surely this had been kicked around many threads here and there. i get tid bits on info from each but still undecided what would be the best. with no storage and piping into my fossil boiler which has a domestic coil in it, it seemed that the best option was wood supply to fossil return and wood return to fossil supply to wood return. with the posts i have read this brings a couple concerns and seems that i will pay a price with either that i choose. at first i was focusing my design with the concern of keeping my fossil boiler warm so that my domestic coil stayed warm(plans to add a boiler mate at a later date). however i have read of conerns with this design where if i have heat demands i would have trouble supplying hot even temps to my baseboard and radiant without having wood supply to fossil supply.... any thoughts, regrets or experiences?
