Heat Pump 101
Heating, ventilation, and air conditioning (HVAC) systems have a limited lifespan, and with proper maintenance, that span might reach beyond 25 years. With such information, homeowners should have sufficient time to plan and budget for system replacement. During this planning stage, wise homeowners research their options to make a wise choice that will impact family comfort for the next 25 years or so. If you are considering HVAC system replacement, consider heat pump technology in a dual-fuel configuration.
What is a Heat Pump?
Heat pump technology uses the same process for air conditioning and heating; the same components are used all year round for greater efficiency. How does it work? It helps to remember a little physical science.
Heat pump heating is several times more efficient than electric or natural gas furnaces since the electricity used by the system does not generate heat but moves heat from one environment to another. Most systems include a backup furnace system for the periods when the outdoor temperature drops below 32 degrees—when the air has less heat available.
Since this is a technology, it can be transformed and adapted into various arrangements to customize its usefulness for each residential setting.
An installation technician can discuss installation options that most closely match a home’s existing configuration and heating/cooling needs.
The transfer of heat requires a lot of air movement. A large fan moves air across a network of tubes and fins in the outdoor condenser unit. Every two minutes, a blower motor moves the entire volume of air inside the home across another network of tubes and fins. Anything that diminishes the airflow reduces the efficiency of heat transfer. This is the major reason manufacturers and HVAC techs emphasize air filter changes and regular system maintenance.
