with Evesta
keep your household's energy use under control
The hot water boiler is one of the largest electricity consumers in any home, if not the biggest. Running around the clock, every day of the year, it makes energy optimization especially important. Replacing it with a modern unit can be costly and time-consuming, but with Evesta you can make even older devices smart. And when you’re away, the app makes it easy to monitor and adjust your hot water boiler’s operation from anywhere.
caladrius s
The Evesta Caladrius S three-phase switch, mounted on a DIN rail, controls whether your hot water boiler receives power. This means any hot water boiler can be made smart — no matter how old it is. With the Evesta app, you can easily set when your hot water boiler uses electricity, for example only during the three cheapest hours of the day!
Caladrius thermostats
Evesta’s Caladrius thermostats — the T3 and T1 — operate much like the Caladrius S three-phase switch. The key difference, when connected to a hot water boiler, is that if a sensor can be installed in the tank, you can optimize water heating based on temperature. For example, in the Evesta app you can set the water temperature to stay at a minimum of 60°C, while allowing it to heat up to 80°C during cheaper electricity hours.
