1000 gallon propane tank

Expansion tanks

Very nice - Neat and clean.

Nice Pics!  Do the LP tanks that you use for storage already come with the bulk head fittings?  I haven’t seen a pic yet with a HX plate yet?

1000 gallon propane tank

SIzzler, any chance you could detail what each of those pipes are doing on your tank? I am setting mine up this summer, and was only planning on a in on top, out on bottom, and perhaps a temperature probe...clearly there is a lot more going on with your tank.

Inquiring minds want to know…

The tank arrived from the factory with five fittings on top and one 1 1/4” drain plug on the bottom. The top connections were of various sizes....... 1 1/4”, 1”, 1”, 3/4” and 3/4”.  I added three 1 1/2” Weldolets to the top of the tank and capped off both of the 3/4” inlets.

What you are seeing in the photo’s from left to right are

1 1/4” inlet (feed from boiler main loop)
1 1/2” add on ( 12"galvanized pipe nipple with 18” long reach thermometer monitoring tank temps)
1 1/2” add on ( 8"black pipe nipple with psi gauge)
1” supply line from tank to house baseboards and DHW indirect (house loop -draws hot water from top of tank)
3/4” capped off (this is the line tipping back towards the wall)
1” return from house loop (returns water to bottom of tank)
1 1/2” inlet add on (feed from boiler main loop)
3/4” capped off

We might have gotten by without adding the additional tank fittings but figured this way I will be covered if another zone or more gauges are needed. We have a 1000 sq ft shop attached to this garage that will likely get tied in also. The boiler return comes from the 1 1/4” line at the bottom of the tank.
