sorted byIt has a few advantages over other systems:
- it's (often quite a bit) cheaper - the radiator thermostats are often available for £35 each
- there's no subscription (there's an optional one-off payment to get more insights by linking to your smart meter)
- you can add additional room thermostats to override the radiator thermostats (this was a big one for me in my previous place - the radiators weren't positioned well [behind furniture etc.], so being able to have the temperature monitored from elsewhere in the room was a *huge* advantage - as far as I am aware other systems cannot do this).
- they've recently added support for electric wall heating and underfloor hearing (though apparently these need 'professional' installation for some reason)
- no separate hub (unlike Hive)
- hardware isn't locked to your account (looking at you Hive)
There are disadvantages as well:
- radiator thermostats don't have a display, and you can only boost or lower them by 2º directly from the thermostat (you can set them to a specific temperature from the app, though honestly for me a 2º boost is perfectly sufficient for rare occasions I need to set it manually)
- need to get the right model for your boiler - the standard combi boiler model *only* works with combi boilers, if you need hot water control you need the conventional boiler model, and if you already have zoned heating (with two separate radiator circuits) you need the three channel model (that's not easy to find)
- limited learning capabilities, everything is schedule based (it will learn how long it takes for the radiator to heat up to the desired temperature, but it's still working from the schedule), so unlike Nest that figures out what you want over time, you do need to set up schedules yourself (each room can be on it's own schedule). Hive is pretty much the same - not sure about tado
- no AC control (tado can do this, and I think Nest can as well)
- no wider ecosystem (at least in the UK) - Hive also offers smart bulbs, plugs and other devices. Wiser does have smart plugs, but they are quite expensive (they are recommended by Wiser as signal repeaters if you need that)
- no built in support for geofencing - you need to use something like IFTTT (then again tado charges for this I believe)
- no ethernet support, only WiFi
Beyond those, general functionality like Alexa/Google Home support is pretty standard across all the systems (edited)
There is a terrible trait of plumbers in the UK to oversize boilers. Now this can be fine if you have every radiator in the house on at the same time with the TRV fully open.
But when you start zoning and let’s say have all your spare rooms turned off, then only have the living room on etc etc then it’s highly unlikely your oversized boiler can modulate low enough to run such a smaller space.
The consequence of this is that the boiler will start cycling which is highly inefficient, expensive and damaging
The best thing to invest in is a weather compensation kit for your boiler and just leave all room radiators on (you may need to balance your system to get even temperatures throughout the house)

If you boiler is off 50% of the time ( cycling) its going to use less gas then running constantly ( the extra efficiency is not going to make up the 50%) . The efficiency of my new gas condensing boiler varies between 87.6% at high temp /high output and 97.1% at 30% output with low temperature ... So the maximum saving by not cycling in ideal conditions ( you are unlikely to get this) is 10% .
i.e. bedroom on for an hour ready for getting up then on low (12 Deg C) till a little before bedtime. Lounge on for an hour in the morning then low till evening, 2 other rooms are on low during the day and then we can boost them from our phones when we are going to use the rooms. So we only heat the rooms we need when we need them.
