Jack,
In our AH units, the hot water loop is a long coil of copper tubing wrapped around the outside of the boiler tank. That is done to provide a double barrier between the ethylene glycol coolant and drinking water. As Rudy stated, is difficult to blow air through the many wraps of tubing and get the water out.
As long as the electric elements are on, you will be fine. If the diesel part of the unit is working, turn them both on. The diesel will not run continuously unless the electric fails to keep the unit at temperature. The thermostats for the electric are just a few degrees higher than the diesel. Clever.
