We received a call at 3pm on Thursday afternoon from a London client. Their energy centre had failed, leaving over 320 apartments without heating or hot water. During the call it was quickly established that the client required a survey to determine the best solution to restore critical services back to their facility.
Within 1 hour, Rapid Energy’s team arrived on site to conduct a scope of required work to determine the appropriate hire solution.
The client’s energy centre contained 4 no 250kW heating boilers. It also contained 2 no 500kW direct fired hot water heaters which fed two large calorifiers. The first challenge was to identify the best place to isolate and connect into both of the circuits.
The closest landing location for each temporary boiler was over 100 metres away. The location was also on a different floor/level from the underground plant room, which was located in the basement.
We were on a very tight deadline and with residents’ concerns growing, our primary objective was to ensure the heating and hot water was restored within 24 hours.
Our solution was to supply a 1.3MW packaged boiler, connecting into the primary circuit. In addition, we also supplied a 600kW packaged boiler feeding 2 x 250kW heat exchangers. The 600kW packaged boiler ensured that hot water was supplied to the incumbent calorifiers.
We identified locations on both the primary pipework and secondary pipework that would allow us to bypass the failed boilers and water heaters.
Upon instruction from the client, equipment was immediately loaded onto the HIABs and our team of engineers mobilised. Within 16 hours all the necessary equipment was delivered and landed onsite. Our engineers then isolated the permanent system utilising the existing isolation valves on the different primary circuits. Our 3 man team laid out a total of 200 metres of hose. This included a route through the residents car park which had to be fenced off to comply with health and safety. As always, the health and safety of our engineers, operatives and residents onsite was paramount.
Once both sets of flow and returns were connected to the temporary boilers, we then began the commissioning process by filling and venting each temporary boiler to the working pressure of the existing system. Once the packaged boilers were fully filled and vented we then gently integrated both systems together. Upon completion, the engineers commissioned both boilers and heat exchangers which included a call to Rapid Energy’s HQ to confirm visuals on the BMS. Before leaving the site the engineers installed heras fencing around the whole compound to ensure the safety of the public was maintained and to secure the equipment.
From the moment we were instructed, we delivered, installed and commissioned a temporary heating solution within 24 hours. Resulting in happy residents and the concierge’s phone subsequently stopped ringing.
