I’m curious. Why do you want to?
Can’t help though. We can’t do it with our heating because the control panel doesn’t have that option: it’s either one or t’other. Like the fridge.
I presume you mean the older S3002 unit with the fire? Yes, you can, they are both in the same fire cabinet and independant of each other with separate controls. As said, it's often a way of getting your van heated as quick as possible then one or other is turned off to maintain the temperature that's comfortable.
