Thermal Oil
Thermal oil offers the user the capability of high-temperature operation (up to 600F with organic thermal oils and 800F with certain synthetics) at very low pressures. Due to the low operating pressure and properties of thermal oil, most heaters are built to ASME Section VIII, and a licensed boiler operator is not typically required.

Many people around the world refer to these systems by different names. The phrases thermal oil heater, thermal oil system, thermal oil boiler, thermal fluid heater, thermal fluid system, thermal oil boiler, hot oil heater, hot oil system, and hot oil boiler generally all refer to the same type of closed-loop liquid phase heat transfer system. Note that many people use the terms thermal oil boiler or thermal fluid boiler even though most systems do not involve any type of vaporization.

Hot Water & Water-Glycol
Due to its superior thermophysical properties, water is an ideal heat transfer medium. Closed loop liquid phase hot water or glycol solution systems are an excellent choice for indirect process heating up to approximately 300F. Because the water is used in a closed loop with no direct feed water source, heaters are typically built to ASME Section VIII and do not require a licensed boiler operator. Heaters can be built to ASME Section I when required.
