Heating valve on dedicated circuit?

[darekelec]

I know heating equipment needs to be on individual branch circuit.
Does a single valve for circulating hot water in heaters need to be on individual branch circuit?
Water is supplied by building's boiler and 24V valve is Installed and energized in apartment.
There are 10 other apartments with its own valves controlled and energized by each occupancy.
Thank you.

JMO, but the valve is not a heating appliance. It also is something that only draws maybe 5-10 VA, with maybe a brief inrush of 100-200 VA.

I myself would rather see it on with a lighting circuit then on an individual circuit, should the circuit go down, it will be noticed sooner if some lighting isn't working then if just the heating stops working.

Thank you for your answer. But what's a JMO?
Do you know code section it says about heating appliance to be on individual branch?
I couldn't find the part so I was missing the wording.

JMO= just my opinion.

Code section you are likely thinking of is 422.12.

exception 1 permits aux equipment associated with the central heating to be on the same circuit as the central heating, would indicate to me that aux equipment, which I think the valve you described is just that, could be on other general purpose circuits.

I don't think there is anything wrong with putting power for the valve on a lighting circuit in each apartment, it's not really different than a toe space heater in a kitchen.

Besides if you put them all on the boiler circuit you would have to give all ten apartment dwellers access to the house panel. 240.24(B).
