Stokvis R600 EVOLUTION range boilers selected for Walsall schools summer upgrade

Queen Mary’s High School, Walsall, now benefits from new Stokvis Evolution boilers

The summer holiday period presents an ideal window for M&E companies to carry out critical maintenance and replacement work within education premises, with West Midlands based Lord Combustion Services completing the installation of three Stokvis Evolution boilers at a school in Walsall last August.

Queen Mary’s High School is on Upper Forster Street and provides places for over 750 pupils, within buildings which 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, ready for replacement of the old cast iron boilers.

Lord Combustion was subsequently awarded the contract to carry out the work and installed a trio of R602 Evolution boilers within the school’s plant room. The upgrade to the heating system not only improves 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.

The Managing Director of Lord Combustion, Stuart Smith, commented on the success of 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 confirmed: “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 includes 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.

In fact, the new high efficiency boilers are all designed to pass through standard doorways. For those sites with even tighter access the boilers are easily dismantled and reassembled in position on site. They are also low in weight – between 290 and 595Kg when empty – and can be ideal for tall buildings as they provide 8 Bar maximum pressure.
