What’s the Honeywell Evohome?
When Honeywell Evohome introduced a couple of years again, the device used to be probably the most robust multiroom heating device to be had. Speedy-forward a couple of years, and it stays in the similar place.
Whilst maximum heating programs get started with a single-zone thermostat and will let you construct out multiroom keep an eye on, Evohome is designed with multiroom in thoughts. As such, the device is costlier than a lot of the contest, however the trade-off is definitely value it in the event you’re after high-quality keep an eye on.
With a devoted heating keep an eye on panel and strengthen for the whole lot from unmarried radiator valves to underfloor heating programs, Evohome is among the maximum versatile sensible heating programs round. It lacks some options I’d be expecting – together with geolocation – and the is somewhat clunky-looking, however a lot of this may also be forgiven.

Honeywell Evohome – Design and set up
At its most simple, Honeywell Evohome calls for the Wi-Fi controller and the boiler relay. Relying for your boiler, you’ll both want the equipment with the usual on/off relay, or the OpenTherm Bridge, which gives modulating heating keep an eye on. The latter is the most suitable choice in case your boiler helps it, because you’ll building up your power financial savings consequently (see, What’s OpenTherm?).
An extra relay will probably be essential if you wish to have Evohome to keep an eye on your scorching water device as smartly. At this level, the heating device can perform as any outdated sensible thermostat would, controlling your heating the usage of the temperature sensor within the controller.
For multiroom keep an eye on, you wish to have to begin including different elements to the fold. For radiators, you’ll want the HR92UK radiator valve (£59.99 every, even supposing you’ll get a cut price if you are going to buy in bulk). Those valves substitute your current radiator TRVs, offering particular person keep an eye on over a radiator’s temperature. Those screw into position and are simple to suit. Adapter rings are to be had for different-sized screw threads.
You’ll be able to upload a couple of HR92UK gadgets into an Evohome room, which is at hand for spaces with multiple radiator. The HR92UK isn’t the prettiest of gadgets and appears somewhat plasticky. Then again, the neat LCD display screen and twist dial on the most sensible supply much more keep an eye on than rival gadgets.
Despite the fact that every HR92UK can measure the temperature in any explicit room, you’ll if truth be told use appropriate wi-fi room thermostats to take the temperature as an alternative. This can be required in case your radiator sits in the back of furnishings, since this will throw off the HR92UK’s temperature sensor.
In case you have underfloor heating, there are a few choices. For a unmarried manifold, one BDR91 relay and wi-fi thermostat will do the activity (you’ll see the relay tucked away within the image under, controlling my underfloor heating manifold). For a couple of zones, there are devoted underfloor controls.
Total, there’s little that Evohome can’t keep an eye on, however speccing up your device calls for some concept and time. It’s value paying for set up, too, simply to ensure that the whole lot is fitted appropriately
Honeywell Evohome – Options
Keep watch over of the device is basically during the capacitive touchscreen controller. From right here you’ll configure rooms, including within the sensors and valves that all incorporates.
As soon as your rooms are configured, you must arrange schedules. Every room may have a special time table: you’ll have your bed room, rest room and kitchen heat up very first thing within the morning, as an example, with the lounge approaching later within the day.
There’s a wizard readily available that asks you easy inquiries to construct a time table for you, however I discovered it more straightforward to set the time table manually. As soon as one room is configured, you’ll replica its time table for various days and different rooms. There’s no finding out choice to be had.
There are a few further heating modes that you’ll use, too. Optimal Get started learns how your own home heats up, so the boiler may also be became on early, making sure your rooms are heat when you wish to have them to be. Optimal Prevent will close your heating down early, letting the temperature fall by way of zero.5ºC prior to turning it again on to save lots of extra money.
Every radiator valve could also be in a position to Window Detection (configurable during the clunky on-device menu that you simply’ll wish to use the guide to decipher), turning heating off to a radiator whilst you open a window or door. The choice – known as Win Kind within the menus – is became on by way of default, however you’ll configure how lengthy it takes to cause, or even the temperature fall charge to show it on. To be truthful, you’re leaving the defaults on my own.
Fast Movements are configurable choices to set how your heating works. Heating Off units each and every room to 5ºC and comes in handy in the event you’re occurring vacation or wish to flip the heating off when wintry weather is over.
