Default dhw from wood

Wish I had caught this. I heat my dhw with wood heat year 'round. Part of my plan to become independent of the grid. NO, and I repeat NO wood fired boiler should be aloud to reach temperatures above boiling when used in a domestic application. Your T&P valve on your water heater should not real ease until 90 psi or 200 degrees. Even the best heat exchangers will not be able to hear your water heater past 200 degrees even if your burner water temp is at boiling because there is too much heat lost throughout the system.


Dump zones are used where there is a potential for a chimney of a burner to create an uncontrolled fire during a power outage and that's about it. I'll explain all this when i get around to my burner build write up.
