Ariston CLAS ONE R 24 heat only Gas boiler frequently asked questions

Is the Ariston CLAS ONE R 24 a regular, combi or system boiler?

The Ariston CLAS ONE R 24 is a heat only boiler you may wish to consider if you want this particular type of boiler for your house or flat.

Heat only boilers (often referred to as standard boilers, regular boilers or conventional boilers) need both a hot water cylinder and a cold water tank to work. The hot water cylinder heats and keeps warm the water you need and is normally installed in either a utility room or attic. The cold water tank holds water which it passes to the hot water cylinder depending on how you've programmed your boiler.

When you program a heat only boiler, you set the times and days when you want central heating and hot water to be available. However, if you don't remember to program your boiler and there's no water left in the hot water cylinder, you may have to wait up to an hour for hot water to come out of your taps.

Heat only boilers can cope with the demand for hot water from multiple taps and sources around your home simultaneously. That's why they're better for larger homes than combi boilers - combi boilers struggle when more than one hot tap is turned on. This is because they have a maximum capacity of water they can heat and distribute at any one time, meaning water pressure, temperature and volume to each tap drops.

Is the Ariston CLAS ONE R 24 heat only boiler suitable for my house or apartment?

Whether this Ariston CLAS ONE R 24 heat only 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 ONE R 24 heat only is 21 kW, so which types of property would this model be appropriate for?

Most experienced Gas Safe boiler installers would recommend that a boiler with this output level would be most suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


How big is the Ariston CLAS ONE R 24?

The Ariston CLAS ONE R 24 is TBC mm tall, TBC mm wide, and TBC mm deep in size.

Ariston CLAS ONE R 24 – condensing or non-condensing?

Is the Ariston CLAS ONE R 24 heat only boiler environmentally friendly?

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.

As much as 14% of the UK’s greenhouse gas production derives from our domestic central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in Britain's largest cities.

Do the available figures suggest that installing the Ariston CLAS ONE R 24 heat only in your property would be an environmentally friendly choice?

Boilers manufactured after April 2018 in the UK must achieve an "A" on the SEDBUK grading system as well as score a minimum of 92% on a separate energy efficiency test. Prior to that, the minimum was 88% - boilers rated at 88% and 89% were given a “B” rating (90% and higher were given an "A").

An energy efficiency rating describes how much energy the boiler uses and how much it wastes when in use.

The Ariston CLAS ONE R 24 was awarded an efficiency rating of 94% with a SEDBUK grading of "A".

In 2015, the Energy Related Products Directive (ERP) came into force. The legislation applies to all products that consume energy - in production, during their active life, and at the point of final disposal.

The ERP was introduced to incentivise manufacturers to create products that emit fewer harmful gases with the larger aim of protecting the wider environment.

The Ariston CLAS ONE R 24 has been awarded an ERP rating of "A".

If the Ariston CLAS ONE R 24 breaks down, will I be covered by the warranty?

Ariston’s CLAS ONE R 24 boiler includes a parts and labour warranty of 8 years.

Ariston CLAS ONE R 24 heat only Gas boiler frequently asked questions

Is the Ariston CLAS ONE R 24 boiler a standard, combi or system model?

If you are considering installing a heat only boiler in your house or flat, then the Ariston CLAS ONE R 24 boiler is certainly worth investigating.

You may hear a heat only boiler being called a regular boiler, a conventional boiler or a standard boiler. With a regular boiler, you need to find room within your property for a hot water cylinder with an immersion heater (usually in a landing cupboard or airing cupboard) and a cold-water tank (usually in the loft). The immersion cylinder is what keeps your hot water warm all day.

With a regular boiler, you schedule your hot water and heating for set times during the day or week, but if you forget to do so and the hot water runs out, you'll need to wait for your boiler to heat enough water before you can have a bath or shower - that can sometimes take up to an hour.

A regular boiler is suitable for homes with more than one bathroom or larger families when there is high demand for hot water. Although combi boilers are the most popular type of boiler in Britain, water pressure, volume and temperature drop if there is simultaneous demand from two or more points - for example, someone running a hot water tap when someone else is in the shower.

Is a Ariston CLAS ONE R 24 heat only the right boiler for my house or flat?

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

The amount of hot water you get from showers, bathrooms, and sinks and heat from your radiators depends on your boiler's output (measured in kilowatts). The higher the level of output, the better your home will be heated and you can be more certain that the water from your taps will be as hot as you want.

However, you must be careful. You might not get the hot water you want if your boiler output is too low. If it's too high, you'll be paying more than you need to for gas.

With the Ariston CLAS ONE R 24 heat only's output at 21 kW, which types of property would this Ariston CLAS ONE R 24 heat only boiler be most appropriate for?

A PlumbProud heating engineer would likely recommend that this Ariston CLAS ONE R 24 heat only boiler is suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


Dimensions of the Ariston CLAS ONE R 24 boiler

The dimensions of the Ariston CLAS ONE R 24 are TBC mm tall, TBC mm wide, and TBC mm deep.

Is the Ariston CLAS ONE R 24 condensing or non-condensing?

Is the Ariston CLAS ONE R 24 heat only considered environmentally friendly?

Environmentally-friendly heating has become an important issue for homeowners concerned about the accelerating pace of 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.

Would choosing the Ariston CLAS ONE R 24 heat only help the environment? Let's see what the statistics suggest.

Boilers manufactured in the UK must be tested and, by law, achieve an energy efficiency rating of 92% or above, equivalent to a SEDBUK "A" grade. Most boilers achieve an "A" rating meaning they are at least 88% efficient.

The energy efficiency of a boiler indicates the amount of energy it uses (and wastes) during operation.

The Ariston CLAS ONE R 24 has been assigned an efficiency rating of 94% with a SEDBUK rating of "A".

The Energy Related Products Directive (ERP) intends to reduce the amount of energy consumed by individual products over their entire lifetime, from the initial manufacturing process to final disposal and at all points in between.

The legislation is designed to encourage manufacturers to create products that are more environmentally friendly and which result in a reduction in harmful gas emissions.

The ERP rating for the Ariston CLAS ONE R 24 is "A".

Am I covered if my Ariston CLAS ONE R 24 heat only boiler breaks down?

The Ariston CLAS ONE R 24 boiler comes with a parts and labour warranty lasting 8 years.
