Hydronic heating unit for basement

[Rockycmt]

I have hydronic HW heating. I have an unused zone on my boiler. I would like to heat my basement with it. But I want to do it with hot air. Is there a unit I can get to have the zone supply it Hot Water and A fan can do the heat transfer. Yes I can hard wire it. What is type of unit this called?

I think that is called a hydronic air handler. Do some searching to see if that produces hits for what you want.
