Atag iS 18 System Gas boiler frequently asked questions

Is the Atag IS 18 a standard, combi or system boiler?

The Atag IS 18 boiler is a system boiler you may wish to consider when looking for a new boiler for your house or flat.

System boilers share many similarities with more traditional heat only boilers, like the need to program the times you want them to provide you with heat and hot water - just use the control panel to do this.

Where they differ from regular boilers is that they do not require a separate cold-water tank - everything is done within the hot water cylinder, which contains built-in circulating pumps. This makes them easier to install as there is one less component to fit and makes them more suitable for properties with no loft space, smaller lofts or for homeowners who are considering converting their loft.

As long as you have programmed your system boiler in advance, you will have the hot water you need ready for whenever you want to use it. Once the water is heated, it will remain available, warm, inside the tank until it’s all used up. It will then draw more water from the mains to start heating so that it can provide heat and hot water for the times you've told the system boiler you need it.

Would the Atag IS 18 system be a suitable boiler for my house or flat?

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.

Your boiler's output indicates the maximum amount of power available to it to heat the water you need to warm your radiators or when you want hot water from your taps. A higher output rate means that your boiler is capable of heating greater volumes of water.

If a boiler's output rate is too low, you'll often find that the water is not as hot as you want it to be. Too high, however, and you'll end up paying more for your gas than you should be.

The Atag IS 18 system boiler has an output rate of 17 kW, so which types of property would this be suitable for?

A heating engineer would recommend that the Atag IS 18 system boiler would be a suitable installation option for smaller homes and apartments with up to 10 radiators and one bathroom.


How big is the Atag IS 18?

The dimensions of the Atag IS 18 are TBC mm [H] x TBC mm [W] x TBC mm [D].

Atag IS 18 – condensing or non-condensing?

The Atag IS 18 is a condensing gas boiler - we strongly recommend that you choose one of the latest condensing models if possible.

With a condensing boiler, you save money on your gas bills because your boiler captures and recycles the heat present in the flue exhaust gases and water vapour condensation for re-use, meaning they operate far more economically and efficiently.

Does the Atag IS 18 system protect the environment?

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.

In the UK, central heating is responsible for 14% of greenhouse gas production. Domestic gas boilers emit large quantities of nitrogen dioxide in British cities.

If you would like your next boiler to help in the fight against climate change, would the Atag IS 18 system be a suitable choice?

All boilers manufactured and installed in the UK are required to have an energy efficiency rating of 92% or above (or a good “A” SEDBUK rating). Before April 2018, when the law changed, the minimum energy efficiency level permissible was 88% (86-90% is a SEDBUK "B" rating and 90%+ is an "A" rating).

A boiler's energy efficiency rating indicates the amount of energy used and wasted during normal operational performance.

Following its assessment, the Atag IS 18 was given an efficiency rating of 93% and a SEDBUK grading of "A".

The Energy Related Products (ERP) Directive's aim is to reduce the harmful gas emissions created during a product’s manufacture and active end use right through to its disposal.

The ERP rating for the Atag IS 18 is "TBC".

What warranty do I get if I purchase the Atag IS 18 boiler?

On the Atag IS 18, the manufacturer offers a parts and labour warranty of 14 years.

Atag iS 18 System Gas boiler frequently asked questions

What type of boiler is Atag’s IS 18 - system, regular or combi?

If you want a system boiler for your flat or house, the Atag IS 18 might be an option for you to consider.

System boilers need a hot water cylinder to work but, unlike heat only boilers, they don't require a cold water tank. This can be advantageous if you live in an apartment, lack attic space, or are planning a loft conversion.

System boilers allow you to set the times when you want hot water to be available. Heated water is stored in the cylinder and can be used throughout the day. With a system boiler, if you forget to set the timer, you will have to wait a while for hot water.

The constant supply of hot water from the cylinder ensures that you can have multiple taps and showers in use without a loss of pressure to each point (something combi boilers struggle with). This makes a system boiler suitable for large families and homes with more than one bathroom.

Is a Atag IS 18 system boiler suitable for my house or flat?

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

A boiler's output level measures how much power it can use to provide you with the hot water you need for your radiators and taps. If a boiler has a high output rate, it can heat greater volumes of water.

If you choose a boiler with too low an output, you'll find that the water coming out of your taps and in your radiators won't be as hot as you want it to be. Choosing one whose output is too high means you'll pay more than you need to for the gas your boiler needs to work.

The Atag IS 18 system outputs at a maximum of 17 kW, so which types of property would this Atag iS 18 System boiler be appropriate for?

An experienced boiler engineer would recommend that this Atag iS 18 System boiler would be a suitable installation choice for smaller homes and apartments with up to 10 radiators and one bathroom.


Atag IS 18 - size in millimetres

The dimensions of the Atag IS 18 are TBC mm tall, TBC mm wide, and TBC mm deep.

Atag IS 18 – condensing or non-condensing?

We recommend the Atag IS 18 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 Atag IS 18 system an environmentally friendly boiler?

How we heat our homes has become a major issue for many people worried about climate change and environmental issues in general.

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.

Is the Atag IS 18 system an environmentally friendly choice for your home? Let’s have a look at the figures.

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 Atag IS 18 has been assigned an efficiency rating of 93% with a SEDBUK rating of "A".

The ERP (or Energy Related Products Directive) is European legislation which applies to all products that consume energy throughout their lifetime.

Its purpose is to encourage manufacturers to offer products that are kinder to the environment by reducing harmful gas emissions at all stages, from production and end use right through to disposal.

The ERP rating for the Atag IS 18 is "A".

What length of warranty does the Atag IS 18 come with?

The Atag IS 18 boiler offers a parts and labour warranty of 14 years.
