The cage is what holds the sauna stones in position above the burner — stones aren't just decoration, they're the thermal mass that gives you löyly when you ladle water on them.

Remove the wood stove and its flue, seal the flue penetration in the roof, fit the Botnia 81 on a non-combustible base in the same position (the sauna will already have approximately the right airflow because it was designed around the wood stove). You'll need to fit FinSteam-spec natural ventilation if the existing vents are mechanical \/ closable plastic disc types. Most barrel sauna conversions need the R11S configuration (Njord heat shield to reduce the clearance to the curved timber walls). Send us a photo of your barrel before you order — we'll tell you what you need.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eMy electric sauna heater has died.

Remove the old electric heater and its wiring (electrically isolate properly). Fit the Botnia on a non-combustible base — most electric saunas already have the right base. You'll need to add a wall gland for the gas hose, and provide natural ventilation if the existing was mechanical. The cabin's existing insulation works fine for gas — you're just changing the heat source.

If you use it portably (heater stands on the base, propane bottle outside, gas hose runs through a wall gland) — no, you don't. If you permanently fix the heater into the sauna structure (anchored, gas line routed and fixed) — yes, UK regulations require a Gas Safe registered engineer for the gas connection.

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.\u003c\/p\u003e\n\n\u003ch2\u003eThe safety engineering\u003c\/h2\u003e\n\u003cp\u003eGas in an enclosed space deserves serious engineering. Every FinSteam heater has an \u003cstrong\u003eOxygen Depletion Sensor (ODS)\u003c\/strong\u003e that shuts the gas off automatically if oxygen drops too low, \u003cstrong\u003eflame supervision\u003c\/strong\u003e that cuts the gas the instant the flame is lost, and push-button piezo ignition. The cylinder always stays outside — only the hose enters — and correct ventilation is part of every install. EU type-examination certified under the Gas Appliance Regulation (2016\/426).\u003c\/p\u003e\n\n\u003ch2\u003eWhy gas wins in busy and commercial saunas\u003c\/h2\u003e\n\u003cp\u003eThe hardest thing for any public or mobile sauna is the door: every time it opens, hot air escapes and cold pours in. An electric or wood heater then sags while it slowly rebuilds heat from the stones. A flueless gas heater produces heat \u003cem\u003econtinuously\u003c\/em\u003e and replaces the lost hot air the moment it escapes — so it holds temperature through constant use. It's why a well-specified 8.1 kW FinSteam heater keeps up where you'd expect to need far more power.

The Aurora is FinSteam's newer line — modern aesthetic, broader sauna-type adaptability, intended for builds where the heater is part of the design. The chassis, power, certifications, ODS, flame monitoring, heat-up time, gas consumption and löyly response are identical. \u003cstrong\u003eYou're paying for the design, not the heating capability.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eI have a glass-fronted cabin sauna. Is the Aurora the right pick?\u003c\/strong\u003e\u003cbr\u003eYes — this is one of the scenarios where Aurora's design language pays off. The heater will be visible through the glass, so the modern finish reads better than the Botnia's workhorse aesthetic. The R14S is typical for premium glass-fronted retrofits — the safety pack is what most professional installers expect to see on the visible heater.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eI'm replacing a tired electric heater in my existing cabin. Botnia or Aurora?\u003c\/strong\u003e\u003cbr\u003eFunction-wise, identical. Aesthetic-wise, depends on your cabin. If the cabin is a quality build (cedar, hemlock, designed sauna), the Aurora justifies the £200-300 premium per variant. If it's a budget cabin where the heater isn't on display, the Botnia is the smarter buy.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eI have an existing wood-fired sauna. Can I convert it to Aurora?\u003c\/strong\u003e\u003cbr\u003eYes — same retrofit process as a Botnia conversion. Remove the wood stove + flue, seal the roof penetration, fit the Aurora on a non-combustible base. Add FinSteam-spec natural ventilation if needed (wooden louvres, sized per spec). The R14S is the typical premium conversion configuration.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWill it fit my barrel sauna?\u003c\/strong\u003e\u003cbr\u003eAlmost certainly — the standard 200 mm side clearance fits most barrel saunas. For the tightest installs, the Njord heat shield (R14S) brings the required side clearance down to 50 mm. Send us a photo of the barrel before you order.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo I need a Gas Safe engineer?\u003c\/strong\u003e\u003cbr\u003eNot for portable use (heater stands on the base, bottle outside, hose through a wall gland).

