Hive Active Heating 2 review with multizone


Hive, Nest and others have been putting a lot of energy into a heated battle in the smart thermostat arena. We’ve already reviewed Nest, Tado, Netatmo, Devolo, Heat Genius and Honeywell EvoHome. Here we look at the latest iteration of Hive Active Heating 2 with support for multizone. See also: Best smart thermostats.

Black Friday Deal Alert: Hive Active Thermostat is reduced to just £119 over at Argos!

Historically thermostats were small, uninspiring boxes installed by a plumber, set to 21 degrees and largely forgotten. British Gas (the maker of Hive) is known for many positive things but style, until Hive 2, has never been one of them. Whichever Hive employee said “Hive needs a world class designer” and hired the external team at FuseProject (led by Yves Béhar) deserves a promotion. The Hive thermostat is one of the best-looking smart thermostats on the market – they should never be hidden; they are a piece of art and simply demand to be admired. When inactive it has a glass mirror-like surface; touching the dial illuminates the device with space-age controls. See also: Hive Active Light review.

Hive Active Heating 2 review: Price

Depending on your existing heating system you will need to buy the right number of zone controllers. It’s cheaper to self-install but realistically for most people it isn’t worth the hassle. You’ll find the single-zone kit for £249 at Hive Home.

If British Gas is your energy supplier (or are happy to switch) then look out for special offers which include heavily discounted Hive systems. Not wanting to give first-generation users the cold shoulder Hive has a very sensibly priced £99 upgrade to the new hardware, and this includes installation.

* Installation should only be undertaken by a qualified professional, Hive says.

Hive Active Heating 2 review: Who can use Hive and Hive Multizone?

Just about anyone with a boiler can have Hive installed. You don’t need to be a British Gas energy customer and it’s designed to be used with gas and LPG central heating systems and works with normal radiators as well as boiler-fired wet underfloor heating. See the Hive Compatibility list to see if yours is compatible. Until recently Hive could only manage a single heating zone and if you had a hot water cylinder it could also control its schedule.

With the addition of multizone support Hive can now easily manage larger and more complex heating systems. For the vast majority of homes it won’t be an issue but it’s important to note that Hive can currently control a maximum of three heating zones plus hot water.

If you just have one heating zone in your house then Hive can happily take control. However, a common misunderstanding is that you can improve your heating system by getting a multizone thermostat. But thermostats alone won’t make your house multizone – you need to already have valves that separately control the water flow to different areas (often this would be a downstairs and upstairs configuration). If you are very lucky you may be able to alter your plumbing and split it into zones but that can be very costly and it could take years to recoup the expense, and saving money is the main reason to have a zoned system.

You can normally tell how many zones you have by counting your existing thermostats, so two thermostats is likely two zones. There are competitors to Hive that makes an exception to the rule by using smart thermostatic values on each radiator. If you’ve got deep pockets and don’t want to re-plumb to multizone then see our review of the Honeywell Evohome or Heat Genius.

Hive Active Heating 2 review: Installation

Although it’s fairly straightforward to do a self-install (as long as you are competent with mains wiring) most people will opt for an engineer install. This is where British Gas clearly shines. Not only does it make the product, but also has the telephone support and systems to give good back up and an army of full-qualified engineers waiting to quickly and painlessly fit your system. In the unlikely event that you buy Hive with install and your system isn’t compatible then you’ll get a full refund, so there’s no risk of even a wasted call-out fee.

In advance of the booked installation we received our login details for Hive and, as the day approached, helpful automated text reminders to ensure we hadn’t forgotten the appointment. The installer turned up promptly and was very knowledgeable. He had to unwire the old main controller and then replace the valve controllers (three heating and one hot water). We had expected there would be one or two glitches or hiccups or something interesting to report… but it just went in and worked. In less than two hours the whole installation was complete, including removing the old thermostats from the walls and replacing them with the sumptuous Hive thermostats.

One of the benefits is that the thermostats communicate wirelessly and are battery powered. So you don’t have to worry about trying to locate them near a mains socket (which you do with some others, such as Nest). However, unlike Nest, each Hive thermostat needs to be installed permanently in one place and not moved around. With a ‘roving’ thermostat, you can take it with you so the temperature is always correct for the room you’re in.

There’s nearly always a risk of a bit of cosmetic damage when removing old thermostats from the walls (especially if they have been painted around) but in our case the new ones perfectly covered over the existing site. One tip is that if you aren’t 100 percent sure where you want your thermostat sited then you can easily mount it using Command Strips (enabling damage free mounting and removal – no more screw holes or redecorating). The exact size required comes in pack ‘Command 17043’.

By default the thermostat has a subtle cream surround but if you want to accessorise it to colour match (or contrast) with the wall it’s on then a range of 12 colour surrounds is available.

We were guided through setting up the app and programming the schedules. It was so intuitive it really didn’t need much explanation.

Hive Active Heating 2 review: Controlling the system

The thermostats provide easy control of your heating and water, let you set schedules, apply a heating or hot water ‘boost’, enable holiday mode and, of course, adjust the zone temperature. The interface is very well designed and large enough that the main features are very readable. Each thermostat is responsible for a single zone and one thermostat also controls the hot water. It’s a slight niggle (in multizone systems) that you can’t boost the hot water from any of the thermostats. This can get somewhat confusing as as all of them have two buttons on the top – one to boost heating the other to boost water.

