Whenever I change the temp on central heating, a clicking noise can be heard from my gas water heater. Could there be some connection? I dont see any, but need to replace my water heater soon and want to make sure. Thanks very much for all help and advice.
Do they have motorized chimney dampers used to reduce warmer interior air going up the chimney? Perhaps there is only one circuit that opens both the water heater damper and the furnace damper at the same time when either needs them open.
Do you get coverage you can count on? From the bag of fertilizer? From your lawn sprinklers?
