The main determinant of the thermal fluid heater's price is the thermal power of the heater. In general, the price of the 0.7MW will be lower than the 1.4MW (the same fuel, the same devices). The price of various thermal fluid heater manufacturers generally follows this rule.

　　Select an appropriate heater in different manufactures, it mainly depends on the workmanship of the product and the details of the various components. Although the whole heater looks the same, the different treatment of the details directly affects the operation of the heater in future, such as: how to deal with the high temperature of the burner and the boiler contact parts; how to solve the problems of biomass heat-conducting oil boiler burning door and coking. If these details can be dealt with in place, although the price of the boiler will increase, the operating costs of the boiler will be greatly reduced in the future.

　　The flue gas system of the heat-conducting oil boiler also need to be considered. Which directly determines the treatment of the high-temperature flue gas at the tail of the thermal fluid heater. The price gap of different flue gas systems is also relatively large.

　　Users of thermal fluid heater need to pay attention to the time of boiling oil (also called boiling out ) after the hydrostatic test, if there is no water discharged from the hydrostatic test before delivery. Although the cost will be higher, it is much lower than the cost of boiling oil. (Zozen Boiler’s boiling oil time is 2 days, and the peer’s time is 12 days.)
