Smart Thermostat Buying Guide

Features to Look for in a Thermostat

As with any product, knowing exactly what components make a great thermostat will narrow your search:

Compatibility

This is one of the most important factors to check before you purchase any item. Ask yourself: Is the item compatible with your home set-up? There is nothing worse than purchasing a thermostat just to find that it won’t work with your heating system. Check what manufacturers a thermostat is compatible with by asking a technician at a local retailer.

Programmability

This is something that could save you money in the long run. Is being able to control separate rooms important to you? If so, check to see how you the programming works. Let’s say you want the bathroom to be warm in the morning, and no heat in the bedroom at night. A smart thermostat can manage these requests for each room. With a smart thermostat that’s programmable, you’ll save energy.

Display

Deciding what kind of display you need is small but important. Some users prefer a large display to read. Others might seek out a display that is back lit to make it easy to see in the dark. A great thermostat will have several display options.

Remote Access

If you want to change your heat settings or check your home heating while on the go, remote access can be handy. The ability to edit your settings from afar means that you can be prepared for a cosy home anytime. When checking a specific thermostat, see if there is an app or set-up requirements for your smart thermostat. That way, you can gain access to it even if you aren’t in the house.

Monitoring Usage

One of the main purposes of smart thermostats is to allow you to monitor your energy usage. You can potentially save money if you see where you may be wasting energy. You can have a look at the habits to adapt and to change so that you use the least amount of energy and keep your house cosy.

Unique/Extra Features

Some products have additional features such as weather reports or traffic updates. Other features allow you to customise your display or find information on cheap energy prices. These may not be necessary to everyone, but they can be handy if you’re on the move a lot. If you know the weather, you can turn your heating and air conditioning on or off to accommodate the weather.

Once you know what you want, it’s time to start looking.
