GB162 80kW
Description
The GB162 80kW can automatically modulate its output down to less than 25% 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): 37
Net efficiency (temperatures of 50/30°C): 110.0%
Seasonal efficiency (as L2B): 95.7%
Efficiency
- Net efficiency (NCV) 110%
Features and benefits
- Condensing technology with up to 110% net efficiency - saves fuel compared to standard efficiency boiler
- Modulation to just 20% of total output - year-round efficiency according to seasonal demand
- Cascade outputs up to 800kW per frame kit - modular package providing energy saving flexibility and maintenance backup
- Extremely compact cascades (400kW in just 1m2) - space saving
- Award winning ALU-Plus heat exchanger - added durability and low cost servicing
- Ultra low emission levels - cleaner combustion and increased carbon savings
- Quick and easy installation - time saving
- Integrates with solar thermal installations - maximises savings from solar hot water
- Individual lift weight starting at only 70kg - aids installation
- Whisper quiet - can be sited near occupied rooms
- Intuitive user controls - increased system functionality and reduced running costs
- LPG conversion available - ideal for off-mains-gas locations
