WiFi room thermostats

A very interesting article and can see how it would help many a person but I find keeping it simple means 99% of the time any faults are fixed in one visit, now once we upscale the complexities the bill increases and the repair time greatly increase as there's that much to read and program up.

Oh there’s no question simple On/Off controls are simple.  However, with modulating condensing gas boilers the Skool of Thought has changed & for economic reasons Home temperatures are more controllable with systems like Opentherm - a point-to-point digital protocol system.  These systems can monitor the ambient temperature better & romp up or down the boiler according to the heating requirements.

Modern Systems in well insulated homes use these controls & unlike the old ‘two on/off’ Periods per day, the heating is on a ‘set back’ temperature & is never really off.  The system just ‘ticks over’ all day & night.

Also, there’s an increasing move for condensing boilers to be Hot Water Priority, this means that the high temperature requirement of a cylinder can be achieved quickly(especially with a quick recovery coil) & the CH then run at a lower temperature, therefore having the boiler in condensing mode more often.

Well it is an option and if you post the instructions up for both I or other members could study it more closely before saying yes, but you quiet often have limited terminal space and toget two conductors into many of the modern devices is hopeless task.

Just a DIyer but Id think if the hot waters via a hot water cylinder like mine then there's a fair reservoir of hot water built up so unless they are going to be using a lot extra what suits you HW wise should cover their needs ?
