Annual Electricity Kwh for heating a 3 bedroom semi detached ?
I have a well insulated 3 bedroom semi-detached house with a 13 year old 24kwh gas combi boiler and 9 radiators.
In the winter I keep the temperature at 20.5 and throughout the year I use 14,000kwh of gas.
My energy supplier said if the house were heated only using electricity that an estimate of 8000khw of electricity each year compared to 14,000kwh of gas
Could I really keep the house that warm (20.5) only using 8000khw of electricity ?
