I am switching over my oil fired hot water boiler to propane come spring. Current set up is 2 zones; one thermostat is serving 24 cast iron rads on three floors. the other zone is the boiler running pipes to an air handler and pushing out forced air in kitchen/breakfast room.
The rads break out to 9 on first floor, 11 on second, 4 on third. I'm considering putting the first floor on its own zone and the 2nd/3rd floor on its own zone with a thermostat on 2nd flr.
I've had some contractors look at it and it is possible. They would need to run a new pipe off the boiler and tap into the 9 rads. They suggested just doing the supply side and leaving the return pipes on the same return. all the pipes are accessible in open basement ceiling but I'm sure it's still a fair amount of labor to untie these and pipe the new main.
It will all be determined by the estimate $$, but is it wise to do this for the long haul? Meaning, can you expect a fair amount of fuel savings by separating the floors into zones?
The other annoyance is we have a wood burning fireplace in the room where the thermostat is located. The living room heats up quite a bit and then the rest of the house gets cold.
