In the filed of condensing boiler installation, the term 'Opentherm' is getting more trendy. Why opentherm takes an increasingly important role in a modern underfloor heating system?The following tips will help you understand the basics of Opentherm heating system and opentherm modulating heating control. The opentherm way to control boiler , not cycling your boiler on and off periodically, it adjusts boiler heating water flow temperature precisely. So what benefits can we get if we are using opentherm thermostat?   1. Lower gas fuel bills   As russian-ukraine war, gas fuel price soars by 50% compared to the previous, saving more energy becomes more important mission in the room heating industry. A SmartTherm thermostat utilizes PI algorithm to calculate boiler water set point and adjusts the heating water temperature according to the desired set point. This not only keeps the rooms at the correct temperature, but it also increases the efficiency of the boiler by allowing it to run at lower flow temperatures for a longer period of time. As a result, the boiler stays condensing for longer.   2. Extend boiler lifespan   By allowing boilers to run at a slower rate for an extended period of time, they are less likely to damage the appliance than they would be if they were constantly turning on and off. This means boiler is able to work in optimal performance and reducing more wear and tear.   3. Enhance boiler troubleshooting   ETOP opentherm wifi thermostat offers direct visual displays about the boiler status and error codes, which helps boiler installers and repairers gain more information about the fault reason. Besides the thermostat screen, ETOP thermostat also can do phone app remote checking and remote control. Opentherm provides more advanced boiler monitoring and efficiency control and improvement in the room underfloor heating system and smart thermostat manufacturing technology.
