An M&E client required a packaged boiler solution that would provide temporary heat on a 50+ bed hotel renovation project in Buckinghamshire. The client had experienced multiple failures within their existing plant room, which caused considerable delays to their project. The client needed consistent, reliable heat into the building to increase the internal temperatures, which in turn would support their drying process.
It was quickly established that the client required a site survey from Rapid Energy in order to establish the best solution for restoring heat to their building.
Rapid Energy’s team arrived on site to conduct a scope of works and to determine the appropriate temporary boiler solution.
The client’s existing boiler plant room was located in the basement and consisted of 3 x 100kW biomass boilers which fed into a plate heat exchanger on the primary circuit. We established that the best point of connection would be to disconnect and isolate the existing biomass from the plate heat exchanger which feeds the primary circuit. We could then connect our temporary packaged boiler directly onto the heat exchanger. This allowed us to connect into the system quickly, negating the need to drain the whole system down and refilling.
Another consideration was the location of the packaged boiler. This was a large scale renovation project and as such, scaffolding was erected around the building with a number of workers onsite. It was recommended to keep the packaged boiler away from the building to allow for sufficient room for outside works to the building.
The closest landing location for the packaged boiler was 60 metres away, and on a different floor from the permanent plant room, which was located in the basement. Because we were connecting into the primary heating circuit, 120 metres of high pressure hose was specified for the flow and returns. The hose run was confirmed with both our client and the site manager, to ensure it was kept out of the way of all the different contractors onsite.
Upon instruction from the client, equipment was ring-fenced and loaded onto the HIAB. A fuel delivery was arranged and our team of engineers mobilised. Once our engineers arrived onsite they proceeded to isolate the permanent system utilising the existing isolation valves on the primary circuit. Our team then installed DN65 to DN50 reducers on the plate heat exchanger, allowing us to connect our temporary flow and return pipework.
Once the connection points were installed, our 2 man team proceeded to lay out a total of 120 metres of heating hose. This included a route dropping down from ground level into the basement. Once both sets of flow and returns were connected to the temporary boiler, the engineers provided a 50m single phase lead, connecting the power from the plant room to the temporary boiler. We then began the commissioning process by filling and pressurising the packaged boiler to a 2 bar pressure set point. Once completed, the engineers commissioned both boilers which included a call to Rapid Energy’s HQ to confirm visuals on the BMS.
From the moment we were instructed, we delivered, installed and commissioned a temporary 300kw heating solution allowing the project to get back on track and supplying much needed heat into the building.
