Ariston Boiler Review

A global leader in thermal comfort, now part of the Ariston Group with a strong UK presence. Renowned for its innovative and stylish heating solutions, Ariston combines over 90 years of expertise with cutting-edge technology to deliver efficient boilers tailored for modern lifestyles. In 2025, Ariston’s combi boilers, including the Alteas One Net, Clas One, and E-Combi One, are celebrated for their sleek design, smart connectivity, and high efficiency, making them a favorite for UK homeowners seeking premium performance. Ariston combi boilers provide instant hot water and central heating from a single unit, eliminating storage tanks, ideal for flats or medium-sized homes. Models like the Alteas One Net (24kW–38kW) achieve A-rated efficiency of ~90–94%, with flow rates of ~10–15 liters per minute, suitable for 1–2 bathrooms. Featuring stainless steel heat exchangers, they ensure durability and low emissions. Compact (some as small as 745mm x 400mm x 315mm) and wall-mounted, they blend into kitchens with elegant, Italian-inspired aesthetics. Advanced features include Ariston’s SENSYS Net interface, Cube S Net Wi-Fi controls, and compatibility with the Ariston NET app for remote management, alongside 20% hydrogen-readiness. Installer-friendly with flexible flue options, they offer 4–12 year warranties via accredited installers. Priced from £650–£1,800 (excluding installation), they balance quality and cost, though some Trustpilot reviews (4.4/5 from 4,000) note occasional delays in customer support. Best for small to medium homes, larger properties may require Ariston’s system boilers. With awards like Red Dot for design and a focus on low-NOx sustainability, Ariston remains a stylish, eco-conscious choice.
