I wanted to tap the vast experience here if I may on an electric garage
heater for my home. I have a 960 square foot insulated pole barn with 11'
ceilings that I want to add some heat to for winter projects. I don't have
access to gas so I want to use electricity, I have 250 volt single phase
available, can run up to a 30 amp device without running into problems.

First I know that I probably need 480 volts to get adequate heat, or an
actual 240 volt furnace, but I have what I have both power and funds wise.
I've looked at the Dayton G73 hanging unit, Any experiences with this unit?I
know that it's probably under powered for what I have to heat, but I'm not
planning to keep the pole barn heated all the time, just weekends when I
plan to work there. And I do have a propane salamander that I can get the
building up to temperature with pretty quickly, but it's too loud to use all
day for me.

Or any comments on this another unit that might be better?

Thanks,
Brian

buffalo ny: 1,000w gives you 3,415 btu's. record the temperatures and
weather. plug in some cheap used portable electric heaters up to the
limit of the available wattage. monitor their performance in your use.
use a couple of window fans to circulate the heat. that's all there
is. �you only get about 5,000 btu's from each 1500 watt heater. if 30
amps at 250v is only 7500 watts of heat it's like 25,612 btu, the
equivalent of 5 little heaters. since electricity is usually
considered efficient 100 percent to heat, give or take a blower.
[note your building construction and use determines its heating safety
requirements. example if there's vehicles or gasoline or a combustible
barn you don't run salamander open flame heaters, open pilot flame
natural gas or open pilot LP gas heaters either.] � if the heaters
pass the test thru the coldest weather conditions, the digital pyrex
food thermometer in your plastic water glass will show you the water
temperature range in its resettable hi/lo memory. other test options:
ceiling fan and remote transmitter temperature sensor.

suggest start by sealing and insulating garage, a old friend, a
mechanic used a surplus engine which he put outside, added a
generator, ran the radiator lines inside the garage. with electric
engine fan.

this got him heat in the winter, and a emergency generator out of
mostly stuff laying around. he used the engines 12 volt alternator for
charging batteries too
