VOKÈRA Condensing Boilers Provide Upgrade to Best Western Hotel

Space-saving design, system flexibility and advanced electronic control make Vokèra by Riello’s all-new Condexa Pro condensing boilers an ideal solution for a luxury hotel in Sheffield. The Best Western Plus Kenwood Hall has replaced six outdated boilers serving hotel rooms, kitchen, restaurant and public areas with three compact Condexa Pro 90 units. Vokèra, through its parent company Riello Group, is a part of Carrier, a leading global provider of innovative heating, ventilating and air conditioning (HVAC), refrigeration, fire, security and building automation technologies.

The new boilers are installed in a linear cascade configuration on a precision-engineered framework, purpose-designed to assist installation and allow easy access to all components from the front. In addition, logic integrated in the electronic control allows each boiler to operate either as a primary or a secondary in the cascade, ensuring constant operation, even while being serviced.

The Condexa Pro units replaced boilers that had become increasingly unreliable and inefficient. Sim Cowen, Managing Director, B P Dempsey Ltd, the local commercial heating specialists, recommended replacing them with Condexa Pro units.

“Cowen recommended Vokèra by Riello and his advice was spot on,” said Gary Dodd, Maintenance Manager at Kenwood Hall. “Our new Condexa Pro 90 boilers haven’t missed a beat since they were commissioned. In fact, they will probably be our preferred choice when the time comes to replace the remaining existing boilers at Kenwood Hall – and possibly across the group’s other hotels in the area,” he added.

Vokèra’s sales and technical team provided a comprehensive support package for the project, including a pre-sales report showing the proposed Condexa Pro 90 cascade configuration and how this would fit into the confined plant room space. Vokèra was also able to handle the requirement for an extended external flue to clear the roof of the hotel, which saved the cost of a specialist flue contractor.

“Kenwood Hall was my first Vokèra by Riello project but I’m sure it won’t be my last,” Cowen said. “The new Condexa Pro offers excellent value for money and it is designed to adapt to the most varied plant requirements. It’s also very compact and powerful, which meant that we were able to replace six old boilers with just three 90kW Condexa Pro which are more than able to meet the hotel’s heating needs in terms of output and efficiency.”

Vokèra by Riello’s new range of Condexa Pro wall-hung condensing boilers extend from 35 up to 131kW and offer solutions for new plants, replacements or renovations of old heating systems. Each versatile appliance forms the principle element in a system with almost limitless configurations, from simple standalone solutions to modular cascade systems, as at Kenwood Hall, that can accommodate specific requirements thanks to the wide range of accessories.

Among the most innovative components of the new Condexa Pro is an optimised stainless steel heat exchanger, designed and manufactured by Riello, with single or double coil patented sections and premix burners for high turndown ratio and low emissions. In addition, the calculation speed and advanced management algorithms of the electronic control system allow regulated ambient temperatures and the best possible operation performance both for standalone boilers and for multiple cascades up to 10 units.
