FIREBIRD LIGHT COMMERCIAL CASCADING SYSTEM

LIGHT COMMERCIAL HEATING SOLUTIONS FROM A SINGLE SOURCE.

The 2009/125/EC Directive states: “Boilers with rated heat outputs greater than 70kW (and less than 400kW) that are installed in new builds or as refurbishment projects MUST comply with the directive and achieve greater than 86% GCV”.

Can Firebird help to meet the Directive requirements - Absolutely Yes!

Firebird condensing boilers have been designed to be as efficient as possible so not only can the directive be met, significant operational cost savings can also be made when using modern Firebird oil fired condensing boilers, compared with older cast iron single output units currently found in light commercial situations (up to 20%).

Light commercial projects such as nursing homes, small hotels and schools, have always relied upon large single unit standard efficiency boilers – predominantly manufactured from cast iron. These new directives provide new challenges for the existing industry.

Alternatives when planning for the provision of heating systems in light commercial projects will have to be considered:

Linking boilers into a management cascade system can deliver significant efficiency gains as the system can reduce overall boiler output, dependent on demand.

By smart thinking and design, the use of smaller boilers and management systems can significantly reduce capital cost compared with large single source heating units.

HOW IT WORKS

For larger heat demands, all Firebird high efficiency condensing boilers can easily be multi cascaded (modulation) through the Low Loss Header Management System.

These cascade units can provide a condensing output of up to 400kW (possibility of up to 600kW) with the ability to reduce overall output down to a ratio of 1:4. This ensures efficiency is maintained even when demand is low.

The controller manages the boilers to deliver heat to the Low Loss Header, depending on demand from the Low Loss Header.

MULTI BOILER CASCADE SYSTEMS

For larger heat demands, the Enviromax boiler range can be easily combined as part of a multi boiler cascade system. When used in combination with the Low Loss Header, 2 – 4* boilers can be connected. 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, evenly spreading their usage.
