How To Find The Best Space Heater With Thermostat

Manufacturers equip space heaters with different features for different purposes. Some of the features will help make the unit more energy-efficient than others. Also, some are designed to prevent the risk of fires and overheating.

One of the features that cut across all these benefits is a thermostat. Actually, a space heater with thermostat allows you to set your desired room temperature, and it cycles on and off to maintain it.

However, space heaters come with different types of thermostats – programmable or adjustable. Therefore, we advise that you choose a space heater with a digital thermostat to avoid having to adjust the temperature yourself.

That said, if you’re unsure of which electric heater to pick, here’s a list of the best space heaters with programmable thermostats that we’ve thoroughly reviewed and tested.

Best Space Heater with Thermostat Buying Guide

Now that you know some of the best space heaters with thermostat control, let’s learn how to pick the right one for your needs.

First Things First, What is a Thermostat?

A thermostat is a device used to measure the home’s ambient temperature. Often connected to an HVAC device such as a heater or air conditioner, the main purpose of the thermostat is to continually read the current indoor temperature and compare it to the required heating/cooling value. If there’s a mismatch, the thermostat relays the information to the heater/air conditioner to initiate or stop the heating or cooling process.

How Does a Thermostat Work?

Different thermostats work in different ways. The very first home heating thermostat developed way back in the 17th century comprised a float inside a mercury thermometer. The device was then connected to a damper in a furnace. Whenever the mercury climbed to a specified level, the float caused the damper to close.

Similarly, modern thermostats apply the same mechanism. Today’s thermostats have temperature sensors that cause an electric switch to open or close depending on the degree of heat detected. When the switch opens, it breaks an electric circuit, causing heating to stop. When it closes, the circuit is completed and heating starts.

Types of Thermostats

controlling a space heater with an inbuilt thermostat

Before you go ahead to purchase your best space heater with thermostat, you also need to understand the different types of thermostats. Although most modern space heaters use programmable thermostats, there are four broad categories of thermostats; mercury contract, mechanical contract, digital, and electronic programmable.

1. Mercury contract thermostats

Mercury contract thermostats, the oldest on this list, are analog thermostats that were once the most common thermostats on home furnaces. The thermostats contain a bimetallic strip that moves up or down as the temperature increases or decreases. Consequently, the moving bimetallic strip closes or opens a glass vial contact known as an ampoule. As a result, it completes or breaks the flow of electric current.

2. Mechanical contact

Mechanical contact thermostats are pretty much similar to mercury contact thermostats except for the type of contact used. In mechanical contact thermostats, a bimetallic coil that includes a heat anticipator is usually used.

3. Digital thermostats

As you may have guessed, mercury and mechanical contact thermostats aren’t very common anymore. Space heaters, in particular, use either digital or electronic programmable thermostats. Digital thermostats use electronic controls instead of a bimetallic coil/strip to sense temperature changes. They also feature prominent digital displays, have on/off switches, and are more accurate.

4. Electronic programmable thermostats

The most advanced thermostats at the moment, however, are programmable options, especially smart models. A programmable thermostat is a digital thermostat that can take instructions for later application. You can, for instance, set the thermostat to go OFF after eight hours of heating. The thermostat for steam heat systems is a good example of programmable thermostats.

Smart thermostats go one level up. Instead of just taking instructions, they learn your habits and use the information to make smart decisions. These thermostats learn a family’s behaviours and preferences, digest the data, and use the information to self-program. Smart thermostats can also be connected to other smart home devices such as tablets, computers, and smartphones, and even controlled via Siri and Alexa.

Benefits of Using a Small Heaters with Thermostats

benfits of a space heater with thermostatNot all space heaters come with thermostats. Therefore, the reason you should consider models with a thermostat include;

  • Maintain the desired indoor temperatures: When you have a thermostat-controlled heater, temperature fluctuations become a thing of the past. Whenever indoor temperatures go below or above the set value, the thermostat instructs the heater to slow down, ramp up heat production, or go ON/OFF until the desired temperature is achieved.
  • Spend less time adjusting: The best part is that, with programmable and smart thermostats, you don’t need to worry about making adjustments yourself. The thermostat automatically adjusts heat production to keep you comfortable round the clock.
  • Increased energy efficiency: When you program your thermostat to go off when you’re away, you’re guaranteed significant energy savings. So, if you can create a heating and cooling schedule that follows your family’s routine, you’ll certainly save plenty of bucks.
  • Help out your HVAC appliances by optimizing workload: With a thermostat in place, there’s less risk of overworking the heater and other connected appliances. This can help reduce wear and tear and keep your expensive appliances operational and in top condition for a long time, further increasing savings.
  • Embrace the smart home trend: Finally, the shift to a connected world is real. If you’re a digital enthusiast, upgrading to a heater with a smart thermostat would be the way to go because the units can be connected to other smart devices in the home. This way, you can control your heating and other tasks from your smartphone, tablet, computer, or smart home devices such as Siri and Alexa.

Is Your Thermostat Working Correctly?

Thermostat malfunction is a common problem, especially in hot water baseboard thermostat. When this happens, the heater might stop working or exhibit several other malfunction signs. For example, you may find that the room temperature and the thermostat setting don’t match. Or, the heater may not shut off/turn on as programmed. Such problems probably point to a thermostat issue. If you encounter such an issue, we recommend that you contact an HVAC professional or the manufacturer.
