Potterton Boiler Review

Acquired by Baxi Heating in 1999 and part of the BDR Thermea Group, Potterton pioneered the UK’s first gas boiler, the Diplomat, in 1955, and introduced wall-hung boilers in 1970, revolutionizing home heating. In 2025, Potterton’s combi boilers, including the Titanium, Gold, and Assure ranges, are celebrated for their reliability, efficiency, and affordability, heating over 7 million UK homes. Potterton combi boilers deliver instant hot water and central heating from a single unit, eliminating the need for storage tanks, making them ideal for compact homes like flats or terraces. Models such as the Titanium (24kW–40kW) offer A-rated efficiency of 91–93%, with flow rates of ~10–16 liters per minute, suiting small to large homes. Their lightweight, wall-mounted designs fit kitchen cupboards, blending sleek aesthetics with functionality. Features like frost protection, smart controls (e.g., Baxi uSense), and 20% hydrogen-readiness ensure modern appeal. Installer-friendly with flue options up to 20 meters, they come with warranties of 2–7 years, extendable with annual servicing. While praised for value (£600–£1,500), some Trustpilot reviews note occasional pressure issues in older models like the Promax. Best for small to medium homes, larger properties with multiple bathrooms may prefer Potterton’s system boilers. Backed by Baxi’s robust support and Which? Best Buy awards for the Gold range, Potterton remains a trusted, cost-effective choice for efficient, durable heating.
