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)
 Infographic from FinA Wellness Store entitled "Competently chosen: The right heater for your cabin" - explains heat output according to room volume (1 kW per m³), additional requirements for glass surfaces (+1 kW/m²) and recommends a power reserve of 10-20% for outdoor saunas and solid wood cabins
