HWP Series:
Self-Contained Water Heating Systems

The HWP Series combines the rugged Sioux water heating/pumping system combination of the M Series with a 1,000 gallon atmospherically-vented water tank. The unit has multiple pumps: one for each million BTU section to circulate water through the heater, and one to discharge water. Tank includes automatic float level valve, liquid level sight gauge, adjustable tank temperature control with immersion well, thermometer, ladder, inspection port, and motorized draft diverter/damper. The entire system is mounted on a rugged steel skid for portability.
