GB162 overview

Our GB162 boiler is perfect for both large domestic and commercial applications and can be installed on its own or as part of a multi-boiler 'cascade' system.

Features & Benefits

Can automatically modulate its output down to 30% or less in order to precisely match the demand for heat
Cascade outputs up to 800kW with tailor made frame kits to suit
Any combination of 1 to 8 boilers can be connected either in-line (TL) or back-to-back (TR)
Extremely compact space-saving cascades (400kW in just 1m²)
Cascaded boilers can be sequenced to come into and out of operation when required.
Ultra low NOx emission levels
GB162 80kW and 100kW models are registered on the Carbon Trust’s ECA scheme (Enhanced Capital Allowance)
Compatible with intelligent, modular Energy Management System controls and BMS interfaces
Intuitive user controls
Cascade kit includes: Mounting frames, support legs, main gas pipe, flow and return headers (reversible for either left or right orientation), low loss header, boiler connecting pipe work, full insulation
