Heat vents near ceiling
Hi, I have a house built in 1863. When we bought the house the furnace was circa 1932. The heat vents out near the ceiling instead of the floor in all the rooms. I know heat rises and cold air sinks but I am wondering why they did this and if there is any advantage to it.

As I go about my work I have been cutting the vents off at the floor, but I am thinking that if we ever get central air it may be good to have some high vents.

What do you all think?

Yes, we have replaced the furnace, but the old ones still worked. They just were not very efficient.

in renovations even to an 1860's abode... duct placement is often a trade off with accessibility. if u r asking for optimum duct layout then post a drawing and details. it's your comfort... think air flow and what you want to accomplish.

An HVAC consultant or designer will be able to create the ultimate layout and distribution duct system for you. A heat loss calculation will determine exactly how much air at what temperature is required for each room. These numbers will also determine the appropriate duct sizing.You cant just wing it and expect an effecient operation.
HVAC design has changed a lot since the '30s and gravity fed furnaces.
