Drain hydronic system in advance of re-pipe ... emitter corrosion risk?
woobagooba Member Posts: 171
Hi all. Yea olde GB142 is being replaced and along with that most all of the basement piping. The system is going to be drained, most all the old piping moved/replaced, but the plan is to continue to use the cast baseboards and radiators. Question, with the system drained and open to the air, am I under any time pressure (besides that winter will return) to get the system re-piped and re-filled so as to avoid internal corrosion within the emitters?
I think it would be best to avoid draining the emitters until after the near boiler piping is done and the new boiler is installed, if possible.
Either way it would be smart to install a magnetic dirt separator on the new boiler. This will help protect the new equipment.0
Install a magnetic dirt separator as @SuperTech mentioned.
The cast iron not turn into a bucket of rust when it is drained. I wouldn't worry about it0
