Buyer’s Guide To Thermostats

The main point of a thermostat is to regulate heat according to your settings – everything besides that is generally seen as a bonus feature or a supplemental extra. That’s not to say that you should focus on this heat performance and nothing else, though: there are hundreds, if not thousands, of different combinations of features available, all with their own purposes and ideal uses. If you have a specific set of requirements or preferences that you want to fulfill, then it’s not hard to start searching for the perfect thermostat.

Like all purchases, it’s important to narrow down your search and figure out what’s important to you before you start looking. This makes it really easy to filter out products that just won’t cut it, especially if you have a very specific niche problem or issue that needs to be fixed.

Smart Thermostats

A Smart Home is any home that relies on a lot of ‘smart’ appliances, ranging from digital assistants to Wi-Fi enabled washing machines or refrigerators. Not everybody likes the idea of smart devices, especially in terms of privacy, but they can be quite useful for people with hectic or busy schedules that don’t have time to adjust everything manually.

A smart thermostat takes this idea and applies it to an entire heating system, letting it adjust the temperature based on a number of different inputs and factors – especially when it’s combined with a digital assistant or mobile app. This can give you plenty more levels of control and customization: for example, you can tell your digital assistant to change the heating settings through voice commands, or link it to a series of sensors to have the heating adjust based on the current temperature of occupied rooms.

Beyond that, a Wi-Fi enabled thermostat can be useful even if you’re not activating any of its smart features. You might be able to adjust the temperature settings from a mobile app, meaning that you can turn the heating off remotely or set it to warm up by the time you get home. In some cases, you might even be able to use the smart system to split heating between different rooms, especially if your space heating system was already designed with that in mind.

Compatibility

Not all heating systems are identical, and there are very few thermostats that can handle every single possible system design equally. There’s an obvious distinction between electricity-based, oil-based, and gas-based heating, but a surprising amount of thermostats can actually work with all three: the main problem area is the connections.

If a thermostat can’t physically connect to your heating system, even with some kind of adapter, then there’s no way it can influence its settings or change how it works. If you aren’t careful, you might even end up buying a thermostat that can’t be connected to your heating system at all. If this happens, you either need to get a new thermostat model or completely re-work your heating from the ground up, neither of which is ideal.

This can also be an issue with smart thermostats since not all of them work with all digital assistants or mobile devices. This is especially true for ones built by companies that already make smart digital assistants since they might restrict it to their own technology if they’re able to.

Performance

A thermostat should help you save money, but that’s not its only purpose. They’re also designed to keep you comfortable, get rid of unwanted temperature changes, and generally act like a better control method for large, complex heating systems that don’t have a single accessible control.

Two of the best features for this kind of control are scheduling systems and automatic energy-saving modes. These can be used to reduce (or even completely stop) the heating system’s power usage when nobody is home, which can be useful for people whose schedules keep them out of the house for quite a long time over certain days. If you’re able to schedule it, you can even set up a custom day-by-day system that automatically turns the heating off at times you’ll be at work or running errands, but turn it back on just before you’d normally get home.

That’s not the only kind of performance that matters. As you might expect, some thermostats are better at increasing or lowering heat levels than others, although a large part of that depends on the heating system itself. A good heating system and good thermostat can result in faster temperature corrections and adjustments than bad ones, so it’s always worth looking into their general performance and reliability if you’re going to use them often.

Simplicity vs. Complexity

One of the biggest hurdles you’ll need to jump is deciding how complex you need your thermostat to be. Having a massive range of options can be useful, but it can also feel like too much for a smaller household that won’t use even half of them. This can be even harder with smart thermostats since they often have special features that only work when combined with other smart devices. The more complicated a device is, the harder it can be to use it at all.

On the other hand, an ultra-simple thermostat might lack some key features that you want (like a scheduling system or temperature readouts in more than one measurement unit), and it can be harder to use something like a programmable heating schedule if you’ve only got a handful of buttons to work with. It’s vital to figure out what kind of features you actually need ahead of time since this can save you plenty of hassle in the long run.

Expert Tip

Some thermostats can work with ventilation systems to help you massively reduce the heat in your home, which is important in hot weather. However, others might only work with heating systems, especially if they have a simpler overall design.

Did you know?

Almost all thermostats will save you money on heating in the long run, even if they have a very limited set of options and features. Advanced features can help you save more, but only if you’re actively using them, so don’t be afraid to ignore a high-tech thermostat if you wouldn’t use its extra settings anyway.
