We refill our 300gal tank once a month from November to March or so. Usually I fill when it gets down to 25% and they usually only fill to 75%- so that’s about 150gal per month.

Once winter is done we will go the entire summer without refilling. So probably 150gal between May and October. March to May it really depends on the year.

House is 2400sqft, we have a small wood stove in our addition with vaulted ceilings so the wood stove mostly just heats that room but on a mild day it will heat the whole first floor. Woodstove runs pretty much 24/7 from November until March. Otherwise we have baseboard heat and our hot water comes off our boiler as well. We don’t do anything else with propane (cook, run generator, etc)
