I have a woodgun 180 which has an 80 gallon water jacket plus approx. 6000' of 1/2" pex in floor heating (17 gallons). My expansion tank is a bladderless type suspended up in the floor joists, I think it is 15 gallons (approx. 36" X 12") and I am having the odd blow off on mild days, not really a blow off just a few cups of water leaking out. Will adding another 15 gallon tank "T"ed into the other tanks piping solve this problem. Woodguns do not use dump zones.
Also when draining the tank is it better to do it when the system if hot or cold? What are the pros/cons or bladder vs bladderless tanks.
