candles aren't free
wonder what cost savings would really be compared to a running a ceramic heater at 750wts ??
That is interesting & I would seriously consider that setup in an emergency if my electricity went out & genset failed.
if you can't move the hot air around, might not be so great.
in power outage emergencies, kero or propane heaters..still have the air circulation issue, but they're generally so "over kill" heat output(in particular the common 23K BTU kero convection heaters) it won't be a big issue
in lue of that, for you slide guys, start the TM, block off the vac port (for max load on engine and blower)
Run it for 15 minutes or so and shut it down .
it will put out a tremendous amount of radiant heat
if your exhaust is run thru the floor like mine, you can close the doors while running ..it''ll be 100 degrees inside the van in ten minutes .
The engine and blower radiant heat will keep it above freezing for hours
(assuming it's not a rust bucket holes in the floor, outside in 10 below 20 mph winds)
Dirct drive guys can do it too, but you're only getting radiant heat from the blower ,which is substantial, but not as much as blower and engine like slide-ins