FinSteam specify wooden louvre vents: ≥350 cm² intake near the heater, ≥250 cm² exhaust in the opposite high corner, both drawing fresh air from outside and discharging to outside. If your existing vents don't match this, you'll need to retrofit them before the heater can be used.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I run the Aurora 81 in a FinSteam Fritid X tent?\u003c\/strong\u003e\u003cbr\u003eYes — the Fritid X is engineered for the same 8.1 kW heater chassis.

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.\u003c\/p\u003e\n\n\u003ch2\u003eThe safety engineering\u003c\/h2\u003e\n\u003cp\u003eGas in an enclosed space deserves serious engineering. Every FinSteam heater has an \u003cstrong\u003eOxygen Depletion Sensor (ODS)\u003c\/strong\u003e that shuts the gas off automatically if oxygen drops too low, \u003cstrong\u003eflame supervision\u003c\/strong\u003e that cuts the gas the instant the flame is lost, and push-button piezo ignition. The Aurora adds an integrated \u003cstrong\u003e60-minute safety timer\u003c\/strong\u003e that shuts the heater off automatically — standard on every NOIR and commercial package. The cylinder always stays outside — only the hose enters.

An electric or wood heater then sags while it slowly rebuilds heat from the stones. A flueless gas heater produces heat \u003cem\u003econtinuously\u003c\/em\u003e and replaces the lost hot air the moment it escapes — so it holds temperature through constant use. It's why a well-specified 8.1 kW FinSteam heater keeps up where you'd expect to need far more power.

The 3-layer fabric (Oxford 420D outer, 150 g\/m² fibre fill, Oxford 210D inner) holds combustion heat the way a wooden cabin does for the same internal volume. The FinSteam 8.1 kW heater produces authentic Finnish löyly when you ladle water on the stones. After one session people stop asking the question — the experience is indistinguishable from a fixed Finnish sauna at the same volume.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAre portable saunas worth it for UK use?\u003c\/strong\u003e\u003cbr\u003eFor most UK gardens, yes — a portable gas sauna is the most cost-effective way to get a real Finnish sauna experience without building a permanent cabin. You skip the electrician (no consumer-unit upgrade), the chimney, the planning permission battle, and the £8,000-£30,000 price tag of a fixed sauna. The Fritid sets up in under a minute, heats in 15, and packs down to a carry-bag between uses.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow long does it take to set up and to heat up?\u003c\/strong\u003e\u003cbr\u003ePitch in under a minute (integrated frame, no tools). Heat from cold to 70-75°C in 15-20 minutes with the FinSteam heater. Compared to wood-fired portable saunas that take 30-45 minutes to warm up, the gas heat-up time alone is the deciding factor for most buyers.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs it safe to run a gas heater inside a sauna tent?\u003c\/strong\u003e\u003cbr\u003eYes — and the safety case is engineered, not improvised. The Fritid ships with the ventilation already designed-in by FinSteam — you do not add or modify ventilation. The vent openings are sized to match the heater's airflow and the combination is certified together under EU Gas Appliance Regulation 2016\/426. The heater itself has an Oxygen Depletion Sensor that cuts the gas at approximately 18% oxygen, and flame monitoring that cuts the gas instantly if the flame is lost. Standard residential CO alarms aren't designed for sauna conditions (high temperature + humidity) — the ODS auto-shutoff is the engineered safety solution, and a CO alarm is not necessary when the tent is used as supplied.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo I need a Gas Safe engineer?\u003c\/strong\u003e\u003cbr\u003eNo, not for portable use. The heater runs as a portable LPG appliance — propane bottle outside, UK 37 mbar regulator, CE-marked hose, connected like a patio heater. You only need a Gas Safe registered engineer if you choose to fix or build the heater into a permanent structure.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I use it in winter?\u003c\/strong\u003e\u003cbr\u003eYes — year-round use is exactly what it's designed for. The 3-layer insulation plus the 15-minute heat-up means UK winter is a non-issue. The 2000 mm waterproof rating handles rain and snow. Pack down between sessions if you're leaving it pitched long-term in heavy weather. Many UK owners run sauna + cold plunge contrast sessions through the winter — which is when most people want a sauna anyway.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow does the Fritid compare to the Fritid X?\u003c\/strong\u003e\u003cbr\u003eFabric construction, insulation, ventilation, dimensions and heater compatibility are identical.

