Floor Vents
Hi. I live in a three floor townhouse. The top floor has a Rinnai Gas Heater and the bottom two floors are electric. Not sure why they built it this way but they did. Anyway, I just bought a 40,000 BTU Gas Firplace for the bottom floor and want to cut floor vents into the rooms of the 2nd floor to let the heat rise up and eliminate the need for electric heat altogether. What is the best way to do this? Do I need to install some sort of metal duct work between the floors or can I just cut the openings and put decorative registers/grates over them? Bill
