Gas and wood-burning heating appliances need accurate thermal control to run efficiently and safely. One key component that makes this possible is the temperature switch used in wood stove setups, specifically the SPDT snap disc thermostat. These switches manage heat output and provide alerts that help reduce energy use and improve user control.

How These Switches Work in Wood Stove Systems
SPDT (Single Pole Double Throw) snap disc switches serve two functions in one unit. In these heating systems, they handle fan control and provide a signal when temperatures fall. When the stove area reaches 83°F, the fan turns on to move warm air into the room. When temperatures drop below 65°F, the switch shuts off the fan and turns on an alarm light, letting users know it’s time to reload the stove.
These switches power only one output at a time. That keeps the blower and alert system from running together, which reduces strain on the system and cuts down on power use.
Installing the Switch
The switch needs to be mounted near the secondary air tube, not inside the firebox. This lets it measure temperature changes more accurately without being damaged by direct flame. The selected on/off points match the heating pattern around the tube, not the fire itself.
Senasys’ 3/4” epoxy-sealed snap disc thermostats feature an automatic reset and IP68-rated build, making them a fit for high-heat, rugged environments. These models handle up to 15 amps at 120 VAC, giving them the strength needed for most heating applications.
What Sets Senasys Apart
We build our temperature switches in the U.S., which shortens delivery times and keeps our production quality consistent. Each switch goes through a full round of tests before it ships.
We also offer a wide range of custom options, from different wire lengths and mounting brackets to custom switch points. This gives manufacturers more flexibility in matching the part to the design of their heating systems.
Energy Savings and Better Heating Control
Many heating setups keep the blower running too long because they lack a smart switching system. Our SPDT snap disc switch stops that waste by turning the fan off when heat levels drop. When it gets cooler, the alarm light gives the user a heads-up to stoke the fire.
This setup saves energy and keeps the home more comfortable. Homeowners can better manage room heat, and engineers can simplify wiring and reduce the number of parts needed.
Adding a temperature switch to a wood stove setup improves heating control, lowers energy use, and gives the user a better experience. With our strong build quality, fast delivery, and custom features, Senasys helps heating equipment manufacturers and system designers deliver reliable, efficient products.
