SPECIFIERS’ GUIDE | ALPHA HEATING INNOVATION | ADVERTORIAL CASCADING SYSTEMS FOR COMMERCIAL ENVIRONMENTS The ideal means of achieving greater modulation and efficiencies is now recognised as the ability to spread heating loads across multiple energy sources, which can be achieved by cascading boilers. This provides a primary input to large buildings with high, but also fluctuating, demands. The benefit of a cascaded system with more than one boiler is that it gives the end client ultimate peace of mind by providing a reliable contingency plan; the heating function is upheld when maintenance is taking place on one of the connected appliances, avoiding significant downtime. Alpha’s ARES Tec offers an integrated Boiler Cascade Manager to ensure the load is spread evenly between heat modules. This optimises the changing demands on the boiler that are common among large commercial buildings 22 BUILDING PRODUCTS | APRIL 2017 and also provides a rapid warm up in response to multiple requests. Independently – if demand falls low enough – the boiler can run on the minimum output of a single module, minimising energy use. To ensure equal daily rotation and even running times, the boiler cascade manager alternates the ignition of the modules every 24 hours. A cascaded system benefits large and light commercial applications, larger buildings such as schools, hospitals, leisure centres and larger social housing developments where floor-standing boilers are required, Alpha recommends its ARES Tec boilers and accessories. This is also suitable for solar thermal interface, creating further energy efficiency options for the customer. For light commercial projects where there is less floor space available but output requirements are still high, the ProTec boilers can be fitted to walls or mounted in purpose made free standing frames to provide heating to retail and large luxury domestic properties or community buildings. Committed to flexibility, the full commercial range can be supplied for use with natural or propane gas (LPG) and are capable of being installed as a single unit or in simple modular formations for even bigger outputs. However, even if a single unit could fulfil needs, it is more efficient to spread the load across multiple boilers and it is therefore important to choose a manufacturer that can assess and recommend an energy efficient system suitable to your output needs. This ability to adapt the range to a number of applications makes it a popular choice for housing associations, as the boilers can also be utilised to serve district heating or heat interface units for small or larger developments. SPECIFIERS’ GUIDE Businesses have a duty to ensure carbon emissions are kept to a minimum, and with heating and hot water accounting for over 60% of energy bills the pressure is also on specifiers to find a solution that reduces running costs. Alpha Heating Innovation has therefore created a comprehensive range of commercial boilers to suit any building or development.
