Hi guys, thanks for the all the great insight I have already gotten from just reading the forum. From what I have read, I ended up replacing my Hearthstone I with a Max Caddy. So far so good, and I am hoping to cut down my wood consumption, or at least be more comfortable. My question is about the hot water loop, and the back up electric element available for this unit. Has any one used the domestic hot water loop? Is it effective? Do you guys know what amperage the electric heat element draws? Thanks in advance, and bring on the cold.
