New propane heater install

[pagreenpool]

I'm getting info on installing a heater. We have a 22k in ground pool, live in eastern PA. Our home is oil heated, but I have a 100 gallon propane tank for the oven.

In my research, the consensus seems to go with a larger heater (more BTU) to heat the pool faster. So I'm looking to do that, however I feel I might be limited by the size of my propane tank or possibly even the hookup - there is already a line ran from the propane tank to the pool, it's 3/4".

So if I get a 400k BTU heater, is it going to rip through that 100 gallon tank? My options are get a 2nd 100 gallon tank, or we are thinking of possibly buying a larger tank (500 gallon or 1000 gallon), and eventually switching the house heating to propane.

Thoughts?

One gallon of propane is approximately 91k btus, 100 gallon tank wouldn't last very long.
Using that much propane you would probably br better off with heat pump or solar.

A 400k btu heater burns 4 gallons of propane an hour when it is heating

Get a second tank or just one large one as you mentioned.

Thanks for all the feedback. I have a 3/4 inch line already ran to my equipment pad for the propane hookup. Is that size line going to limit the size heater or can I still get a 400k BTU? What is the point of getting anything less than 400k?

Is there going to be a second stage regulator there by the heater? Usually they run the propane under high pressure and use a small line so I would guess that you have 3/4" pipe showing above ground but the smaller copper line underground which is normal. I see no issues with it.
