With the arrival of a new extreme cold wave in Rosario and the region, Argentines face the challenge of keeping their homes warm without skyrocketing electricity and gas bills. Among the available electrical alternatives, there are significant differences in energy consumption and initial cost. Air conditioning, although it requires the highest initial investment (between $600,000 and $1,400,000) and professional installation, offers a dual heating and cooling function, with a consumption of approximately 1,000 watts per hour in heat mode if it is an inverter model.
