EOS Sauna Heaters

36 modelsEOSSupply · Installation

Short answer: EOS Saunatechnik makes wall-mounted, tower and floor-standing sauna heaters, from home cabins to commercial saunas. Sauna Dekor sizes each heater against the cabin it builds, then supplies, installs and commissions it; the heater and its certificates are EOS's.

Sizing starts from the cabin volume. Harvia's published rule of about 1 kW per cubic metre, plus about 1.2 m³ for every square metre of glass, stone or concrete, gives the corrected volume, and the volume range EOS publishes for each output must contain it. A Finnish sauna then runs at 80–100 °C.

Use decides the body. A home cabin can take a standard wall heater; a hotel or gym sauna in use all day takes a duty-rated commercial body, and a concealed heater frees bench space. See our heater sizing guide and types of sauna heaters.

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.

Frequently asked questions

Does Sauna Dekor manufacture EOS heaters?

No. EOS heaters are made by EOS Saunatechnik in Germany. We manufacture the cabin and size, supply and install the heater in it.

How is an EOS heater sized?

From the corrected cabin volume, which must fall inside the volume range EOS publishes for each output. Glass, stone and concrete surfaces increase the volume used.

Which EOS heaters suit commercial saunas?

The duty-rated bodies of the commercial range, such as the 46.U, 46.U XL and 34.G HD; the choice follows the cabin size and hours of use.
