Heat-only Thermostat For Fireplaces or Garage Heaters

Thermostats don't come much easier to install & use. These non-programmable heat only thermostats are built to Emerson's high quality standards, yet have a lovely low-quality price tag.

Emerson's 1E78-140 Thermostats pair great with a gas fireplace or a garage heater or unit heater. Features of the 1E78-140 thermostat include:

  • Residential single stage, multi-stage and heat pump applications
  • 70 Series are the perfect upgrade from mechanical thermostats
  • 70 Series will cover up wall marks left behind by most mechanical thermostats without the need for an extra wall plate
  • Fossil fuel or electric heat compatible
  • Large LCD with backlight

Don't forget, when you pair our thermostats up with a new fireplace or unit heater, you save $$$!
