Heating With Domestic Hot Water

Is there a unit heater that can be used to heat using domestic hot water, Does the coil need to comply with ANSI/NSF61?

It would be to heat an apartment building stairway. The building does not have a heating hot water system but it does have a central domstic hot water system.

    You would need to check local codes

    If it were my job I would not do what you are attempting due to possible bacterial contamination of the domestic hot water system. What does the building use for heating currently?
    Cost is what you spend , value is what you get.

    X-Pump Block?

    What about using a Taco X-Pump Block?  Its made for this type of application, I have no idea what may be needed in your exact application....just an idea.

    OK, thinking out load:

    The Taco X-pump is not ANSI/NSF 61 any more than a unit heater coil. Maybe less so. A unit heater coil is copper piping (like the distrubution piping) with a bunch of turns.

    I need to look into ANSI/NSF 61.

    It will be bad enough heating with 115ish deg water much less running that water through a heat exchanger (for which I don't see any inofrmation).
