What is the purpose of heat anticipators in heating systems?

Heat anticipators play a critical role in enhancing the efficiency and performance of heating systems by working specifically with the thermostat. When a heating system is activated, the heat anticipator helps to prevent overshooting the desired temperature by turning the heating system off a bit before the actual temperature reaches the set point.

When connected in series with the gas valve, the heat anticipator allows for quicker adjustments in the heating supply, contributing to a more stable indoor temperature. By anticipating the heat needs of the space and regulating the flow of fuel to the burner, it helps maintain comfort levels while also preventing unnecessary energy use due to over-heating. This process ultimately leads to improved system efficiency and comfort.

In contrast, increasing blower speed, decreasing energy consumption, or regulating refrigerant temperature are functions not associated with the specific role of heat anticipators in heating systems. These functions pertain to other aspects of HVAC system operation and do not define the primary purpose of heat anticipators.
