ATAG Boilers Boiler Efficiency Rating, Repair & Service

ATAG Boiler Efficiency Page

ATAG have been setting increasingly high energy efficiency standards since they were established almost 70 years ago. Grown to now operate in many countries, their boilers are providing heating and hot water to commercial and domestic settings around the world.

Their i-Series range of boilers, that includes Combi, System and Regualr boilers are incredibly efficient thanks to being fitted with their very own iCon heat exchanger. This component provides great performance and high levels of efficiency by maintaining 98% of its efficiency levels during its lifetime.

Every single one of their boilers comes with a 10 year warranty as standard and will be installed by ATAG Selected Partners.

iC Economiser Plus Combination Boilers

Fitted with ATAG’s patented Economiser, a very innovative component, the iC Economiser Plus boiler have been described as ‘the combi of the future’. The Economiser recycles untapped residual heat in the boiler after hot water has been heated instead of releasing it as waste, as would happen previously.

Thanks to this technology these Combi boilers achieve an ErP A rating and could potentially save you up to £320 on your gas bills every year.

The models available in this range are the iC Economiser Plus 39, iC Economiser Plus 35 and the iC Economiser Plus 27. The numbers at the end of the model names represents the output available, so the 39kW and 35kW models are ideal for large homes with more than one bathroom.

All of these boilers come with a 10 year warranty as standard so you know you’ll be investing in a reliable boiler.

iC Combination Boilers

Whether you live in a small home with one bathroom or a large home with more than one bathroom, there’s a Combi boiler in this range to fit the needs of your home. Available in outputs of 24-40kW with a flow rate of 10.1-16.2 litres per minute, these Combi boilers also run nice and quietly.

Featuring a 10 year warranty, they’re also fitted with the iCon Heat Exchanger that has a lifetime replacement guarantee.

iS System Boilers

To make these System boilers highly efficient and save you money on your bills, they’re fitted with an Erp pump that controls the amount of heat that’s being given out by the boiler. Due to this feature, it’s no surprise that these System boilers have achieved an ErP A rating. You can even increase the efficiency of these boilers further by combining them with an iSteel hot water cylinder.

iR Regular Boilers

Available in outputs ranging from 15-40kW, there’s a boiler in this range that’s capable of meeting the hot water demands for the vast majority of homes. All the models reach an ErP A rating and come with a standard 10 year warranty, making these the perfect choice if you’re looking to replace your current Regular boiler.

How Much Does an ATAG Boiler Cost?

ATAG’s range of Combi, System and Regular boilers can come in at a price of between £700 and £2500. These estimates don’t include the cost of installation which will differ depending on the engineer carrying out the work, and that’s why we recommend getting 3 quotes before picking an engineer to get the best deal for you.
