Another reason I rely on a plug in thermostat is the energy savings. By automatically turning the heater on and off based on the room’s temperature, it prevents wasted energy and lowers my electric bill. It’s a simple way to be more eco-friendly while still staying cozy during colder months.

My Buying Guides on Plug In Thermostat For Heater
When I first started looking for a plug in thermostat for my heater, I quickly realized there are quite a few options and features to consider. To help you make an informed choice, I’ve put together this guide based on my own experience and research. Here’s what I focused on:
Understanding What a Plug In Thermostat Does
A plug in thermostat is a handy device that plugs directly into your wall outlet, and then you plug your heater into it. It monitors the room temperature and turns the heater on or off to maintain your desired temperature. This helps save energy and keeps your space comfortable without constantly adjusting the heater manually.
Key Features I Looked For
- Temperature Range and Accuracy: I wanted a thermostat that covers the temperature range I need—usually between 40°F and 90°F—and one that provides accurate temperature readings. Some devices offer digital displays which make it easier to see the current temp at a glance.
- Compatibility with My Heater: It’s important to check the wattage and voltage your heater requires and make sure the thermostat supports it. Overloading the thermostat can be dangerous and cause malfunction.
- Ease of Use: Since I’m not super tech-savvy, I preferred a thermostat with simple controls and clear instructions. Some models have intuitive dials or buttons, while others come with remote controls or smartphone apps.
- Safety Features: I looked for models with built-in safety features like overload protection, short-circuit protection, and fire-resistant materials to keep my home safe.
- Size and Portability: Because I use it in different rooms, a compact and lightweight design was important to me so I can easily move it around.
Types of Plug In Thermostats
- Mechanical Thermostats: These usually have a dial to set the temperature and are straightforward to use. They are often more affordable but less precise.
- Digital Thermostats: These provide more accurate temperature control and often feature LCD displays. Some even have programmable schedules.
- Smart Thermostats: If you want remote access and advanced features, smart plug in thermostats connect to Wi-Fi and let you control your heater from your phone or through voice assistants.
My Tips for Choosing the Right Plug In Thermostat
- Check Your Heater’s Power Requirements: Make sure the thermostat you pick can handle the wattage of your heater to avoid safety risks.
- Consider Where You’ll Use It: For bedrooms or living rooms, a quiet and discreet model works best. For workshops or garages, durability might be more important.
- Read User Reviews: I found that customer feedback helps identify any common issues or standout features.
- Look for Warranty and Support: A good warranty and responsive customer service can save you a headache if anything goes wrong.
Final Thoughts
Choosing the right plug in thermostat for your heater can make a big difference in comfort and energy savings. By focusing on compatibility, ease of use, and safety, I found a device that works perfectly for my needs. I hope my guide helps you find the best thermostat to keep your space warm and cozy!
