Feb 22, 2019 · Therefore if we assume that the boiler, when operating, burns oil for 65% of the time, then the amount of oil used is 1.48 Litres per hour (= 2.27L X 0.65). As the current cost of oil, including taxes, is approx. €0.81 per Litre, the …

Read MoreMar 29, 2014 · They will use power, but I can't see your boiler & circs using that much. You're saying 1400 kwh/month? I'm at about 600 for whole house. Maybe get an electricity monitor and go from there. I'd get a Kill-a-watt meter (sp?) too, the whole house ones, or at least the one I have, is more of a general guide & not overly precise/accurate.

Read MoreThe climate where you live will play a role in your decision making. Oil boilers are highly efficient (averaging between 86 and 98% efficiency) but are not suitable for all regions. Tropical, dry and moist tropical areas won't get as much use from a boiler and may find it more cost-effective to use an alternative heating source.

Read MoreOil burners use a spray nozzle that delivers oil at some flow rate in gallons per hour, typically on a home, around .8 to 1.7 gallons per hour. On your boiler or furnace will be a data tag that gives the maximum recommended flow rate in gallons per hour.

Read MorePros of oil central heating. Oil is a highly efficient fuel, so you get a good return on every unit of energy. But modern condensing boilers, which use hot flue gases that are wasted in a standard boiler, are now 90% or more efficient. Replacing a standard oil boiler with a highly efficient modern condensing boiler is relatively straightforward.

Read MoreMar 01, 2004 · In one of my original posts I stated that an oil furnace firing at 1.25 gph was raised to 2.00 gph like it was rated and the home owner saved over $600 versus any previous year. I have sold oil boilers and furnaces for over 25 years to contractors.

Read MoreSep 03, 2019 · For comparison, 1 litre of oil is equivalent to about 10.5 kiloWatt hours of electricity. To run the boiler absolutely flat out for an hour, the costs would be something like this:-. If the boiler input is 50 kiloWatts, it will burn 50/10.5 = 4.76 litres per hour, delivering 50 X 92% = 46 kWh of heat. If the boiler output is 70 kilowatts, it

Read MoreMar 20, 2019 · Step 2. Determine the burner output in BTUs per hour from the appliance sticker or user documentation. The output will be in BTU (for example, 40,000 BTU). Step 3. Divide the BTUs per hour by the fuel energy content. Our burner with the 40,000 BTU per hour output divided by 1,075 equals 37.21 cubic feet of gas per hour.

Read MoreThe average home in the UK that uses an oil boiler to heat the property is thought to use around 17,000 kWh on heating. Most oil boiler systems use kerosene and one litre of kerosene equals around 10 kWh. This means that in one year, you would use approximately 1,700 litres of oil to heat your home and to provide hot water.

Read MoreFeb 01, 2005 · You're currently using 2.5 Gallons of #2 per day, which is about 350kBTU input. Given an 80% efficient boiler, that corresponds to about 280kBTU DOE output. Accounting for home size, I get 233 BTU/(ft 2 x day). Over a 24 hour period that corresponds to 9.7 BTU/(ft 2 …
