Thermostats allow you not only to select a desired temperature at your heating device, but also to programme set-point temperatures in the home. This means your heating will turn on and off automatically depending on the ambient temperature and the time slots you have programmed. You'll only heat your home when required which can save you up to 25% on your heating (or a bit less if you are using a thermostat to control an air conditioner).
Compatible with practically all heating and cooling devices and systems (including boilers, wood burning stoves, electric radiators, underfloor heating and air conditioners), a thermostat, or programmable room thermostat, should be chosen to match your budget and your requirements.
Thermostats all come with different programming options and may be wired or wireless, the latter of which are easier to install. Smart thermostats will cost you more but means you can control your heating remotely via a laptop, smartphone or tablet.
Thermostats allow you to allocate set temperatures for each room of the house. Each thermostat comes with at least three basic pre-programmed modes.
Of course these modes can be modified if you plan to be away for a while, if you don't spend much time at home or if you have any other particular requirements.
In addition to these basic settings you can add a wide selection of settings to match your lifestyle including the time you wake up, go to work, and so on.
Wired thermostats are generally only installed if you are changing your heating system or as part of a wider renovation project since you will have to run the electrical wire through the walls. The unit itself should be secured to a wall far from any heat sources (ovens, fireplaces, etc.).
Wireless thermostats operate by connecting to your Wi-Fi network so can be moved around easily. But be sure to check that your thermostat is within reach of your router.
Smart thermostats can be controlled from your smartphone, laptop or tablet. No matter where you are – in the office or on holiday – you can change your heating or air conditioning settings to meet your needs. For example, you might want to turn the heating on an hour earlier or later than planned.
Some models even feature a geolocalisation feature which works to adjust temperatures just before or after you leave the home.
It goes without saying that a thermostat must be compatible with your heating or cooling device or system. For example, some models won't work with a high-voltage electrical heating system.
Be sure to check the hysteresis of the thermostat. This refers to the difference between the temperature at which the thermostat switches off and the temperature at which it switches on again. For example, with a thermostat with a hysteresis of 1°C and a set temperature of 19° C, the heating will go on at 18.5° C and turn off when it reaches 19.5° C. The hysteresis may be fixed or adjustable.
You should also think about the design of your thermostat as well as installation – these units can be surface- or flush-mounted.
From there, you can think about the types of features you want.

First of all, my studies have nothing to do with decoration or DIY as I was specialised in management. My passion in DIY started 5 years ago (very recently!) Everything started when we bought a house to renovate from floor to ceiling. As I’m a self-taught person, I started working on different house projects both inside and outside. My husband helped me but the student soon overtook the teacher! And as there are a lot of green spaces in Wales, gardening tools have no secrets for me. My friends and family often come to me for advice when it comes to DIY. Today, I want to share this knowledge with you!
