Indirect
Fully packaged storage water heater that utilizes double wall brazed plate heat exchanger to transfer heat. The design allows for multiple heat exchangers for redundancy, and recovery rates from 600 to 10,000 GPH. Tank sizes are 175 to 500 gallon standard, with up to 1000 gallon by special order.
Instantaneous
Instantaneous water heaters utilize plate/frame heat exchangers with a combination of sophisticated PID controllers and temperature valves to meet real-time load demands, producing up to 150GPM of hot water. Semi-instantaneous allows for either steam-to-water or water-to-water via tube type heat exchangers in a vertical or horizontal configuration, up to 225 GPM.
