How can i switch my register vents from old gravity furnace style to a new furnace style?
Question:My home was built in the early 1900's and has a gravty furnace. I am going to be getting it replaced with a new energy efficient furnace, but the register vents remain. I have seen some websites that you can purchase them from, but they cost the upwards of $50.00 a piece, and I will need at least 5 of them. I wasn't sure if you could frame them in and put one of the more common vent cover styles in? Thanks!!
Answers:
The heating/air-condition company doing the installation should be taking care of this - check to see what is included. It does not seem reasonable that they would just be installing the heating unit without making sure it is a complete working system.
I'm not quite sure about your requirements? A register is where the heat comes out. A grill is where cold air is returned to the furnace for re-heating.
Gravity furnaces required much bigger return air grills than are required by modern forced-air furnaces. So the number of your cold-air grills could probably be substantially reduced, in size and number, and modernized by the installation of new grills.
The heating registers of gravity furnaces are also oversized. Reflooring, etc., is usually so expensive that they are used as is and the pipes from the furnace to each register are made smaller.
Your heating/cooling contractor can fix you up with whatever you require but, of course, the cost of the job will go up accordingly.
Good luck.
you should leave it alone and let the guys installing your new unit do that's part of there job.
