@matthannon do bear in mind they’re a bad idea (TRVs in general with the exception of bedrooms) with an Air to Water #A2W based (i.e. radiator/UFH based) #HeatPump so shouldn’t be used, nor pushed.

An open circuit that doesn’t restrict flow is very very important to get the efficiency levels they’re rated & good for.

Take a look at #HeatGeek (Adam Chapman) @petereastern , @kenbone , @stevewebster56 , Nathan Van Gambling for references to this

@matthannon @petereastern @kenbone @stevewebster56

I had the Honeywell EvoHome smart radiator setup on all radiators prior to this summer when I got my Daikin #HeatPump installed by Octopus 🐙 Energy.

They also agree with the no smart TRV (or set all to max) approach & instead balance the radiators and UFH.

All controls (incl. smart TRVs) are now gone, with the system running brilliantly efficiently on pure weather compensation control only.

@matthannon @petereastern @kenbone @stevewebster56 have you considered doing an episode for #LocalZeroPod to aid people with best practices for #HeatPump ?

I see you’ve had Nathan van Gambling and Adam Chapman on before, but would be worth having even a segment on this.

Remember: #HeatPump efficiency (from being able to lower flow temperature from say installing more or bigger radiators) is equivalent of other energy saving measures. Subtle.
