Many people think an air conditioner is only for cooling. In fact, a modern inverter unit is a heat pump — and that's one of the cheapest ways to heat a home, even when it's well below freezing outside.
How a heat pump heats below zero
Instead of creating heat from electricity (like a resistive heater), a heat pump moves heat from the outdoor air into your home. Even at -15°C the air holds thermal energy that the pump extracts and carries inside. That's why for 1 kW of electricity you get 3 to 4 kW of heat.
Cold-climate models
The Polog valley can get cold, so it matters that you choose a unit built for low temperatures. Cold-climate models — such as the Siberia-type series — heat efficiently down to -15°C to -25°C, unlike ordinary units that lose power as soon as the temperature drops.
Savings versus other sources
- Versus electric heaters: a 3–4× lower bill for the same heat.
- Versus firewood: no hauling, lighting, ash-cleaning or smoke.
- Bonus: the same unit cools in summer — one investment for the whole year.
- Clean air: filters reduce dust and allergens.
Is it enough for a whole home?
For a flat or a well-insulated house, a correctly sized heat pump can be your main heating. For larger or poorly insulated buildings, it's often combined with another source. Ask us to assess your building — call 078 433 882.
