The Atag IC Economiser 27 is a combi boiler you may wish to consider if you want this type of boiler for your house or flat.
Combi boilers were introduced by manufacturers in the 1970s to offer British homeowners a way to cheaply and reliably heat their homes and have hot water without taking up too much space. Previously, most boilers had one or more storage tanks, which either heated water and kept it warm or held water to be heated later.
With combi boilers, there is no need to find space for large tanks around your home as the hot water needed for your radiators and taps is available on demand. Combi boilers do this by drawing water from your mains supply, heating it instantly whenever you need it and then distributing it to where it's needed in the home.
The major disadvantage to combi boilers is that they have a maximum capacity for heating water. In a larger household, water pressure, volume and temperature will drop if two or more people are trying to use hot water at the same time.
You should make sure that the boiler you install in your property is the right "size". And size doesn't mean its physical dimensions, size means how much power it has - the "output".
Output measures in kilowatts how much power a boiler can use when heating water for your radiators or taps. The higher the output rate, the more water it can heat.
If the output rate is too low, your hot water might often be only lukewarm, and if it is too high, you will be paying more for your gas than you need to.
The Atag IC Economiser 27 combi boiler has an output of 23 kW, so which types of property would it be most appropriate 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.
If you are thinking about installing a combi boiler like the Atag IC Economiser 27 in your home, you should consider flow rates as well as output rates. This Atag iC Economiser 27 Combi boiler's flow rate is 13 L/m.
The flow rate indicates the maximum volume of water (measured in litres per minute) that your boiler can heat up and send to your radiators, taps and showers at any one time. The more taps and showers that could be in use simultaneously or the greater the number of radiators you have, the higher the flow rate you need.
However, you should establish what the mains pressure is at your property as a combi boiler can only heat the water that comes into your home.
For example, if your mains pressure is 12 litres per minute, your boiler can only heat and distribute hot water at a rate of 12 litres per minute even if it has a higher flow rate capacity. Typically, a power shower will require 10 litres of water per minute.
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.
The Atag IC Economiser 27 measures TBC mm high and TBC mm wide by a depth of TBC mm.
Condensing gas boilers like the Atag IC Economiser 27 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.
With so many of us worried about the environmental impact of our personal choices, the relationship between how we heat our homes and climate change has become an important issue for many homeowners.
Central heating creates 14% of the UK’s greenhouse gases. And in Britain's larger cities, gas boilers are responsible for dangerous levels of nitrogen dioxide emissions.
Would installing a Atag IC Economiser 27 combi boiler in your home help combat climate change? What do the figures suggest?
All boilers manufactured in the UK from April 2018 must achieve a SEDBUK “A” grade and an energy efficiency rating of 92% or above. Before that, the minimum was 88% - efficiency ratings of 88% and 89% were scored a “B” and 90%+ an "A".
A boiler's energy efficiency rating describes how much energy it uses and wastes during its standard operation.
The energy efficiency of the Atag IC Economiser 27 was rated at 94% with a SEDBUK grading of "A".
The Energy Related Products Directive, also known as ERP, is European legislation that intends to reduce energy consumption related to products right from the initial manufacturing process through to eventual final disposal.
The purpose of the directive is to encourage manufacturers to create new products that are kinder to the environment and which result in lower overall harmful gas emissions through a product's entire life cycle.
The Atag IC Economiser 27 has a rating of "A" for heat and "A" for water.
The Atag IC Economiser 27 boiler is covered by a parts and labour warranty of 14 years.

The Atag IC Economiser 27 is a gas combi boiler.
One of the reasons the combi boiler was introduced to Britain in the 1970s was because residential properties are among the smallest in the world. More traditional boilers require one or more large tanks to be stored around the home to function.
A combi boiler is a self-contained unit that draws water from the mains then heats and distributes it instantly and on demand - no tanks are needed.
They are the most popular type of boilers in the UK and offer only one major disadvantage - there is a maximum volume of water that can be heated at any one time. If that limit is exceeded by, for example, two people using a hot water tap at the same time, there will be a drop in water pressure, temperature and volume to both taps.
Whether this Atag iC Economiser 27 Combi boiler is right for where you live 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 of a boiler is measured in kilowatts and indicates how much energy it can use to heat the water needed for your radiators, taps and showers. The greater the output, the more water it can heat.
A boiler whose output is too high will give you hot water and warm radiators but also higher gas bills, whereas a boiler whose output is too low will result in cheaper gas bills but the water might not always be as hot as you want it to be.
The output of the Atag IC Economiser 27 combi is 23 kW, so which types of property would this model be appropriate for?
An experienced PlumbProud boiler engineer would likely recommend this Atag iC Economiser 27 Combi boiler as suitable for smaller homes and apartments with up to 10 radiators and one bathroom.
If you are considering installing a combi boiler in your home, you need to consider the flow rate as well as the output rate.
The flow rate is the volume of water (measured in litres per minute) that your boiler can instantly heat up and send around the home. The more demand in your home for water at the same time (for example, two people taking showers in different bathrooms), the higher the flow rate you'll need.
However, the actual flow rate your boiler can deliver is also determined by your mains water pressure. If you choose a boiler with a flow rate of 16l/m but the mains water pressure is 12l/m, your boiler will only perform to 12l/m. 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.
The Atag IC Economiser 27 is TBC mm in height, TBC mm in width and TBC mm in depth.
We recommend that you choose a condensing boiler wherever possible like the Atag IC Economiser 27 - 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.
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.
Nitrogen dioxide emissions in Britain's largest cities are at dangerous levels and this has been caused by gas boilers. In fact, 14% of the UK’s greenhouse gases are produced by central heating.
