What tado items do I need for my system?
My existing boiler arrangement has 2 zone valves controlled by 2 wired thermostats. One zone does the ground floor, whilst the second zone controls the top 2 floors. My current controller also controls the hot water.
The reason I want to move to smart thermostats is because the thermostat for the top two floors is mounted in the master bedroom and the top floor remains cold whilst the master bedroom is up to temperature and turns off that zone. Can someone give me a hint as to what I need to purchase to take control of the heating and hotwater so I can keep the heating on in the top floor even if the master is up to temperature. I am guessing, 2 stats to replace the existing ones and maybe some smart radiator valves for the radiators up stairs. But I am not sure about the base unit for the boiler demand and zone valves.
