Heated water storage or submarine..

[wdchuck]

Would this 14'x42"x3/8"thk, tank work for heated water storage from a wood burning source or should I just add some fins and a tower and say it's a prototype submarine or torpedo . How many gallons do you think it'll hold, it came with the house.

Can it take the pressure
I got to smal 1000L "263.9000gallon?" tanks.

How many gallons do you think it'll hold,

1,008 gallons?

Test the tank with pressure (with water in it). There is no need to use much pressure. 1 bar pressure and you can have radiator 10 meters higher than the tank. You have to insulate it too. I'd say try it.
I have 2000 litres tank in mys system and it's really convenient because it can hold warmth quite long . So you can burn wood when ever you have time to do it.

It should be around 1,150 gallons.

Actually it will hold 1007.0137 gallons using the .785 method. That may change a little if you use the 3.14 method. The formula to figure volume in a circular tank is .785 x diameter (in feet)x diameter (in feet) x length (in feet) x 7.48 (amount of gallons in a cubic foot). So it is .785 x 3.5 x 3.5 x 14 x 7.48 = 1007.137 And just for fun take that number times 8.34 (what water weighs per gallon) and that will give you the weight that will be in it not counting the tank. The water in that tank alone will weigh 8398.494 lbs. To figure the volume of a square tank is L x W x H x 7.48 . Also to figure pressure, you will gain 1 PSI of pressure for every 2.31 feet of fall you have. So if that tank is in the basement and the top radiator in the house was 20 feet above it the pressure pushing back from the top radiator would be 8.66 PSI. That is if it was open to the air at the time and didn't have heat pressure on it like the radiator of a car. I am not familiar with boiler systems or their operating pressures. Main thing to remember with water and pressure is that the higher the pressure against it, the higher the boiling temperature because the pressure keeps the gasses in the water from expanding as fast. Also the purer the water the lower the boiling point. Not that any of this matters but I saw people were trying to figure volumes for log splitters and this, so thought I would add my two cents. After a while of this at work I feel like this :bang:

Well, if it had oil in it before, would the construction be sound?, it looks like it was installed in one or two pieces. So, connecting this with a non-pressurized setup, similiar to an OWBie, but indoors, would work out okay?

Woodburner, valves, pump, heatexchanger, and other accesories could work?

The only point to do that is to have more reserve (as you know) But it can help you but hurt you also, I mean if you dont have that thing insulated good it will use more wood and not help you any... If you want to spend the money get spray foam all the way around it.

as ms10 said--and make sure you coat the outside of the foam with fire retardent material---foam applier may put on the retardent--
