ROC JM Mini Sauna Heater (Built-in Control)

The ROC JM Mini Built-in Sauna Heater is a compact heater designed for very small saunas. The built-in control JM adds timer and thermostat controls to the heater body, giving a small sauna a complete heating system in one unit with no external panel to mount. Casing: full stainless steel casing with wooden guard rail.

Because the controls are built in, this mini heater is one of the easiest ROC units to install. There is no separate control box to wire or mount on the wall, which saves both cost and installation time. This makes the Mini Built-in Sauna Heater a smart choice for compact home saunas, apartments, guest rooms and cabins where wall space is limited.

2 models cover sauna rooms from 2 to 4 m³: JM-30BS (3.0 kW) for 2–4 m³ and JM-36BS (3.6 kW) for 3–4 m³. Choose the model whose published room volume range contains your room; if the room sits at the top of a range, step up one size. The low 3–3.6 kW power draw means these heaters work on standard home wiring without a heavy-duty circuit upgrade.

All ROC heaters run on 220–240 V single-phase or 380–415 V three-phase supply and are CE marked as standard; UL certification for North America can be arranged on request, with the cost quoted per project. The JM mini built-in-control heater is an ROC own-brand product and can be supplied under your brand through our OEM and ODM service. See the full ROC JM Mini Heaters range. Typical use: compact home saunas, guest rooms and cabins where wall space is limited.
