I am always bemused by the prevalent attitude towards "smart" heating controls among installers and the general population along the lines of "if it doesn't save me money on my gas bill what's the point ?"
As if saving money were the only reason you might want to improve your heating system. Hence when a study comes along and says TPI or zoning "only saves x few percent" everyone concludes it isn't worth it. (Certainly not in return on investment terms)
For me Evohome was never about saving money, it was always about better, smoother, more accurate regulation of temperature in rooms, (I hate constantly having to manually tweak TRV's because the room is too hot then too cold, then too hot etc) fully independent control of rooms, (I like being able to turn on a bedroom at night without the hallway blasting downstairs etc) being able to schedule different rooms independently, and remote control of heating when away from home.
If there is any gas savings, great, but that is a bonus not what I bought the system for. There is no way that the small savings that might be offered from zoning or TPI would pay back the cost of the hardware, unless you kept the system for an unreasonably long time, until it is well past its use by date and no longer supported.
