Vedkalkulatoren

What a kilowatt-hour of heat really costs from firewood, compared with electricity in Norway

A calculator for Norwegian households choosing between firewood and electric heating. It takes the wood (species, moisture, bag or stacked cubic metre, price), the stove and the electricity price, with Norgespris or the electricity support, and gives the price per kilowatt-hour of useful heat for each, and the highest price at which the wood still pays. The figures come from NIBIO, SINTEF and the standards NS 4414 and ISO 18125. Nothing is sent anywhere: it all runs on your own device.

For: Norwegian households, owners and tenants, weighing firewood against electric heating
