GB162 cascades

Description

The GB162 can be easily combined as part of a multi-boiler cascade system for larger heating demands.

Any combination of 1 to 8 boilers can be connected either in-line (TL) or back-to-back (TR), to provide condensing boiler outputs of up to 800kW with the ability to modulate down to as low as 2.5% of total output. This ensures that high levels of efficiency can be achieved all year round, even when demand for heat is low.

Boilers can be sequenced to come into and out of operation when required.

The GB162 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

Features and benefits

• Condensing technology with up to 110% net efficiency - saves fuel compared to standard efficiency boiler
• Cascade outputs of up to 800kW per frame kit - modular package providing energy saving flexibility and maintenance back-up
• Extremely compact cascades (400kW in just 1m squared) - space saving
• Modulation to just 20% of total output - year-round efficiency according to seasonal demand
• No minimum flow rate required
• 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
• 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
