Atag iS 40 System Gas boiler frequently asked questions

What type of boiler is the Atag IS 40?

You may wish to consider installing the Atag IS 40 if you are looking for a system boiler for your house or flat.

System boilers are very popular for properties with limited or no loft space or when homeowners want to keep the space for a loft conversion. This is because, unlike heat only boilers, they don’t require a cold-water tank - however, system boilers do need a hot water cylinder (often installed in an airing or landing cupboard).

Instead of the traditional cold-water tanks, system boilers use their built-in circulating pumps to heat the water needed for your taps and radiators. This also makes them an easier choice for engineers to install as there is one less large component to find space for and fit.

Like a regular boiler, you need to use a control panel to control a system boiler. Set the times when you want central heating and hot water to be available, such as in the morning when there might be greater demand for showers, and it will be there. Although hot water is not available on-demand like with a combi boiler, once the water has been heated it will stay in the hot water cylinder until it’s used up.

Would the Atag IS 40 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.

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 IS 40 system is 38 kW, so which types of property would this Atag iS 40 System boiler be an appropriate choice for?

An experienced Gas Safe boiler installer would be likely to recommend that this Atag iS 40 System boiler is capable of providing heating and hot water to 15 or more radiators and two or more bathrooms and would therefore be most suitable for larger properties including detached homes.


The size of the Atag IS 40 in millimetres

The Atag IS 40 boiler is TBC mm high, TBC mm wide, and TBC mm deep.

Is the Atag IS 40 a condensing or non-condensing boiler?

Condensing gas boilers like the Atag IS 40 are environmentally friendlier and cheaper to run so, if possible, we strongly recommend that you choose this or one of the very latest models.

Condensing boilers are much more efficient and economical to run because they contain a secondary heat exchanger that captures and recycles the warmth still present in the flue exhaust gases and the water vapour condensation for re-use, meaning that they use less gas to run.

Does the Atag IS 40 system protect the environment?

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.

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.

Would choosing the Atag IS 40 system help the environment? Let's see what the statistics suggest.

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 40 was given an efficiency rating of 94% and a band rating of "A".

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

The aim is to encourage companies to create environmentally friendlier products that reduce harmful gas emissions during manufacturing and when in use by the end client, right through to their eventual disposal.

In the case of the Atag IS 40, the ERP rating is "A" for heat and "A" for hot water production.

Is this Atag IS 40 system covered by a warranty?

The Atag IS 40 is supplied with a parts and labour warranty of 14 years.

Atag iS 40 System Gas boiler frequently asked questions

Is the Atag IS 40 a combi, system or regular boiler?

Suitable for a house or a flat, the Atag IS 40 system boiler is worth considering if you want a system boiler.

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

Combi boilers heat water on demand but the amount of water they can actually deliver to taps is determined by the mains water pressure, flow rate and power. System boilers instead use a hot water cylinder that stores and keeps water hot throughout the day. As long as you remember to program the times you want hot water and the cylinder still has water left in it, 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.

Should I install a Atag IS 40 system boiler in my house or apartment?

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

Your boiler’s output is a measurement of the power it has available to it to heat the water you need for your radiators or for when you turn on a tap, bath or shower. A higher output rate means it has more power and can heat more water.

It's important to choose an output that matches the demand for water in your home because if your boiler has too low an output, you'll often find only lukewarm water comes out of your taps or heats your radiators. If it’s too high, you’ll be paying more for your gas than you need to.

The Atag IS 40 system has an output of 38 kW, so which types of property would this Atag iS 40 System boiler be appropriate for?

An experienced Gas Safe boiler installer would recommend that this Atag iS 40 System boiler would be a suitable installation choice for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


The size of the Atag IS 40

The Atag IS 40 is TBC mm high by TBC mm wide by TBC mm deep.

Atag IS 40 – non-condensing or condensing?

Condensing boilers convert the warmth present in flue exhaust gases and water vapour condensation into heat which they then recycle to increase the temperature of the colder water returning to your system.

We recommend that homeowners choose a condensing boiler like the Atag IS 40 for this reason - the more recent your model the better because the technology improves every year.

You'll benefit from lower quarterly gas bills and condensing boilers are also much more environmentally friendly.

Is the system Atag IS 40 boiler energy efficient?

With more and more of us concerned about environmental issues and climate change, how we heat our homes has become an important issue to many homeowners.

Central heating systems are responsible for 14% of greenhouse gas emissions in the UK. You may also be aware that the gas boilers we use emit dangerous nitrogen dioxide in large volumes in the bigger British cities.

Would choosing a Atag IS 40 system help the environment? Let’s see what the performance figures suggest.

Boilers manufactured or supplied to UK domestic properties must achieve a legal minimum energy efficiency rating of 92% (equivalent to a good "A" grade using the SEDBUK scale). Prior to this, the minimum was 88% (88% and 89% are a "B" SEDBUK grade and anything 90% or above is an "A" grade).

The energy efficiency rating of a boiler refers to the amount of energy it uses to perform its everyday functions as well as the amount of energy it wastes.

The Atag IS 40 has been given a rating of 94% for energy efficiency, equivalent to a SEDBUK "A" rating.

All products that consume energy throughout their lifespan must comply with the Energy Related Products (ERP) Directive.

Companies are legally obliged to reduce harmful gas emissions at all stages of a product's life cycle, from initial manufacturing right through to final disposal as well as when the product is in actual use.

The Atag IS 40 scores "A" for heat and "A" for water.

How long is the warranty period on the Atag IS 40 system boiler?

The Atag IS 40 is supplied with a parts and labour warranty of 14 years.
