One To Avoid

Beok Wifi Thermostat for Gas Boiler Smart Wireless Room Thermostat

We tested the Beok WiFi Thermostat for Gas Boiler and, from the very start, it was one of the most frustrating smart home devices we’ve ever set up.

Installation isn’t straightforward (you’ll likely need a qualified electrician), and once connected, getting it to pair with WiFi and the Tuya app proved unreliable. The Bluetooth connection was just as inconsistent, often refusing to pair at all.

While the LCD display is clear and the thermostat technically offers features like manual and programmable modes, temperature calibration, and smart home compatibility, these positives are overshadowed by its flaws.

In use, temperature readings were inaccurate by several degrees, heating regularly overshot the set point, and at times, the system would turn on or stay on without reason. Even when the correct temperature was reached, the thermostat was slow to respond, wasting energy in the process.

The app control was equally disappointing, ignoring commands or failing to adjust temperatures as intended. Add to this the loud relay click, unresponsive touch buttons, and some of the worst instructions we’ve seen, and it’s clear this thermostat simply doesn’t deliver.

Despite its smart promises, it’s unpredictable, unreliable, and ultimately a poor choice for anyone needing dependable heating control.

How We Evaluated and Chose the Best Smart Thermostats for UK Homes

When choosing the best smart thermostats for UK homes, we went far beyond simply adjusting temperatures and checking an app. We examined every factor that matters to homeowners, from installation to daily performance, to find the models that truly deliver.

Compatibility and Installation

The first step was ensuring each thermostat worked with a wide range of UK heating systems, including gas and combi boilers, heat pumps, and underfloor heating. We assessed whether extra wiring, such as a C‑wire, was needed and noted how straightforward it was to install.

We also looked at whether fitting could be done with basic DIY skills or if professional help was required. App pairing was another key consideration, checking how quickly and reliably each model connected to Wi‑Fi and integrated with popular smart home platforms.

Performance and Temperature Accuracy

We tested how accurately each thermostat measured room temperature and how quickly it brought the home to the desired warmth. We monitored whether the temperature stayed consistent without frequent fluctuations and how effectively additional sensors balanced heating in different rooms.

Smart Features and Automation

Modern smart thermostats promise intelligent automation, so we examined how well they adapted to household routines, responded to geofencing triggers, and adjusted based on local weather conditions.

We also tested integration with Alexa, Google Assistant, and Apple HomeKit to ensure voice control was reliable and useful.

Energy Efficiency

Energy savings are one of the biggest reasons to invest in a smart thermostat. We compared energy consumption before and after installation, checking whether eco‑modes and adaptive settings could lower heating costs without affecting comfort.

Usage reports were also reviewed for clarity and practical insights.

Design, Build, and Usability

A good smart thermostat should be both functional and well‑designed. We looked at display clarity in different lighting, how intuitive the controls felt, and whether the materials used were durable and attractive. We also considered how well each model suited both modern and traditional interiors.

Reliability and Support

Finally, we monitored Wi‑Fi stability, update frequency, and responsiveness to software improvements. We contacted each manufacturer’s support team with technical queries, noting the speed and quality of their responses.

Frequently Asked Questions

What Exactly Does A Smart Thermostat Do?

A smart thermostat automatically controls your home’s heating and cooling systems, learning your preferences and adjusting temperatures for comfort and efficiency.

It can be managed remotely through an app, schedule heating based on your lifestyle, and often uses sensors or location tracking to optimise energy use.

Can A Smart Thermostat Work Without Wi-Fi?

A smart thermostat can still operate basic heating and cooling functions without Wi‑Fi, but you’ll lose remote control and many advanced features.

Without internet access, it functions more like a traditional programmable thermostat, requiring manual adjustments directly on the device rather than through a connected app.

What Is The Difference Between A Smart Thermostat And A Wi-Fi Thermostat?

A Wi‑Fi thermostat allows remote control of your heating and cooling via an internet connection, but doesn’t necessarily learn your habits.

A smart thermostat goes further, using automation, learning capabilities, and energy‑saving algorithms to adapt to your lifestyle, making adjustments without constant manual input from you.

Do Smart Thermostats Need Wiring?

Most smart thermostats require wiring to connect to your heating or cooling system, though the exact setup depends on your existing system. Some models may need additional wires, such as a C‑wire, for consistent power.

Battery‑powered options exist but often have fewer advanced features compared to wired versions.

Are Smart Thermostats Actually Worth It?

Smart thermostats can be worth it for many households, as they often reduce energy bills, provide greater comfort, and offer convenient control.

The ability to optimise heating and cooling based on schedules, occupancy, and weather can lead to long‑term savings and improved efficiency, making it a valuable upgrade.

Can I Install A Smart Thermostat Myself?

You can install a smart thermostat yourself if you’re confident working with electrical wiring and understand your heating system. Many come with clear instructions for DIY installation.

However, some setups may require a professional, especially if additional wiring is needed or your system is more complex than average.

Can A Thermostat Affect My AC?

Yes, a thermostat directly controls how and when your air conditioning operates. An efficient, properly set thermostat can improve cooling performance and reduce energy waste.

Conversely, incorrect settings or faulty sensors may cause your AC to run inefficiently, leading to uneven temperatures, higher costs, and unnecessary wear.
