How to Choose an Electric Actuator
May 15, 2026
1. In areas with centralized heating, use normally open electric actuators. Reason: Centralized heating systems are typically found in northern regions, where the climate is colder. Residents primarily use electric actuators and thermostats to save on heating costs in communities with metered heating billing. 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 away, heating remains uninterrupted, preventing pipes from freezing and resulting in property damage.
2. In southern regions with individual heating systems—including those with centralized heating but where wall-mounted boilers or heat pumps serve as the heat source—normally closed electric heating actuators are used. Reason: Areas with individual heat sources are generally located in the south, where the climate is warmer. Residents use electric heating actuators and thermostats primarily for time-based heating to save on gas or electricity. Normally closed actuators ensure energy efficiency while preventing the heat source from igniting automatically, thereby avoiding energy waste.
