Rapid Energy was approached by a large college in London amidst a major refurbishment, seeking a temporary heating solution that could seamlessly replace their existing system. The challenge was to provide 35 electric boilers to serve various air handling units (AHUs) spread across the extensive campus, all within limited available space.

3-36kW Electric Mobile Boiler

Product and Equipment Used

  • 35 x 36kW electric three phase boilers
  • 210m of 1” heating hose
  • 35 no three phase 63 amp 10m extension leads

Solution Implementation

To address this challenge, Rapid Energy proposed a site visit to tailor a suitable temporary boiler solution. After conducting a comprehensive survey, the proposed solution comprised of the following components:

The chosen solution involved deploying 35 units of 36kW electric boilers to efficiently supply heating to individual AHUs across the college campus. Installation required disconnecting existing pipework and seamlessly integrating the electric boilers into the flow/return pipework for swift connection. To facilitate this, the client coordinated the installation of 1” BSP connections and power supplies ahead of equipment delivery and installation.

Adaptability was key, considering some areas lacked the necessary three-phase 63 amp power supply. The selected boilers were versatile, featuring a plug-in system compatible with various power sources ranging from 3 to 36kW. Additional power leads were provided to ensure uninterrupted heating to AHUs without three-phase power capabilities.

The electric boilers’ manoeuvrability proved instrumental, enabling placement in diverse locations within the building to seamlessly connect with AHUs scattered across different areas and floors. Their electric nature eliminated the need for flues for waste gases, allowing for flexible positioning within the building structure. A team of two engineers efficiently relocated and connected the boilers to the respective AHU systems, ensuring smooth commissioning. Additionally, the boilers came equipped with integral pumps to facilitate circulation throughout the heating system.

Installation and location


The customer was delighted with the temporary installation which allowed some much needed breathing room whilst the heating upgrade works around the college took place.
