Heater power calculator
Heating power demand selection:
40 W/m2 - very good building heat insulation and other favorable factors: the minimum loss of ventilation and heat, building orientation to the south, i.e. building corresponds to energy efficiency class A +, A ++ (according Lithuanian classification) and passive house requirements.
60 W/m2 - very good building heat insulation and other favorable factors: the minimum loss of ventilation and heat, building orientation to the south, i.e. building corresponds to energy efficiency class A (according Lithuanian classification) requirements.
80 W/m2 - good building heat insulation - newly build house or insulated old building, but there are unfavorable factors: the average loss of ventilation and heat.
100 W/m2 - the average building heat insulation - newly build house or insulated old building, but there are unfavorable factors: the large loss of ventilation and heat.
120 W/m2 - satisfactory building heat insulation - the old building, new windows, insulated some of walls.
140 W/m2 - poor building heat insulation - the old building, old windows
