Atag Boiler Review

ATAG is a trusted brand known for its efficient combi boilers. The original E-Series and Q-Series models are outdated. In 2025, ATAG offers the iC Combination and iC Economiser ranges, which are compact, stylish, and technologically advanced. ATAG’s current lineup includes multiple combi boiler models. The iC Combination series has 27kW, 35kW, and 39kW options, while the iC Economiser series offers similar outputs with enhanced efficiency. These cater to various home sizes. The iC Combination 27kW suits small homes with one bathroom, delivering a 12.6 liters per minute flow rate. It’s efficient and ideal for apartments or modest households. The iC Combination 35kW provides a 16.1 liters per minute flow rate, perfect for medium homes with up to two bathrooms. It balances performance and energy savings. The iC Combination 39kW is designed for larger homes, offering a 17.0 liters per minute flow rate. It handles multiple bathrooms with ease. The iC Economiser 27kW matches the 27kW iC’s flow rate but uses Economiser Plus technology to boost efficiency by recycling heat from flue gases. The iC Economiser 35kW delivers a 16.1 liters per minute flow rate, ideal for medium to large homes. It’s highly efficient, reducing energy costs. The iC Economiser 39kW is the top model, with a 17.0 liters per minute flow rate, perfect for large homes with high hot water demands. ATAG produces these models to meet diverse needs. Unlike the old E-Series and Q-Series, they don’t use storage tanks, saving space and simplifying installation. The boilers come in different power settings. The 27kW models suit small homes, while 35kW and 39kW options are better for larger properties. Powerful models like the 39kW Economiser are great for big families or homes with multiple bathrooms, yet they remain compact for easy installation. Even larger ATAG boilers take up minimal space. Their wall-mounted design fits in kitchens or utility rooms, ideal for small spaces. All ATAG boilers are stylish, with a sleek, modern look. They blend well into contemporary homes, combining aesthetics with functionality. ATAG boilers deliver great heating performance. The iCon stainless steel heat exchanger ensures durability and maintains 98% efficiency over time. The iC Combination series works like a traditional combi boiler, heating water directly from the mains. It’s efficient but may slow during simultaneous use. The iC Economiser series improves hot water delivery with heat recovery technology, offering better performance for busier households without a tank. The iC Combination 27kW and 35kW models are cost-effective, with A-rated efficiency. They provide ample hot water for most homes unless heavily used. The iC Economiser series is ideal for larger houses or homes with multiple bathrooms, delivering consistent hot water even during peak demand. ATAG boilers are excellent for heating and hot water, highly efficient, and eco-friendly, with low NOx emissions and minimal carbon footprint.
