I plan on using my house as the dump zone. It's a ranch with one big loop in it. It is fed from the oil boiler via a 1" down the center which then splits to each side going to the baseboard heaters then back to the boiler. So if I tap into that 1" line will I see adequate thermosiphon action with all the ups and downs that connect the baseboards together? Also I have a pile of 3/4", would that size pipe move enough hot water to do the job or is it necessary to use 1" to tie that in? Will a thermosiphon move through a swing check?
