After the installation of an electric boiler, you''re likely to see your electricity bills rise as more is needed to power the boiler. If you were to install a 12 kW electric boiler and use it for an average of 7.5 hours a day at a rate of 16.36p/kWh, this would come to £14.72 a day and £5,374 annually. That''s quite a large electricity bill ...
