I'm totally ignorant about this, and so would appreciate any information or sites that I could go to to get more information. In our 1920's home in VA we currently have a gravity radiator heating system and a two zone lennox a/c. Both need to be replaced (the boiler is original and is operating pretty inefficiently to say the least). Someone suggested combining the two systems into one and installing a heat pump for the heat and simply use the existing a.c. ducts to deliver the heat and ac, and essentially shutting off the radiator system.
I had always heard that radiator heat is among the best. But now I'm wondering if I should move into the 21st century and go with something like a carrier infinity system with a humidifer. Or simply keep with the two separate systems.
Any thoughts, philosophical or practical would be very appreciated. I'm willing to be educated.
