Who is the cheapest around I use Matheson gas just for heatiing
Depends on how much you use and how much you can afford at one time. I use ~600 gallons a year for heat, stove, fire pit and grill and own my 500 gallon tank. June/July I call around to see what the prices are and buy 5-600 gallons at one time.
There are first time customers and “leak checK” costs and discounts that have to be considered. This time of year, no one is cheap.
