Zanussi Boiler Review

Grown from crafting wood-burning stoves into a global leader in home appliances under the Electrolux Group since 1984. Renowned for quality, innovation, and contemporary design, Zanussi entered the UK boiler market with its Ultra Combi and Ultra System ranges, offering efficient heating solutions for modern homes. In 2025, these boilers, notably the Ultra Combi (30kW and 35kW), are valued for their compact design and high efficiency, though they are rebranded Ideal boilers, which has sparked some consumer debate. Zanussi combi boilers deliver instant hot water and central heating without external storage tanks, ideal for small to medium-sized homes with 1–2 bathrooms. Achieving A-rated efficiency of ~93%, they feature stainless steel heat exchangers, frost protection, and a Honeywell gas valve for reliability. Compact (fitting kitchen cupboards at ~32kg) and wall-mounted, they offer sleek aesthetics and Wi-Fi controls via the Nest app. Installer-friendly with flue options and a built-in filling loop, they come with a 10-year warranty, though registration by a Gas Safe engineer is required. Priced from £660–£780 (installation £500–£1,600), they’re cost-effective, but Trustpilot reviews (average 3.5/5) cite concerns over rebranding and after-sales support. Best for modest hot water needs, larger homes may prefer Zanussi’s system boilers with external cylinders. With ErP compliance and low-NOx emissions, Zanussi remains a practical, eco-conscious choice.
