Jun 07, 2018 · Now, if I were to use gas to heat, I would need more than 12160 kW. Indeed, I reckon 30% more. This accounts for a 80% efficiency boiler, but ALSO accounts for losses of efficiency in over-heated rooms (due to the lack of control against a time & temperature-controlled electric system). This means I would require 15796 kWh of gas.Get Price
