Model note

What the EOS Mythos is

Mythos is a cubic range and comes in two bodies: the S35 takes 35 kg of stones, the S45 takes 45 kg. Both are 37 cm deep — a narrow figure for that stone mass. The flat rear panel lets the heater sit in front of a glass surface or in the middle of the cabin. The S35 covers up to 14 m³ at 7.5 and 9 kW, the S45 up to 25 m³ at 12 and 15 kW; the 12 and 15 kW versions need a PEB 10. The evaporator can be added later: a 2 kW or 3 kW vertical unit measuring 84 × 8 × 37 cm sits alongside the body, works with a 10-litre tank and connects to the control unit with 5 × 1.5 mm² cable. Black, white, Water Reflection and dark bronze versions come with Cubius stones.

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.

Close alternatives: the EOS Zeus S, the EOS Morpheus Pro, the EOS Herkules S60.
