Who it fits
Good fit for
You should choose this heater if you have a small sauna room between 106 and 247 cubic feet. The 4.5kW output is sufficient for those dimensions. It fits well in tight spaces due to its wall-mounted design. You will appreciate the WiFi control if you want to manage settings remotely. The included stones and sensors make installation straightforward. This model is ideal for users who prefer a clean, industrial look in their sauna.
Who should skip it
Skip this model if your sauna room exceeds 247 cubic feet. You will need a higher kilowatt rating for larger spaces. The 4.5kW unit is not suitable for rooms above that volume. You might also look elsewhere if you prefer a mirror or wood finish over the stainless steel option. The included 5-year warranty excludes elements, so check if that matters to you. Larger rooms require the 6kW, 7.5kW, or 9kW variants for proper heating.
Verdict: This heater offers efficient heat for small rooms with convenient WiFi control. It is a solid choice for compact sauna setups.
Key specs explained for you
Heater Power: 4.5 kW
This power rating determines how quickly the sauna reaches your desired temperature. A 4.5 kW unit is suitable for smaller rooms between 106 and 247 cubic feet. You will need this specific capacity to ensure the heater can warm the space efficiently without straining the system. Larger rooms require higher wattage to maintain consistent heat levels during use.
Voltage: 240V
The heater requires a dedicated 240-volt electrical circuit to operate safely. You cannot plug this unit into a standard 120-volt household outlet. Your electrician must install the correct wiring, typically 10 AWG, and a 30-amp circuit breaker. This high voltage ensures the heating elements receive enough energy to function at their full rated capacity.
Control Type: WiFi app, control display panel
You can manage the sauna settings using either the physical display panel or a remote WiFi application. This dual control allows you to start or adjust the heater from outside the room. The app offers convenience for scheduling, while the panel provides direct access to settings. This flexibility suits users who prefer remote management or direct manual input.
Dimensions: 15.4 x 13.2 x 23.3 in
These compact dimensions indicate a wall-mounted design that saves floor space. The unit fits well in smaller sauna rooms or tight corners. You must ensure your sauna walls can support the mounted weight and provide adequate clearance for ventilation. This size is ideal for users with limited square footage who still want a full-featured heating system.
Stainless Steel construction
The heater body is made from industrial-quality stainless steel, which resists corrosion and withstands high humidity. This material choice ensures durability and a clean aesthetic that complements modern sauna designs. You benefit from a long-lasting unit that does not rust or degrade over time, even with frequent use and exposure to steam and water splashes.
Materials, Size, And Controls
The listing states the heater uses stainless steel construction with industrial quality heating elements. This material choice suggests durability and resistance to corrosion in high humidity environments. You will appreciate the wall-mounted design, which saves floor space. The unit measures 15.4 inches wide, 13.2 inches deep, and 23.3 inches high. These dimensions allow for flexible placement in compact sauna rooms. The compact footprint ensures it fits into smaller enclosures without overwhelming the space.
Control options include a WiFi app and a physical control display panel. The display measures 4.13 by 2.17 by 0.87 inches. You can manage settings remotely via the app or directly from the panel. The package includes a temperature sensor, door sensor, and necessary cables. The temperature sensor cable is 9.84 feet long. The door and temperature sensor cables are 16.4 feet long. This wiring length gives you flexibility in sensor placement. You can position sensors away from the heater for accurate readings. The unit is designed, engineered, and made in Estonia. This origin indicates specific manufacturing standards. The finish is stainless steel. You get a clean, modern look that matches various interior styles. The included sauna stones complete the setup. You do not need to purchase them separately.
Setup and everyday use
Setting up this heater involves mounting the unit to your sauna wall using the included bracket. You must connect the 240V power supply using 10 AWG wire. The listing specifies a 30-amp circuit breaker is required for this 4.5 kW model. You will also need to install the control display panel, which connects via a 9.84-foot cable. The temperature sensor and door sensor require their own 16.4-foot cables. These sensors allow the system to monitor conditions and detect when the door is open. The control panel measures 4.13 by 2.17 inches, making it compact for wall placement.
For daily use, you can control the heater through the UKU WiFi app or the physical display panel. The WiFi feature allows you to start the sauna remotely. This means you can preheat the room before you enter. The direct contact design between stones and heating elements affects how heat is distributed. More exposed stones create a milder heat experience that lasts longer. You do not need to manage complex settings manually. The app handles the timing and temperature adjustments. The stainless steel construction requires minimal maintenance. You simply add water to the stones when desired. The included sauna stones are ready for immediate use after installation. The system is designed to be straightforward once the electrical connections are secure. You benefit from precise control over your sauna environment without complicated manual overrides. The integration of sensors ensures safety by monitoring door status and internal temperature.
Check Compatibility Before Buying
Before you buy, verify your sauna room volume falls between 106 and 247 cubic feet for the 4.5 kW model. You must ensure your electrical panel supports a dedicated 30-amp breaker and 10 AWG wiring. The control panel requires a 9.84-foot cable run, so check your wall layout for clear paths. You will need to source sauna stones separately if not included in your specific bundle. Consider the 6 kW or 7.5 kW variants if your space exceeds 247 cubic feet, as the 4.5 kW unit will struggle to heat larger volumes efficiently. The WiFi app allows remote control, but you should test your sauna’s Wi-Fi signal strength first. This heater fits well in compact, modern setups where space is limited. Its wall-mounted design saves floor area, making it ideal for small homes. However, if you prefer traditional stone layouts, this direct-contact design offers a different heat profile. Always match the kilowatt rating precisely to your room size for optimal performance and energy efficiency.
Check before you buy
- Verify room volume is under 247 cubic feet
- Confirm 240V power with 30-amp breaker availability
- Check Wi-Fi signal strength inside the sauna room
- Ensure 9.84-foot cable reach for control panel
