We’re excited to introduce the Rapid Energy 450kW Slimline Gas Packaged Boiler – a compact, high-performance temporary heating solution designed for projects and industries where space, speed, and reliability really matter.
Whether you’re working in construction, facilities management, manufacturing, healthcare, education, utilities, commercial property, or anywhere a dependable temporary boiler is essential, this slimline boiler delivers big output with a remarkably small footprint.
Why We Developed the 450kW Slimline Boiler
Throughout different projects, we regularly see the need for a temporary boiler option that can:
- Fit into tight plant rooms and restricted areas
- Deploy quickly during planned works or emergencies
- Support commissioning, upgrades, refurbishments, and seasonal heating demand
- Provide strong performance with minimal electrical requirements and low carbon emissions
The 450kW slimline boiler does exactly that. Engineered for fast integration and easy movement on constrained sites, it offers powerful heating without the bulk traditionally associated with high-capacity boilers.
Engineered Performance Across Industries
Key features include:
- 450kW output delivered through 3 x 150kW condensing modules
- Ultra-low NOx gas burner
- Low electrical demand: running current of just 8.4A
- 230V 16A power supply (BS4343 3-pin)
- Low noise levels: 51 dBA at 1m / 40 dBA at 10m
- Pump performance: 6.8 L/s @ 7.5m head
- DN65 gas connection
- 3” camlock flow/return connections
Compact Design for Easy Deployment
Despite its 450kW output, the unit’s footprint is just:
2010mm (L) x 820mm (W) x 2000mm (H)
This slimline layout allows:
- Access through standard doorways
- Placement in basements, corridors, and limited-access plant rooms
- Flexible positioning around busy construction sites
- Minimal disruption during installation or removal
Whether it’s hired for a commercial building, rented for industrial operations, or used to support critical infrastructure, the compact design removes many of the logistical headaches associated with temporary boilers.
Ultra-Low NOx for Cleaner Operation
With its ultra-low NOx burner, the slimline is well-suited to sites where emissions must be carefully managed, including urban areas, sensitive environments, and sustainability-led projects.
Clean combustion helps organisations:
- Reduce local air pollution during temporary works
- Hit environmental targets
- Support ESG reporting
- Prepare for tightening efficiency and emission standards
