Line D ICI Appliances Flashcards
What advantage does a direct contact water heater have?
No loss out the stack, no lost condensation, no lost radiant heat.
Describe how an immersion burner works.
A submerged radiant tube heat exchanger is used to heat large volumes of liquid.
Describe how an indirect bath heater works.
It uses two separate, submerged heat exchangers to heat a fluid with one heat exchanger and transfer that heat from the fluid to the second heat exchanger.
What are three of the potential hazards of using a direct fired construction heater?
- Being too close to combustibles can lead to a fire
- The possibility of fire if used in a wood frame structure
- There is the potential for dangerous levels of carbon monoxide