Large numbers tell you the current temperature and the temperature the heating is set to. You can adjust the set temperature by simply swiping up or down on the screen at any time.

When in the Off position the system automatically goes into a frost-protection mode. If the temperature inside dips below 5 degrees, the heating will turn on to prevent pipes from freezing.

The schedule section has a 7 day, 24 hour schedule already pre-set, but you can easily tweak this to suit your lifestyle. This is possible via the thermostat, but more fun with the web app’s large, colourful and easy to understand controls.

The thermostats are good enough that they could be installed in a house and used very happily as the sole control system. Most people, though, will want to install the app on their phone.

The Hive app makes using your heating system enjoyable (almost fun) and aims to save money. It’s available for Android and iOS. The rumoured Windows Phone app has not materialised: owners will have to use the web app on their phone’s browser.

You can also use the Hive website from a PC or laptop:

You can manage your Hive devices from the website as well. The app will show you whether the hub, receiver and thermostat are connected to each other, their signal strength and their power or battery status.

Wherever you are (as long as you have internet connection) you can tweak your heating settings. However, our testers commented that prior to having Hive installed, if they felt chilly while watching TV they often pulled on a blanket but now they just instantly boost the heating from the sofa. In fact, where before only one person in the household knew how to program the heating controller, now everyone can tweak it at will. In a situation where previously the house was permanently set to an eco-friendly 19 degrees the introduction of any smart thermostat has the potential to increase the bills. In reality most people will see real cost savings which, over time, should more than cover the purchase and installation cost.

Another benefit of the app is that you could help out senior relatives (which also have Hive installed) by monitoring the settings remotely and setting up alerts instantly informing you if they get too cold. You can set-up a PIN lock which will prevent others, for example kids which share your smartphone, from changing the Hive’s settings.

It’s worth clarifying that Hive is a schedule-based heating system. It doesn’t try to second guess when you might want your heating turned on based upon your recent activity. This has some benefits as the user knows what to expect.

Users of some other smart systems which do ‘intelligently’ work out your schedules have reported unpredictable behaviour. Being multizone enables the heating of only the relevant zones (thereby saving you money). So the bedrooms might only heat late in the evening and the early morning, whereas a lounge zone might be on in the evenings. We’d like to see an option to enable some flexibility in the schedule where you can set it to have the room at 21 degrees from a set time until an off time. The system could then learn how long it takes to heat each zone and, taking into consideration the external temperature, adjust on and off times to maintain a temperature across your set time period. So if you want the heating at 21 degrees until 11pm the boiler could turn off at 10.30pm. Other systems already support this and we like it.

However, Hive can make use of your phone’s GPS to monitor where you are and alert you to turn off and on the heating as you leave and return. Ideally, we’d like to see this automated. You can change the distance of these ‘Trigger areas’.

You can also set up notifications which will alert you when the temperature reaches a specified level.

If you don’t have a smartphone, or it isn’t an iPhone or Android, then you can enable Text control, which allows the system to be controlled by sending a text message.

Hive Active Heating review

Holiday Mode will automatically lower the temperature in your home for the time you are away, and it will increase it back to your normally set temperature just before you arrive back. All you need to do is simply set the dates you are leaving and coming back.

 Hive Active Heating 2 review: Smart home accessories and sensors

Hive aims to be something much bigger than just your heating system. There’s a range of smart accessories that can be controlled via the Hive app. The first products available are the Window/Door Sensor (£29), Hive Active Plug (£39) and Hive Motion Sensor (£29). There are also sensor packs available on the website. These are great additions to the system and further add to Hive’s mass user appeal. Once available for testing we will update this review.

Hive Active Heating 2 review: Future additions

One product missing from the mix is a security camera. Hive has already said it won’t produce its own as there are already plenty of cameras available. And we’ve already seen a Samsung camera hooked up to a Hive installation and had expected a selection of third-party models to be supported. However, currently, you can’t monitor your own camera’s video feed via the Hive app.

Without doubt Hive is a great hardware platform to extend and build on. Many of the new features will be free updates to the apps. Likely they will provide smarter use of location services, provide more data on your boiler usage/heat graphs and improve the general user experience. One of the confirmed updates is support for IFTTT (If This Then That). This will enable events on other IFTTT compatible devices to influence each other. So at the end of the evening when you turn off your Philips Hue lights in the lounge it can automatically turn off the heating in the relevant zone. Combined with their new smart home products it’s clear Hive aims to be something so much more than just smart heating.

Hive Active Heating 2 review:Security and bugs

As with anything you plug in to the Internet of Things there are potential security flaws and the possibility of a bug rendering your heating system out of control. We’re pleased to report that we haven’t experienced any problems with Hive. But this isn’t purely theoretical, at the start of 2016 a software bug in Nest left many users shivering in the cold and without heating until a fix was announced. There have also been several demonstrations of hacking Nest thermostats but so far all have required an initial physical access to the device. No smart thermostat can guarantee to be immune from such problems but it wouldn’t deter us from recommending a reputable system like Hive.
