Model note

What the EOS Zeus HD is

The Zeus HD is the commercial-grade big brother of the Zeus S: the body is made of 8 mm steel, 70 cm in diameter and 125 cm high, weighing roughly 140 kg without stones. The low-bodied Zeus L HD is 70 × 79 cm. The stone chamber takes around 60 kg. Internal wiring runs on solid copper busbar; two connection cables with heavy-duty plugs are supplied with the unit. The 20 and 24 kW bodies ship with safety sockets, the 30 and 36 kW bodies with an additional stone frame. The 20 kW covers 24–30 m³, the 24 kW 35–40 m³, the 30 kW 50–65 m³ and the 36 kW 65–75 m³; 20–24 kW needs a PEB 18 and 30–36 kW a PEB 36. Finishes are "Rust Marble", matt black or anthracite pearl effect.

Close alternatives we also supply and install: the EOS Mega HD (36 kW · 42 kW · 48 kW · 54 kW · 60 kW · 72 kW), the EOS EmoTec (Control units), the EOS Compact DP / HP (Control units). 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.
