How much space will 700W heat?

It suits a small room such as a bedroom, office or bathroom. It will not keep a large or open-plan room warm on its own.

No. There is no fan, so the only sound is a faint tick as the thermostat switches.

Can I leave it running unattended?

It has a thermostat, timer and overheat shut-off, but most makers advise against leaving any heater running unattended for long periods.

It arrives mostly assembled. You attach the feet and casters, then stand it upright before plugging it in.

At about 5.8 amps it runs on a standard 15-amp household circuit. Avoid sharing that circuit with other high-draw appliances.

It has overheat protection and a flame-retardant shell, but the fins get hot. Keep it out of reach and clear of curtains and furniture.
