FAQs

What size heater do I need for my sauna?

Calculate the interior volume of your sauna room in cubic metres (length × width × height). As a general guide, allow approximately 1KW per 1.5–2 cubic metres. For outdoor saunas or rooms with large windows or glass doors, add 20% to account for heat loss. Use our Heater Size Guide above to match the right heater to your space.

Why choose a cylinder heater over a rectangular heater?

Cylinder heaters offer several advantages. The vertical design holds significantly more stones (50–80kg vs 18–22kg), creating better thermal mass for softer, more consistent heat. The larger stone mass also produces superior löyly (steam) when water is poured over it. The striking tower design creates a visual centrepiece in your sauna, and the circular profile allows efficient air circulation.

How much space does the cylinder heater need?

The heater has a 38cm diameter footprint and stands 80cm tall. Allow adequate space around the heater for air circulation and safety. Maintain a minimum 40cm clearance between the top of the heater and the ceiling. Floor mounting is recommended.

How does the Wi-Fi control work?

The system includes a compact wireless adapter that plugs into the controller. Once connected to your home Wi-Fi network, you download the free app to your smartphone. The app lets you turn the sauna on/off, set the temperature, adjust the timer, and monitor current conditions from anywhere with internet access.

Is the Wi-Fi system complex to set up?

Not at all. The adapter plugs directly into the controller and connects to your Wi-Fi network like any smart home device. The app guides you through pairing in a few minutes. No technical expertise or professional setup required.

Can I still use the wall controller if the Wi-Fi is down?

Yes. The external wall controller works independently. Wi-Fi adds remote convenience, but the physical controller provides full functionality at all times, even without an internet connection.

Can I install this heater myself?

The heater requires professional electrical installation by a licensed electrician. While positioning the heater and setting up Wi-Fi is straightforward, connecting to your electrical supply must be done by a qualified professional to ensure safety and compliance with Thai electrical regulations.

How long does the heater take to warm up the sauna?

Expect 30–45 minutes to reach typical sauna temperatures of 80–90°C, depending on room size, insulation quality, and ambient temperature. The larger stone mass may take slightly longer to reach a uniform temperature, but it retains heat better during sessions.

Are the sauna stones included?

Yes. Each heater includes 50–80kg of premium sauna stones (shipped in 4 boxes). These volcanic stones are explicitly selected for sauna use and can withstand thermal shock from water contact without cracking.

What electrical supply do I need?

The heater operates on standard Thai 220–240V single-phase power. You will need a dedicated circuit with appropriate amperage (typically 30–40A, depending on heater size) and a correctly rated MCB. Your electrician will assess your electrical panel’s capacity.

Can I use this heater for an outdoor sauna?

Yes, but the heater itself must be installed inside the sauna room, protected from direct weather exposure. For outdoor saunas, choose a heater size 20% larger than the room volume calculation suggests to compensate for heat loss.

Is this heater suitable for commercial use?

Yes. The cylinder heater’s robust construction and large stone capacity make it well-suited for commercial applications, including wellness centres, spas, gyms, and hotels. The impressive design also enhances the aesthetic appeal of premium facilities.

What is the warranty?

Heaters include a 1-year manufacturer’s warranty covering defects in materials and workmanship. Warranty does not cover damage from improper installation, misuse, or normal wear of heating elements.
