Indirect Water Heaters

The indirect heating system is a proven method of providing large volumes of hot water for a variety of applications. Our years of experience in this field have perfected the Bryan Indirect Water Heater. You’ll find application information, specifications and general information in this brochure. 


Simplicity of indirect heating
The indirect heat exchanger method of heating water is extremely simple. The primary water in the heater is maintained at a constant temperature and recirculated only within the heating vessel. The heat exchanger, placed in the primary water, absorbs heat and transfers it to the water flowing through its copper tubes.

Efficiency in a compact unit
The result of the simple design is an efficient heating method that requires very little floor space. Bryan Indirect Water Heaters require less floor space than most other types of heaters or boilers. They are shipped completely assembled and wired.

Efficient “Flexible Water Tube” design
Bryan Indirect Water Heaters incorporate the Bryan bent water tube that provides rapid internal water circulation. The result is maximum heat transfer, and the flexible tubes eliminate the chance of thermal shock. All tubes are easily removable and replaceable without welding or rolling.

Economical operation
Since service or process water does not come into contact with high temperature heating surfaces, there is little danger of scale or corrosion. Maintenance and replacement costs are greatly reduced, and the unit provides a long, efficient service life.

Engineered for automatic operation 

The primary water in the heating vessel is continuously, automatically recirculated. And it rarely requires changing.

Choice of systems to meet specific needs 

Storage tank system. When large volumes, but intermittent draws, are required, a storage tank is used. Circulation between the tank and heat exchanger maintains the required temperature in the tank. 

Tankless system. When the hot water draw is relatively constant over long periods, the tank may be eliminated. This system should be considered whenever possible.

Tank-Tankless system. When two temperatures of water are required, a tank type system may be used to supply water at one temperature while water from the tank is recirculated through the heat exchanger to pro-vide the second, higher temperature water.
