We have natural gas at home and at work. My parents have an oil burning furnace which heats hot water which runs through baseboard heat. They finally - after 30 years - had to install a new furnace at the end of last year. I haven't heard any complaints or requests to visit us yet, so I'm assuming the new furnace is working.

In the motorhome we have a diesel burner which heats the water, then the hot water is run through a radiator type thing which has a little fan behind it to blow the air, which was heated by the water, out into the rooms. We also have electrically heated tile floors and I absolutley LOVE them!!! If I was ever going to redo our floors in the house and put tile in, I would definitely add the heated part to them. It is soooo neat to be able to walk around on an all tile floor with no slippers. We don't have to freeze our tootsies when we get out of bed in the middle of the night - but don't walk too near the edges, or near the door because you'll realize just how cold that floor would be if it wasn't heated!
