Monthly cost of a 100 m² house
In a 100 m² house heating is a smaller share of the budget than in a large one, because water, waste, electricity and insurance depend on the number of people, not on the floor area. With gas you pay about 1,260 PLN a month, with a heat pump about 1,129 PLN, and with eco-pea coal about 1,142 PLN.
Fewer people means a clearly lower cost: the same house with gas and two people costs about 1,009 PLN a month. A new 100 m² house built to WT 2021 with four people and gas costs about 1,151 PLN, an uninsulated one about 1,532 PLN.
