Heat pump technology is characterized by its ability to transfer heat for both heating and cooling, offering significant energy efficiency. The U.S. Department of Energy notes that these systems can reduce electricity usage by up to 50% compared to electric resistance heating. Efficiency and performance are influenced by various factors. In commercial settings, building design—including insulation, glazing, and ceiling height—plays a critical role. In residential or general applications, performance depends on mechanical factors and environmental conditions. While monoblock units are gaining popularity in the United Kingdom due to simplified installation, some users have noted they may experience reduced performance in colder climates compared to conventional split systems. Recent data highlights how dropping temperatures impact energy consumption. As outdoor temperatures decrease, heat pumps may consume more electricity to compensate for heat loss through building envelopes. For air-to-water systems, the Coefficient of Performance (COP) decreases as the temperature gap between outdoor air and the system grows. Data from the Lithuanian Energy Regulatory Council indicates that while a heat pump might produce 3.5–4.5 kWh of heat per 1 kWh of electricity at +5 °C, this can drop to approximately 2–2.5 kWh at –10 °C. ~~Edvinas Jurevičius~~ To optimize efficiency, energy consultants recommend checking the flow temperature of ~~Ignitis advises consumers~~ a building.
