Description

The GB162 65kW can automatically modulate its output down to less than 20% in order to precisely match the demand for heat. This reduces fuel consumption and improves overall seasonal efficiency considerably.

It’s fully compatible with the Energy Management System (EMS) modular controls platform, optimising performance by keeping the boiler in condensing mode for as long as possible. EMS also provides comprehensive heating system functionality and ensures minimal energy usage at all times.

NOx (at 0% oxygen, dry mg/kWh): 28
Net efficiency (temperatures of 50/30°C): 108.0%
Seasonal efficiency (as L2B): 95.5%
