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.
