Boiler comparison

Fuel price → cost per kWh of heat by boiler type

Tariffs

Heat demand, kWh/season

Gas (грн/м³)

Electric (грн/кВт·год)

Pellets (грн/кг)

Firewood (грн/складометр)

Heat pump (грн/кВт·год ел.)

True heat cost = fuel price / (calorific value × efficiency). A heat pump multiplies electricity by COP 3–4 — cheapest heat, but capital is 200–400k UAH. Gas is 2×+ cheaper than electricity at current tariffs. Pellets are mid-range, firewood depends on cut quality. Adjust prices to your tariffs.
