I do see the point about mini-BMS but I also see that people will not understand them. Many years ago, before I was qualified, I re-vamped my mother's heating system. TRVs in common areas, zone control valves in all rooms and bedrooms and room thermostats. The bedrooms had programmable thermostats controlled by the main programmer so the bedrooms could be held at a low temperature until the evening (unless they were needed for study purposes etc in which case the stat manual over-ride was used), meaning they only got a quick blast before bed time.
Problem is no one else except me could get their head around the system. Even my mother whose house it was. While my mother and I were away, a lodger took off the lockshield heads and opened the balancing valves fully in an attempt to improve heat output to that room, presumably (thus throwing the entire system out of balance).
People couldn't understand why a room wasn't heating up when the programmable stat was clearly calling for heat (because the main programmer had switched the heating off), or why a room wasn't heating up when they had switched the system on, or they would turn a thermostat up to 25 in the belief that the room would somehow reach 18°C more quickly when the stat was at 25.
Probably a mini-BMS would be more intuitive and I will be interested to hear more details.
Meanwhile, when someone has a (?) balancing issue, I cannot understand why you would recommend that they remove the TRVs. They are not looking for a new system: they are trying to make the one they have work to its original spec.
