Your best bet is to use a seperate hot water boiler for your indirect ,radiant and baseboard loop then you won't haqve to ly oversize your steam boiler to handle all these other loads .I have personally seen alot of these type of systems installed and at best they did not perform to well there are alot of service issues the=at will come up over time and rember on a steam boiler using a loop off the boiler your gonna have to size the baseboard for a possible lower temp and use a good broze pump likea b&g series 100 and pipe a bypass and high limit other wise you'll burn the pumpo when the boilers making steam and remenber when your making steam and all those other loads come on it will effect the ability of your steam boiler to make steam aside from the fact that all that mud and rust will be circulating thru your radiant tubing unless your going to use a indirect for your radiant .Get a small modulating direct vent boiler like a munchkin and make your domestic water ,radiant and hi temp baseboard loop off it you will really be setting you custemer up with a much better deal in the long and short term and most likely bew saving them money on there fuel costs peace and good luck clammy

Looking for design help

I am relocating the heating system in a two story house and a basement. I have two different radiant zones, aloop of slant fin basebord in the basement and scattered steam radiators from when the house was all steam heated. I would also like to have the hot water made by indirect heater or on demand heater. Do I size a steam boiler for the steam radiators and then let a coil on the steam boiler heat the radiant through a mixing valve (or two as one zone is in concrete/tile and the other is under oak flooring?) Then, do I take water from below the water level and circulate it through two zones. One zone for basement heat and the other through my indirect hot water heater? Can one steam boiler handle 1000 ft of radiant through a coil, half a dozen steam radiators, a basement zone and a indirect fired hot water heater?

Looking for any advice or even some design help.

Thanks Clammy

I was leaning toward two systems and I have the space for it also. I guess I was just looking to see if anyone had put this much varied load on a steam boiler. Thanks again for your time. PlumberPaul