Both tents seal at the connection. Heat retention in the sauna tent is identical to a standalone Fritid X. The connection is built-in — no separate tunnel piece needed, no fiddly assembly. Pitch both tents, line up the connecting entrances, fasten — done.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo I need two tents?\u003c\/strong\u003e\u003cbr\u003eNo — most owners start with one and add a second later. The Fritid X works perfectly as a standalone portable sauna for 2-4 people. Both entrances seal fully when only one tent is pitched. The second entrance simply opens the upgrade path later, with no special connector kit required.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs it safe to run a gas heater inside the Fritid X?\u003c\/strong\u003e\u003cbr\u003eYes — and the safety case is engineered. The Fritid X ships with the ventilation already designed-in to match the FinSteam heater's airflow, the combination certified together under EU Regulation 2016\/426. The heater itself has an ODS auto-shutoff at approximately 18% oxygen, and flame monitoring. Standard residential CO alarms aren't designed for sauna conditions — the ODS is the engineered safety solution.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo I need a Gas Safe engineer?\u003c\/strong\u003e\u003cbr\u003eNo, not for portable use.

The 3-layer insulation plus the 15-minute heat-up means UK winter is a non-issue. The 2000 mm waterproof rating handles rain and snow. The two-tent setup is especially good in winter because you get changed in the warm of the second tent.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs the Fritid X good for commercial \/ mobile sauna hire use?\u003c\/strong\u003e\u003cbr\u003eYes — it's the configuration most UK mobile sauna hire operators choose for a flagship single-unit setup.

The Dome isn't a single-heater tent that \"can take a second heater\" — it's a tent designed around the pair from day one, certified that way under EU Regulation 2016\/426.

The 10-14 person capacity, the no-electricity \/ no-flue setup, the rapid pitch-and-pack-down, and the heater certification make it the most rentable sauna unit FinSteam make. UK rental operators typically charge £15-25 per head per 45-60 min session, putting a busy Dome at £150-£350 per session and £600-£1,500 per event day.

Yes if you fix or build the heaters into a permanent commercial structure, in which case UK regulations require a Gas Safe registered installer.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow long does the Dome take to heat up, and what's the running cost?\u003c\/strong\u003e\u003cbr\u003e15-20 minutes from cold to sauna temperature with both heaters running. Combined gas consumption ~1.2 kg\/h (0.6 kg\/h per heater at full power). A standard 13 kg UK propane bottle runs the Dome at full output for ~10 hours; throttled at temperature, much longer. At current UK propane prices (~£40 per 13 kg bottle), running cost per session is materially below what operators charge per head, leaving healthy margin.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs it safe — and what about CO inside a sauna with two heaters running?\u003c\/strong\u003e\u003cbr\u003eYes. The tent ships with ventilation engineered specifically for the dual-heater configuration — you don't modify it. Each heater has an ODS auto-shutoff (~18% oxygen) and flame monitoring. Standard residential CO alarms aren't designed for sauna conditions (high temperature + humidity) and won't operate reliably inside; the ODS is the engineered safety case. For commercial venue approvals, we supply EU Type-Examination Certificate + Declaration of Conformity on request — venues' fire-risk assessors ask for both.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWill festivals and venues actually approve a gas sauna on site?\u003c\/strong\u003e\u003cbr\u003eGenerally yes — and faster than they'd approve a wood-fired one. The certified ODS auto-shutoff, no open flame, no chimney, and the freestanding portable status all simplify the venue's fire-risk assessment. We can supply venues with the EU Type-Examination Certificate, Declaration of Conformity, and a one-page operations brief for their RA file.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow does the Dome compare to the NOIR XXL Signature two-tent setup?\u003c\/strong\u003e\u003cbr\u003eDifferent products for different use-cases.
