The Princess Glass Smart Panel Heater is our best value smart pick because it brings genuine smart-home control to an indicative £120 or so — well below the Dyson. The 2000W panel has two heat settings and an adjustable thermostat (up to 35°C), and suits small-to-medium rooms. Its standout is control: a HomeWizard app lets you set schedules so a room is warm before you get home, with Alexa and Google Assistant voice support, plus a touch screen, timer and child lock. It can stand on the included feet or wall-mount with the supplied bracket. The trade-offs versus the pricier picks are real — as a convection panel it doesn't hold heat like the oil-filled De'Longhi, and Princess doesn't carry the same long-term reliability reputation as Dyson or Herschel — but for scheduled, hands-off warmth in a bedroom, office or conservatory on a budget, nothing here matches its feature-per-pound value.

The good & the bad

Pros

  • App scheduling, voice control and a thermostat for an indicative £120 or so
  • Slim glass design that stands or wall-mounts with the included bracket
  • Touch screen, timer and child lock make hands-off heating easy

Cons

  • Convection panel doesn't retain heat once it switches off
  • Princess is a value brand without the long-term reliability record of Dyson or Herschel
