Disconnect hydronic loops, but keep using bouler's DHW coil
I'm replacing an old boiler with a combi boiler. I'd like to disconnect the hydronic loops so I can attach them to the new boiler, but since it'll take me a few days of part-time effort to complete the work I'd like to leave the DHW connected to the old boiler till the last minute. Is there anything wrong with that? No water in the boiler, just the DHW coil, or if that's not a good idea, any options for me?
