hot water boiler residential

[Johnjohn]

Boiler experts Question please!
For two story house , boiler in the basement , 8’ for basement, 1st floor about 9’, baseboard radiation about 1’ total 18ft
1’ is for baseboard radiation length or tall? What about if u have multiple baseboard radiation on first floor. Do u need to add 1 ft for each baseboard radiation?

17' height ÷ 2.31' = 7.31 lbs add 3-4 lbs to 11 -12 lbs. You can have all the radiation there is per floor and the height of the water will cover them all. Doesn't matter if the pipe is 1" or 12" it's all the same, 2.31' per lb of height.
Bladder type expansion tank set bladder pressure to the same pressure as system under 100° pumps and boiler off. 50lb tire gauge and tire pump to adjust pressure.

Why add 3-4 lbs to 11 -12 lbs? Pressure differential cross circulator impeller

Not really sure what your asking. Your kind of just stating things.

What does "do you need to add 1' for each baseboard radiation" mean?

11 -12 lbs is more than enough. Ment to write add 3-4 lbs to 7.3 to make it 11-12lbs. Boiler and all pumps off water temp.under 100°. Ex tank air pressure the same water pressure.
