Have you ever lived in a home with the old-fashion boiler/radiator heat? Is it less dry that gas furnace heat
My home has a boiler with radiant heat, my previous home had forced hot air with a gas furnace. I find that the boiler is a more even heat and doesn't dry the house out. We also don't have as much trouble with static electricity. Forced hot air dries out the air while heating it, that is why you need a humidifier.
It is less dry than a gas furnace heat, but it seems like it takes longer to heat the house, too.
