You may want to contact the gen set manufacture to see if the genny can go

24/7in that condition. you may be able to install a thermostat to control
the block heater, this way its not always on. PS I would use the Outback
About the carb heat idea...LP is a liquid at -44°F. The liquid does not
combust, it must be vaporized. As the ambient temperature drops closer
to the LP liquid temperature, there would be a reduction in how fast
liquid is vaporizing and therefor a reduction in volume. What you need
in cold
Hi guys,
I don't live in super cold.
I'm curious about the block heater part. With the good synthetic oils that are

Is the issue heating the block or battery or heating the intake for propane
units?
Thanks

Heating the regulator won't help if the propane is not vapourizing. You
would need to heat the tank.
However, you do not need to heat it very much, just enough to let it
vapourize. Think about putting it somewhere with a little heat, or burying
it.

Chris,
After I hit the send button, I thought about how a small generator or
gas grill will use tank pressure through a vapor regulator. If this
generator is plumbed that way, there lies a problem that your solution
of heating the tank will work with. Personally I would not plumb a
generator
Hi Chris,
LP will boil (vaporize) at -44° so until your ambient temperature is
below that it is vaporizing. Heating the tank will increase the liquid
and vapor pressure in the tank but it is still liquid, not vapor, that
is plumbed to a cold regulator, or vaporizer if they have one, where the
Hi Dana,
I have an off-grid client (central/northern Alberta) who tried this but the
heat from the gen would shut down the magnum inverter due to over temp. This
was in an enclosed room (~15'x15') in a much larger shop.
The gen was being exhausted outside but it was an air-cooled unit, so blew

Wrenches,
I'm curious what strategies you use to preheat a propane gen in cold climates.
This is a large off-grid design in a sub-zero winter climate and ideal would be
to turn on a block heater
We have installed many low ambient temp propane genset and here are a few
suggestions. I would recommend underground 1k propane tank this allows
constant 50* temp improves the evap rate of liquid propane and prevents fuel
starvation /lean burn conditions due to low evap rates. Primary reg set

Hi Gary,
We have implemented a preheat strategy that has really worked well at a
site using dual sunny islands. They have a load shed function built in
with the control relays. We are using that function to add the block
heater load. When a generator start is likely (~50% SOC) it triggers a

to turn on a block heater an hour or two in advance, then run the gen cycle. We
plan to use either a Schneider XW or Outback
Gary,
Mac's approach is intelligent and will work well, as an automated
system with the right hardware. We took a quite different approach
on a somewhat similar scenario in 2009.
