Atag iC Economiser 27 Combi Gas boiler frequently asked questions

Is the Atag IC Economiser 27 a system boiler, a combi boiler or a regular boiler?

The Atag IC Economiser 27 boiler is a combi boiler you may wish to consider when looking for a new boiler for your house or flat.

Combi boilers have much to recommend them - not least the fact that they save a lot of space. Combination (or combi) boilers were introduced by manufacturers in the 1970s to provide practical central heating and hot water distribution to smaller properties - remember that UK houses and flats tend to be among the smallest in the developed world.

Traditional boilers require one or more storage tanks to keep hot water warm and to store water for heating later. In contrast, combi boilers draw water directly from the mains supply and heat it instantly, removing the need for a storage tank. The heated water is then distributed to your taps and radiators on demand.

While combi boilers are suitable choices for many properties, especially those without a loft, there is also a disadvantage in using them. Water is heated instantly and the volume of water that can be heated at any one time is limited. This can result in less water being sent to taps and showers if more than one is being used simultaneously. In these instances, the water pressure to both points will drop.

Should I install a Atag IC Economiser 27 combi boiler in my home?

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 IC Economiser 27 combi boiler has an output level of 23 kW, so which types of property would it be appropriate for?

Most Gas Safe boiler installers would recommend that this Atag iC Economiser 27 Combi boiler would be suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

In addition to output rates, you need to consider a combi boiler's flow rate when making your choice.

The flow rate of your boiler dictates the maximum volume of water (measured in litres per minute) that it can heat and distribute to your taps, showers and radiators at any one time.

However, a combi boiler like the Atag IC Economiser 27 can only heat and deliver water at the rate at which it actually enters your property. For this reason, you should also find out what the mains pressure to your house is before purchasing a boiler.

It's pointless spending more money on a boiler with a 17l/m flow rate if the local water pressure is 11l/m. To give you an indication of average water demand, a power shower typically requires 12 litres of water per minute and a basin tap 4-8 litres. This Atag iC Economiser 27 Combi boiler's flow rate is 13 L/m.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


What size is the Atag IC Economiser 27 boiler?

The Atag IC Economiser 27's dimensions are TBC mm [H] x TBC mm [W] x TBC mm [D].

Is the Atag IC Economiser 27 non-condensing or condensing?

We recommend that, if possible, you select one of the very latest condensing gas boilers on the market like the Atag IC Economiser 27.

Condensing boilers are better for the environment because they capture and recycle the heat still present in flue exhaust gases and water vapour condensation for re-use, meaning lower greenhouse gas emissions.

They're also a lot cheaper to run meaning that, if you're replacing a very old and inefficient boiler, the savings on your gas bill over 5-10 years add up to more than you pay for the boiler itself.

Is the Atag IC Economiser 27 combi 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.

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.

If you would like your next boiler to help in the fight against climate change, would the Atag IC Economiser 27 combi be a suitable choice?

All boilers manufactured in the UK from April 2018 must operate at a minimum level of energy efficiency of 92% ("A" rating on the SEDBUK scale). Before that, the minimum was 88% - boilers scoring 88/89% were given a SEDBUK "B" rating and 90% or above an "A" rating.

The energy efficiency score of a boiler indicates how much energy it uses and how much goes to waste when in use.

After its assessment, the Atag IC Economiser 27 was given an efficiency rating of 94% and a SEDBUK grading of "A".

The Energy Related Products (ERP) Directive is important European legislation that aims to limit energy use and harmful gas emissions during the manufacturing process, when the product is in use, and after it is disposed of.

For the Atag IC Economiser 27, the ERP Heat rating is "A" and the ERP Water rating is "A".

Atag iC Economiser 27 Combi Gas boiler frequently asked questions

Atag IC Economiser 27 - a regular boiler, combi boiler or system boiler?

If you are considering installing a combi boiler in your house or flat, then the Atag IC Economiser 27 boiler is certainly worth investigating.

A combi boiler could be a better choice than a standard boiler if space is at a premium in your home. Combi boilers draw water directly from the mains supply and heat it instantly, removing the need for a hot water cylinder and a cold water tank.

Water is heated on demand and then distributed directly to your taps and showers. This means that combi boilers use less fuel and so reduce your gas bills.

The main disadvantage to combi boilers is that they can only heat a limited volume of water at any given time. If more than one tap or shower is in use, the hot water supply to both could be restricted and both the water pressure and temperature will drop.

Would the Atag IC Economiser 27 combi be a suitable choice of 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 IC Economiser 27 combi boiler has an output rate of 23 kW, so which types of property would this be suitable for?

An experienced PlumbProud Gas Safe engineer would almost certainly recommend that this Atag iC Economiser 27 Combi boiler would be most suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

As well as the output rate, you need to consider "flow rate" when choosing a combi boiler.

The flow rate describes how much water a combi boiler can draw from the mains, instantly heat, and then send to your radiators. Flow rates are measured in litres per second and this Atag iC Economiser 27 Combi boiler's flow rate is 13 L/m.

The water in your mains pipe also has its own flow rate - normally between 10 and 12l/m in most parts of Britain. This means that, if you choose a combi boiler with a flow rate of 17l/m where local water pressure is 11lm, it won't actually process more water because of the slower flow rate of the mains.

In addition, larger households with more than one bathroom, multiple radiators, and where family members may want to use hot water at the same time (like morning showers) may actually need a boiler with a higher flow rate than either the boiler or the local mains pipe.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


Making space for the Atag IC Economiser 27

The measurements of the Atag IC Economiser 27 are TBC mm by TBC mm by TBC mm.

Is the Atag IC Economiser 27 condensing or non-condensing?

We recommend that, if possible, you select one of the very latest condensing gas boilers on the market like the Atag IC Economiser 27.

Condensing boilers are better for the environment because they capture and recycle the heat still present in flue exhaust gases and water vapour condensation for re-use, meaning lower greenhouse gas emissions.

They're also a lot cheaper to run meaning that, if you're replacing a very old and inefficient boiler, the savings on your gas bill over 5-10 years add up to more than you pay for the boiler itself.

Is the Atag IC Economiser 27 combi boiler good for the environment?

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.

14% of the UK’s greenhouse gas production comes from central heating. In the bigger cities, gas boilers in particular are responsible for dangerous levels of nitrogen dioxide emissions.

If you decide to install a Atag IC Economiser 27 combi in your home, will you be helping the environment with your choice? Let’s have a look at the figures.

Boilers manufactured after April 2018 in the UK must achieve an "A" on the SEDBUK grading system as well as score a minimum of 92% on a separate energy efficiency test. Prior to that, the minimum was 88% - boilers rated at 88% and 89% were given a “B” rating (90% and higher were given an "A").

An energy efficiency rating describes how much energy the boiler uses and how much it wastes when in use.

The Atag IC Economiser 27 was awarded an efficiency rating of 94% with a SEDBUK grading of "A".

The Energy Related Products (ERP) Directive is important European legislation that aims to limit energy use and harmful gas emissions during the manufacturing process, when the product is in use, and after it is disposed of.

For the Atag IC Economiser 27, the ERP Heat rating is "A" and the ERP Water rating is "A".

Is this Atag IC Economiser 27 combi covered by a warranty?
