Options
The most popular options for thermal fluid heaters are expansion tanks, pump packages, economizers and combustion air preheaters.

The expansion tank is usually mounted as a separate unit and sometimes includes the circulating pump package. The package may include strainers, valves, gauges and other items as may be needed.

The economizer recovers heat from the exhaust stack and transfers it to the thermal fluid for increased efficiency.

The combustion air preheater recovers heat from the exhaust stack and preheats burner inlet air for increased heater efficiency.

The thermal fluid heater shown below has extraordinary features. Features that increase performance. Features that increase its life. Features that reduce maintenance.

It's extraordinary convection section with finned tubing increases thermal efficiency 3%. Actually, convection sections can be designed to increase thermal efficiency up to 8%, depending mainly on operating temperatures.

And there are numerous other extradrdinary features. See the photo below to learn what they are and what they do. These are no-frill features that you will want to consider on your next heater. Each one provides a benefit to justify its cost. Pick those appropriate for your application and decide its value to you.
