Baseboard Heater Thermostat – Ultimate Buying Guide with Reviews

You have got lots of choices in thermostats, especially when the product is for your living room or a general purpose room. But when it comes to choosing a baseboard heater thermostat, you don’t have lots of choices available at hand. One primary reason is the high-end models in thermostats do not support baseboard usage. Most of the high-end thermostat models are incompatible to be used as a baseboard heater thermostat. So what do you do? There are thermostats specially designed to be used as baseboard heater thermostats. And we are reviewing the best models out there in the market here.

The primary reason to buy and install a thermostat in your home is to cut down energy bills and save money. In fact, investing in the right thermostat is the best way to save energy bills. The money invested in a thermostat will be regained within a few months of installation. Before getting to the reviews section lets first see how to choose the right baseboard heater thermostat for your home.

Criteria to Choose the right Baseboard Heater Thermostat

Line Voltage or Low Voltage  – A line voltage system uses direct line voltage unlike the newer models (which uses a low voltage like 24 volts). Line voltage type thermostats are used in older homes and constructions especially with the baseboard heaters and electric heaters. The power wires are thicker and they run on 120 volts or 240 volts.

Single Pole or Double Pole – A single pole thermostat connects to the electric mains via 2 wires. You can not shut the power to a single pole thermostat. As an alternative method (to shut power), you can set a very low temperature in the thermostat setting to prevent heat coming up to the room. Double pole thermostat connects to the electric mains via 4 wires. It is possible to shut power to the double pole thermostat system at any desired time. So double pole has an advantage over single pole.

Mechanical or Electronic – A mechanical thermostat operates with two bonded metals which bend as temperature changes. The switche will turn ON/OFF as the bonded metal bends towards it. Mechanical thermostats lack efficiency and they waste a lot of energy compared to electronic models. The only advantage of mechanical thermostat is its low price. Electronic thermostats come with high precision temperature sensors and fast switching. They sense room temperature and turn ON/OFF the system accordingly. Electronic models are highly effeicient and they save energy. The higher price you pay for an electronic model can be regained within a few months of installation.

Programmable or Non-Programmable – The primary difference between the two is that a programmable model can be programmed for 7 days in different combinations like 5-2, 2-2-1, 7 etc. Programmable thermostats adjust itself according to the program. For example, some models have “vacation mode” and if this mode is set, the thermostat will adjust itself and save a lot of energy bills (in vacation mode they work only minimal time preventing freeze). Nonprogrammable models come at a lesser price but they dont have programming capabilities.
