Quick answer
Are fan heaters expensive to run? They use electricity at their rated wattage while heating. Because they warm you up fast and can be switched off sooner, they're often cheaper in practice for short sessions than heating the whole house.
How a fan heater works
A small fan draws cool air in, pushes it across a heating element and blows warm air into the room. Because it moves air actively, you feel the heat within seconds rather than waiting for a radiator to warm up.
Ceramic vs wire-element fan heaters
Older fan heaters use bare coiled wire that glows red-hot. Ceramic PTC fan heaters use ceramic plates whose resistance rises as they heat, so they naturally limit their own temperature. That makes them a popular choice for homes with children and pets.

Where Keilini Heater Pro fits
Keilini Heater Pro is a compact ceramic PTC fan heater. It starts producing warm air in around 3 seconds, spreads it through a 90° grille, and runs at roughly 36–45dB. A built-in thermostat holds your chosen temperature, a tip-over switch cuts power if it is knocked over, and a timer switches it off after 1–12 hours.
It is designed to warm the room you are in — not to replace central heating for a whole house.
