Nobody likes opening the electric bill after a brutal January cold snap. That is why one homeowner’s result in northeastern Poland stands out.
According to the reporting you shared, Irena, who heats her 118 square meter end-terrace home near Bialystok with a heat pump, expected her January power bill to reach at least PLN 2,500.
Instead, the invoice came in at PLN 1,262.60 under Poland’s G11 tariff. For a home exposed more than middle-row units, that is not a small surprise. It is a reminder that modern heat pumps can still perform well in harsh winter weather when the system is used and maintained correctly.
Why heat pumps can still hold up in real winter
That matters beyond one household. Heat pumps are often judged on the coldest days of the year, when anxiety runs high and every extra kilowatt feels personal. The U.S.
Department of Energy says heat pumps are now an energy-efficient heating option “for all climates,” and notes that newer air-source models have become a credible choice even in colder regions. It also says some cold-climate heat pumps are designed to operate in temperatures as low as 5 degrees Fahrenheit.
In practical terms, that means the old idea that heat pumps simply stop making sense in real winter is, for the most part, outdated. But there is a catch. Performance still depends on the basics.
The maintenance details that can change the bill
The Polish report highlights one of the most overlooked chores of the season, keeping snow away from the outdoor unit and the surrounding space.
That may sound minor, but it is not. DOE guidance says proper operation and maintenance help ensure efficient performance, while Building Science Education materials tied to DOE note that outdoor units need clear space for airflow and must be kept out of trouble from snow and ice. When airflow is blocked, efficiency drops and bills can climb.
There is another piece homeowners sometimes miss. DOE also warns against thermostat setbacks that trigger backup electric resistance heat, because that backup mode is usually more expensive to run. So yes, the machine matters. So do the habits around it.
What readers should keep in mind
What should readers keep in mind? A single bill does not prove every heat pump will be cheap in every house. Insulation, sizing, layout, tariff structure, and outdoor temperatures all shape the final number. Still, Irena’s case lands at the center of a bigger debate.
When winter really bites, a well-maintained heat pump may hold up better than many people expect.
A useful reality check.
