What do Killer Whales Eat? Killer whales are carnivore marine mammals, so their diet is full of meat gotten by hunting several species in their habitat. Since there are several ecotypes of killer whales, their eating habits are closely linked to the geographical area where they are located and with their population.
I have an old Crane Sunnyday 15 oil furnace with integral water heating coil for the household use. Based on my oil consumption during the Summer months, when the burner does not operate to heat the hot water cast iron baseboard radiators, I'm using ~1.25 gal/day to heat the water. I am the only one in the house, take one shower/day and wash a few dishes. I use the dishwasher for most stuff and run that every four or five days.
Heating Oil Consumption. I am trying to get a handle on how much heating oil people use. We live in a 2000 sq ft house, that has about an average amount of insulation, windows that have storms, live in the upstate New York and use an older oil burner that heats our domestic water -- it's tankless.I estimated the other day we used about 4.5 gallons per day during October which was rather mild.e live in a 2000 sq ft house, that has about an average amount of insulation, windows that have storms, live in the upstate New York and use an older oil burner that heats our domestic water -- it's tankless.
