariston CLAS SYSTEM ONE 30 system boiler suitable for my house or apartment?

Whether this Ariston CLAS SYSTEM ONE 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 SYSTEM ONE 30 system boiler is 30 kW, so which types of property would this be appropriate for?

Most experienced Gas Safe engineers would likely recommend that, at this level of output, this Ariston CLAS SYSTEM ONE 30 System boiler would be a suitable choice for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


Making space for the Ariston CLAS SYSTEM ONE 30

The measurements of the Ariston CLAS SYSTEM ONE 30 are TBC mm by TBC mm by TBC mm.

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

We recommend the Ariston CLAS SYSTEM ONE 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 SYSTEM ONE 30 system an environmentally friendly boiler?

As the British public has become more conscious of climate change, many homeowners consider the environment when choosing how to heat their homes.

Dangerous levels of nitrogen dioxide emissions in larger UK cities are caused by gas boilers in domestic properties, and 14% of the UK’s greenhouse gas production is as a result of central heating.

Will you be helping the environment if you decide to install a Ariston CLAS SYSTEM ONE 30 system in your home? Let’s look at the figures.

All boilers manufactured after April 2018 in the UK must be rated as an “A” on the SEDBUK grading system, subject to a minimum energy efficiency rating of 92% or above. Before that, the minimum rate was 88% - boilers with an energy efficiency of 88% or 89% were given a “B” rating. Boilers scoring 90% or more were given an "A" rating.

The energy efficiency rating for a boiler describes the amount of energy it uses and how much goes to waste in operation.

The Ariston CLAS SYSTEM ONE 30 has an efficiency rating of 90% with a SEDBUK grade of "A".

If the Ariston CLAS SYSTEM ONE 30 system boiler breaks down, am I covered?

The Ariston CLAS SYSTEM ONE 30 boiler comes with a 8 year warranty for parts and labour.

Ariston CLAS SYSTEM ONE 30 System Gas boiler frequently asked questions

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

If you are searching for a system boiler for your house or flat, the Ariston CLAS SYSTEM ONE 30 is certainly one 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 Ariston CLAS SYSTEM ONE 30 system suitable for my house or flat?

Whether this Ariston CLAS SYSTEM ONE 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.

The output level of a boiler tells you how much power it has to heat the water coming from your taps and warming up your radiators. The higher the output level, the greater the volume of water it can heat up.

If the output (measured in kilowatts) is too high, you'll pay higher gas bills and your water will be piping hot. Too low and the water coming out of your taps and being fed into your radiators will often be lukewarm.

The Ariston CLAS SYSTEM ONE 30 system outputs at a maximum of 30 kW, so which types of property would this Ariston CLAS SYSTEM ONE 30 System boiler be appropriate for?

A Gas Safe boiler installer would recommend that this Ariston CLAS SYSTEM ONE 30 System boiler would be a suitable choice for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


Ariston CLAS SYSTEM ONE 30 dimensions

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 non-condensing or condensing?

The Ariston CLAS SYSTEM ONE 30 is a condensing gas boiler - where possible, we always recommend to clients that they choose one of the very latest condensing boilers to take advantage of this technology, which improves year after year.

Condensing boilers are more energy-efficient as they capture and recycle the heat contained in flue exhaust gases and water vapour condensation. They then use this heat to perform tasks like warming up colder water returning to the boiler from the radiators.

By choosing a condensing boiler, you'll help the environment as well as save money on your gas bills.

Is the system Ariston CLAS SYSTEM ONE 30 boiler energy efficient?

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.

Dangerous levels of nitrogen dioxide emissions in larger UK cities are caused by gas boilers in domestic properties, and 14% of the UK’s greenhouse gas production is as a result of central heating.

Would choosing the Ariston CLAS SYSTEM ONE 30 system boiler be an environmentally friendly decision? Here's what the figures say.

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 Ariston CLAS SYSTEM ONE 30 was awarded an efficiency rating of 90% 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.

What warranty does the Ariston CLAS SYSTEM ONE 30 system boiler come with?

Parts and labour charges incurred for repairs made to your new Ariston CLAS SYSTEM ONE 30 are covered by a 8 year warranty.
