I am redoing the basement . When i removed the "old" paneling i found no insulation on the block walls. I decided to to build out the walls with 2x3's to save some space. The hot water baseboard runs to close to the walls to build them out, can i cap off the water to the basement ( seperate zone ) while building the wall and finishing ?. I would like to install new baseboard anyway.
And should i drain the entire system? i am having pop off problems also . Any help will be appreciated . Thanks in advance.
If the boiler is popping the relief valve it means 1) the automatic fill valve is letting too much water into the system 2) the expansion tank needs to be drained 3) you might have a bad relief valve. The boiler should run normal at about 15-20 psi on the gauge and about 180 deg. water temp. More than 30 psi or 220 deg. will open the relief valve. Of course you can drain the system to replumb the basement. You will need to vent all the radiators when you refill the system.