Economic system mode drops the room temperature by way of 3ºC. Day Off mode will apply the Saturday time table – it’s at hand in the event you’re running from house and need the home heat when you’re in.
Customized mode means that you can keep an eye on what occurs. For instance, I had it as a Visitor mode, which became the heating on within the spare bed room and toilet for when visitors got here spherical.
Away mode units the temperature to the extent you put, so you’ll get monetary savings whilst you pass out. Then again, with out Geolocation inbuilt, there’s no technique to set this routinely. There are two different choices, although.
In case you have Evohome Safety, you’ll set Away mode to be became on whilst you arm the alarm. Then again, that is nearly needless, as you’ll’t flip off the Fast Motion whilst you unencumber the alarm. However, you’ll use IFTTT to fireplace the rule of thumb routinely. All Fast Movements may also be set completely or on a timer.
App keep an eye on is equipped by way of the Honeywell General Attach Convenience app. From the homepage you’ll view every room, and each its present set temperature and current temperature. Faucet a room to soon alter the temperature, atmosphere it completely or on a timer.
Schedules may also be edited according to room, however you’ll’t replica them between rooms (solely between days for that room), making preliminary configuration more straightforward during the controller.
Fast Movements line the highest of the web page, even supposing they just have icons, so you might have to keep in mind what they imply – or faucet them to determine. There’s little else to do from the app, and it’s all about easy heating controls.
Honeywell Evohome – Amazon Alexa, Google Assistant and IFTTT
IFTTT strengthen means that you can set or disable a Fast Motion, because of this you’ll construct your personal geolocation regulations the usage of a carrier comparable to Existence360. However, you need to use a Flic button or Logitech Pop! with IFTTT to have a bodily button to show your heating off whilst you pass out, and again on whilst you go back house.
Amazon Alexa strengthen is inbuilt, and the reliability has progressed since release. With the talent, you’ll in finding out the temperature of a room or alternate the room temperature. Adjustments are made till the following scheduled alternate. Amazon Alexa helps Fast Movements, too, so you employ an Alexa Regimen to modify your heating mode, as an example.
Google Assistant strengthen is to be had, too. Fast Movements aren’t detected by way of the device, so you’ll’t use them in the similar approach in Google House routines. In a different way, the controls are the similar as for Alexa: you’ll get a room’s temperature or set it to the temperature that you wish to have.
Honeywell Evohome – Efficiency
The wonderful thing about Evohome is how simple it’s to make use of. Stroll right into a room and in finding it slightly cold, as an example, and you’ll simply use the dial at the thermostat to get a heating spice up. When you’re heating just one room, the radiator warms up super-quickly, because the boiler isn’t heating all the device. Adjustments comprised of the TRV are fast, and the brand new temperature is about till the following scheduled alternate.
Adjustments comprised of the app, a voice assistant or the controller take a couple of mins, because the battery-saving low energy sign is distributed much less steadily to the sensible radiator valves. This sort of extend isn’t in point of fact a topic in on a regular basis use.
I’ve had Evohome since release and feature discovered it extraordinarily dependable. Batteries within the TRVs (2 x AA) generally tend to closing round 18 months or so. The battery meter at the show signifies when it’s time to modify them out, even supposing it isn’t at all times that correct. On some events, I’ve discovered TRV has sufficient energy for the LCD, however now not sufficient to modify the valve; a chilly radiator is a great indicator that one thing must be modified.
Why purchase the Honeywell Evohome?
My checklist of the perfect sensible thermostats displays what number of merchandise there are to choose between, however Honeywell Evohome manages to differentiate itself. Sure, it’s pricey, however the vary of keep an eye on choices and touchscreen controller be offering up a flexibility that isn’t observed somewhere else.
An app replace including geolocation, or higher integration with the protection device, can be liked; however those are minor proceedings which can be simple to reside with or workaround.
When you don’t wish to splash out on such a dear device, the Nest Finding out Thermostat third Gen is the most productive single-zone-only style. If you wish to have one thing that you’ll make bigger one day, the Tado Sensible Thermostat is a smart selection with its non-compulsory sensible radiator valves.
