I don't think you will find anything that specifically addresses this in the NEC, but you will find it in manufacturers instructions with most baseboard heaters.
For both electric and hydronic?
210.52, FPN: Listed baseboard heaters include instructions that may not permit their installation below receptacle outlets.
I am not certain but I recall that the hydonic baseboard heaters are not a problem. Check the instructions, as others have said.For both electric and hydronic?

So, which would be the offender, the receptacle or the heater?There it is - not a code requirement but a reminder to read the instructions for the heater - which most will not allow a receptacle above the heater.

"Hey, you got your peanut butter on my chocolate!"
"Hey, you got your chocolate in my peanut butter!"
If the hydronic would reach a high enough temp there may be instructions that prohibit receptacles installed above, however I have never seen a hydronic heater that gets hot enough for that to be required - I have never seen hydronic heater instructions either though think you would need superheated steam passing through the heater to get hot enough to damage a cord draped over it, we are talking about needing an industrial steam boiler to get this kind of heat.
