The Steam Butler is available in two sizes. Which one is right for your sauna depends primarily on one value: the power of your sauna heater. You can find this on the heater's nameplate or in its manual (specified in kW).
The rule of thumb
- Sauna heater up to 9 kW → Steam Butler Home
- Sauna heater over 9 kW → Steam Butler Maxi
The reason: A more powerful heater with more stones can evaporate more water per steam session. The Maxi therefore has a larger tipping container – and also a larger water tray, so that the supply still lasts for an entire sauna session.
Differences at a glance
| Home | Maxi | |
|---|---|---|
| Sauna heater | up to 9 kW | over 9 kW |
| Water tray | 1.2 liters | 2.2 liters |
| Tipping container | approx. 100 ml | approx. 150 ml |
| Steam session time per fill | 7–30 minutes | 9–30 minutes |
| Steam sessions per fill | approx. 17 | approx. 30 |
The material, scope of delivery and installation are the same for both: completely stainless steel, copper sealing rings, stainless steel chains and ceiling hooks. Installation takes about five minutes.
What happens if I choose the wrong size?
If the Steam Butler is too large for the heater, more water will hit the stones per steam session than they can evaporate – the water will then partially drip through. If it is too small, it is not a problem; you will simply get gentler steam sessions. If in doubt: Write the kW rating of your heater to us at support@steam-butler.de, and we will tell you which model is right for you.
