Picked our Premier up June 28! Fire place spec. says 12 amps. I would not use it for heat and run the microwave at the same time. So far our only problem is the awning lighs have quit working. Obviously both A/C'S would be over 30 amps. Running elect water heater at the same time as anything like A/C or fire place might not be a good idea.
Had 30 amp on our old unit and had that happen more than once. It is easy to forget what you have on and turn on micro wave or elect heater! But you can get by if you are carefull!
