Default gas boiler -- supply and return

I own a small building with 3 apartments and 3 separate gas boiler hot water
radiator heat systems. Each boiler has a circulator pump that is attached
to a pipe that goes into the side of the boiler about half way down.
Another pipe comes out of the top of the boiler.

I am assuming that where the circulator pump is located is the return water
line that goes back into the boiler and the pipe coming out of the top of
the boiler is the supply/hot water line that sends hot water up to the
radiators to supply them with heat.

Is that correct?

Usually, but to be sure look on the side of the pump. It will have a
directional arrow

That is the usual setup. To be sure, when the system has been down for a
time, turn up a thermostat and put your hand on the pipe. You'll feel it
get hot as soon as the water circulates.

Sounds right, to me.

Thanks all. I also went ahead and looked at the pump as suggested and the
arrow does show that the circulator is on the return side of the boiler. I
just wanted to be sure.
