Richard,

I have decided I am going to add 100' of .500 OD copper tubing to the outside of the original coil wrapped around the tank. I will use the suggested mastic to bed everything in, and still cover the coils and tank with the ceramic wool. I am thinking of incoming water going through the outside coil first and then through the original coil next to the tank second. I would appreciate your thoughts on going from second to first or would you go from first (original) coil to second? I have been around and used the ceramic wool for over thirty years, it will completely hold the heat and not allow it to transfer to the ambient air. I appreciate both yours, and Rudy's experience, and I have no problem with either of you smacking me upside the head, and steering me straight. Yes, we had the diesel burner running, temp gauge showing 200 degrees, and still only getting warm water when in West Virginia. We always use water from the holding tank whether summer or winter trip. I even had the bay heaters on to try and pre-warm the water in the holding tank.
