Smart Heating Controls

Smart heating controls

If you get a new heating system installed today, the chances are it will be installed with a thermostat and a programmer (find more information about these by clicking on the links at the top of the page). In many cases TRVs are also installed on radiators to give people a further level of heating control.

The heating pattern set by the programmer and thermostat (to limit the upper temperature the house gets heated to), should match your heating requirements – and the closer you can match them, the more you will save.

What’s the issue with standard heating controls?

The issue is though, that during the day you might want different temperatures in the home, or for the heating to come on based on a slightly different pattern than the programmer is programmed to do. The ability to further refine the level of heating controls on the home results in even larger savings – and there are big companies like Google investing £millions to help drive home automation and smart heating controls.

There are lots of different companies currently producing smart heating controls – for example Honeywell with their EvoHome offering, Google with their Nest smart thermostat and even the newer Tado thermostat.

While many companies are entering the smart heating control market, there are a lot of similar features within the units they develop. Here we take a look at some of those features to see if you could fine tune your heating system.

Ability to control your heating using an App

This is now central to most of the smart heating controls out there, while you might not be able to alter individual room temperatures, pretty much all of them have an App (normally smart phone or tablet based) that allows you to turn the heating on or off from wherever you are in the world. Add in to the mix a remote controlled thermostat and you can set average temperature your home will reach – all from the touch of a button.

This is a great feature especially if like us you forget to turn off the heating / hot water when you go on holiday. Obviously you don’t want the heating completely off in the middle of winter so pipes freeze but if you aren’t in the house, heating it to 20 degrees is a waste of money.

A heating control system that learns

While this sounds like something out of the terminator, actually it is pretty boring, but rather clever! The smart controls use a combination of sensors, hardware and algorithms to make heating decisions. As you’d expect they have temperature sensors, but they also often have light or movement sensors, humidity sensors and even up to date weather information from an external source via a wifi connection. This allows the heating system to learn your behaviour and the temperature of the house you like and then set the heating accordingly.

Some of the older smart thermostats like Nest, (that is just a single thermostat – albeit a smart one), will only make these calculations based on one location in the house, but some of the more advanced smart heating controls like the Heat Genius system for example have sensors in lots of different locations – this allows the system to develop a much more accurate heating pattern.

Remote controlled electronic TRVs

TRV’s are the thermostatic valves found on radiators – these all allow you to control temperature of individual rooms and are normally manually set with a bezel that allows you to set the heating typically at a level between 1 and 5. They work when a wax or liquid filled capsule expand or contract when the room gets hot or cold causing it to close or open the radiator to new hot water.

Electronic TRV’s are a newer invention, and are key to the more sophisticated smart heating controls. Instead of the expansion or contraction of a material, they are mechanical and read the temperature of the air using an electronic thermometer.

The best electric TRVs are then controlled remotely from a central thermostat – this allows you suddenly to control the temperature of individual rooms, again allowing you to warm up a spare room if you have someone over to stay or likewise turn down the heating if the kids are at school during term time.

The EvoHome system and the Heat Genius systems both have remote controlled TRV’s that can be controlled centrally by an app on a phone or the control panel (in the case of EvoHome).

Geo Fencing

Geo fencing is a relatively new technology and takes advantage of your phone signal. Your phone tracks exactly where you are in the country and then as you approach home it will turn the heating on for you – likewise when you leave home in the morning it will turn the heating down, all without you having to do anything. This is a bit of an extension to the smart thermostat learning ability, but again it is directly coordinating your heating based on your behaviour.

The one downside of this (or at least a downside experienced when we tested a model) was the rate at which the phone battery died when you have location services turned on, but obviously with more and more people using their phones to help them navigate around cities perhaps this is less of an issue.

Energy Usage

Aside from just the ability to turn your phone into a mobile control panel for your heating, some of the apps that come with the smart heating systems also can show your actual usage, projected usage, cost etc etc. The Tado is particularly good here and as time goes on this feature will no doubt be used in all the apps that are built.

The Future of Smart heating controls

As time goes on, undoubtably the smart heating control manufacturers will come up with new and improved ways to make smart heating controls even better. We will continue to update this page as we hear about these great new features so be sure to come back and check it out!
