Trying to get both the BR and the LR to 70° on electric only at 45° outside is probably not going to happen especially if both zones are calling for heat. We usually have the LR at 68 or so and the BR at 62 or off and can manage down to 40 or so before we add diesel. If electric is not quite enough to get to the comfort level you want turn on the diesel.
Sometimes we will turn on the electric and run the diesel through a cycle to get the AH juice up to temp quickly. Then shut off the diesel and let the electric keep up. It takes about 20 min to get to full temp on diesel and about 2 hours (to a lower set point) on electric with no loads on the system.
We added a switch to turn off the dash blower when the LR callse for heat. There is a relay in there that does this when the ignition is on, you just have to add the switch into that circuit. This makes the back blowers and heat exchangers run longer. The heat distribution in the LR seems much more uniform to us. With the front blower on it blows warn at at the thermostat and the zone shuts off sooner and cycles more frequently.
