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

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

You might want to consider the Ariston CLAS ONE R 24 for your house or flat if you are looking for a heat only boiler.

Heat only boilers are sometimes called standard boilers, regular boilers or conventional boilers but they are actually the same thing. For a heat only boiler, you'll need to find space for both a cold-water tank and an immersion hot water cylinder - most households choose the attic for the former and a landing cupboard or airing cupboard for the latter. The immersion cylinder is the part of the system that keeps your hot water warm.

You program your boiler to provide you with the hot water you want at certain times, such as when you want to have a bath or a shower. However, if you don't remember to program your boiler, you'll have to wait for it to heat up if the hot water has run out.

A regular boiler is the most suitable choice if you have a larger family or if there is more than one bathroom in your home - the more popular combi boilers do not work well in homes where there is high and often simultaneous demand for hot water.

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

To determine that, we need to consider the size of the boiler. However, size doesn't refer to how big a boiler is - it means the size of its "output".

Your boiler’s output is a measurement of the power it has available to heat the volume of water required for your taps and radiators. The higher the output rate, the more water it can heat.

You need to be careful to select a boiler with the optimal level of output for your property though. That's because, if your boiler output is too low, your water and radiators will often not be as hot as you want them to be. If the output is too high, you’ll be paying more for gas than you need to.

The output of the Ariston CLAS ONE R 24 heat only is 21 kW, so which types of property would this Ariston CLAS ONE R 24 heat only boiler be appropriate for?

An experienced PlumbProud Gas Safe boiler installer would recommend that this Ariston CLAS ONE R 24 heat only boiler is appropriate for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

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

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

The effects of climate change on the environment are leading many homeowners to question the damage they might be doing by the way they heat their homes.

Central heating accounts for 14% of greenhouse gas emissions in the UK. In larger British cities, gas boilers emit dangerous levels of nitrogen dioxide into the atmosphere.

Let's take a closer look at whether installing a Ariston CLAS ONE R 24 heat only would be a good choice for the environment.

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 ONE R 24 scored an efficiency rating of 94% and a SEDBUK band rating of A.

The Energy Related Products (ERP) Directive is important European legislation that aims to limit energy use and harmful gas emissions during the manufacturing process, when the product is in use, and after it is disposed of.

For the Ariston CLAS ONE R 24, the ERP Heat rating is "A".

If the Ariston CLAS ONE R 24 heat only boiler breaks down, am I covered?

Parts and labour charges incurred for repairs made to your new Ariston CLAS ONE R 24 are covered by a 8 year warranty.

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

Which category of boiler does the Ariston CLAS ONE R 24 fit into?

If you are searching for a heat only boiler for your house or flat, the Ariston CLAS ONE R 24 is certainly one to consider.

If your home has more than one bathroom or you have a large family that uses a lot of hot water, a heat only boiler (sometimes called a regular boiler, a conventional boiler or a standard boiler) is likely to be the best option for you. Heat only boilers require both a hot water or immersion cylinder and a cold water tank. Once the water in the cylinder is heated, you can use this hot water throughout the day and it can feed multiple taps and showers at the same time.

This is in contrast to a combi boiler which can only heat a limited amount of water at any one time. This can cause a problem if two or more taps and showers are being used simultaneously as the temperature, pressure and volume to all points will drop.

Heat only boilers allow you to program the times that you wish heat and hot water to be available. However, if you forget to do this and the immersion cylinder is empty, you may have to wait up to an hour before hot water becomes available again.

If your property already has a water tank and cylinder, it will nearly always be cheaper to replace like for like and not choose a different type of boiler. In addition to new pipework, you may need to replace older radiators that may be unable to cope with the higher water pressure delivered by other types of boiler.

Should I install a Ariston CLAS ONE R 24 heat only boiler in my house or flat?

You should make sure that the boiler you install in your property is the right "size". And size doesn't mean its physical dimensions, size means how much power it has - the "output".

Output measures in kilowatts how much power a boiler can use when heating water for your radiators or taps. The higher the output rate, the more water it can heat.

If the output rate is too low, your hot water might often be only lukewarm, and if it is too high, you will be paying more for your gas than you need to.

The Ariston CLAS ONE R 24 heat only boiler has an output of 21 kW, so which types of property would it be most appropriate for?

A boiler engineer would be likely to recommend that this Ariston CLAS ONE R 24 heat only boiler is capable of providing heating and hot water to 10-15 radiators and two bathrooms and would therefore be most suitable for medium-sized homes and larger apartments.


Ariston CLAS ONE R 24 dimensions

The Ariston CLAS ONE R 24's dimensions are TBC mm [H] x TBC mm [W] x TBC mm [D].

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

Is the heat only Ariston CLAS ONE R 24 boiler energy efficient?

How we heat our homes and the damage this does to the environment has become a pressing concern for many homeowners worried about the effects and impact of climate change.

In Britain's bigger cities, gas boilers, in particular, are responsible for dangerous levels of nitrogen dioxide emissions. Overall, 14% of all of the UK’s greenhouse gas production comes from heating our homes.

Would choosing the Ariston CLAS ONE R 24 heat only boiler be an environmentally friendly decision? Here's what the figures say.

All boilers manufactured and supplied in the UK are assigned two energy efficiency ratings. By law, they must achieve a SEDBUK "A" rating subject to a minimum efficiency level of 92%. Prior to that, the minimum was 88% (88% and 89% are equivalent to a SEDBUK "B" grade and 90% and above an "A" grade).

The ratings awarded to the Ariston CLAS ONE R 24 are 94% with a SEDBUK rating of "A".

Energy-efficient boilers help the environment as they require less fuel and emit fewer harmful gases. In 2015, the EU introduced the Energy Related Products Directive (ERP) with the aim of ensuring that all manufacturers, including boiler manufacturers, developed more efficient products and processes.

This legislation aims to conserve energy at all life cycle stages, from initial production through to actual use by a customer and up to the point of disposal.

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

If the Ariston CLAS ONE R 24 heat only boiler breaks down, am I covered?

On the Ariston CLAS ONE R 24, the manufacturer offers a parts and labour warranty of 8 years.
