How to use a Stadler Form fan

Updated: October 2026

The unit is out of the box, and you want it on without drying a jumper on the grille or leaving a 2 kW heater to a plug-in timer. How to use a Stadler Form fan depends on which machine you own. A cooling fan wants a clear path for air. A fan heater wants a metre of space, a mode you set while you are in the room, and the off switch when you leave. The [Stadler Form fan](/hub/portable-heaters/stadler-form-fan) comparison is the model list. Products Compared editorial team, 16 October 2026. No lab test. Links may earn us a commission.

Put it down before you switch it on

Stand a fan heater on a flat floor, not on a chair or a deep carpet that can tip it. Hertfordshire Fire and Rescue asks for about one metre from anything that can burn, and for nothing drying on the heater. Curtains and a laundry rack are the usual mistakes. Stadler Form says these heaters should not be used below about 4 m² and should not be left running unattended. Do not block the intake against a wall, and do not aim a heater at bedding. If you are still unsure whether you bought a breeze or heat, the Stadler Form fan heater or fan page makes that split. The socket and the fuse are on the Stadler Form fan UK plug page.

Auto mode on Paul and Anna big

On Anna big, the manual starts with the main switch on the back, then On/Off. Auto mode shows a preset of 22°C. Output steps down as the room nears that target. If you change the power level by hand, you leave auto. When the target is reached, the element switches off and the fan may run on briefly. That run-on is in the manual. It is not the heater refusing to stop. Paul’s listing describes the same idea from the remote or the touch panel: the unit trims output instead of sitting at 2000 W all evening. Do not put Anna big or Paul on a plug-in timer overnight. The maker says Anna big must not run from a timer switch. Fan-only is for air movement while you are there, not a desk fan left on all day.

Sam’s app, Tim’s adapter, Otto’s grille

Sam joins only a 2.4 GHz network. The maker’s Wi-Fi page says a combined 2.4/5 GHz network, or 5 GHz alone, will not do. Pairing is a three-second press of the Wi-Fi button, with the phone’s Wi-Fi and Bluetooth on, in the Stadler Form app. There is no United Kingdom review of the app in this file. Tim runs from the maker’s adapter or from USB at 5 V and at least 2 A. Unplug it before you clean it. There is no battery in the bullets. Otto’s rear grille comes off so you can reach the blades. Older Ottos may not have the four screws, so do not force a cover that was not built that way. Dust the blades with the plug out. Do not wash the motor. If a new heater smells of burning, or the plug is hot, stop. That is a fault, not running-in.

When you stop and get help

Stop and unplug if a breaker trips as soon as you plug in, if the plug or socket is scorched or arcing, or if the fuse does not match the marking. One UK review of Otto describes a breaker trip. One UK review of Paul found a 3 A fuse in a plug marked 13 A. Do not run a 2 kW heater through a travel adaptor or a coiled extension reel. Paul’s maker page states IP21. Anna big’s page says it is not splash-proof, and the amazon file has no IP code. If you cannot match the room to the claim, do not place it beside a bath.

Common questions

How do I turn Anna big or Paul to auto?
On Anna big, use the main switch on the back, then On/Off, then Auto. The manual shows a preset of 22°C, and the output steps down as the room nears that target. Changing the power level by hand leaves auto. When the target is reached, the element switches off and the fan may run on briefly. Paul uses the remote or the touch panel for adaptive heat. Set it while you are in the room, and switch it off when you leave.
Can I put the heater on a plug-in timer overnight?
No. Stadler Form says Anna big must not be left unattended and must not run from a timer switch. Hertfordshire Fire and Rescue says turn a portable heater off when you leave or go to bed, unless the maker designed overnight use. Auto mode is a thermostat for a session you are awake for. It is not an overnight permit. A UK review also describes a harsh standby buzz on Anna big.
Why will Sam not join my Wi-Fi?
Sam is specified for 2.4 GHz only. A combined 2.4/5 GHz network, or 5 GHz on its own, is outside the maker’s Wi-Fi page. Hold the Wi-Fi button for about three seconds, with the phone’s Wi-Fi and Bluetooth on, and use the Stadler Form app. There is no UK review of that app in this file. If the router will not offer a plain 2.4 GHz network, the app cannot invent one.
How do I clean Otto or Tim?
Unplug first. On Otto, the rear grille comes off so you can dust the blades. If an older Otto has no screws for that cover, do not force it. On Tim, use only the maker’s adapter or a 5 V source of at least 2 A, and unplug before cleaning. Do not wash the motor. A heater’s inlet filter, where Anna big has a washable one, is a separate job from the fan blades.
Where does a professional take over?
Call an electrician for a scorched or arcing socket, a breaker that trips as soon as you plug in, or a bathroom circuit you cannot match to the IP claim. Do not change a fuse whose rating you are unsure of. A two-pin plug on a 2 kW heater is a reason to reject the goods, not a reason to fit a travel adaptor and carry on.
