6 Best Boiler Thermostats – Smart, WiFi Thermostats For Boilers

Oct 24,2025

In the USA, about 90% of homes are powered by a central heating/cooling system like a central furnace or a boiler or a heat pump based system. We write about boiler thermostats in this guide, which are thermostats for controlling central boiler units. A boiler is basically a specially designed water heater – which distributes heat through hot water, while systems like a central furnace distribute heat through the warm air. Water is heated in a special chamber of the boiler (which is usually powered by gas or fuel oil) and is then distributed to different rooms of the home via radiators or other heat distribution systems installed. A boiler thermostat helps in controlling the boiler operation, thus maintaining a proper set temperature inside the home.


As I noted above, there are different types of boiler systems like gas-fired boiler, steam boiler, and fuel oil-based boiler. Out of these 3 types, gas-fired boiler is the most common one in USA, just like the central furnace-based heating systems. You may find steam boilers in some older home constructions, but they are being replaced eventually. Fuel oil based boilers are not used in US homes due to many reasons like foul smell, and efficiency problems. All thermostat models reviewed below are suited to use as a gas boiler thermostat – be it a smart thermostat or a WiFi/Wireless boiler thermostat model or just a normal programmable thermostat variant.


We are here to help you learn more about boiler thermostat models, to find the right one that best fits your boiler heating system.
