Engine Pre Heat

Heating the pink antifreeze should not hurt it or the system any and I will drain it as soon as I hit Oklahoma. I guess something is better than nothing. I hope it warms up a bit in the next couple of weeks. Thanks

It will take awhile for the electric element to get the tank up to temp so the more time the better. With just the engine preheat turned on the electric element should be able to keep up. It won't hurt a thing to have the RV antifreeze in the fresh water loop while the HH is fired up.

Another HydroHot question: It appears the temperature is falling even farther for the day we want to leave. Current temperature estimate is low teens during the day and 2 degrees for the night before we want to head out. I spoke to the building owner (where the coach is stored) and he agreed that I could run the HydroHot to heat the engine IF it did not take to long. Does anyone have a idea on the time it would take for the HydroHot, running on diesel, to warm the engine before trying to start the coach?
