Model note

What the EOS Saunadome II is

The Saunadome II is tower-shaped, with the stone chamber open on all four sides. A 100 × 41 × 41 cm body takes 100 kg of sauna stones; that mass carries the temperature and delivers strong löyly whichever side the water is poured from. The corner profiles are cut at an angle, so even small stones do not fall out. The body is entirely stainless steel, the corner profile is anthracite pearl effect, the top cover is brushed stainless and the feet are adjustable. Because every face is identical, it can be placed in the centre of the cabin or in front of glass. There are four ratings, from 9 kW for 9–14 m³ up to 18 kW for 24–30 m³; every rating except 9 kW requires a PEB 10. The air inlet and outlet cross-section must be at least 300 cm².

Close alternatives we also supply and install: the EOS Pipe (3 kW · 3.5 kW), the EOS Majesty (6 kW · 8 kW · 10 kW), the EOS Structure (6 kW · 8 kW · 10 kW · 12 kW). It belongs to the EOS Sauna Heaters. The EOS overview lists every range.

Selection

How we find the right capacity

We work out the capacity from the cabin volume; the five steps below are done together at the quotation stage.

Start with the cabin volume

Basic rule: cabin volume (m³) × 1 kW. A 2 × 2 × 2.10 m cabin is 8.4 m³ and needs about 9 kW. This figure is a starting point, not the answer.

Add glass and uninsulated surfaces

Add 1.2 m³ to the volume for every m² of glass front, and about 1.2 m³ for every m² of uninsulated concrete or stone. In a cabin with a full glass front, the real requirement is thirty to forty percent above the bare volume.

Agree the power supply early

Above 9 kW a 400 V three-phase supply is required; for lower outputs the phase is chosen according to the heater's installation manual. The heater is fed on its own circuit, with its own fuse and residual current device.

State the usage intensity

A home cabin used two hours a day and a hotel cabin open for ten hours cannot use the same unit. For commercial use, heavy-duty (HD) units and a larger stone mass are chosen.

Choose the control together with the heater

The power a control unit can switch directly is limited; above that, a PEB power boost unit is needed. This is calculated at the quotation stage.

Why EOS

Five series, one ecosystem

The logic you set up in a home works in a hotel too.

Five series, one control family

The same control family runs from the Standard series up to the large commercial series. The logic you set up in a home works in a hotel too.

Modular control

Sauna, hammam, steam and infrared modules plug into the EmoTouch 3 unit. Four rooms are run from one panel, with no separate switchboard.

Open to building automation

With the KNX and Modbus module it connects to the hotel management system, and opening hours can be programmed centrally.

Safety as a separate line

Door contact, emergency button, heater guard and EOSafe are available as separate products. In a commercial facility they are not optional.

Spare parts stock

We keep spare parts in stock in Istanbul for the equipment we install. In a commercial facility, what keeps a cabin closed for months is waiting for parts.

Around 20 years with EOS

We have been installing EOS equipment for around 20 years, so we know from site work how each unit performs in each room volume.
