What size propane tank do you have & why?

Recommended Posts

Finally got my gas forge up + running! Have a standard 20# grill tank on it and have been considering a larger one but am looking for advice. The 20's are readily available & easily refilled, but don't last real long and can freeze up. Been thinking of either a 30, 40, or 100# size- I like the capacity of the 100, but have a few reservations and would like to hear others experiences.

I run 20s and 40s. I'd rather a 100lb, but don't have a place for it. The nice thing about a bigger tank is, it won't freeze up as fast and you can usually draw out every little bit in the bigger tanks. I hate freeze ups. If they do freeze, grab a bin or muck bucket, put the tank in it, fill it with water and strap it down. It won't freeze that way. They will float so you have to strap them down. Water doesn't have to be hot either. Straight from the hose works fine

For me a BBQ tank will last a good long day on my forge and I have about 5 of them.  As mainly a weekend warrior these days, they do me fine.

I was recently given a full 100# tank and I have an old one of my own; but they are a pain to get filled as my current pickup has a cap and the propane place won't allow tanks to be laid down.

Freeze up is location dependent; not usually much of a problem here on the border of the US and Mexico. Where BB is; who knows!

Large tanks are fine to use, but not so fine to move around to get them filled. Smaller tanks can be ganged together, to slow draw rates and avoid freezing just as well as large tanks.

I got tired of dragging 100# cylinders in and out of my shop and loading and unloading them so I set a 500 gallon tank and plumbed it into my shop.

Do you rent the 500 gallon tank, or did you buy it?

Is the cost of delivered propane much different that what you previously paid?

I bought the tank. It was costing me $50 to fill a cylinder and it holds about 24 gallons. I filled my 500 gallon tank for a $1.30 a gallon. A lot of times it’s cheaper than that if you fill around August.

I dont know if I agree with that. It gets hot in northern Illinois in the summer and I've had them freeze on me.  Propane will freeze the tank from the draw, not just weather dependant

I use a hundred in Colorado and so far no issues with freeze ups. Smaller ones have been an issue. There I a 500 gallon outside that we use to heat the shop but teeing off of that heater line does not have adequate flow. Need a higher pressure regulator on the tank for the forge??????   Not sure how that works.

Furnaces are usually set up for inches of water column pressures.  15 psi is 34 *FEET* of water column.

I have a 500 gallon tank that is plumbed into the shop that runs three different gas forges and a big oxy/ propane rosebud torch.

The torch is supported by two 250 cubic ft. O2 tanks manifolded together.

This gives me the best price and avoids the time and hassle of running to town to fill smaller tanks. 

The  local gas company comes out and fills it about twice a year

For using the propane forge at home, we have a 150 gallon tank that our gas supplier will fill when we get gas for our 500 gallon home tank.

For taking the forge to meetings or hammer ins, we have a 30 pound and 20 pound tank for portability.

I have a 7 gal tank but my dad just gave me 2 25 gal tanks. The 7 will freeze up on me if its cold and low. We will see how the 25's do

Have 2x 7gal tanks, to change them if one is empty. Since I use them with the air forced burner on 14psi I have 1/4 less consumption in comparison with the pure Venturi burners. One tank is good for 1 to 1  1/2 day forging or melting pleasure. Add next to the regulator/reducer also a hose break valve and an flame extinguish valve to avoid back flash to the tank after the earlier chimney effect on the Venturi's. Now I close first the gas supply an than the needle valve for pressurised air. Till now I mention only some frozen air condensation on/till the gas level remains in the cylinder and never a frozen reducer valve. After my knowledge its only become annoying when the reducer freeze in or even critical if the (propane) cylinder or environment  reach a temperature below -47F. This is the reason to use propane instead of another gas like butane or LPG. Please correct me if I’m wrong.

I have a 60# small enough to load on the pick up and take to get filled and it gives me about 40 hrs of forging time.

One of the reasons I'm tolerant of people's choices in heaters is that they can always be upgraded. So weed burners can be switched out for forge burners whenever someone decides they don't like a large fuel bill.

Had my decision made for me, Tractor Supply had their 100# tanks on sale for black Friday so I grabbed one.  Price for gas fill works out cheaper too.  I had been looking at one on CL, but it was almost at retail price & may have needed hydro-testing. Had the seller been a bit more flexible on price I might have got it, but I'm happy with what I have.    Forging on...
