Why NOT to Fit Smart Radiator Thermostats to ALL Your Radiators. Pros & Cons, Best Way to Fit Them

[@curranhouse]

On the downstairs toilet / cloakroom. Cant you wire the smart TRV in series with whatever boiler timer / nest / hive etc you use? This way if the radiator calls for heat but you haven't a schedule for the boiler it is blocked. :) It needs boiler to be one and scheduled and the TRV to be active for a call for heat to take place,

Retrofit only on a cleaned or necessarily Power flushed system otherwise valve body may lock up leading to cold Rads and expensive drain downs

Good video Mark. I fitted Tado smart thermostats to all my radiators bar the hallway and I've had all the issues you've mentioned. And I'm pretty sure my 12 year old Worcester Bosch combi boiler doesn't appreciate so many radiators shutting off when it's running either. Where you've removed the smart thermostats from parts of your system, have you replaced these with dumb thermostatic valves?

What a waste of money all this is, just manual thermostats would do all this without the expense and trouble
