What is auxiliary heat and how does it work?
Auxiliary heat, also known as auxiliary electric heat or emergency heat, is a type of heating system that kicks in when the primary heat source, usually a heat pump, is not able to provide enough warmth. This can happen when the outside temperature drops below a certain point, typically around 35-40°F (2-4°C), and the heat pump struggles to extract heat from the air. In such cases, the auxiliary heat system takes over, using electric resistance heating elements to warm the air.
The auxiliary heat system is usually integrated into the heat pump system and is designed to work in conjunction with it. When the heat pump is unable to provide enough heat, the thermostat signals the auxiliary heat system to turn on, and it begins to warm the air using electric resistance heating elements. This can be a more expensive way to heat the home, as it uses electricity to generate heat, but it provides a reliable backup source of warmth when the heat pump is not able to keep up. It’s worth noting that some heat pumps have a built-in auxiliary heat system, while others may require a separate system to be installed.
Does auxiliary heat use more electricity than a heat pump?
Yes, auxiliary heat typically uses more electricity than a heat pump. This is because auxiliary heat systems use electric resistance heating elements, which convert electrical energy directly into heat energy. This process is generally less efficient than the heat pump’s process of extracting heat from the air, which can provide up to 3-4 units of energy for every unit of electricity used. As a result, auxiliary heat systems can increase electricity consumption and lead to higher energy bills, especially during periods of prolonged cold weather.
The amount of electricity used by auxiliary heat can vary depending on the specific system and the temperature at which it operates. However, as a general rule, auxiliary heat systems tend to use more electricity than heat pumps, especially when they are operating at full capacity. This is why it’s essential to understand how auxiliary heat works and how it impacts energy bills, so that homeowners can take steps to minimize their energy consumption and reduce their reliance on auxiliary heat. By doing so, they can save money on their energy bills and reduce their environmental impact.
How does auxiliary heat impact energy bills?
Auxiliary heat can significantly impact energy bills, especially during periods of prolonged cold weather.
