Condexa Pro 500 Box, a pre-built floor-standing cabinet commercial boiler from Vokèra by Riello has provided a plug and play heating solution for a prestigious independent preparatory school in Berkshire. The fully modulating gas condensing boiler replaces an outdated oil-fired boiler and oil storage tank at the school and is installed externally, freeing up valuable internal space. 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.

With indoor space at a premium, the ability to install the Condexa Pro 500 Box boiler outside was a key benefit for the school, as was the compact footprint. The self-contained units are supplied with water and gas manifolds, flue exhaust duct and condensate evacuation line already fitted and connected. A water drain for each heating unit is also built in as standard. When required, an internal solution is also available.

In addition to its space-saving design, the Condexa Pro Box boiler offers exceptional efficiency versus return water temperature. Units incorporate a highly efficient heat engine, resulting in an extremely low return temperature/flue exhaust gas temperature (temperature differential). To assist specification, Vokèra’s technical team is able to calculate how much clients could save on their annual energy consumption by installing a Condexa Pro Box, based on their existing fuel tariffs. The boiler’s impressive energy efficiency is complemented by minimum polluting emissions due to the controlled pre-mix burner and micro-flame burner combination.

The Condexa Pro 500 Box boiler specified for the replacement project at the school features four heat exchangers in cascade configuration, offering 200kW total output. The innovative design enables easy access to all components from the front, and each combustion unit can be individually serviced and maintained without loss of other units, ensuring uninterrupted operation.

Condexa Pro Box fully modulating condensing boilers also boast the latest generation electronic control. Although the compact in-line solution installed at the Berkshire school is connected to an existing Building Management System (BMS), the boiler’s sophisticated heating control and monitoring may negate the need for a BMS in some applications. The advanced remote control facility allows a maximum distance of 100 meters and makes it possible for end-users to manage functions such as setting the boiler’s on and off timings and weekly programming of the circuit.
