Shorter ducts are generally associated with better heating performance and efficiency.
Is it better to have floor or ceiling vents.
Unlike ceiling registers high wall registers don t blow air directly down on you.
Either type of register ceiling or floor can be used for this as long as the need for the area or room is matched.
Instead the air they deliver flows across the upper part of the room and mixes with the room air.
The opposite is true for ceiling ducts which should be placed as far away from windows as possible so that heat warms the room and not the window.
It may not be possible to install them in the floor or the additional work required may make it cost prohibitive.
As this air moves it draws room air up toward it which improves air circulation even more.
As for pros and cons of either.
The placement of your return is.
For heating vents in the floor would be better.
If theyre in the floor youll want your return in the ceiling.
As with ceiling registers wall registers give you more free floor space.
Supply registers are the vents that deliver warm or cool air from your central heating cooling system to each room.
Heat vents are better in the floor if possible.
The same approach is best for vents that return air to the system with floor collection vents for heating systems to return cool air and high wall collection vents for air conditioning systems to capture hot air.
Vents in the ceiling will work.
Floor vents on the other hand favor heating of the house.
It almost falls right in place into a blue print of a house.
If the registers are in the ceiling you will want your return low.
What is the difference between supply registers and return registers.
Does it really make that much difference and what would you recommend.
Since hot air rises it is more appropriate for floor vents.
I have lived in an older house that had floor vents and the heating was terrific.
This isnt the main concern however.
The reason why many homes have ceiling vents is because it is cheaper and easier to install when the house is being built.
For cooling ceiling would be better.
It is also possible to use low wall vents for a heating system.
The warm air will offset any cold air entering around the window and reduce condensation or frost on the window.
Spans of ductwork from a basement furnace to floor ducts are more direct and shorter versus ceiling ducts.
