What are your ultimate aims for the system? Do you want individual room control or just basic 1 or two zones plus hot water?
I’ve no experience of Hive so cannot comment on it’s abilities, but have used/installed Nest and Evo (a few hundreds of Evo).
With Nest, in my opinion, unless you are flooding the house with Nest sensors (stats, Protect fire alarms etc) then the self adapting occupation is not that useful as it’s not going to have enough feedback to genuinely reflect your real usage in the house, so you’ll probably end up using normal schedules most of the time or manual adjustments for non-schedule events (just like any other smart system). Best does have useful integration with its smoke alarms though, so automatically switches off boiler demand if there is a CO alarm activation for example. However it does not lend itself easily to full room zoning, and having to power the stat (and maybe use wired feedback to the Heat Link) can limit retro-fit options.
Evo is different to most systems in that it is a truly modular system with most common applications covered - wireless TRV controllers, wireless room sensor options, underfloor heating manifold controllers, hot water kit including HWS sensor, single relay modules that can be configured for a number of uses etc. So it can be installed as a simple 1 or 2 zone heating controller with or without hot water, or be fully room zoned irrespective of heating type. However this also makes it more expensive than Hive and Nest too.
You might also want to consider Heatmiser Neo, as they have both wired and wireless options that may be suitable if you only want basic zone valve level control (rather than individual room zoning).
In terms of operation they all work in a similar fashion so will achieve similar levels of comfort/accuracy of temperature control. Their apps are very different, and the setting up/configuration and backup/suport are also different (in particular, Evo is seen as a pro-installer product, so tech support to end users/DIY installers is limited), so you may want to download the apps first and try them out in demo mode. |
