Got 6 people taking showers & doing laundry & doing dishes with DHW thru the oil boiler. The (Once) friendly neighborhood oil delivery person stopped by on his monthly schedule to top off the tank & I'm surprised he didn't leave the delivery slip stuck to the front door with a dagger. 21 gallons (*snicker*)... Every drop means he parks at the top of my driveway & has to drag 80 -100 feet of hose down to the tank... They are basically delivering for free, altho I DID overpay them on the budget plan 5 years ago for the oil. That just happens to coincide with the timing of our first pellet stove (P43) install...We're STILL $400 in the black...Have I mentioned how much I love my Carbon Neutral, Environmentally Friendly, New England Compressed Sawdust Burning P61A?
