Hi Ross,With your bus complete allready, You would be better off with Hydronic kick space heaters. Theese heaters have 1/2" supply and returns, with the blowers running off 115v. A company by the name of Beacon/Morris makes some good units.I belive they come in 3 sizes, 4200btu / 8400btu / and 11400btu's. Site: http://www.beacon-morris.com/Nick-
Ross, How is your coach heated now? How well is it insulated?
I did heat it during the winter in NH for a little while with 3 1500 watt heaters during construction and they would cycle on and off. I did that until I got the elctric bill. Ross
