QuikWater MultiTower

50% to 100% Backup; Increased Turndown

QuikWater's MultiTower direct-contact water heating system is an optional configuration of our original Flagship system.

The MultiTower is ideal for concrete production, commercial laundries, and the glass, textiles, car washing, food processing, government, and aviation industries, producing 9 to 2,300 gallons per minute of pure, potable, hot water.

All QuikWater systems are engineered with our innovative clean-burn combustion technology – a dry fire process that is not only safer than conventional boilers but operates with 99% energy efficiency. We also manufacture our systems using the highest quality materials for extra long life and extra low maintenance.

QuikWater systems are the first direct-contact water heating systems to be certified by the NSF/ANSI Standard 3A and 5 for food processing applications.

Quikwater Heater Capacities

Heater calculations:

BTU Required = Temp Rise x GPM x 500

Temp Rise = Hot Water Temp – Cold Water Temp

(If temperature rise is less than 50, please consult the factory)


Heater capacities reduced for elevations above 1000 feet.
Reduction formula for maximum BTU outputs:
BTU reduction percentage = Elevation – 1000 ÷ 1000 x 4%
