Read More4. In operating a boiler with dual fuel capability, which is the lowest cost of fuel given the following? Natural gas $4.00/GJ efficiency = 92%, Fuel oil $123/ton efficiency = 88% (42,000 kJ/kg) (A) Natural gas (B) Fuel oil 5. A 1000 square metre building
Read MoreA 24 kW boiler will use 24 kWh of energy per hour. According to Choose, the cost is approximately 3.8 pence per kWh, which means it would cost around 91 pence to run a 24 kW boiler for one hour. This will change depending on the cost of gas and the size and age of your boiler. According to Ofgem, the average gas consumption of a UK household

Read More2009/11/13 · There is a large potential to reduce primary energy use and CO 2 emissions from the Swedish building stock. Here detached houses heated by oil, natural gas or electric boilers were assessed. CO 2 emissions, primary energy use and heating costs were evaluated before and after implementing house envelope measures, conversions to more efficient heating systems and changes to biomass fuel …
