What size room will 1200 W heat?

Roughly 10 to 12 square metres in a well-insulated room with standard ceiling height. Larger or draughty rooms will need a second unit or a higher-wattage model.

Does it need a plumber or special wiring?

No. It is an electric panel heater that plugs into a normal socket, though the 220 V rating means you should confirm it matches your home's supply. Wall mounting is a DIY job with a drill and the right fixings.

Can I control it when I am away from home?

Yes. The built-in Wi-Fi lets you set schedules and switch it on or off from the app, so you can warm a room before you arrive.

It is a fan-free convection heater, so there is no fan hum. You may hear slight ticking as the metal expands and contracts when it heats and cools.

Is it better than an oil-filled radiator?

It heats up faster and is slimmer on the wall, but an oil-filled radiator keeps giving off heat after it is switched off. For steady all-day warmth, oil-filled suits some rooms better.

What comes in the box?

The heater, wall-mounting bracket and fixings, and a power lead. A plug and the app setup instructions are included; a thermostat or timer is built in.
