I have a wireless thermostat which gives me a option of hot water control. I have a combi boiler and, as such, I do not use this setting. Its would be great if I could remove this from the Tado Home Screen.
Check if your combi boiler has an eco/comfort mode. It’s a feature where the boiler maintains a small reservoir of hot water by periodically firing up to heat the water in the heat exchanger. When someone turns on the hot tap they will get hot water quicker when comfort mode is on. The Tado app gives timed control of this feature - no point in pre-heating hot water during the night.
