Atag iS 15 System Gas boiler frequently asked questions

What type of boiler is Atag’s IS 15 - system, regular or combi?

If you are searching for a system boiler for your house or flat, the Atag IS 15 is certainly one to consider.

System boilers require a hot water cylinder to work (normally stored in an airing or landing cupboard) but, unlike heat only boilers, they do not require a cold water tank. This makes them more suitable for homes that do not have lofts, where attic space is limited or where a loft conversion is being considered.

You program your heating and hot water to come on via the control panel. But if you forget to set the timer, you will have to wait a while for the water to heat up. Hot water is stored in the cylinder for use throughout the day and can be distributed to multiple showers and taps at the same time without a loss of pressure or temperature (something combi boilers really struggle with). For this reason, a system boiler is a suitable option for large families and homes with more than one bathroom.

As no cold-water tank is needed with a system boiler and many major system components are built into it, this type of boiler can be easier to install than a standard boiler.

Should I choose a Atag IS 15 system boiler for my house or flat?

Whether this Atag iS 15 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 15 system outputs at a maximum of 14 kW, so which types of property would this Atag iS 15 System boiler be appropriate for?

A heating engineer would recommend that the Atag IS 15 system boiler would be a suitable installation option for smaller homes and apartments with up to 10 radiators and one bathroom.


The size of the Atag IS 15 in millimetres

The Atag IS 15 stands at TBC mm tall, TBC mm wide and TBC mm deep.

Is this Atag boiler non-condensing or condensing?

Condensing gas boilers like the Atag IS 15 are more energy-efficient and choosing one for your home will cut the amount you pay every year for your gas.

They do this by capturing the heat in water vapour condensation and in exhaust gases which would normally be expelled via the flue. They then recycle that heat, returning it to the system to, among other tasks, reheat colder water that is returning to your boiler from your radiators.

Is the Atag IS 15 system boiler good for the environment?

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.

We generate 14% of UK greenhouse gas emissions through centrally heating our domestic properties. Gas boilers are mainly responsible for harmful nitrogen dioxide emissions in larger British cities.

Let's take a closer look at whether installing a Atag IS 15 system would be a good choice for the environment.

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 Atag IS 15 was given an efficiency rating of 93% and a band rating of "A".

The Energy Related Products Directive intends to encourage all manufacturers to reduce harmful gas emissions connected to the products they make, from the manufacturing stage to final disposal, including when they are in active use.

The Atag IS 15 has an ERP rating of "A".

What warranty does the Atag IS 15 system boiler come with?

The Atag IS 15 boiler offers a parts and labour warranty of 14 years.

Atag iS 15 System Gas boiler frequently asked questions

Is the Atag IS 15 a standard, combi or system boiler?

The Atag IS 15 boiler is a system boiler you may wish to consider when looking for a new boiler for your house or flat.

Ever since system boilers arrived on the market, they have been a popular choice in new homes. In the same way as regular boilers, they work along with a hot water cylinder, which is usually located in an airing cupboard. Since system boilers do not require a separate cold water tank, they appeal to some homeowners, especially if they intend to convert their loft in the future.

Their design includes (often built-in) circulating pumps to send hot water to your taps and radiators. They're also quicker and easier to install because you don't need to find room for and fit a water storage tank.

In addition, system boilers require programming for the flow of heat and hot water, which is not available right away. In any case, the cylinder keeps the water hot for use later, so you shouldn't have to wait for your bath as long as you set your timer and leave it on for long enough to heat sufficient water to use throughout the day.

Is the Atag IS 15 system boiler from the IS range a suitable choice for my house or flat?

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

The amount of hot water you get from showers, bathrooms, and sinks and heat from your radiators depends on your boiler's output (measured in kilowatts). The higher the level of output, the better your home will be heated and you can be more certain that the water from your taps will be as hot as you want.

However, you must be careful. You might not get the hot water you want if your boiler output is too low. If it's too high, you'll be paying more than you need to for gas.

With the Atag IS 15 system's output at 14 kW, which types of property would this Atag iS 15 System boiler be most appropriate for?

A PlumbProud Gas Safe boiler installer would recommend that this Atag iS 15 System boiler be installed in smaller homes and apartments with one bathroom and up to 10 radiators.


What dimensions does a Atag IS 15 have?

The Atag IS 15 is TBC mm high by TBC mm wide by TBC mm deep.

Is the Atag IS 15 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 15 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.

How environmentally friendly is the Atag IS 15 system?

As the British public has become more conscious of climate change, many homeowners consider the environment when choosing how to heat their homes.

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.

Would choosing a Atag IS 15 system help in the fight against climate change? What do the performance statistics suggest?

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 15 has been assigned an efficiency rating of 93% with a SEDBUK rating of "A".

In 2015, new legislation was introduced by the EU to encourage manufacturers to develop more energy-efficient products that emit fewer harmful gases throughout their lifetime.

The Energy Related Products Directive (ERP) applies to all products that consume energy, including during the manufacturing process, at the point of final disposal, and all points in between.

The ERP rating of the Atag IS 15 is "A".

Is there a warranty on the Atag IS 15 system boiler if it breaks down?

You receive a parts and labour warranty of 14 years with the Atag IS 15 boiler.
