Ariston E-COMBI ONE 24 Combi Gas boiler frequently asked questions

Is this Ariston E-COMBI ONE 24 boiler a combi, system or regular boiler?

The Ariston E-COMBI ONE 24 boiler is a combi boiler you may wish to consider when looking for a new boiler for your house or flat.

Traditional boilers would require you to install one or more storage tanks in your property. These tanks either kept the water warm or stored it for later heating. Manufacturers initially designed and introduced combi boilers to the market to offer homeowners the highest levels of warmth and unlimited hot water without taking up as much space.

Combi boilers provide hot water on demand for your radiators and taps. They take water directly from the mains, heat it immediately as it's needed, and then distribute the hot water around your home.

Combi boilers, however, are limited in terms of how much water they can heat at any given time. For example, if one person wishes to take a shower while another wants to turn on a hot water tap, the amount of water reaching each point drops. This results in a drop in the water pressure as well as the temperature.

Is a Ariston E-COMBI ONE 24 combi boiler suitable for my house or apartment?

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

This Ariston E-COMBI ONE 24 Combi boiler gets its power from gas and the power it's capable of producing is measured in kilowatts - the output rate is actually a kilowatt rate. The higher the output rate, the more kilowatts a boiler can use when heating water.

If you choose a boiler whose output rate is too low, it may not have enough power to make your water as hot as you would like. If you choose a boiler whose output rate is too high, you won't have to put up with lukewarm water but you will face higher gas bills.

The Ariston E-COMBI ONE 24 combi boiler has an output level of 22 kW, so which types of property would it be appropriate for?

An experienced PlumbProud Gas Safe engineer would almost certainly recommend that this Ariston E-COMBI ONE 24 Combi boiler would be most suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

With combi boilers like the Ariston E-COMBI ONE 24, you need to take the flow rate into account as well as the output rate.

Combi boilers draw water from the mains and then instantly heat that water and send it to wherever in your home it's needed. Flow rates, measured in litres per minute, are subject to the mains water pressure in your area. So, for example, if the local mains water pressure is 11 litres per minute and the flow rate of your boiler is 14 litres per minute, the boiler will not be able to process more than 11 litres per minute. The flow rate of this Ariston E-COMBI ONE 24 Combi boiler is 12 L/m.

If you live in a home with lots of radiators or bathrooms where many people want to use hot water at the same time, a combi boiler may not be able to cope. For reference, a power shower uses about 10 litres of water per minute. If two people want showers at the same time or one person wants a shower and the other hot water from a tap in the kitchen, your boiler may not have a large enough flow rate even if the local mains water pressure is high.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


The size of the Ariston E-COMBI ONE 24 in millimetres

The Ariston E-COMBI ONE 24 measures TBC mm high and TBC mm wide by a depth of TBC mm.

Is the Ariston E-COMBI ONE 24 a condensing or non-condensing boiler?

The Ariston E-COMBI ONE 24 is a condensing boiler – we recommend to all clients that they choose the very latest condensing boilers because their efficiency continues to improve year after year.

Condensing boilers recycle heat from both water vapour condensation and flue exhaust gases via a secondary heat exchanger. With this heat, it performs other tasks like warming up colder water returning from your radiator without having to use more gas.

You will save money on your gas bills every year by choosing a condensing boiler as well as benefitting the environment.

Is the Ariston E-COMBI ONE 24 combi boiler rated as environmentally friendly?

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

In the largest cities of Britain, gas boilers are responsible for dangerous levels of atmospheric nitrogen dioxide emissions. In total, 14% of the UK’s greenhouse gases are produced by central heating systems.

Will you be helping the environment if you decide to install a Ariston E-COMBI ONE 24 combi in your home? Let’s look at the figures.

By law, the minimum level of energy efficiency for boilers manufactured in the UK is 92%, equivalent to a good SEDBUK “A” rating. Prior to April 2018, the minimum was 88% - boilers whose energy efficiency levels were 88% or 89% were given a "B" rating on the SEDBUK scale and those at 90% or higher were given an "A".

The energy efficiency rating awarded to each boiler indicates the amount of energy that is wasted when in operation.

Following testing, the Ariston E-COMBI ONE 24 was given a 94% energy efficiency rating and a SEDBUK grading of "A".

The ERP (Energy Related Products Directive) is European legislation that aims to reduce the use of energy at all points during a product's life, from the point of manufacture to when it's in active use right through to final disposal.

The regulation aims is to encourage manufacturers to create products that are more environmentally friendly and which reduce the harmful gas emissions associated with those products.

The ERP gradings for the Ariston E-COMBI ONE 24 are "A" for heat and "A" for hot water.

