Can Smart Thermostats Be Used With Any Boiler? Checklist

Can Smart Thermostats Be Used With Any Boiler

Over the past few years, more and more homes worldwide are making use of smart technology such as smart thermostats.

However, before you take the plunge and switch to a smart thermostat, consider whether your heating system is compatible with it.

For instance, can a smart thermostat be used with any boiler? 

Smart thermostats can be used with most any modern boiler. However, some older or damaged boilers will not connect to a smart thermostat. Before buying a smart thermostat, be sure to check its compatibility to ensure it will work with your heating system. 

This article explores everything you need to know about connecting a smart thermostat to a boiler.

It also considers the advantages of using smart thermostats and the best ones currently on the market. 

How To Check if a Smart Thermostat Is Compatible With a Boiler

Smart thermostats connect with boilers and other heating systems and with your smart device.

Users can then set the heating system temperature using the smart thermostat app on their phones. 

There are several ways to check if your boiler can be connected to a smart thermostat

If your boiler is already connected to a regular thermostat, it is likely compatible with a smart thermostat. Most smart thermostats need to be connected to existing thermostats to function. 

You can also consider how old your boiler is. Boilers that are a few decades old may not be compatible with smart technology like smart thermostats. 

If your boiler is significantly run down, it may not be a good idea to connect it with a smart thermostat.

The boiler’s hardware may be more likely to deteriorate, which will affect its connection with the smart thermostat. It may be wiser to repair your boiler before connecting it. 

The type of boiler you have is also relevant.

Most oil and gas boilers will connect to a smart thermostat unless they are over a decade old. However, smart thermostats can’t be used with plug-in electric boilers. 

The best way to determine if your smart thermostat can be used with your boiler is to consult with a handyperson or electrician.

They have a deep understanding of different thermostats and boilers in the market and judge if they are compatible. 

How To Connect a Smart Thermostat to Your Boiler

Electricians Can Connect Your Smart Thermostat To The Boiler Safely

Once you’ve confirmed that your smart thermostat can be used with your boiler, you may be tempted to connect it yourself. 

Resist that temptation and call in your electrician!

Electricians will be able to connect your smart thermostat to your boiler safely.

They also tend to have insurance packages that will cover any damage that happens during the installation. 

Some companies that sell smart thermostats partner with electricians to install their thermostats in customers’ homes. 

The smart thermostat may need a battery or a power source to work. It will also need to be connected to a WiFi network.

Why Should You Connect a Smart Thermostat to Your Boiler?

While you now know that it is possible to connect your smart thermostat with a boiler, you may be wondering why you should consider a smart thermostat in the first place. 

Smart thermostats are popular for a variety of reasons: 

  • Ease of use. A study conducted in 2020 found that users of smart thermostats appreciate how easy they are to use. They can be controlled with a few taps on users’ devices, allowing users to make the temperature in their homes more comfortable without needing to get up! 
  • You have reduced energy consumption. Because it is easier to use smart thermostats, your energy consumption may decrease as you will be able to turn on and off your heating system remotely. That way, if you forget to turn off the heating before a weekend away, you can easily switch it off from your smart device. 
  • Cost savings. Reduced energy consumption.
  • Geolocation features. Some smart thermostats record your device’s geolocation and will send you alerts to turn on or off the heating if you are leaving or coming home.
  • Weather detection. Similarly, many smart thermostat apps will recognize the weather and send users a suggestion to adjust temperatures based on the weather. 

However, be mindful of the number of times that you change the temperature in your home.

A study found that users of smart thermostats are more likely to change the set temperature on their heating systems frequently. 

Be sure not to fall into that trap as you’ll increase your energy consumption!
