OpenTherm and what E-Top Openthem thermostats can do with it

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 at the same time.

This is important because many older boilers that don’t support OpenTherm have simple on or off controls. When they're on, they will always heat the water used to warm your home to the same preset temperature, which isn’t always the most efficient way to keep you comfortable.

However, newer boilers allow opentherm thermostats to tell them when to adjust their heating water temperature and how high to set it. The boiler will use more or less gas, as appropriate, to reach the water temperature set by the thermostat.

Here E-top provides three type opentherm boiler thermostats.
