Quick answer
Can I use a desk heater in an office? Check your workplace's rules on personal heaters; many offices require PAT testing.
Why a desk heater beats turning the heating up
If you work from home, heating the whole house from 9 to 5 for one person is expensive. A desk heater warms just you.

Under the desk or on top?
On the floor under your desk warms your feet and legs; on the desk warms your hands and upper body. Either way, keep cables, papers and bags clear of the outlet.
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.
