# Net effective heating energy

Net effective heating energy is the part of energy acquired for a residential building that can be exploited in heating. Some of the acquired energy is wasted due to fuel conversion and transmission losses. Bet effective heating energy has been calculated by deducting heating system losses from the amount of energy used for heating of spaces. District and electric heating are net effective heating energy as such. Net effective heating energy of heat pumps has been calculated as the sum of produced ambient heat and consumed electricity. The following assumed net effective heating energy ratios have been used for other energy sources:

- Small combustion of wood 55%

- Peat 60%

- Coal 60%

- Heavy fuel oil 83%

- Light fuel oil 78%

- Natural gas 90%

The assumed net effective heating energy ratios are based on the REM model (model for calculating energy consumption for the building stock) jointly developed by the Tampere University of Technology and the Technical Research Centre of Finland.
