Our hot water is not scheduled to come on until 6am. Although at 9pm our radiator in bathroom(comes on when hot water is on) is very hot. Checked app and control and says water not on until 6...why is the boiler working when not scheduled?
Hi there! I'm sorry to hear about this situation, but I'll do my best to help you. This might be happening because of various reasons. Bacteria Prevention mode will activate if the domestic water hasn’t been heated for at least two consecutive hours in the last 48 hours. If you want to turn this feature off, you can go to Settings on the thermostat itself and then to Equipment > Continue > Bacteria Prevention and deactivate it. You can find more about How the Nest thermostat helps prevent Legionella bacteria, by reading the article.
