When you purchase your next heat pump, consider available options for improved efficiency.
There are a wide variety of options using advanced technology to provide heat and air for your home. For example, heat pumps with adjustable capacity are the most energy efficient. The blower and compressor operate according to the heating and cooling requirements of the house at a particular time. These heat pumps seldom operate at maximum capacity, reducing noise and saving money.
Zoned Heating and Cooling System
Zoned heating and cooling systems are popular for efficient energy use. The airflow to different zones or rooms in the home can be independently controlled through a zoned system, allowing control over heating and cooling, anywhere and anytime. This type of HVAC system is fitted with motorized dampers and a thermostat with multi-zone program options. Air handlers with adjustable output ensure optimal efficiency.
Standard compressors allow heat pumps to operate only at the highest capacity. On the other hand, heat pumps fitted with two-speed compressors can be used to heat or cool at the required capacity. This feature reduces energy costs and protects the compressor from wear and tear. If your home is large and is fitted with a zone-control system, you can maintain different temperatures in different rooms with the help of a two-speed heat pump that comes with self-operating dampers.
Dual-speed or variable-speed motors present on outdoor fans or blowers maintain the air velocity at a comfortable and consistent level, which ultimately reduces the utility bills. Since there is no need for the blower to continually operate at the highest speed, noise reduction is another added advantage.
Desuperheater Heat Pumps
A desuperheater is the hot water component of a geothermal system. It heats water at a speed twice that of a normal water heater, by making use of the waste heat released by the pump in cooling mode. Compared to the piston compressors present in ordinary heat pumps, scroll compressors are better at pushing the refrigerant into increasingly smaller areas. This leads to a noise-free, longer operating life.
In addition to electric-resistance heaters that can act as a backup in cold climates, burners operating on a range of fuel can also supplement heat pumps. Backup burners address heating requirements in extremely cold conditions while reducing the electricity bill. Most heat pump manufacturers do not include both kinds of heat supply within a single unit, but the same ductwork can be conveniently shared by two smaller systems.
