Heat Pumps Provide High-Efficiency Space Heating

Today's consumers want comfort and energy efficiency in their homes. Today's electric air-source heat pumps provide both. This proven but advanced technology provides highly efficient heating and cooling for year-round comfort. Some potential benefits include lower energy bills, a comfortable home and a more sustainable lifestyle. In addition, eligible Duquesne Light Company (DLC) customers can save up to $200 on qualifying heat pump models.

What makes heat pumps so efficient?

Air-source heat pumps provide highly efficient space heating through several design elements. Here are some key features that contribute to their efficiency.

Heat exchange technology. Air-source heat pumps extract heat from the outside air and transfer it inside for space heating. They employ advanced heat exchangers, such as coil systems or refrigerant-to-air heat exchangers, to maximize heat transfer efficiency.

Variable-speed compressors. Heat pumps often use variable-speed compressors, which adjust their speed and capacity based on heating demand. This allows for precise temperature control and reduced energy use by matching the output to the required load.

Enhanced coils and fins. The coils and fins in air-source heat pumps are designed to maximize heat transfer between the refrigerant and the surrounding air. Advanced fin designs, such as louvered or corrugated fins, increase the surface area for heat exchange and improve efficiency.

Smart defrost control. Air-source heat pumps can experience frost buildup on the outdoor unit during colder temperatures. Efficient units employ intelligent defrost control systems that monitor and optimize defrost cycles, ensuring efficient and effective operation.

Energy-efficient fans. Fans circulate air over the coils for heat exchange. Energy-efficient heat pumps use high-efficiency fan motors that use less electricity while still providing the optimal amount of air circulation.

Make sure the units you install are ENERGY STAR®-certified. ENERGY STAR heat pumps must meet energy efficiency requirements established by the U.S. Environmental Protection Agency (EPA).

Additional ways to ensure comfort and efficiency

Efficient heating goes beyond the heating unit. These design elements and features will help make your homes more comfortable and efficient. DLC’s Watt Choices program can help you reduce energy costs while improving the energy performance and comfort of your home.

Proper insulation. A well-insulated thermal envelope is crucial for minimizing heat loss and maintaining a comfortable indoor temperature. Use high-quality insulation materials in walls, roofs and floors to reduce the transfer of heat between the interior and outside of the home. Make sure homes are insulated according to recommended levels for your climate zone.

Tight air sealing. Proper air sealing prevents unwanted drafts and air leaks, which can lead to heat loss and energy waste. Focus on sealing gaps, cracks and other areas where air infiltration may occur, such as around windows, doors and utility penetrations.

High-performance windows. When properly selected and installed, energy-efficient windows can significantly reduce heating costs. Install ENERGY STAR-certified windows, which must meet EPA energy efficiency requirements.

Smart thermostats. Programmable thermostats have been available for decades. Today's smart models provide advanced features — such as remote control and self-programming — that optimize savings, comfort and convenience. You can learn more about which smart thermostat may be right for your needs and learn how much you’ll save through DLC’s Smart Thermostat Buyer's Guide.

By combining these features with electric heat pump technology, you may enjoy reliable comfort, the latest technology and lower energy bills.
