True or False: An auxiliary electric heating system is typically installed upstream of the heat pump coil.

An auxiliary electric heating system is designed to supplement the primary heating source, which in this case is the heat pump. Typically, the auxiliary heating elements are installed downstream of the heat pump coil in the air distribution system, allowing them to provide additional heat to the air after it has passed through the heat pump. This arrangement is key because it ensures that the heat pump can operate efficiently, providing heat when conditions allow, and the auxiliary system can take over or assist when the heat pump is unable to extract sufficient heat from the outside air.

When installed upstream, an auxiliary electric heating element would counteract the heat pump's output, thereby reducing efficiency and negating the purpose of having the heat pump as the primary heating source. This makes the statement that the auxiliary electric heating system is typically installed upstream of the heat pump coil false. In different climates or specific designs, installations might vary, but the common approach does not support this arrangement.
