10 Best Wifi Heaters 2026 in the United States

The Rinnai RXP199iN is a powerful tankless water heater designed for whole-house use, delivering up to 11.1 gallons of hot water per minute with a heating capacity of 199,000 BTU. It supports both natural gas and propane and can be installed indoors or outdoors, making it flexible for various home setups. Its energy efficiency is a strong point, featuring a high UEF rating of 0.98, which means it uses fuel very efficiently and can help lower your utility bills compared to traditional water heaters.

The built-in recirculation pump with Smart-Circ technology enhances comfort by providing hot water quickly while minimizing water waste. For smart home enthusiasts, it offers WiFi connectivity through an optional Rinnai Control-R module, allowing remote monitoring and control via an app. The unit is compact and wall-mountable, weighing 58 pounds, with limited portability due to gas connections. Safety features like Smart Sense gas control are built in, providing reliable protection during operation.

This model is well-suited for large households needing reliable, continuous hot water with energy savings and smart home integration. It requires professional setup and investment in optional smart controls for full functionality.

The Dyson PureCool Hot + Cool combines three devices in one: a heater, air purifier, and fan, which is a big plus if you want clean air alongside heating. It heats rooms evenly and quickly up to about 800 square feet, thanks to its powerful heat projection technology. WiFi connectivity allows you to monitor air quality and control the unit from your phone, making it smart and convenient to use.

The HEPA filter captures very fine particles like dust, pollen, and smoke, helping improve air quality effectively. It also senses pollution levels and reports them in real time, keeping you informed. Dyson’s design is known for quality in terms of safety and noise.

The unit is somewhat heavy (over 12 pounds) and tall, so it’s less portable than simpler space heaters. Its sleek white design fits modern rooms well but may be bulky for small spaces. This product is ideal for those who want a high-tech heater and air purifier combo with smart features and strong filtration; however, if you need lightweight or very energy-efficient heating, you might want to compare other options.

The Dyson Hot+Cool AM09 is a sleek, bladeless tower heater designed mainly for indoor spaces like bedrooms or home offices. It uses radiant heating with forced air to warm rooms, offering a modern, safe, and quiet alternative to traditional heaters. One of its standout features is the bladeless design, which makes it safer around children and pets and easier to clean. While it's lightweight and portable enough to move between rooms, its size is more suitable for medium-sized spaces rather than large areas.

The heater offers two-speed settings, allowing some control over the heating intensity. Notably, this model does not list WiFi connectivity, which may be a drawback if you want to control it remotely via an app or smart home devices. Noise levels are generally low, making it suitable for quiet environments like bedrooms or studies. The product carries a 90-day limited warranty and has received positive user reviews for its reliable performance and safety features.

For users seeking a WiFi-enabled heater with detailed energy-saving modes or precise temperature controls, this model might not fully meet those needs. It is best suited for users prioritizing design, safety, and straightforward heating without smart connectivity.
