do i need to lower the pressure of the boiler?

sunwave

I've heard the ideal pressure of the hydronic heating system is 12-15psi, but YMMV.
My building height is 25fts max, my boiler stays at 20psi even after i turned the nut of Watts pressure reducer counter-clock .
Do i need to do something else to lower the pressure or it's okay to have 20psi. Any suggestions?

For a typical single or two story residence, yes.

The height that really matters is measured between the lowest circulator and the highest pipe, radiator, or other component. If that number is 25 feet, you would look for a minimum static pressure of about 16 PSI. 20 PSI will work just fine.

And get a drain pipe on the relief valve. Not a good thing if it blows when you have your face close by.

And don't bet the farm on the accuracy of that gauge

I think I will add a gauge next to the pressure reducer to gain more accurate reading.

When you lower system pressure, you have to release pressure to bring it down. Open a bleeder on the top floor, then check the pressure again.
