Paul Hawkins looks at how the latest modular commercial boiler systems can provide a flexible, space-saving solution without compromising output.
At Vokèra by Riello we believe the concept of system flexibility holds the key to meeting the diverse needs of the commercial sector. Indeed, we know from our extensive experience of working with specifiers and installers in this demanding market that the challenges and permutations they encounter are virtually endless.
Flexibility in action
An example of this flexibility in action can be seen in the recent installation of a Riello Steel Pro Power modular floor standing gas condensing system in Glasgow. Local heating specialists, ACR Contractors, won the contract to find a new system for a leading restaurant chain in the Scottish city. Given that the existing boiler was a Vokèra appliance that had come to the end of its economic life, ACR looked to Vokèra for a high efficiency replacement that could also overcome the project’s siting challenge. As well as matching the busy restaurant’s heating and hot water demands, the new boiler had to be installed on the flat roof of the multi-storey building as no internal plant room space was available.
A standalone 230kW Steel Pro Power from Vokèra by Riello’s commercial boiler range, supplied with auxiliary accessories for outdoor installation, provided the perfect solution. This modular floor standing gas condensing system was conceived and developed by Riello with the aim of maximising flexibility and simplicity of installation. The system is capable of achieving high energy efficiency values, whilst minimising the space occupied, and the design is based on the principles of modularity to facilitate ease of installation and handling operations.
Minimising cost and disruption
Ready for simple and quick installation, the Steel Pro Power consists of pre-built technical cabinets comprising an assembled frame in anodised aluminium and painted panels. On the Glasgow project, ACR was able to partially dismantle the cabinets into smaller sections that could be carried up stairwells and onto the roof without the need for a crane – saving this additional cost and minimising disruption for the restaurant. Once in position, reassembling the cabinets was quick and easy and the installation was completed by a two-man team in around three days.
Steel Pro Power systems can be installed either in single configuration (from 114 up to 540kW) as specified for the Glasgow restaurant, or in cascade (from 655 up to 1310kW). The power supplied by the individual modules is managed with the new electronics control, compatible with the Modbus protocol. Advanced operating logic ensures optimal management, as well as allowing the distribution of heat in a precise manner to the various circuits. Remote management is also available via Modbus.
Technical support
Steel Pro Power cabinets contain 2, 3 or 4 heat engines (depending on the model) with low-energy modulating pumps. All models in the range are internally equipped with hydraulic, gas, condensate and flue exhaust manifolds. Compactness, versatility and electronic management, coupled to the new patented double-acting stainless steel heat exchanger and the premixed burner with wide modulation range, make Steel Pro Power an extremely efficient and low emissions (NOx Class 6) system for a variety of commercial applications.
According to Alan Ross, proprietor of ACR Contractors, the technical support provided by Vokèra by Riello’s team for the Glasgow restaurant project was invaluable, including on-site visits, and based on the success of this installation he has no hesitation in recommending Vokèra by Riello for future projects.
