say you have a 20-30k btu fireplace how long would it approximately last with the 100lbs tank?

looking at possible alternate heat.

We lost power this morning and would of had to go outside and get the kerosene heater. But the power came back on before i had to go and get it.

propane has 91,547BTU per gallon or 21,591 per lbs. you have 100lbs. propane weighs 4.24lbs per gallon.

Buy a pellet stove like those of us that live in the bitter cold.

There are alot of variables to answer that accurately. BTU load required to heat the area. How big, how well insulated, how cold outside, window, doors, how warm are you keeping it. To get a true idea you will either need a heat loss analysis done or the easier thing to do would be try it. If you have the fireplace it will cost you a tank of gas to find out.

A medium sized generator and a small ceramic/electric heater would probably work better. It powers things that a fireplace cannot, and is portable.

Do some $math$.

A friend has one of these. He told me yesterday it cost $99 per month to run it. Dont they cost Around $400?

I dont see any saving here.

have a generator don't want it running while sleeping.to noisy, plus going to build a battery bank to run stuff during the night hrs.

I run a 30k BTU flameless off a 100# 'pane cylinder. I get a about 2-weeks, and that's leaving it run 24 hours a day as the primary heat source in the family room. Outside tems in the 20's-40's.

Way, WAY, cheaper than running the electric heat. And more conformable too.

I've got a Lennox gas fireplace I recently used during a 5 day power outtage.

Have a 500 gallon propane tank in the backyard. I really didn't notice the needle move much at all during the 5 days I ran it. Kept the house in the 50's despite being in the teens outside, and the immediate room I was in was over 60.

I have no scientific answer for you, other than I wondered myself, so just eyeballing the gas gauge on the tank, I noticed little change in 5 days.

BTW, I filled two 100# cylinders today, total cost was $79.52 for 46.3 gallons (200 pounds). That's a month's worth of heat for the core of the house. Good deal.

Running an electric heater from a gasoline powered portable generator is not a very efficient use of your personal resources.
Direct space heating with propane combustion will net 70 to 85 % efficiency, as opposed to around 18 to 25% efficiency of small gasoline engine generator.

i was looking at something like this at lowes:

20K BTU All-In-One Gas Fireplace
Now $276.75 Was $449.00

it would be sitting in the living room so would like something that would look nice in here,

i really dont know but we sell gas fireplaces at my work and even though i dont deal with them we heat the store with them and a 20 lb tank lasts about 10 hours. dont know the btu's though. if i had to guess id say 20k maybe i really have no idea.

Wow I am jealous of those propane prices!

I just removed the propane monitor heater from our game room and replaced it with a fan convector off the boiler, as the cheapest propane in our area is right around $3.25 a gallon.

Yep. A large chunk of the gasoline ends up as engine heat, which is just thrown away outdoors. Another chunk is wasted in the conversion to electricity. Only a small amount of it actually goes to heating the home's interior spaces.

Then there's the noise, the exhaust fumes, the need to replace the engine oil every 50-100 hours, etc.

Running a generator for a few hours a day to keep the fridge & freezer cold is fine, but running it 24/7 is rarely a good idea - especially for home heating.

Danner130,

What does the cylinder cost ? Is it outside the house ? How do you get it refilled ?
What brand heater is that ?

I run a 30k BTU flameless off a 100# 'pane cylinder. I get about 2-weeks, and that's leaving it run 24 hours a day as the primary heat source in the family room. Outside tems in the 20's-40's.
