Can I replace one 250 lb propane tank with four 50 lb tanks in parallel. The tank supplies a hot water heater and occasionally a fireplace. I can save quite a bit by taking the smaller tanks in to refill myself as opposed to having the gas truck deliver.

How many pounds do you use per month? You have to figure in the cost of your time and travel too. Can you fill small tanks for the same per-pound price as the large deliveries? Do you own or rent the current tank? You need to do a TCO analysis before deciding. – Carl Witthoft Sep 21 '16 at 19:16

1I think i can save a couple hundred dollars a year getting my own gas. The refill station is at a store i stop at on my way home from work so i wont waste a drive to fill up. I am renting the big tank for $99 a year, so that could go for purchasing smaller tanks. The store charges 42 cents a lb less than the delivery truck. – pdq Sep 23 '16 at 2:44
You can split the system and probably don't need 4 tanks but at least 2. If you are renting the tank and regulator you may need to buy a new regulator. Some states require restraints for smaller tanks these can be as simple as a 4x4 post in the ground with a snap chain to each tank. The post also provides a secure mounting location for the regulator. Some state require tank straps attached to the support a bit more expensive.
Look at: TANK SIZING to see how size affect BTU/hrs
I would make sure what your two loads listed total BTU/hrs fit in the tanks supply ability. Smaller tanks in parallel need to add up to be able to supply the required BTUs/hr.
You also will need to provide the proper regulator to hook into your multi-tank manifold.
I haul two 100lb tanks for the same reason you list.
I run a stove, LP dryer and tankless water heater on the two, but am considering adding two more tanks as I am pushing the limits when all are on at same time.

Yes that is true. If you use to small a tank in cold weather it could basically freeze up or not output enough to gas to operate attached devices. – spicetraders Sep 21 '16 at 19:26
