Our client, a nationwide Facilities Management company, approached Rapid Energy to facilitate a temporary solution for heating and hot water services for one of their Leisure Centres in Kent. Due to the UK Government announcing the reopening of gyms and leisure centres on the 12th April, timing and response times was critical. Our client, who had already used Rapid Energy for a previous project, required a solution to ensure their leisure centre was reopened to the public on schedule.

The client’s existing boilers had failed. And with a 4 week delay on the parts, a temporary solution was the only option to supply LTHW into the primary heating circuit. Our client’s requirement included the heating of 2 large swimming pools and 3 x 1000L calorifiers to supply hot water to the showers within the facility. 

Following the initial call, Rapid Energy arranged a site survey with the client and arrived onsite within 2 hours. One of our consultants attended the site to further understand the client’s requirements and to propose a suitable temporary boiler solution.

2000kW LTHW Packaged Boiler

2000kW (2MW) Temporary Boiler Solution

  • 1 x 1.3MW temporary plant room
  • 1 x 600kW temporary plant room
  • 1 x 4500L bunded fuel tank 
  • 1 x 3000L bunded fuel tank
  • 40m of 4 inch pipework
  • 2 x 25m lead – Three Phase 32A
  • 2 x 4 inch camlock to PN16 flange adaptors


Whilst onsite, our team examined the existing plant room which consisted of 3 x 600kW boilers. After almost 12 months of being idle, all 3 boilers experienced major faults.

All 3 boilers connected into a header, which in turn supplied the air handling units (AHU) and the swimming pools. The hot water was supplied by 3 x 1000L calorifiers, fed by the primary circuit. With the leisure centre just days away from reopening, the swimming pool temperatures had to be increased from 5 degrees to 28+ degrees in order to allow the swimmers to comfortably use the pools.

Installation and location

Temporary Boiler Solution

Our solution was to supply a 1 x 1.3MW packaged boiler (duty) and 1 x 600kW boiler. We could then connect into the main header supplying LTHW at 90 degrees initially, to get some much needed heat back into the building and swimming pools.

Following the client’s instruction, our equipment and engineers were deployed and the boilers were landed onsite within 12hrs from the completed survey. Our engineers then connected a total of 40m of  4 inch temporary hose into the client’s existing isolation valves that were in place on the flow/return pipework within the building.

We provided 2 x 25m, three phase 32 amp leads which were connected into commando sockets supplied by the onsite electrician. This was to power our BMS system and the twin pump sets within both our temporary boiler plant rooms. The two fuel tanks were then linked into the burners with fuel lines, and the engineers began the commissioning process.

Following commissioning, the team back at Rapid Energy’s HQ confirmed the temperature set points via the BMS and signed off the installation as complete. Once the required temperatures were reached within the building and pools, we placed the 600kW boiler into standby mode. This was to reduce the fuel consumption, saving our client running costs, whilst the repair works to their existing plant room were being carried out.

Customer Quote

“With the Leisure Centre facing additional closure and subsequent financial loss, it was imperative we delivered a fast and efficient solution to our client’s facility. This is another great example of how quick, methodical and efficient our team is whilst working under pressure. We delivered great customer service and operational excellence to ensure the Leisure Centre could once again open their doors to the public”
