Steam boiler with baseboard loop

I have a steam boiler with a domestic coil, customer wants to use the domestic coil for a baseboard. Can I just get ride of the mixing vale’s, add a pump, airseperator, expansion tank, bleeder, pressure reducer and check valve. Have the pump come on with a switching relay. Am I missing anything. The costumer also opted to install an electric water heater. No gas in house. And hard water coming in house.

    Tridicator, 30 lb. relief valve, and back flow preventer.
    Just pipe it like any 1 zone boiler.

    Oops forgot the pressure relief valve, I went Friday to install it, I stoped and installed a fitting for the valve I will finish it in Tuesday and maybe take a picture.

    Depends on what you are talking about, could you grab some fitting and throw it in,yeah, will it work? who knows? you need to know the size of the coil, the btu's you need, the flow rate, is the coil still being used for hot water? what is the coil capable of? forget boiler size, chances are if it's a small addition requiring only 6000 btu's it might work, what the hell, hold some fingers up from across the street and measure the AC size while you're there. - sarcasm

    was the coil used at one time and taken out of service due to scale build up?
