What Are Electric Heaters?
Electric heaters convert electrical energy into heat, making them a versatile choice for residential, commercial & industrial applications. They use resistive heating elements that warm up when electricity passes through them, transferring heat to the surrounding space or medium.
Common types of electric heaters include:
-
Baseboard heaters – Installed along walls for zoned heating in homes and offices.
-
Fan-forced heaters – Use a fan to distribute warm air quickly in workshops or small rooms.
-
Radiant heaters – Provide focused heat in open areas or where silent operation is needed.
-
Immersion & process heaters – Used in tanks, vessels, and industrial systems to heat liquids or gases.
Because these heaters generate heat quickly and are easy to install, they are widely used for both permanent installations and supplemental heating needs. However, electric heaters require reliable temperature control & safety limit devices to prevent overheating and improve energy efficiency—making thermostats a critical component.
Thermostat Options for Electric Heaters
Tempro Line Voltage Thermostats – Control Electric Heaters
Explore Tempro Thermostats for Electric Heaters →
Tempro line voltage thermostats provide direct temperature control for residential & commercial electric heaters. These thermostats switch power on and off without additional transformers or relays.
How They Work
-
Electric heater wires connect to terminals R & B.
-
When room temperature falls below the user-selected setpoint, contacts close and power flows to the heater.
-
When temperature rises to the control differential (±2°F), contacts open and the heater shuts off.
Applications include baseboard heaters, fan-forced wall heaters, ceiling-mounted radiant heaters & space heaters in garages, workshops & offices.
Snap Disc Thermostats – Limit Electric Heaters
Explore Snap Disc Thermostats for Electric Heaters →
Snap disc thermostats serve as high-limit switches, protecting electric heaters from overheating. They use a bimetal disc to mechanically open contacts when the set temperature is exceeded, shutting off the heating element until safe temperatures are restored.
Applications
-
Mounted near the heating element in the airstream
-
Used as high-limit cutoffs to meet safety codes & prevent component damage
Senasys offers a wide range of snap disc thermostats, including automatic reset & manual reset options, with various mounting brackets, terminal styles & temperature settings.
Bulb & Capillary Thermostats – Control & Limit with Remote Sensing
Explore Bulb & Capillary Thermostats for Electric Heaters →
Bulb & capillary thermostats provide precise temperature control & high-limit protection where remote sensing is required. The sensing bulb can be installed directly in the heated zone while the switching mechanism is positioned in a cooler, accessible location.
Applications
-
Duct heaters in air handling systems
-
Immersion heaters for water, oil or chemical solutions
-
Tank & vessel heaters for fluid control
-
Process heaters for industrial manufacturing
These thermostats support flexible mounting, high accuracy & documentation for certification compliance, making them ideal for OEM heater designs.
