🔍 Key Concepts

• How convection works: warm air rises, cool air sinks • Typical location of convectors in a cabin to heat the occupied space efficiently • Direction of air flow through a radiator/convector housing (where is the cool air intake vs. warm air outlet)

💭 Think About

• Which option correctly uses the idea that cool air should enter low and warm air should leave high, based on natural convection? • If you want to warm people standing or sitting on the deck, would you mount the heater near the deck or near the overhead? • Look carefully at which answers put the intake and outlet in the right vertical order, then which of those puts the unit in the most effective place on the bulkhead.

✅ Before You Answer

• Confirm that cool air intake is placed where cooler (heavier) air naturally collects • Confirm that warm air outlet is placed where rising warm air can circulate into the room • Verify the mounting height that best heats the space people actually occupy (near the deck vs. near the overhead)
