Finally getting around to adding a thremalsyphone dump zone to my set up for a failsafe incase my back up power has an issue or if the circ on the boiler dies. Looking at baseboard output, looks like 3/4" will get me 680 btu/ft @ 200*. I seem to remember reading somewhere on a post that the dump zone should handle 10% of boiler output, I have an EKO 25 so 10% is 10,000 btu's or about 15 ft of base board, I have plenty of base board so I will probably do 20 or 25 depending on space. Does this all seem reasonable, also is it worth adding some pitch to the dump zone to aid in the flow? If so any suggestion (1/4"/ft?)?
Thanks for any input.
