Stokvis EVOLUTION R600 boilers
During the summer hoildays, Stokvis EVOLUTION R600 boilers were installed at Queen Mary High School in Walsall. The school is used by more than 750 pupils and staff, and its buildings were often difficult to heat. A heating refurbishment project was initiated to replace the school's old cast iron boilers, with design work undertaken by Stewart Associates and installation work contracted to Lord Combustion Services.
Stokvis Energy Systems manufactured and supplied three of its EVOLUTION R600 gas-fired condensing boilers for the project, with installation completed in August 2017.
The new boilers provided improved energy performance and reduced future maintenance requirements. They feature GCD044 BARE plate heat exchangers to provide separation from the very old existing heating circuits.
The R600 EVOLUTION range has seven models with outputs ranging from 14-540kW.
All have compact dimensions to allow them to be easily retrofitted or installed in new-build projects with limited space. Their maximum 8 bar pressure makes them particularly suitable for tall buildings, and they are also low in weight - between 290 and 595kg when empty.
Stuart Smith, MD of Lord Combustion, said: "We have used Stokvis equipment on a number of projects in the past and always found it to be very reliable. In the case of the Queen Mary High School in Walsall, switching the old cast iron boilers saves a lot of space in the plant room and represents a major upgrade in terms of performance. In addition, fitting the bare plate heat exchanger as a separation plate will prevent the higher pressure of the system causing issues within the original LTHW pipework or radiators around the school. Stokvis carried out the commissioning work after we completed the installation and the whole job went really well.”
Peter Drew, the senior consultant from Stewart Associates, said: “Because of the age of the system and the condition of the pipe we were connecting to, we wanted to create a hydraulic separation – keeping the primary circuit and the secondary side completely separate. The Stokvis boilers just worked well in this context while they could also supply the bare plate heat exchanger - to give us a complete package from one manufacturer.”
