Hot water boiler pressure is at 18 cold, 25 or so when hot. The new regulating valve is adjusted to the lowest possible setting. Expansion tank has 15PSI. The two zone baseboard loop is on a first floor.
I don't know if this important, but the feed is into the return line and the pumps are on the supply side.
Any reason for concern here? The manual says the pressure should be at 12.
