John, I see your and Bills point on the heat exchange efficiency, I will bring this up with ITR. I can't check my system because I pulled the relay board to repair it, but will try the test when I can. I wonder if the main point of the engine heat is to have the engine exchange heat to the hot water system when the engine is running? Adding a pump wouldn't be hard but maybe a block heater would be just as good.

Robert,

Of course that is what the engine heat is for. Why waste fuel to heat the hot water heater and the interior of the coach, when you are generating heat already.
This reminds me, on my last coach, the hot water heater was also heated by the engine coolant, but I don't know if it had an internal exchanger or an external copper coil that wrapped around the hot water heater tank. All I know is the water was very hot when you reached your destination. It also had an auxiliary heater at the foot of the bed that was heated by engine coolant. It put out some good heat when traveling down the road.

Adding a block heater is an option, but not an ideal one, especially if one likes to boondock a lot. It would take longer to heat the block using a block heater, and the generator would consume more fuel. Also, installing a pump would be much easier to splice into the existing heater hose without the need of draining the whole block, which you would need to do to install a block heater.

It is too much text to read, sorry. Can you tell in a few words the main idea of that dialog? It would be good to read the description of the problem and then the possible solutions if they exist. I realize it is a lot of additional work for the author, but you will sure get more bonuses from your visitor. I mean your audience will be growing. Nowadays, people prefer simplicity and visual content.
