Best Smart Thermostat 2018: Smart Heating Systems


Want more help deciding which is best for you? Read our buying advice for the best smart thermostat

1. Honeywell Evohome

Evohome is the best smart heating system we’ve tested. However, it isn’t perfect and it’s also very expensive, or can be. But if you value convenience and comfort above saving money in the short term, it’s the one to buy.

2. Genius

Heat Genius is very good at a very useful thing. It is easy to use and efficient, and over time it will save you the cost of installation. And it is fairly priced. How long Heat Genius takes to pay for itself will depend on your circumstances, and it may be that dropping £800 to £1,200 or more is too much of a long-term investment for you. But it is a great product, and if you are looking to install in your home a zoned smart heating system, we are happy to recommend Heat Genius – not least because of its potential as a true smart home network for your house.

3. Drayton Wiser Multi-Zone
Drayton Wiser Multi-Zone

Wiser is easy to install and easy to use. It doesn’t have lots of advanced features but is a lot cheaper than some of its rivals, including Tado and Netatmo.
The app is great, too, and several features have been added since launch including Alexa and IFTTT.

4. Nest Learning Thermostat (3rd Generation)
Nest Learning Thermostat (3rd Generation)

Being reliable, well-designed and easy to use, the Nest thermostat is a great choice. It doesn’t have the array of accessories and compatibility of systems such as Honeywell Evohome, but you can buy separate smart TRVs to control radiators without changing your plumbing. The Nest Protect smoke and carbon monoxide alarm also works with the thermostat, as does the Nest Cam camera. The 3rd generation can also control your hot water, making it even better, and the latest app update means your phone can tell it when you’ve gone out.

5. Hive Active Heating 2
Hive Active Heating 2

The Hive Active Heating system is a great upgrade for anyone that wants or needs the ability to be able to control their heating remotely. The recent addition of multizone support is also good, and the ability to boost heating and hot water is a great feature. This second iteration of Hive is a giant leap forward from the solid (but somewhat dull) first-generation product. The interfaces of both the app and thermostat are intuitive and quick to use. There are clearly energy savings which Hive can help you make and you can quickly recoup your expenditure if you’re conservative with your temperatures and schedule. And it is easy to add Hive Active Light as well as smart plugs and switches, too.

6. Tado Smart Thermostat
Tado Smart Thermostat

Tado is definitely saving me money by being smart about exactly when and to what temperature my hime is being heated. It’s clear that having control over a house’s heating determined by who is in the house and who isn’t makes a lot of sense. Tado is the best smart thermostat at this as its presence detection simply follows you and your smartphone via GPS, and turns the heating up or down as you get further away or nearer home. Most of us just set the timer and only go back to the boiler to flick it on or off when we get too hot or cold. Being able to control this (wherever you are) via an app on your phone is a much more intelligent way to control your heating and energy costs. The initial cost isn’t cheap, but there is a money-back monthly payment option, and you should start saving on your heating bills within a few days.

7. Nest Thermostat E
Nest Thermostat E

The Nest E is a great smart thermostat that’s comfortably among the most stylish and easy to use on the market, but as it stands in the UK, there’s not much reason to opt for the E over the existing 3rd gen Nest, which has some extra functionality for a similar price.
The E is slightly easier to install by yourself, but still requires dealing with screws, fuses, and wiring. If you’re so worried about picking up a screwdriver that you’ll pay for installation either way, then you might as well buy the 3rd gen. If you’re so confident that you know you could install either, buy the 3rd gen too. The only real reason to buy the E is if you’re confident enough in DIY to install the E, but not enough to try for the full Nest.
It’s a different story in the US though – a bigger price gap makes the E an easy recommendation if you’re in the States, as there it offers all of the most important features of the third generation Nest, together with design improvements, for a significantly lower price.

8. Netatmo Smart Thermostat
Netatmo Smart Thermostat
Netatmo’s thermostat is relatively basic, lacking any kind of presence detection, but it works well and is one of the cheaper options. The display lets you adjust temperature and nothing else, so you’ll need a compatible phone or tablet to get the most from the system.

9. Devolo Home Control Radiator Thermostat
Devolo Home Control Radiator Thermostat

So, what do we think of the Devolo home control system as a smart heating system? Even though it was designed with the whole home in mind, the heating accessories make the Devolo system a great smart heating system, although not as invasive as the likes of Hive and Nest. Unlike those, you don’t need an engineer to install it – in fact, it only took us minutes to do it ourselves. It provides per-room temperature control, where Nest and Hive can only control the temperature of the house as a whole. However, to control the boiler you’ll need the smart thermostat as well.
The app experience lets it down a bit, but the full website more than makes up for a frustrating mobile app. Devolo’s additional accessories can turn a dumb home smart, and it can be a gradual process as all accessories are sold separately.

10. Momit Home Thermostat
Momit Home Thermostat
If you’re replacing a wired thermostat and don’t mind fixing the Momit in the same place, then installation is an absolute breeze, and a snip at under £100. It’s certainly not the most stylish and isn’t really suitable if you need to control hot water too, but for many people it will give them the remote control they need, with good presence detection and geo-location as bonuses. If you need a wireless smart thermostat you’ll need to buy the optional £29 extension box which brings the price very close to the 2nd Gen Nest (now around £130) which may be a better buy if looks are important to you, or you value the integration with the Nest Cam and Nest Protect.

Buying guide for smart thermostats
The key question is the level to which you need – or want – to make your heating smart.
Most of these systems – Hive, Nest, Netatmo and Tado – simply put a smart thermostat into the most-used room in the house or the hallway, and moderate the temperature of the whole house to match that room. For smaller houses in which most rooms are in regular use this is probably a cost-effective way of attaining the desired results. You can always turn off the radiators you don’t need to avoid heating rooms unnecessarily.
They also make it easier to set schedules and many have ‘smart’ features to make your heating more efficient and therefore save you money. For example, they can detect when no-one’s home and automatically turn off the heating.
Honeywell Evohome and Genius offer something more. One of the ways they do this is by replacing the valves on your radiators with ‘smart’ valves. They allow you to divide up your home into various zones and then offer smart heating in each zone, so your guest bedroom is heated only when required, the master bedroom is warm in the morning and at bed time, and the kitchen is hot at tea time.
Increasingly, though, other manufacturers are launching smart radiator valves, including Tado. In fact, these smart TRVs can often be used independently of the thermostat so you don’t necessarily need to buy the same brand and you can still use them with Nest, which doesn’t currently offer the valves. 
The only issue there is that you’ll need two separate apps to control your heating.
In any case, Honeywell, Genius and certain others can control more sophisticated heating systems (including underfloor heating and hot water tanks) but, of course, they are a lot more expensive. And in the UK at least, all modern houses with living space covering ground greater than 150m2 have to be built with at least two zones of heating, according to 2013 Building Regulations Part L.
So again: a well-used, modern, small house (or flat) is unlikely to need this level of sophistication, and a well-used large home may have sufficient zones plumbed in to make Nest or Hive a good solution. Just remember that you’ll need one thermostat per zone, so while it’s cheaper than fitting each radiator with a £50/$50 smart TRV, it’s still relatively expensive.
If you have a boiler and central heating you will likely be able to fit any of the systems here. Storage heaters are another matter, as we discuss in this article: Can I use a smart thermostat if I have a storage heater?
The right smart-heating system for you will be dictated by your home, your use of that home and your requirement to save money.
The good news is there is a way of making every house more efficient, comfortable and the householder more wealthy (or at least less poor). But the best way for each house will differ.
