What size do they actually call that 120 Gal Tank...?
The reason I ask is last winter my sons installed a natural gas furnace in my shop that they converted to Propane for me...and since the shop is located where the Truck can not reach it with their 100 foot hose I have been using
100 POUND tanks... one connected and 2 in reserve.. each holds about 22 gallons... My plan for this year (or next) is to buy a tank and install it near the driveway and trench a line back to the shop...
As it is I do NOT heat the shop...but when I ENTER I fire up both the 116,000 BUT furance and a 30,000 Ready heater...the ready heater blasts the chill off and within 20 minutes the shop is in the mid 60's even on 10 degree mornings... used less then 10 gallons of Kero last year and used 5 tanks (hair over 100 gallons of Propane)
Major reason is that with 30 inches of snow on the ground I had a hell of a time swapping out the 100 POUND tanks...especially with the drifts... lol
The furnace was brand new never used (but was installed) in a new home that was susposed to be heated with oil...lol .. the boys got it for free ...someone was covering their butt in their companies home office I guess...
