How to remove the air from your boiler / heater
Hey Dominic. Thanks for the video. I have a few questions.
1. The experts who installed my system didn’t put a shutoff valve on each of the zones. The only valve in the line is the zone valve that receives the signal from the thermostat switch. I assume I need to turn the heat all the way down and then open the boiler drain as you describe in your video.
2. It is about 20 degrees here right now. My water pressure is just under 30 psi. Is this normal? Is this ok? Is it safe?
3. There is a boiler drain at the very bottom. Am I supposed to open that periodically to let debris and contaminants out?
