Question

why it takes a long time to heat a room with a high ceiling

Answer 1

Rooms with high ceilings take a long time to heat up because the warm air that rises creates a space between the above and below warm air.

Heating a Room With High Ceiling

• When a person wants to heat up a high-ceiling space, they essentially heat the area starting from the ceiling point to downward.
• Thus, warmth takes a lot of time and energy to reach you and it takes much longer in offices with further high ceilings.
• Thus, radiant heating is the most effective way to heat up an area that has a high ceiling than using normal convection heaters.
