Homes that have oil central heating aren't connected to the main gas grid. Heating oil is normally used in a ‘wet’ heating system where an oil-fired boiler heats water, which provides central heating via radiators and hot water through the taps in your home. Oil has typically been a more expensive fuel, with sudden spikes caused by surges in demand, weather conditions and political unrest.
