We Compare Smart Internet Heating Controls

How much do smart internet heating controls cost? Which is the best internet controlled smart heating system for my home? Are smart heating controls compatible with my heating and hot water system?

Welcome, to the ULTIMATE comparison of smart heating controls that are connected to the internet and accessed via a compatible smart phone!

We consider internet heating control prices for the base unit, smart radiator valves, thermostats and add on functions, as well as compare performance and compatibility, to give a true price comparison of smart internet heating controls. We have placed products into three groups to better explain the types of product on the market.

Group 1) Individually Zoned Heating and Hot Water Controls – these are sophisticated systems capable of setting different temperatures in different ‘zones’. The zones are created either via two or more separately piped radiator circuits or room by room via smart radiator controls. These systems are capable of operating heating only (for combi boilers) or heating and hot water where a tank is present.

Group 2) Heating and Home Automation Controls – these are reasonably sophisticated heating control systems that form part of a much bigger home auotmation systems for cameras and electrics.

Group 3) Whole House Controls – these are more like traditional thermostats that call for the boiler to come on in order to meet a pre-set room temperature. Most are capable of operating more than one radiator circuit, providing they are separately piped, and many have geo-location features that sense when you are nearly home to turn the boiler on (via a GPS phone signal). A couple also now work with smart radiator valves. All of these controls will operate a combi boiler and some have a facility to control and 'boost' hot water tanks.

Group 1 - Individually Zoned Heating and Hot Water Controls

The two tables below set out A) Prices and B) System Functions for internet heating controls that are capable of controlling multiple and/or individually zoned heating along with hot water functions. We have reviewed: Honeywell Evohome, Heat Genius, Drayton Wiser and Tado Smart Thermostat.

So what are the main differences?

The Honeywell Evohome and Heat Genius products are by far the most sophisticated home heating and hot water controls on the market. Both offer options to either control separate (zoned) radiator/underfloor heating circuits or individual rooms (or groups of rooms) via smart radiator valves. Both provide hot water timer AND temperature controls. Both are quite expensive and both are 'stand-alone' heating control sytems, currently with no option to control other home systems.

The Drayton Wiser range and Tado offer much cheaper alternatives to the Honeywell and Genius, but with many of the important functions. However neither offer an option to control the hot water temperature, but the Tado does allow for geo-location activation. Again these are stand-alone heating products.

Product   Heating features Can also control hot water? Options with basic unit Other zoning options Overall review

Honeywell - Evohome

Controls multiple zones

Yes - both timer and temperature

The Evohome can control a one zone system without alteration and multiple zones with pipework alteration

It is possible to create more zones without altering the pipework by fitting Honeywell's individual temperature sensors on radiators.

The Evohome is expensive if you are only going to use it as a one-zone programmer with standard TRVs. Unless you plan to zone the system or use the individual temperature sensors, one of the standalone products below might be better value. Will work with Alexa.

Heat Genius - Genius

Controls multiple zones

Yes - both timer and temperature

The Genius starter kit and Stater Kit + Hot Water will only control a one heating zone

It is possible to create more zones without altering the pipework by fitting Heat Genius' individual temperature sensors on radiators. Option for motion sensors to 'learn' occupancy and temperature levels.

The Genius is expensive if you are only going to use it as a one-zone programmer with standard TRVs. Unless you plan to use the individual temperature sensors, one of the standalone products below might be better value

Drayton - Wiser Multi-zone

Controls multiple zones

Yes - timer only

The basic control packs will do one or two (Kit 3) plumbed zones with hot water timer.

It is possible to create more zones without altering the pipework by fitting Drayton's individual temperature sensors on radiators.

A well priced one or two zone controller with options to create zones at a much lower cost to the Genius and Evohome systems. Not as sophisticated but easy to use.

Tado - Home Control

Can control 2 zones

Yes - timer only

The unit can control upto two heating zones but only with pipework adjustment

It is possible to create more zones without altering the pipework by fitting Tado's individual temperature sensors on radiators.

Will adjust temperature according to how far away you are from home (GPS). Can be voice activated via Siri, Alexa

 
Group 2 - Heating and Home Automation Controls

The two tables below set out A) Prices and B) System Functions for internet heating controls that are capable of controlling multiple and/or individually zoned heating as part of a home automation system.. We have reviewed: Devolo Home Control and HeatMiser Neo.

So what are the main differences?

The Devolo and Heatmiser systems form part of whole house control systems and for many these are the future of home heating controls. Both offer reduction functionality compared with the Evohome and Genius products. The Devolo offers no hot water controls and the Heatmiser no option to zone via smart radiator controls. However, these systems offer the homeowner other add-on functions, including cameras and electric controls.

Group 3 - Whole House Controls

The tables below again set out A) Prices and B) System Function for whole house heating controls. This group contains some very well-known internet heating controls – Nest and Hive – as well as some less well known products. 

So what are the main differences?

Of the five products featured here, the Nest has the most function, including the ability to control two separate radiator circuits (zones) and bring the hot water on. Nest have also introduced geo-location and motion sensors to know when you are home, or close to home, to turn the heating on, and the ability to work with third party smart radiator valves (although it does mean using a second app).

Of the remaining four, only Hive can control the hot water and only Netatmo has brought out compatible smart radiator controls. 

For those with a combination boiler that would like smart radiator valves, the Netatmo and Nest will make for a very decent control system. For those with a hot water tank, it will be have to be Nest. The remaining three are well priced heating only smart phoned controlled thermostats for combi boiler systems, but no more than that.
