Sure is nice when they work correctly. I still cant get my front zone to work correctly. Did the annual service and no change. Didn't expect it to but... Calling AquaHot monday in hope they can help me. No odd noise's and no fault lights. If I can make it till summer I plan to go to the factory and get other big things replaced or fixed.
Glad to hear you got your heat fixed Mike
