Instructions: How to find the right Sauna heater for your Celsium garden sauna
The right one Sauna heater heater is crucial for the overall sauna experience - it influences the heat quality, heating time and energy efficiency. So that you can exploit the full potential of your Celsium garden sauna, you will find a compact and well-founded guide to choosing the right heater here.
1. calculate the room volume correctly
First determine the internal volume of your sauna:
Width × depth × height = m³ (cubic meters)
Example for the Ula Micro: 1.35 m × 1.25 m × 2.30 m = approx. 3,9 m³
Important:
If your sauna has glass elements, thin outer walls or a free-standing location in the garden, you should also add approx. 1.5 m³ per square meter of uninsulated area should be added. This so-called insulation reserve compensates for heat loss.
2. choose the right heat output
The following applies as a guideline:
1 kW heat output per 1 m³ room volume
- For 4 m³ → ideally a stove with 4 kW
- For intermediate values, round up rather than down - so that your stove works reliably even at low outside temperatures
3. note the power connection
Depending on the model and output, there are two variants:
- 230 V connection (earthed plug) for compact sauna heaters
- 400 V three-phase current (heavy current) for more powerful models
Note: The connection must always be carried out by a qualified electrician.
5. control & comfort functions
Modern control systems not only offer temperature control, but also timer functions, app control and safety:
- Manual: classic rotary control module
- Digital: external control unit with precise temperature control
- SmartApp control via WLAN or 4G (e.g. HUUM UKU Wi-Fi)
