The cost to run a residential heat pump for twenty-four continuous hours varies significantly depending on local electricity rates, outdoor weather severity, system efficiency ratings, and whether auxiliary electric resistance heating strips are engaged. On a moderate winter day when the heat pump operates efficiently on compressor power alone, it might consume between twenty and forty kilowatt-hours, resulting in a daily cost ranging from three to eight dollars based on an average rate of twenty cents per kilowatt-hour. However, during a freezing winter polar vortex when outdoor temperatures plummet and auxiliary resistance heating strips run constantly, daily electricity consumption can easily double or triple, pushing twenty-four-hour operating costs to fifteen to thirty dollars or more. You can calculate your specific daily cost by multiplying your system's hourly wattage draw by twenty-four hours and applying your utility company's kilowatt-hour rate. You can verify estimated usage by checking smart meter data.
