Hot water temperature monitor via extension kit
My heating system is the hot water storage type where a larger tank is used to store hot water for heating the radiators and hot water supplied via a heat exchanger. The tank is heated by a solar panel on the roof and a wood burning stove. Backup heating is via a gas boiler, which is controlled by Tado. It would be good if the temperature of my hot water tank could be monitored via the extension box and the temperature could be used to control the boiler, rather than the simple hot water on/off.
