Yep what is the electrical load? Multiply by 10 for BTU/hr. One gallon of propane = 21,600 BTU.
Say 1000 watts needs 10,000 btus per hour. So a half gallon per hour.

Ironically I am babysitting a site right now that lost power. How many pound tank do you usually take with it and how long of run time do you get?

They start fine in the cold. There is a model with waterproof plugs, but weve never had issue with rain or snow. These are nice, i can toss it in my front seat with a tall tank in my alero, the gas ones were too big. We have 5 or six portable gas generators collecting dust now Transport of fuel and runtime are huge factors, 48 hours of gasoline is alot of gas, and youd need an external tank. Propane wont varnish your engine guts either. The only thing i dont like about propane is around here nobody will top off tanks by weight, they charge a full fill rate, so short runs are irritating. Talked to the local propane dealer about topping off from our office generator tank, but the pump would be expensive and insuring that is expensive. We have a split hose too so we can run dual tanks if we know a site will be down for an extended time. We do have some lightweight carbon fiber tanks that you can see the liquid level, those are nice. We also use a big heavy chain and padlock to keep the generator from walking away, these WILL get stolen. They have a standby with remote start and all that jazz for about 5k, its way more generator than any of our sites need, but its an option.

The more gas you need or the lower the temp the larger the tank. But for a small generator like this, I really think a 5 gallon tank will take you to below zero. Perfectly efficient 1000 watts is 3412 Btu/hr But in the real world figure 10 btu/hr per watt. If it scales linearly, a 5 gallon tank can deliver about 5000 btu/hr at 0 degrees F. So perhaps a 500 watt load on the generator. Actually I found a chart: So, assuming you need 10,000 BTU for 1000 watts, your 5 gallon barbecue grill tank will work down to 0 degrees until it drops below 20% full.

My question is why not just use gas instead of propane? What is the up side. Second question is how does the propane fair in cold weather. Say 20F or less?
