Re: [biofuel] Digest Number 1782

I'm thinking about the tank used as a secondary tank for oil in straight WVO
set-ups.  I'm not an engineer or anything, but is there any reason that the
'tank' couldn't be more of a large flat enclosed tray-shaped thing?  It
would seem that this would greatly facilitate the speed at which the oil
would heat and/ or require less heat to do it.

Anyone?

  I would guess most block, tank, or fuel heaters draw between 15 and 100
  amps.  A 75 watt Photovoltaic module would put out 4 amps in ideal
  conditions. Therefore you would need  minimum 4 panels at $350 each to run
  a 15amp heater.  More likely you would need 10 - 20 modules. My 6 panels
  give me between 1 and 24 amps during sunlight hours.

That would depend.  Here in Utah, in the summer a large flat black tank,
exposed to the sun would heat the contents more quickly than a tank with
a lower surface area to volume ratio, but then in the winter, the second
tank (with less surface area to volume) would lose heat more slowly than
the first tank.  How are you heating the tank?
