⭐️⭐️⭐️⭐️ /5

The Nest thermostat is a smart thermostat that has taken the market by storm since its initial release in 2011. It's a sleek and stylish device that is packed with features that are designed to help you save energy and money on your heating and cooling bills. In this review, we'll take a closer look at the Nest thermostat and discuss its various features, benefits, and drawbacks.


The Nest thermostat has a modern, minimalist design that looks great in any home. It has a round shape with a stainless steel ring around the outside, and a glass screen in the center. The screen displays the current temperature, as well as the temperature you've set it to, and it also shows icons for the different features and settings.


The Nest thermostat is packed with features that make it stand out from other smart thermostats on the market. One of its most notable features is the ability to learn your schedule and adjust the temperature accordingly. This means that the Nest will automatically adjust the temperature when you're away from home or asleep, which can help you save energy and money on your bills.

Another great feature of the Nest thermostat is its ability to be controlled remotely. This means that you can adjust the temperature from anywhere, using your smartphone, tablet, or computer. You can also set up alerts and notifications, so you know when the temperature reaches a certain level or if there's a problem with your heating system.

The Nest thermostat also has a number of other features, such as the ability to set up multiple user accounts, compatibility with a wide range of heating systems, and a variety of energy-saving settings and modes.

Hot Water Control

The Nest Thermostat 3rd gen allows you to control your hot water system using the same intuitive interface as the heating control. This means you can easily set schedules, adjust temperatures and turn the hot water on or off using the Nest app from your phone, tablet or computer. You can also control your hot water system using your voice if you have a compatible smart speaker, such as Google Home or Amazon Echo.

One of the key benefits of the hot water control feature is the ability to set schedules for your hot water, so you only heat water when you need it. For example, you can set the hot water to come on in the morning when you get up and turn off automatically when you leave for work. This means you can save energy and money by only heating the water you need, rather than keeping a full tank of hot water all day.

The Nest Thermostat 3rd gen also has a "hot water boost" feature that allows you to quickly heat up your hot water if you need it outside of your regular schedule. This can be useful if you have unexpected guests or need to run a bath outside of your usual routine.

Another useful feature of the Nest Thermostat 3rd gen hot water control is the ability to monitor your hot water usage and see how much energy you are using to heat your water. This can help you identify opportunities to save money and reduce your energy consumption by adjusting your hot water schedule or reducing the temperature of your water.

Overall, the hot water control feature of the Nest Thermostat 3rd gen is a useful and intuitive way to manage your hot water system and save energy and money. Whether you want to set schedules, adjust temperatures, or monitor your usage, the Nest Thermostat 3rd gen makes it easy to control your hot water from anywhere using your phone, tablet or computer.

According to Nest, their thermostats can save users up to 15% on heating bills. This is achieved by using features such as Auto-Schedule, which learns your preferred temperature settings and creates a personalised schedule for your home. The thermostat also has a Home/Away Assist feature, which detects when you are away from home and adjusts the temperature to save energy.

Another way the Nest Thermostat can save you money is through its Energy History feature. This allows you to see how much energy you are using each day and provides tips on how to reduce your consumption.

The Nest Thermostat also has the ability to work with other smart devices in your home, such as smart lighting and smart plugs. This can help you to create a more energy-efficient home and further reduce your energy bills.

In terms of the actual savings you can expect, this will vary depending on factors such as the size of your home, the efficiency of your heating system and your current energy usage habits. However, many users have reported significant savings after installing a Nest Thermostat and using its smart features to optimise their heating.

Overall, while the upfront cost of a Nest Thermostat may be higher than some traditional thermostats, the potential long-term savings on your energy bills make it a worthwhile investment for many homeowners in the UK.
