10 Best Electric Wall Heaters 2025 in the UK

The Devola Wifi Enabled Smart Electric Glass Panel Heater is a 2000W heater that offers smart features for convenient home heating. It supports WiFi connectivity and can be controlled via the Tuya Smart App or voice commands through Alexa and Google Home, making it highly versatile for tech-savvy users. The heater includes a precision thermostat that maintains room temperature efficiently, which can help reduce energy costs.

It also has a 24-hour timer and auto shutoff feature for added convenience and safety. The IP24 rating ensures it is safe for bathroom use, though it should be installed by a qualified electrician in such settings. The sleek design with dimensions of 78 x 47 x 7.5 cm and a weight of 8.5 kg makes it suitable for wall mounting, but it can also be used as a freestanding unit, adding to its flexibility.

However, it initially requires connection to a 2.4GHz WiFi network, which may be a bit cumbersome for some users. The noise level is not specifically mentioned, but electric panel heaters are generally quiet. With a 1-year warranty that can be extended to two years, the Devola heater offers good reliability. Some users might find the need to disable 5GHz WiFi for initial setup inconvenient, and the white color may not suit all decors. This heater is ideal for medium-sized rooms up to 25 square meters and is particularly beneficial for those looking for a modern, energy-efficient heating solution with smart features.

The Purus 600W Electric Radiator Heater is a compact and lightweight option well-suited for small rooms up to about 7.5 square meters, such as bedrooms or bathrooms. Its 600-watt power level is on the lower side, so it’s best for modest heating needs rather than large spaces. It features an advanced thermostat with precise temperature control (accurate to half a degree) and a convenient digital LED display, making it easy to set temperatures between 5°C and 35°C. One standout feature is the eco-friendly auto open window detection, which saves energy by turning off the heater if it senses a sudden temperature drop, helping to avoid wasting power when a window is open.

Safety-wise, the heater is IP24 rated, meaning it is splash-proof and suitable for bathroom use, provided it’s installed by a qualified electrician. It also includes an auto shutoff feature for added peace of mind. Installation is flexible: you can wall-mount it or use the supplied feet to make it floor-standing. The power cable is a standard length (1.75m), and the unit plugs into a standard UK socket, simplifying setup.

In terms of noise, Purus does not highlight any specific noise level, but panel heaters like this typically operate quietly, making it appropriate for bedrooms or quiet spaces. The slim grey panel design (about 45cm wide and 8.5cm deep) is unobtrusive and modern-looking, fitting well into various room decors without taking up much space. A few drawbacks include its limited heating capacity, so it’s not ideal for poorly insulated or larger rooms. Also, while it is lightweight and easy to install, professional installation is recommended for bathroom safety compliance. Customer reviews indicate good reliability and responsive customer support from Purus. This heater is a practical, energy-efficient choice for small indoor spaces needing gentle, consistent warmth, especially in bathrooms or bedrooms where quiet operation and safety are important.

The Moda Onyx Smart Electric Heater is a 2000W wall-mounted unit designed for indoor use, suitable for spaces up to 20m² such as conservatories, spare rooms, home offices, or workshops. One of its main strengths is its user-friendly control options, including a touchscreen interface and WiFi app control through Smart Life or Tuya, as well as compatibility with Amazon Alexa and Google Home for voice commands. This makes it highly convenient for those who enjoy modern smart home technology.

The heater also offers multiple modes like Comfort, Eco, and Anti-Frost, which provide flexibility depending on your heating needs. Additionally, it is easy to install, either mounted on a wall or used freestanding, with all necessary fixtures included, and comes with a 2-year warranty for peace of mind.

On the downside, some users might find its noise level higher than expected, and its size (D7 x W80 x H45cm) and weight (8 kg) might be cumbersome for smaller spaces or frequent relocation. Also, the IP22 rating means it is protected against limited dust ingress and water spray less than 15 degrees from vertical, which might not be sufficient for more demanding environments. Despite these concerns, it stands out for its blend of aesthetics and smart functionality, making it a good choice for tech-savvy individuals looking for an efficient and stylish heating solution.