Will I be covered if the Ariston E-COMBI ONE 24 combi breaks down?

The Ariston E-COMBI ONE 24 boiler is provided with a parts and labour warranty lasting 2 years.

Ariston E-COMBI ONE 24 Combi Gas boiler frequently asked questions

Is the Ariston E-COMBI ONE 24 a system, regular or combi boiler?

The Ariston E-COMBI ONE 24 boiler is a combi boiler you may wish to consider when looking for a new boiler for your house or flat.

In older British homes, traditional boilers required you to find room for one or more storage tanks. One tank would keep hot water warm and the other stored cold water for later heating. Manufacturers introduced combi boilers to the UK in the 1970s so that homeowners could get the warmth and hot water they needed without having to sacrifice too much valuable space – remember that residential property in this country is among the smallest in the Western world.

Combi boilers deliver hot water to your radiators and taps using water they draw directly from the mains supply. As mains water travels through a combi boiler, the technology within it heats the cold water instantly and on demand. The hot water is then distributed throughout your house.

Combi boilers have one drawback, however: they can only heat a certain amount of water within a given time. For example, if someone uses the shower and another person uses the hot water tap at the same time, water pressure drops because water reaches each point differently.

Should I choose a Ariston E-COMBI ONE 24 combi boiler for my house or flat?

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

A boiler’s output indicates the amount of power it can use when heating the water which it then sends to your taps and radiators. The higher the output rate, the more water it can heat.

If a boiler’s output is too low, there will be times when your hot water might not be as hot as you want it to be. If it is too high, you’ll likely be paying more than you need to for your gas.

Measured in kilowatts, the Ariston E-COMBI ONE 24 combi's output level is 22 kW, so which types of property would this Ariston E-COMBI ONE 24 Combi boiler be an appropriate choice for?

An experienced PlumbProud heating engineer would recommend that the level of output from this Ariston E-COMBI ONE 24 Combi boiler would make it a suitable installation option for smaller homes and apartments with up to 10 radiators and one bathroom.

With all combi boilers, you need to consider the "flow rate" as well as the output rate when making your decision.

Like all combi boilers, the Ariston E-COMBI ONE 24 draws water from the mains. It instantly heats that water and then distributes it to the parts of your home which need it - taps, radiators, bathrooms, and so on. This Ariston E-COMBI ONE 24 Combi boiler's flow rate is 12 L/m.

There is no benefit to purchasing a boiler with a high flow rate if the local water pressure is not that good - a high flow rate doesn't mean that your combi can draw more water from the mains.

In addition, if you live in a home with a large number of radiators and more than one bathroom and if more than one person regularly wants to use hot water at a time, a combi boiler may struggle to provide enough water at a hot enough temperature.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


What are the dimensions of the Ariston E-COMBI ONE 24 boiler?

The Ariston E-COMBI ONE 24 measures TBC mm tall, TBC mm wide, and TBC mm deep.

Is the Ariston E-COMBI ONE 24 condensing or non-condensing?

We strongly recommend that you choose a condensing boiler like the Ariston E-COMBI ONE 24 - 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.

Is the Ariston E-COMBI ONE 24 combi an energy-efficient boiler?

As more of us become concerned by the effects of climate change, the damage we do to the environment by heating our homes has emerged as an important issue for many homeowners.

Nitrogen dioxide emissions in Britain's largest cities are at dangerous levels and this has been caused by gas boilers. In fact, 14% of the UK’s greenhouse gases are produced by central heating.

Would choosing the Ariston E-COMBI ONE 24 combi be an environmentally-friendly choice? If so, let's look at its performance figures.

All boilers manufactured and installed in the UK are required by law to have an energy efficiency rating of at least 92%, equivalent to a good “A” rating on the SEDBUK scale. Before this, the minimum was 88% (ratings of 88% and 89% are equivalent to a high “B” SEDBUK rating and anything 90% or higher is an "A" rating).

A boiler's energy efficiency rating is designed to let you know how much energy is used and wasted during normal functioning.

The Ariston E-COMBI ONE 24 was given an efficiency rating of 94% and a band rating of "A".

The Energy Related Products (ERP) Directive is a European directive which applies to all products that consume energy over their lifetime.

It encourages companies to create products that are environmentally friendlier at all life cycle stages, including initial manufacturing and end use through to final disposal, with the aim of reducing harmful gas emissions.

The Ariston E-COMBI ONE 24 is rated "A" for heat and "A" for water.

Does a Ariston E-COMBI ONE 24 combi boiler come with a warranty period?

A parts and labour warranty of 2 years is included when you purchase the Ariston E-COMBI ONE 24 boiler through PlumbProud.
