Who it fits
Good fit for
You should consider this heater if you are building a large infrared or traditional sauna. The 18 kW rating suits spaces up to 1,236 cubic feet. The direct-contact stone design appeals to those who prefer a milder, longer-lasting heat profile. If you want remote management via WiFi, the included UKU control fits your needs. The stainless steel build ensures durability for high-temperature environments.
Who should skip it
Skip this option if your sauna room is smaller than 636 cubic feet. The 18 kW output will be excessive for tight spaces. You might also look elsewhere if you need a 120V connection, as this unit requires a 240V, single-phase supply. The setup needs a 50-amp breaker and 8 AWG wire. If you prefer a wood control panel, note that this listing specifies the glass version.
Verdict: This heater is a robust choice for large sauna rooms that need substantial heat output. Its WiFi control and durable stainless steel build make it a practical option for serious sauna enthusiasts.
Key specs explained
Power Output: 18 kW
This wattage indicates the heater’s ability to raise the temperature of your sauna room. An 18 kW unit is designed for larger spaces, specifically rooms between 636 and 1,236 cubic feet. You should verify your room dimensions before purchasing. Smaller rooms may overheat quickly with this output, while larger spaces might struggle to reach the desired temperature efficiently. This spec ensures you match the heater to your available space.
Stone Capacity: 550 lb
The heater holds 550 pounds of rounded olivine stones. More stones retain heat longer and provide a milder, more consistent sauna experience. They absorb warmth from the elements and release it slowly, even after the heater cycles off. This capacity supports the 18 kW power output by storing sufficient thermal energy. You benefit from stable temperatures and reduced need for frequent reheating during long sessions.
Control Type: WiFi UKU Control
This feature allows you to manage the sauna heater remotely via a smartphone app. You can start heating before you arrive, adjust temperatures, and monitor status from anywhere. The glass control panel offers a modern interface while the WiFi connectivity adds convenience. This is ideal for users who want precise control over their sauna schedule without needing to physically interact with the unit.
Material: Stainless steel
The heater is constructed from stainless steel, which provides durability and resistance to corrosion. This material choice ensures the unit withstands the high-heat, high-humidity environment of a sauna room over many years. Stainless steel is also easier to clean and maintain compared to painted metals. You can expect a robust build that complements the industrial aesthetic while offering long-term reliability for your home sauna setup.
Design and build details
According to the listing, the HUUM Hive heater features a stainless steel construction. This material choice suggests durability and resistance to corrosion in high-heat environments. The unit is a floor model equipped with adjustable legs. This layout allows you to level the heater on uneven surfaces, ensuring stability during operation.
The heater has a cylindrical design with a diameter of 22 inches and a height of 29.5 inches. These dimensions indicate a compact footprint that fits into standard sauna rooms without occupying excessive floor space. The control panel is available in a glass finish. This option complements the modern aesthetic of the heater and likely offers a sleek interface for adjusting settings.
The unit includes 550 pounds of rounded olivine diabase stones. These stones have a high-heat capacity and are designed to sit directly on the heating elements. This direct contact creates more exposed stones, which the listing states produces a longer and milder heat. The air tunnel design is intended to shorten heat-up time and extend the life of the heating elements. You should ensure your sauna room meets the recommended capacity of 636 to 1,236 cubic feet for optimal performance.
Setup and daily operation
Installation requires a dedicated 240-volt, single-phase circuit. The heater draws 75 amps, so you must use a 50-amp breaker with 8-gauge wire. The unit sits on adjustable legs, allowing you to level it on the sauna floor. This base design ensures stability without needing complex mounting hardware. The heater measures 22 inches in diameter and 29.5 inches tall, fitting standard sauna footprints. You also need space for the UKU extension box, which adds seven inches in width and ten inches in height.
Daily operation relies on the WiFi UKU control system. This interface lets you manage settings remotely through a glass panel. You can adjust temperature and timing from outside the sauna room. The air tunnel design shortens heat-up time, so you spend less waiting and more using the space. The stainless steel elements are industrial quality, which helps extend the life of the heater during frequent use.
The heater holds 550 pounds of rounded olivine diabase stones. These stones have a high heat capacity and sit directly on the heating elements. This direct contact creates a longer, milder heat experience compared to traditional setups. The rounded shape complements the heater’s design while ensuring even heat distribution. You simply load the stones according to the manufacturer’s guidelines. The combination of WiFi control and efficient stone placement makes daily use straightforward for larger sauna rooms.
Before You Buy This Heater
You must ensure your sauna room falls between 636 and 1,236 cubic feet. This 18 kW unit is too powerful for small spaces and too weak for larger ones. Verify your room dimensions precisely. The heater requires a dedicated 240-volt, single-phase circuit with a 50-amp breaker and 8-gauge wire. Do not attempt to install it on standard household outlets. You will need to purchase the olivine diabase stones separately if not included in your specific bundle, though the listing notes 550 pounds are included. The WiFi control uses a glass panel. If you prefer wood, check for the alternative variation. Regular maintenance involves cleaning the stainless steel exterior and checking the heating elements. This model sits alongside other options based on your power needs and control preferences. It suits those who want direct stone contact and industrial-grade heating elements. Skip it if your electrical setup cannot support the 75-amp draw.
Check before you buy
- Verify your sauna room is between 636 and 1,236 cubic feet.
- Confirm you have a 240V single-phase circuit with a 50-amp breaker.
- Check that your electrical panel can handle 8-gauge wire.
- Decide between the glass or wood WiFi control panel option.
