Air Source Heat Pumps (ASHP) prove to be both cost and energy efficient to a homeowner. ASHP are used for both heating and cooling a home, as well as heating the water tank. On average, these pumps are able to produce up to three times more heated energy than the electrical energy needed to operate. Here are a few points to consider when looking into an ASHP for your home.
Outside air of almost any temperature above zero contains heat. These pumps work by then pumping it from the outside air to provide warmth to water or living space. This can also be done to cool the inside of a home as well. ASHP come in two different types, a split system and a packaged system, and with a variety of options.
The split system typically runs off of three main components, a compressor, the indoor exchanger coil, and the outdoor exchanger coil. The outdoor coil extracts the heat, while the indoor coil transfers it into the indoor heating distribution system or water tank. This explains why the higher efficiency of the system directly depends on the outdoor temperature being above forty degrees Fahrenheit.
All three components of the packaged systems are typically located outdoors. The warm air is delivered throughout the home from duct work run through the wall or roof. An option with the packaged system is a ductless room heat pump. They are usually ran through a wall or installed through a window. These provide the highest efficiency for apartments or small homes.
One of the biggest advantages to an ASHP is that the same system can be used for heating and air conditioning. Another advantage is the cost efficiency compared to other sources, such as an electric heater. They have been found to give off four times less heat than an ASHP, while using the same amount of energy. ASHP also have a long life span, many lasting over twenty years, and require low maintenance.
A downfall of ASHP is the direct relationship between efficiency and outdoor temperatures. If the temperature falls below forty degrees Fahrenheit, the system's energy efficiency falls with it. Homeowners who live in warmer climates, but experience a winter with below normal temperatures could run into unexpected problems. Other problems such as leaky ducts, low airflow, or incorrect refrigerant charge can usually be easily fixed or avoided with proper maintenance and correct installation.
ASHP technology is working to improve systems and provide optimal performance for homeowners. A recent development created to give homeowners more choices is the reverse cycle chiller. It gives a choice in heating and air conditioning distribution systems, such as radiant floor systems. Another advance that is well on its way to completion is the cold climate heat pump. This pump features two cylinders on a two speed compressor, creating a system that should operate at optimal efficiency despite cold temperatures.
Air Source Heat Pumps can be a great cost effective solution for heating and cooling your home. The key to the greatest efficiency comes from the research for your home. If your home is in the appropriate climate and has a compatible layout, an ASHP system could start saving you money today.
