Hmm unsure if that’s correct. I burned 8.12 us gallons yesterday where temperature outside was 28 deg Fahrenheit max and 25 deg min. This includes hot water use

Hmm unsure if that’s correct. I burned 8.12 us gallons yesterday where temperature outside was 28 deg Fahrenheit max and 25 deg min. This includes hot water used for bathing/showering, washing clothes, dishes etc. are you implying In UK Argus is achieved @ .812 gallons. I question that level of hone efficiency, although don't dispute there can be some homes that are quite efficient. I know that for example in Germany boiler rooms tend to be immaculate, neat rooms, not the typical dark basements.
Even in Europe, in places like Germany roughly half of the country's 40 million homes are heated with natural gas, a quarter with oil and almost 14 percent with district heating. District heating in Germany is mainly powered by natural gas and coal, while waste and renewable energies contribute a smaller share.*
So 10 million German households use Oil for heating spaces and water vs approximately 5.5 million in US.

- londons_explore 5y ago2500 square foot average US home, on two floors, has 1250 square feet of roof, 1250 square feet of floor, and 2240 square feet of walls. Total: 4740 square feet. Assume all of these are insulated with 6 inches of cheapo polyurethane foam board insulation, with R value 6 per inch. So total heat input required for 68F indoors is 5000 BTU/hr. 1 gallon of fuel oil has 138,690 BTU's in, so at baseline, you shouldn't be needing more than one gallon of oil per day, even with your existing furnace. Obviously, humans generate some heat, as do appliances and stuff, so in reality you might need less. You also probably have losses through leaks and less-insulating windows, so you might need more. All this assumes there is no brick or wood holding up the house (that obviously adds a little extra insulation on top of the foam), and assumes the ground conducts away heat (when actually it has quite a bit of insulation itself).
- pettycashstash2 5y agoSomething is wrong with your calculations. Average Heating Oil Usage-Based On Square Footage* the size of your home can greatly affect your average home heating oil usage. Below, we list down the estimated fuel consumption for every 1,000 square feet of space in relation to the average temperature outside: 10 degrees Fahrenheit: 3.27 gallons 20 degrees Fahrenheit: 2.67 gallons 30 degrees Fahrenheit: 2.07 gallons 40 degrees Fahrenheit: 1.47 gallons 50 degrees Fahrenheit: 0.87 gallons In other words, if the average home in the US is at 2,687 square feet, you’d be using 5.56 gallons of oil in a 30-degree day. However, if you have a bigger home with, let’s say, a 3,500 square feet space, you’ll need around 3.5 times more heating oil than what’s listed above. The same goes if your home is smaller. from https://www.myhomeenergyct.com/fuel/how-much-heating-oil-will-i-use-a-day/ https://www.myhomeenergyct.com/fuel/how-much-heating-oil-wil...
- londons_explore 5y agoIt's because the vast majority of american homes are lucky to have 1 inch of insulation, not 6 inches. Usually the insulation is between batons [eg. 1] rather than on top, so you lose lots of heat through the batons. Lots of US homes don't recover heat from exhausted air either. Basically, poor house design is a big contributor. Foam is super cheap both to make and to install, so I don't really see why the situation is as it is.

- pettycashstash2 5y agoagree to a certain extent. Standard wall cavity is 3.5" for a 2x4 wall and 5.5" for a 2x6 wall. 1 inch is exaggerating a bit :)
