I live in Upstate NY and in the winter it gets below 0° F.
I currently have baseboard water heating throughout my home. Prior to this I believe there was a gravity furnace which supplied the house with heat.
I am hoping to switch to a regular furnace for two main reasons:
- I would really like to get central A/C in the future
- I strongly dislike the idea of water lines everywhere in my house; copper does fail eventually
Right now we have 2 zones, upstairs and downstairs, which would be nice to maintain.
My 1940 home has a full basement and a full attic in which I can stand upright.
I would like to have a basement furnace which heats the downstairs. It will be trivial to run the supply lines and cold returns in the walls above the baseboard trim. This would allow me to remove the downstairs zone from my boiler.
I would also like to have an attic furnace to heat the upstairs. I feel that this would be easier than trying to run HVAC upstairs from the basement and it would make dual-zones easier to achieve. I think the supply lines would be do-able but properly doing the cold air returns would be a headache.
My understanding is that a high efficiency furnace has a condensate reservoir which gets pumped out through a 1/4 tube whenever it fills up; much like a dehumidifier with a built-in pump. Would this be a freezing risk? My attic does get below freezing.
Assuming I have insulated supply runs, would my attic get heated by the furnace and cause ice dams on my roof?
I do have some space on the second floor which can fit a furnace, would this be a better choice?
