Biasi Boiler Review

Known for affordable and compact heating solutions, Biasi operates a 64,000-square-foot facility, producing reliable boilers for domestic and commercial use. In 2025, Biasi’s combi boilers, including the Advance, Advance Plus, Advance Plus 7, and Basica ranges, are valued for their efficiency and budget-friendly pricing, catering to UK homeowners seeking cost-effective heating. Biasi combi boilers deliver instant hot water and central heating from a single unit, eliminating the need for storage tanks, making them ideal for flats or small to medium-sized homes. Models like the Advance Plus (25kW–35kW) offer A-rated efficiency of ~92%, with flow rates of ~12–15 liters per minute, suitable for 1–2 bathrooms. Featuring high-grade stainless steel single-coil heat exchangers, they ensure durability and resist debris buildup. Compact (some as small as 700mm x 400mm x 300mm) and wall-mounted, they fit kitchen cupboards, with user-friendly controls and modern aesthetics. Advanced features include built-in frost protection, weather compensation, and optional mechanical clocks, with some models offering self-rectifying technology. Installer-friendly with flue options up to 10 meters, they provide 5–7 year warranties, though registration within 30 days is required. Priced from £469–£1,213 (excluding installation of £800–£1,300), they’re economical, but Trustpilot reviews (3.9/5 from 581) note issues like water pressure or after-sales delays, with 25% rating 3 stars or less. Best for smaller homes, larger properties may need Biasi’s system boilers.
