The Challenge

A mechanical contractor performing a steam boiler replacement at a medical center required a temporary solution to maintain hot water for hydronic heating during the project.

With the existing boiler system scheduled to be taken offline, the facility needed:

  • Continuous hot water supply during construction
  • A reliable temporary system capable of running 24/7
  • Minimal disruption to ongoing medical operations
  • A fast, coordinated installation aligned with the contractor’s schedule

The project required careful planning to ensure a seamless transition from the existing system to the temporary solution without impacting the facility.

The 1Source Solution

After a site walk with the contractor, 1Source Rentals engineered a temporary heating solution consisting of:

  • (1) 1,800,000 BTU HydroHeat Pro
  • (1) 25kVA Generator
  • (1) 500-Gallon Diesel Fuel Cell

This configuration provided a fully self-contained system capable of maintaining consistent hot water supply throughout the duration of the boiler replacement.

Installation Strategy & Execution

Pre-Installation (Day Prior to Startup)

The team mobilized equipment to the site and prepared the system for activation:

  • Positioned and leveled all equipment to ensure proper operation
  • Connected generator power to the HydroHeat Pro unit
  • Installed fuel lines between the heater and diesel fuel cell
  • Ran (1) 2” supply hose and (1) 2” return hose to the mechanical room
  • Suspended hoses overhead to keep pathways clear for contractor access

Startup & System Integration

On the day of startup, coordination with the mechanical contractor was critical:

  • Powered on the unit and primed fuel lines
  • Test-fired burners and preheated glycol prior to system switchover
  • Contractor isolated and drained the existing system
  • Hose manifolds were installed in the mechanical room
  • Final water connections were completed and hoses were filled and bled of air

Once the building system was ready:

  • Facility pumps were activated to establish flow through the heat exchanger
  • The HydroHeat Pro was set to the required temperature setpoint
  • Burners were engaged to maintain consistent output
  • System performance was monitored, including temperature and pressure readings

The Results

  • Successful installation with approximately 20 total labor hours across two technicians
  • Continuous 24/7 operation maintained for the full 3-week rental period
  • Seamless transition with little to no disruption to the medical center
  • Reliable hot water supply maintained throughout the boiler replacement

The Impact

Temporary heating in critical environments requires more than just equipment — it requires coordination, timing, and reliability.

Through detailed planning and close collaboration with the mechanical contractor, 1Source Rentals delivered a solution that ensured uninterrupted heating performance during a critical infrastructure upgrade.

When downtime isn’t an option, temporary systems play a vital role in keeping essential facilities operational.
