Boilers with OpenTherm control bus

prices on 29 models

OpenTherm

— it is a fairly simple standard with modest functionality: it allows only a direct connection between the control and the controlled device, and it is not designed to create extensive systems. On the other hand, this bus has quite advanced capabilities for controlling heaters: in particular, it allows you to control the temperature not just by turning the boiler on/off, but by changing the power of the gas burner. This mode of operation contributes to saving fuel/energy, as well as reduces wear and increases the life of the heater. And in many cases, a system of two devices (boiler and thermostat) is quite enough for effective heating control. At the same time, the OpenTherm standard is simple and inexpensive to implement, which makes it extremely popular in modern boilers. For several reasons, it is mainly used in gas models.
