Why choose an ATAG boiler

ATAG boilers are made from high-quality brass and stainless steel components. ATAG boilers are designed to incorporate what ATAG calls their revolutionary unique iCon heat exchanger, which offers unrivaled performance levels and efficiency.

If you’re looking for a new boiler that is different from the mould, then the ATAG range with the iCon heat exchanger is made of high-grade stainless steel and retains 98% of its original efficiency levels over its life span. We have a separate blog that provides more details about heat exchangers and their working.

ATAG boilers emit the least NOx emissions of any gas boiler on the market. This means they are more friendly to the environment than other types of boilers.

ATAG Boiler Reviews

ATAG is a leading boiler manufacturer and their Trustpilot has more than 3.9k reviews for ATAG and an amazing score of 4.8 stars from 5. In addition, 98% of ATAG boiler reviews are above-average.
We are supported by the contrast in ATAG Trustpilot reviews.

ATAG makes what types of boilers?

Combination boilers

Combination (combi boilers) provides central heating and instantaneous water without the use of a hot water tank. The latest ATAG heating technology means modern combi boilers are capable of meeting the needs of multiple bathrooms. Our engineering excellence can save you up to £580 per year on your gas bill (Energy Saving Trust April 2022).

System boilers

Traditional ATAG system boilers come with an unvented hot cylinder, which increases the hot water capacity. It is a space-saving solution because the controls and pump are all contained in the boiler casing. An ATAG iS boiler is one of the most efficient in Europe. You’ll also love its simple operation. Unlike the regular boiler, they do not need a cold water storage tank.

Regular boilers

These boilers are also known as regular boilers and can be found in many homes across the UK. Regular boilers are a straightforward and easy way to replace your boiler. They require a loft space for the Cold water storage tank and feed. There are many sizes available for regular boilers.

ATAG Combi Boiler Range

At the moment, seven ATAG combi boilers are available. They are part of two exclusive gas boiler selections: the iC Economiser and iC Economiser PLUS combi boilers.

This is the flagship combi boiler range by the brand, and one of the most sought-after models offered by ATAG offering maximum energy efficiency.

A combi boiler is a combination of a central heating and water heater in one unit. This eliminates the need for additional hot water cylinders, cold water cisterns, or other boilers.

Combi boilers can run on various fuels so they can be used in both grid-connected and off-grid properties. Below are the compatible fuels for a combi boiler.

ATAG Economiser range

Each ATAG boiler comes with a standard 10 year warranty, and options for up to 14 years. They are professionally installed by ATAG Selected Partners.

This is the ultimate in domestic efficiency.

Because it includes a revolutionary innovation, the patented Economiser PLUS, the combi boiler of the future, the iC Economiser plus boiler has been called the combi of the Future.

ATAG’s engineers realized that there was still heat in the boiler’s waste flue gasses, which was not being used to heat water. They set out to harness the energy lost and created the ATAG Economiser.

It captures the waste energy from flue gases and then uses it to heat the mains water to increase hot water production efficiency. This saves both money and heat.

You can pair the ATAG iC Economiser PLUS combination boiler with either the ATAG ONEZone smart control or TadoV3+ to get the highest A+Energy Related Products rating.

ATAG boilers prices

An ATAG new boiler cost £1,100 even for their entry level models, which makes them quote expensive to buy. However, in terms of what you get in a boiler, they are quite good value for money, and ATAG are more than confident in saying that their boilers should last around 20 years. Most combi boilers only last 10-15 years.
