Atag iS 15 System Gas boiler frequently asked questions

Is this Atag IS 15 boiler a combi, system or regular boiler?

You may wish to consider installing the Atag IS 15 if you are looking for a system boiler for your house or flat.

If you choose a system boiler, you'll have to find somewhere to install a hot water cylinder too - they're normally located in an airing or landing cupboard. However, unlike regular boilers, they do not require a cold water tank to be fitted in the attic, making them suitable for homes with limited or no roof space or if you're planning a loft conversion in the future.

System boilers distribute the hot water to your taps and radiators using (often built-in) circulation pumps and are easier to install from scratch since they have one less component (the water tank) to consider.

System boilers also require programming to produce heat and hot water, so they cannot produce this instantly. Nonetheless, the cylinder keeps water hot for use later, so you don't have to wait as long as you set your timer and keep it on long enough to heat enough water.

Is the Atag IS 15 system boiler the right choice for my house or apartment?

Whether this Atag iS 15 System boiler is right for your property depends on its size or what its "output" level is. Size does not mean its physical dimensions, however - it means how powerful it is.

The output rating indicates how much energy a boiler can use in providing you with hot water and heat when you need it from your radiators and taps. The greater the output, the more water it can heat.

It's better to take advice on this from a registered installer because, if your boiler output is too low, your water and radiators might not get as hot as you would like them to be. However, if the output level is too high, you'll end up paying more on your gas bills than you need to.

Which types of property would this Atag iS 15 System boiler be appropriate for given its output of 14 kW?

A boiler engineer would recommend that, at this level of output, the most suitable type of property for this Atag iS 15 System boiler would be smaller homes and apartments with up to 10 radiators and one bathroom.


Making space for the Atag IS 15

Atag’s IS 15 is TBC mm tall, TBC mm wide, and TBC mm deep.

Is the Atag IS 15 a non-condensing or condensing boiler?

We recommend that you choose a condensing boiler wherever possible like the Atag IS 15 - try to go for the latest model, if possible, to take advantage of improving technology.

Condensing boilers capture and recycle the warmth still present in the water vapour condensation and in flue exhaust emissions created by burning gas to make them more efficient and economical to run.

You will save money on your gas bills too, plus condensing boilers are friendlier to the environment.

How environmentally friendly is the Atag IS 15 system?

As more of us are increasingly concerned about climate change, how we heat our homes and its impact on the environment has become an issue of importance to homeowners.

14% of the total amount of greenhouse gases produced by the UK comes from the central heating systems we use. In some of Britain's biggest cities, gas boilers create dangerous levels of nitrogen dioxide in the atmosphere.

If you would like your next boiler to help in the fight against climate change, would the Atag IS 15 system be a suitable choice?

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 Atag IS 15 was given a 93% energy efficiency rating and a SEDBUK grading 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 15 is rated "A".

Am I covered if the Atag IS 15 system boiler breaks down?

Atag offers a parts and labour warranty of 14 years on the Atag IS 15.

Atag iS 15 System Gas boiler frequently asked questions

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

You may wish to consider installing the Atag IS 15 if you are looking for a system boiler for your house or flat.

System boilers are suitable for homes with a higher-than-average demand for central heating and water - for example, larger homes and larger families.

Tell the boiler when you want hot water using the control panel - it draws water from the mains, heats it and keeps it warm throughout the day in the hot water cylinder. As long as you remember to tell the boiler when you want hot water, you have a big enough cylinder, and there's not an unusually high demand for water on a particular day, you should have hot water whenever you need it.

System boilers do not require a cold water storage tank either, unlike heat only boilers, meaning they're cheaper, quicker and easier to install.

Is the Atag IS 15 system boiler suitable for my house or apartment?

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?

An experienced boiler engineer would recommend that this Atag iS 15 System boiler would be a suitable installation choice for smaller homes and apartments with up to 10 radiators and one bathroom.


What size is the Atag IS 15 boiler?

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

Is the Atag IS 15 a condensing or non-condensing boiler?

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

Many homeowners are now worried about climate change and the damage they do to the environment from heating their homes has become a subject of increasing concern.

Central heating produces 14% of all greenhouse gas emissions in the UK. Gas boilers in the larger cities emit dangerous levels of nitrogen dioxide.

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 Atag IS 15 was given a 93% energy efficiency rating and a SEDBUK grading of "A".

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.

The intention of this European legislation is 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 IS 15 is "A".

What length of warranty does the Atag IS 15 come with?

The parts and labour warranty on the Atag IS 15 lasts for 14 years.
