Eve Thermo review

The third technology of the Eve Thermo is available for purchase. So is now the time to take residence this good TRV?

So, what’s the Eve Thermo, precisely? It’s a sensible thermostatic radiator valve. It replaces the atypical management valve on a single radiator and can be utilized to remotely management the temperature. Which means it solely controls the radiator it’s hooked up to – it’s not a whole good residence heating system.

The catch with this product is that it’s Apple suitable solely. On the very least, you want an iPhone. For optimum functioning, you also needs to have an Apple product you should use as a hub for distant management if you’re not at residence.

Value & availability

The Eve Thermo is at present out there from a lot of retailers. You may get it from Amazon for £59.95 or direct from the Eve web site, the place it prices €69.95 (£59.71). There’s at present a deal on, so if you happen to use the code Thermo20, you may get it for simply £47.59. It’s additionally out there from the Apple retailer, for £64.95.

At full value, it is costlier than some comparable units. It’s nearly £20 greater than the Tado good TRV and £10 greater than the associated Hive product. Nevertheless, these are add-ons for a sensible residence heating system. The good benefit of Eve is that it may be used independently of a sensible thermostat. Certainly, you do not want a sensible thermostat in any respect, however the true benefit is that the Eve Thermo will work alongside any thermostat.

Sensible residence ecosystem

Like so many good residence merchandise now, whether or not or not the Eve is an efficient buy will depend upon what different merchandise you personal – in different phrases, it’s a query of whether or not it matches in along with your know-how ecosystem. In the event you already personal Apple or Eve units, the Eve Thermo is an efficient wager for you. For full performance, you’ll need to make use of Apple’s good residence system, HomeKit. This entails having Apple TV, a HomePod or an iPad you should use as a hub. However as a plus, which means that you should use Siri voice instructions to regulate your heating remotely.   

In the event you don’t have a hub however you do have an iPhone, you may obtain the Eve app and use a lot of the options by way of Bluetooth.

The difficulty is that management by way of Bluetooth is proscribed by distance from the Thermo. With no hub you may’t, for instance, flip up your radiator if you’ve simply left the workplace. Nor will your Bluetooth attain essentially prolong far sufficient to can help you management your heating from anyplace in your house – by way of Siri or the app. It labored efficiently throughout our trial, however that received’t essentially be the case for bigger properties, though you can too purchase an Eve Bluetooth vary extender.        

Clearly, it will get costly if you happen to have been to suit all of your radiators with Eve Thermos, however you would begin by becoming them to radiators in rooms you wish to warmth solely at sure instances. For instance, match them in rooms you do not use through the day so that they’re solely heated within the night prepared for bedtime, say.

Set up

Set up is straightforward. To make use of it, unscrew the prevailing valve in your radiator of alternative and swap it for the Eve Thermo. The product comes with three totally different connecting rings, so it should match most varieties of radiator. It was suitable with all radiators in my residence.

The Eve Thermo is only a bit bigger, smoother and extra strong that an atypical radiator valve. When you have a white radiator, it is going to be a smooth and inconspicuous accent. If not, it’s going to face out like somewhat white bobble hat.

We reviewed an earlier iteration of the Eve Thermo again in 2016. On the time, we felt that the dearth of a show and buttons to regulate the temperature on the machine itself was a little bit of a flaw. We identified that any home friends can be unable to regulate the temperature if the room they have been in featured an Eve Thermo.

The brand new-generation Eve has been up to date with these features. When it’s arrange, the temperature seems in a delicate LED show on the machine itself. The show disappears when not in use to avoid wasting on energy (the Thermo runs on two AA batteries).

There are keys that can help you alter the temperature on the TRV with out utilizing the app. Nevertheless, the Eve app additionally features a visitor entry possibility so if your customer has an iPhone, you can provide them entry to your heating system.

Efficiency & app

The important thing benefit of a sensible thermostat of this type is that you could alter the temperature in a single room. Whereas good heating methods reminiscent of Nest offers you total management of the temperature in your house, it will possibly nonetheless range uncomfortably from room to room, relying on the location and effectivity of the radiators and the room dimension. In observe, this may imply that your bed room is oven-like, whereas your sitting room is languishing in an arctic chill.

There’s one other plus to utilizing the product. Previous to utilizing the Eve Thermo, most individuals haven’t any system past trial and error for setting the temperature on the dumb valve’s numbered system of 1-5. What does three imply on a radiator valve? How a lot cooler is it than setting your valve at 4?

The numbers solely actually serve to let you already know if you happen to’re adjusting the temperature up or down. Basically, we’d simply fiddle round with the valve till the room appeared about proper, with out understanding what temperature that equated to.

Not solely does the Eve Thermo can help you set a exact temperature (in increments of 0.5°C), however you are able to do so on a schedule. 

Utilizing the app, you may instruct the Eve to show the radiator down throughout instances you’ll be out and again on to heat the room up to your return. The limitation is that you could’t swap the radiator off totally and you’ll’t override the boiler settings (you may’t make a radiator sizzling when the boiler is off).  

This not solely provides you a greater sense of what your heating is costing you however ought to can help you lower your expenses on electrical energy payments by scheduling it to activate solely if you want it. As soon as you’ve got established a schedule, you can arrange days off. 

An alternative choice, if you are utilizing iOS 11 or later and have an Apple hub, is to make use of location providers to geofence your machine, so it will come on solely if you return residence.

In a additional new characteristic, the Eve will even flip down the radiator if you happen to open a window to air out the room, conserving power.    

The free-to-download Eve app is intuitive to make use of and properly laid out. There’s a literal ‘residence’ web page that shows the entire Eve units in your house, though you can too select to view your units by room. Equipment might be grouped collectively, so you may create Scenes, as you’d with a HomeKit.

Eve app

A Scene is a concurrently occurring group of occasions affecting your good equipment. For instance, you would arrange a Scene that activates your heating an hour earlier than you get residence, or switches in your good lights 5 minutes earlier than your scheduled arrival time. Nevertheless, to make full use of this operate, you’ll need a hub.

There are a selection of different Eve equipment, together with an LED mild strip, a movement sensor, a smoke detector and a door and window contact sensor which might be managed via the identical app, so if you happen to like this product, you can begin to construct up a related good residence system. 


The Eve Thermo is a well-designed product with a well-designed app. It may be put in rapidly and simply. When you have Apple merchandise or just wish to take pleasure in a few of the advantages of good heating with out diving straight in to a full good residence heating system, the Eve Thermo is a good place to start out.
