Frequently asked questions
A wall-mounted thermal-mass heater warms a room evenly and takes the place of a convector. A portable space heater plugs into an outlet and helps out in one room when you need it, with no installation and no electrician.
Mostly by not heating when there's no need: scheduling, away and open-window detection, and control from your phone. How much you save depends on your habits and how well your home is insulated.
A wall-mounted heater connects to a dedicated circuit, so hire a licensed electrician if you have any doubt. A portable heater such as the Mill Gentle Air WiFi simply plugs into an outlet; models sold in Europe are built for 230 V, so check that the version on your Amazon store is rated for 120 V.
