The thermostat is a very important switch in the central heating system, it is opened/closed by changes in room temperature. So, if you want to adjust your central heating and hot water temperature, you need a boiler thermostat.   At home, boilers are the main heat source. It can be a component of a public or home heating system. It can provide the heat needed to maintain a pleasant home temperature. Every winter, it consumes a significant portion of the household budget, so investing in thermostats, heating control equipment is very wise. It reduces the energy consumption of the boiler and saves bills. Several boiler thermostats are available on the market for heating regulation equipment. They vary on a variety of costs, functions, and regulation levels. Some of them are: Mechanical thermostat: Mechanical boiler thermostats are the traditional and standard type of thermostat, typically found mounted to an internal wall.  Mechanical gas boiler thermostats help to regulate the temperature using two pieces of different metals laminated together to form a bimetallic strip. The strip is a part of the electrical circuit that switches the heating system on when completed and switches it off when broken. Programmable thermostat:   Programmable digital thermostat is a more advanced boiler thermostat. Programmable thermostat adjusts the temperature by changing the operation of the boiler. It also allows you to customize the set temperature based on the time of day. You can set various set temperatures for different time periods of the day. As thermostat factory, e-top provide programmable thermostats as.   a.     Battery wired programmable boiler thermostat.   b.     230Vac wall mounted programmable LCD boiler thermostat C. Battery wireless programmable boiler thermostat d. Programmable wireless heating & hot water combi boiler thermostat    Smart programmable thermostats Smart programmable thermostats provide the same benefits as mechanical thermostats and programmable thermostats. It helps to regulate and program temperature, while also upgrades and introduces new features. It allows the user to control the temperature setting using an app remotely. You can change the temperature or control the temperature with the app. This can be an excellent step to a smart home integration.   E-top smart thermostat use smart life app, mainly two types. a.     Zigbee smart thermostat b.     Wifi intelligent smart thermostat.
