electric heater or under dash conversion

[oleski2010]

that looks like a really nice unit but i wanna clean up under the hood and would like to delete the heater hoses its such a pain to try and make them look neat and clean. and for the electric heater i thought of that a little i was planning on running a diesel battery for the heater and a separate battery for the actual vehicle but i didn't think about the alt. i could always get the 180amp alt. but the alt would be working hard hmmmm.
