Stokvis boilers selected for Walsall schools summer upgrade

The summer holiday period presented the ideal opportunity for the installation of three Stokvis Evolution boilers at a school in Walsall last August.

Queen Mary’s High School provides places for over 750 pupils within buildings that can be hard to heat.

Stokvis Energy Systems initially became involved when Solihull based Stewart Associates began the heating services design work early in the year, preparing for the replacement of the old cast iron boilers.

Lord Combustion was subsequently awarded the contract to install a trio of R602 Evolution boilers within the school’s plant room.

The upgrade to the heating system not only betters energy performance and reduces future maintenance requirements, but also features one of the manufacturer’s GCD044 BARE plate heat exchangers to provide separation from the very old existing heating circuits.

MD of Lord Combustion, Stuart Smith, commented on the contract: “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.”

The senior consultant on the project for Stewarts, Peter Drew, added: “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.”

The R600 EVOLUTION range features seven models, offering outputs from 142 to 540kW, while combining high economy with compact dimensions, making them the ‘go anywhere’ solution for confined spaces in either retrofit or less accessible new-build applications.

Also, the new high efficiency boilers are all designed to pass through standard doorways. For those sites with even tighter access, the boilers are simply dismantled and reassembled in position on site.

Furthermore, they are low in weigh; between 290 and 595Kg when empty, and can prove ideal for tall buildings as they provide 8 Bar maximum pressure.
