Atag iC 24 Combi Gas boiler frequently asked questions

What type of boiler is Atag’s IC 24 - system, regular or combi?

If you’re looking for a combi boiler for your house or flat, then the Atag IC 24 is one you may wish to consider.

Traditionally, boilers needed one or more large tanks installed in your property to store their heated water or water that was to be heated later. These tanks were often too large to be practical for most homes so the combi boiler was introduced to Britain in the 1970s by manufacturers to help homeowners overcome this issue.

Instead of using tanks as storage, a combi boiler heats water on demand. It draws water from the mains and heats it instantly on demand before distributing it to wherever it is needed in a property, be it your taps or radiators.

Unfortunately, combi boilers have one main disadvantage for larger properties or larger households. Because they have a maximum volume of water that can be heated on demand at any given time, water pressure, volume and temperature will drop if, for example, someone is taking a shower and another person in your home wants to use a hot water tap at the same time.

Is the Atag IC 24 combi boiler from the IC range a suitable choice for my house or flat?

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 Atag iC 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 Atag IC 24 combi boiler has an output level of 23 kW, so which types of property would it be appropriate for?

To most experienced Gas Safe engineers, the Atag IC 24 combi IC would be most suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

The Atag IC 24 is a combi boiler, which that means that you need to take the flow rate (measured in litres per minute) into account as well as the output rate. This Atag iC 24 Combi boiler's flow rate is 10 L/m.

Combis draw water from the mains, instantly heating and distributing it where it's needed - taps, radiators, bathrooms, and so on.

However, this means that the flow rate of a boiler may effectively be capped by the flow rate of the mains water supply. For example, if your mains pressure is 12l/m, that is the maximum flow rate that your boiler can achieve even if you choose a boiler with a flow rate of 18l/m.

In addition, if your home has more than one bathroom, a high number of radiators, and more than one member of your household wants to use hot water at the same time regularly, the flow rate of both the boiler and the mains water pressure may not be high enough.

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.


How large is the Atag IC 24?

The Atag IC 24 is TBC mm [H] by TBC mm [W] by TBC mm [D] in size.

IC 24 – condensing or non-condensing?

Condensing boilers like the Atag IC 24 improve energy efficiency and reduce your annual expenditure on gas.

They do this by capturing and recycling the warmth still present in water vapour condensation and flue exhaust gases to, for example, increase the temperature of the colder water returning from your radiators.

Condensing boilers are also much better for the environment because they emit fewer greenhouse gases.

Does the Atag IC 24 combi protect the environment?

More and more homeowners are aware of the importance of how we heat our homes and its impact on climate change and other environmental issues.

The heating of our homes accounts for 14% of the UK's greenhouse gas emissions. Especially in the big cities, gas boilers are responsible for dangerous levels of nitrogen dioxide emissions.

If you would like your next boiler to help in the fight against climate change, would the Atag IC 24 combi be a suitable choice?

By law, boilers manufactured and supplied in the UK must achieve a SEDBUK rating of "A" and work at a 92% minimum efficiency. Before April 2018, a minimum of 88% energy efficiency needed to be achieved (88/89% = SEDBUK "B" and 90% = SEDBUK "A").

Following official testing, the Atag IC 24 was given an efficiency rating of 94% with a SEDBUK rating of "A".

Energy efficiency is a measure of how much energy is used and how much is wasted when a boiler is operating.

The ERP (Energy Related Products Directive) applies to all products that consume energy at any time in their lifetime, from manufacture to disposal and all points in between.

This European legislation intends to encourage manufacturers to offer end users products that are better for the environment through the creation of fewer harmful gas emissions at all points of a product's life cycle.

The ERP rating for the Atag IC 24 is "A" for heat and "A" for water.

What warranty does the Atag IC 24 combi boiler come with?

Parts and labour charges incurred for repairs made to your new Atag IC 24 are covered by a 14 year warranty.

Atag iC 24 Combi Gas boiler frequently asked questions

Is the Atag IC 24 boiler a combi, regular or a system boiler?

The Atag IC 24 is worthy of consideration if you're looking for a combi boiler for your flat or house.

The UK has some of the smallest homes in the Western world, which is partly why combi boilers were introduced in the 1970s. Traditional boilers require one or more large storage tanks which they use to either heat water and keep it warm or store water intended for heating later. These tanks took up a lot of space in people's homes.

Combi boilers save space because they don't require these tanks to operate. Instead, combis draw water direct from your mains supply then instantly heat and distribute it on demand.

The biggest disadvantage in using combi boilers is that they have a maximum capacity volume for heating water. While this may not be an issue in a small household, it could be for a larger household where there is higher demand for hot water. When more than one person is using the water, it is distributed between the two points, reducing the pressure and temperature at each point.

Is a Atag IC 24 combi boiler appropriate for my house or apartment?

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

Boiler output is measured in kilowatts and tells you how much power a boiler can use to heat the water your taps, showers and radiators need. The higher the output, the more power it has.

When choosing a boiler, you should choose one that can cope with the peak demand for hot water in your home and not just your typical usage.

If its output is too low, sometimes your hot water will not be hot enough, but if your boiler's output is too high for your needs, your gas bills will go up and not down.

The output of the Atag IC 24 combi is 23 kW, so which types of property would this Atag iC 24 Combi boiler be an appropriate choice for?

A PlumbProud Gas Safe engineer would recommend that the most suitable type of property for a Atag IC 24 combi would be smaller homes and apartments containing up to 10 radiators and providing hot water for one bathroom.

You also need to choose a combi boiler with the right flow rate for where you live.

A combi boiler's flow rate is the maximum volume of water (measured in litres per minute) that it can heat and distribute to your radiators, taps and showers at the same time. This Atag iC 24 Combi boiler's flow rate is 10 L/m.

However, combi boilers like the Atag IC 24 draw water directly from the mains and heat it instantly.

If your mains pressure is 12 litres per minute, your boiler can only heat and distribute hot water at a rate of 12 litres per minute even if it has a higher flow rate.

Combi boilers also struggle when multiple people in your home want to use hot water at the same time - for example, someone running the hot water tap in the kitchen and two people wanting to shower in separate bathrooms.

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.


Dimensions of the Atag IC 24 boiler

The dimensions of the Atag IC 24 are TBC mm tall, TBC mm wide, and TBC mm deep.

Is the Atag IC 24 condensing or non-condensing?

We strongly recommend that you choose a condensing boiler like the Atag IC 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 Atag IC 24 combi good for the environment?

How we heat our homes and the effect that has on climate change has become important to many homeowners worried about the environment.

Approximately 14% of the UK's greenhouse gas production is caused by our central heating systems. The gas boilers in larger urban areas of Britain are mainly responsible for emissions of toxic nitrogen dioxide.

If you would like your next boiler to help in the fight against climate change, would the Atag IC 24 combi be a suitable choice?

All boilers manufactured and supplied in the UK must achieve an energy efficiency rating of at least 92% (an "A" SEDBUK grade). This is higher than the previous 88%, which was a legal requirement prior to April 2018.

The energy efficiency rating is used to work out how much energy a boiler both uses and wastes when it's switched on and working correctly - its standard functioning and operation.

The Atag IC 24 is rated as 94% energy efficient, equivalent to a "A" SEDBUK rating.

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 Atag IC 24 is rated "A" for heat and "A" for water.

What is the length of the warranty on the Atag IC 24?

The Atag IC 24 boiler comes with a parts and labour warranty lasting 14 years.
