Atag iS 18 System Gas boiler frequently asked questions

What type of boiler is the Atag IS 18?

Suitable for a house or a flat, the Atag IS 18 system boiler is worth considering if you want a system boiler.

System boilers, like regular boilers, require a hot water cylinder (usually placed in a landing or airing cupboard) to work but they don’t require a separate cold water tank. This makes installation quicker and easier and, for homeowners with little loft space or who are considering a loft conversion, they're a more suitable choice.

System boilers don't need separate water tanks because they contain built-in circulating pumps that perform the same task. Just like heat only boilers, they require you to program in the times when you want heating and hot water to be available - they don't offer instant hot water like combi boilers. The cylinders keep whatever water they contain warm, although, if there is no hot water in the tank, you will have to wait up to an hour before hot water will come through your taps.

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

Whether this Atag iS 18 System boiler is right for where you live depends on its size or "output" level. Size does not mean its physical dimensions - it means how powerful it is.

The output level of a boiler tells you how much power it has to heat the water coming from your taps and warming up your radiators. The higher the output level, the greater the volume of water it can heat up.

If the output (measured in kilowatts) is too high, you'll pay higher gas bills and your water will be piping hot. Too low and the water coming out of your taps and being fed into your radiators will often be lukewarm.

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 Gas Safe engineer would be likely to recommend that this Atag iS 18 System boiler is capable of providing heating and hot water to up to 10 radiators and one bathroom and would therefore be most suitable for smaller homes and apartments.


What are the proportions of a Atag IS 18 boiler?

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

Is the Atag IS 18 a condensing or non-condensing boiler?

Because of their increased energy efficiency, we recommend to all customers that they select one of the latest condensing boilers. Condensing boilers capture the heat from water vapour condensation and flue exhaust gases and recycle that heat to warm water entering the boiler (for example, from your radiators).

The Atag IS 18 is a condensing gas boiler and choosing this model will result in a likely substantial reduction in your fuel bills, particularly if you're replacing an older, inefficient, non-condensing boiler.

Is the system Atag IS 18 boiler energy efficient?

Many homeowners are becoming increasingly concerned about how they heat their homes and the impact it has on climate change and other important environmental issues.

Gas boilers are responsible for dangerous atmospheric levels of nitrogen dioxide emissions in Britain's biggest cities and, overall, 14% of the UK’s greenhouse gases are produced by our domestic central heating systems.

Will choosing to install a Atag IS 18 system in your home help the environment? Let's review the figures.

An energy efficiency rating of 92% or above is a legal requirement for all boilers manufactured and installed in the UK today. 92% is equivalent to a low-to-middle "A" grade on the "Seasonal Efficiency of Domestic Boilers" (SEDBUK) scale.

Energy efficiency measures how much energy a boiler uses and wastes in the course of its normal operation. The lower the waste, the lower your gas bills.

The Atag IS 18 was awarded an efficiency rating of "93%", equivalent to a "A" rating on the SEDBUK system.

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 right through to final disposal, with the aim of reducing harmful gas emissions.

The Atag IS 18 is rated "A".

Will I be covered if the Atag IS 18 system breaks down?

Parts and labour charges incurred for repairs made to your new Atag IS 18 are covered by a 14 year warranty.

Atag iS 18 System Gas boiler frequently asked questions

What kind of boiler is the Atag IS 18 - standard, combi or system?

You might want to consider the Atag IS 18 for your house or flat if you are looking for a system boiler.

System boilers, like regular boilers, require a hot water cylinder (usually placed in a landing or airing cupboard) to work but they don’t require a separate cold water tank. This makes installation quicker and easier and, for homeowners with little loft space or who are considering a loft conversion, they're a more suitable choice.

System boilers don't need separate water tanks because they contain built-in circulating pumps that perform the same task. Just like heat only boilers, they require you to program in the times when you want heating and hot water to be available - they don't offer instant hot water like combi boilers. The cylinders keep whatever water they contain warm, although, if there is no hot water in the tank, you will have to wait up to an hour before hot water will come through your taps.

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

Selecting the right boiler for your property means selecting a boiler that is the right "size". And, by size, we don't mean how big it is, we mean how powerful it is - its "output".

The output rate tells you how much energy your boiler has to use to provide you and your family with hot water and central heating. A higher output rate means that it can heat greater volumes of water.

Please be aware, though - if you choose a boiler whose output is too low, the water in your radiators and coming from your taps may not be warm enough. Conversely, if you choose a boiler with too high an output, you'll pay more for gas than is necessary.

The Atag IS 18 system boiler has an output level of 17 kW, so which types of property would it be appropriate for?

A Gas Safe engineer would recommend that the Atag IS 18 system boiler is a suitable choice for smaller homes and apartments with up to 10 radiators and one bathroom.


How large is a Atag IS 18 boiler?

The Atag IS 18 is TBC mm tall, TBC mm wide, and TBC mm deep in size.

Is the Atag IS 18 a non-condensing or condensing boiler?

We recommend that, if possible, you choose a condensing boiler like the Atag IS 18.

Condensing boilers are more energy-efficient. They achieve this efficiency by capturing the heat present in flue exhaust gases and water vapour condensation and recycling that heat to, for example, warm colder water coming back from your radiators.

By choosing the latest condensing boiler, you'll also notice a significant reduction in your gas bills, particularly if you're replacing a boiler more than 15 years old.

Is the Atag IS 18 system an energy-efficient boiler?

Many homeowners are becoming increasingly concerned about how they heat their homes and the impact it has on climate change and other important environmental issues.

In the UK, central heating systems account for 14% of greenhouse gas production. Gas boilers in particular are responsible for emissions of dangerous nitrogen dioxide in British cities.

Is the Atag IS 18 system boiler an environmentally friendly choice for your home? Here’s what the figures say.

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 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 right through to final disposal, with the aim of reducing harmful gas emissions.

The Atag IS 18 is rated "A".

Am I covered if the Atag IS 18 system boiler breaks down?

The Atag IS 18 boiler comes with a parts and labour warranty lasting 14 years.
