QUESTION FROM jesse

I want to disconnect my existing cast iron boiler in order to move it 12 inches or so and then reconnect. I have baseboard style heaters but they appear not to have bleeder valves on them in order to drain the system down. What would be the best way to ensure the entire system is drained down. I also have a system when installed that has no shut-off or service valves to isolate the piping to the baseboar heaters , only the boiler drain at the floor level and a boiler drain right where the piping attaches to the supply side. Any ideas would be apprecited

ANSWER FROM HOME-WIZARD

Dear Jesse:

Actually, baseboard heating systems do not usually have bleeders on the baseboard heating pipes. But at your boiler, there should be purge valves. So after you shut off your boiler and you close your water supply valve, you should be able to drain your system by opening up the other valves around your boiler.

Hope this is helpful.
