Pump and water tank booster heater
I am a former civilian CFR FF for the WiANG and we had a a crash truck with a booster heater that was designed to keep the pump, piping, gauges, AND the water tank from freezing. It was a diesel fuel heater that ran off from the main diesel fuel tank for the engine. What sent me back to thinking about this was a training burn we did on December 7th, it was down in the single digits and 2 pumpers froze up and it was a real hassle to thaw them out.
Most of the current pump compartment heaters simply do not supply enough heat and they are primarily designed to keep the gauges from freezing. I began to think about adding a booster heater and having the pump panel inside a roll up door to keep it warm until arriving on scene.
Anybody done anything like this? Or even seen one on a structural engine?
