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.
