Ember Complete — Portable Gas Sauna Tent with Cedar Bench
Ember Base — Portable Gas Sauna Tent | Sauna-Ready in Under 20 Minutes
Steam & Oak is the first UK retail partner for FinSteam. A genuine Finnish sauna, sauna-ready in under 20 minutes — no fire to build, no smoke, no ash, no chimney to sweep. The Ember Base runs on a standard propane bottle and a genuine 8.1 kW gas heater, so you get deep, even heat at the turn of a dial. Light it, leave it, step in. The Base is our entry package: tent, gas heater, stones and gas kit, with floor seating — a camping-style setup you can add a bench to whenever you like. Why gas Sauna-ready in under 20 minutes — no long fire to coax, no tending mid-session. No smoke, ash or chimney sweeping — nothing to clean. Even, controllable heat — up when it's busy, down when it's idle. ~£2-£3 a session to run, with no electrician needed. Built-in safety — oxygen-depletion sensor, flame supervision and piezo ignition. Bottle stays outside; only the hose enters. Honest trade-off: it runs on LPG, you'll swap a gas bottle now and then, and ventilation is mandatory (it's built into the design). For anyone who just wants heat without the faff, it's ideal. A note on floor seating Heat rises, so sitting on the floor feels gentler than sitting up on a bench — perfect for beginners, families and cool-down sessions. A heat-resistant floor mat is included. Want the full 90–100°C bench experience? Step up to the Ember Complete, or add a folding cedar bench any time. What's included Fritid X sauna tent (black, two doors, connectable) Botnia 81 gas heater (8.1 kW) Orbis stone cage (holds the sauna stones) 40 kg sauna stones UK propane regulator + 1.2 m hose Heat-resistant floor mat Install & safety guide 12-month warranty Free UK delivery How the gas heat works — sauna-ready in under 20 minutes Electric and wood heaters warm the room indirectly: they heat a big mass of stones first, which slowly warms the air — 30 to 45 minutes of waiting or fire-tending. A FinSteam gas heater is flueless and heats directly: it burns gas cleanly and puts the hot air and water vapour straight into the cabin, while the stones still heat for löyly. Nothing is stored first, nothing is lost up a chimney — so it's sauna-ready in under 20 minutes, on a dial. It also carries a soft, natural humidity from the moment it lights. Full explainer: how a gas sauna heater works. Weighing up fuels? Wood-fired vs gas vs electric. Heat-up time is typical tent set-up (manufacturer guidance); varies with sauna size, insulation and ventilation. The science behind it — FinSteam's engineering framework Direct Thermal Flow™. Heat from combustion reaches the sauna air, the stones and the structure simultaneously, from the first minute — instead of being stored in a stone mass first and released slowly. Same physics as any sauna; a fundamentally different engineering configuration. Humidity Balance™. Clean LPG combustion continuously releases gentle water vapour into the cabin, so the sauna starts with a pleasant base humidity instead of the harsh dry heat before the first ladle. Löyly works exactly as normal — this sits underneath it, it doesn't replace it. Sauna Climate Engineering™. Heat, moisture, thermal storage, airflow and ventilation managed as one coordinated system — not one number on a dial. Why the kW number misleads An independent, FINAS-accredited energy laboratory (Kymenlaakso University of Applied Sciences, Finland) tested seven wood-fired sauna heaters rated ~20 kW: measured heat output was just 57–72% of the nameplate figure, with 28–43% of the heat going straight up the chimney. A FinSteam heater is flueless — there is no chimney to lose heat up, so virtually all combustion heat, including the latent heat carried in the water vapour, stays inside the sauna. That's why an 8.1 kW FinSteam outperforms its label — you can't compare nameplate kW across heater types. An 11 kg cylinder runs ≈ 18 hours at continuous full power — and real sessions use less, because full power is mainly for heat-up. Lab study source: TM Rakennusmaailma / Kymenlaakso UAS study of wood-fired heaters; FinSteam was not part of that test. FinSteam's trademarked engineering framework · EU Type Examination Certificate A01/002220 (AENOR) · EN 449 · Independently tested by Applus+ Laboratories. No electrician. No chimney. Off-grid. It runs on a standard propane bottle, so there's no electrician, no dedicated circuit and no Part P sign-off — the £800–£1,500 line item that catches out electric-sauna buyers. No chimney means no smoke and no problem in a smoke-control area. Propane keeps working through a British winter, so it's a genuine year-round, go-anywhere sauna. Running cost is about £2-£3 a session - nearer £3 on a portable 6 kg gas bottle, or £2-£2.50 on an economy 13 kg bottle. That's roughly level with an electric sauna: you choose gas for what it removes - the electrician, the wiring and the wait - not to cut your energy bill. The safety engineering Gas in an enclosed space deserves serious engineering. Every FinSteam heater has an Oxygen Depletion Sensor (ODS) that shuts
