How to Choose an Electric Actuator

1. In areas with centralized heating, use normally open electric heating actuators.

Reason: Centralized heating systems are typically found in northern regions, where the climate is colder. Residents use electric heating actuators and thermostats primarily to save on heating costs in communities where heating is billed based on metered usage. Hot water is delivered directly to each household and is available on demand. Normally open actuators ensure safety of use; even in the event of a power outage or if the main power is accidentally turned off while residents are away, heating remains uninterrupted, preventing pipes from freezing and resulting in property damage.

2. In southern regions with individual household heating—including those with centralized heating systems but where wall-mounted boilers or heat pumps serve as the heat source—normally closed electric heating actuators should be used.

Reason: Heating areas with independent heat sources are generally located in southern regions, where the climate is relatively warm. Residents use electric heating actuators and thermostats primarily for time-of-use heating to save on gas or electricity. Normally closed actuators ensure energy efficiency while preventing the heat source from igniting automatically, which would waste energy.
