The ecoTEC plus 48kW light commercial wall-hung boiler range is a compact, high-efficiency solution designed for commercial applications where space is at a premium. Built in Vaillant's award-winning Derbyshire manufacturing plant, this boiler offer flexibility, ease of installation, and exceptional reliability for a range of projects.

Why Choose a Light Commercial Boiler?

Designed for larger residential properties and commercial premises, the ecoTEC plus 48kW provides high-output heating in a compact form. Ideal for businesses, schools, and apartment blocks, these boilers can be cascaded for higher outputs, making them a versatile alternative to bulky commercial boilers.

Features:

• Compact design – Smaller dimensions and lighter weight of only 38kg, make installation easier, even in restrictive spaces.
• High-efficiency stainless steel heat exchanger – Provides exceptional performance, lower running costs, and an ErP A+ efficiency rating.
• Compatible with cascade installations – Can be installed in multiples on a wall or rig system for larger premises with high heat demand.
• Natural gas and LPG compatibility – Can be converted to LPG for projects without a mains gas supply.
• Internal ducted rain collector – Prevents rain ingress from the flue system, protecting electrical components inside the boiler.
• Gunmetal air separator with system pressure gauge – Reduces unwanted vented emissions, with a removable front cover for easy maintenance.
• Hydrogen-ready – Successfully tested with up to 20% hydrogen blend as part of the HyDeploy project, ensuring future-proof low-carbon heating.
• Plate heat exchanger required for cascade installations where net output exceeds 70kW.
