What is OpenTherm thermostat?
OpenTherm is a language that compatible thermostats and heating systems can use to talk to each other, enabling thermostats to control heating and domestic hot water systems.
Is OpenTherm any good?
Yes, hand on heart, the right OpenTherm enabled control used with the right Opentherm enabled boiler is 100% worth it. The intelligence that can be utilised by controls reading the boilers data, is far more advanced than a control system with no feedback of the boiler or its surroundings.
What is the difference between on off and OpenTherm?
The standard way to control a heating system is to switch the boiler on and off at intervals with On/Off controls. OpenTherm provides more precise control on the boiler through the control of the gas valve. It allows the amount of heat provided by the boiler to be controlled to match the varying demand signal.
What is an OpenTherm device?
OpenTherm is a point-to-point communication system and connects gas central heating (condensing) boilers with room thermostats. The OpenTherm ‘protocol’ sets the rules on how the boiler and the room thermostat communicate with each other.
How can I tell if my boiler is OpenTherm?

What is OpenTherm bridge?
The Honeywell Home OpenTherm Bridge provides more precise control on the boiler through the control of control setpoint (temperature of the water as it leaves the boiler). It allows the amount of heat provided by the boiler to be controlled to match the varying demand signal from the room sensor(s).
Is OpenTherm more efficient?
One of the main benefits of OpenTherm modulation is more stable and accurate control of the room temperature, even when compared with On/Off load compensation controls. Note: May or may not overshoot but will have a stable control (Very minor fluctuations – but better than On/Off load compensation).

How does OpenTherm work with smart thermostat?
With OpenTherm, you get a digital interface to the boiler that allows your smart thermostat to change the temperature of the water used for the heating. This is called modulation. As most smart thermostats understand how long your home takes to warm up, they can measure the heat required to get your house up to temperature.
What to do if your heating system is not compatible with OpenTherm?
If your boiler isn’t easily accessible or you can’t find the OpenTherm logo, this doesn’t mean that your boiler isn’t compatible. Contact your heating system’s manufacturer and ask about your model to make sure. If you still don’t know whether or not your system is OpenTherm compatible, check with a Nest Pro.
How much energy savings can you get with OpenTherm?

What can you do with a Nest Thermostat?
Learn how to tell which Nest thermostat model you have. With OpenTherm, the Nest thermostats listed above can control both your boiler’s domestic hot water temperature, as well as the temperature of the water used to heat your home.
