Romswi 1500W Oil-Filled Radiator Heater vs De'Longhi EW7707CM Oil-Filled Radiator Heater

Both are 1500W oil-filled radiators that heat quietly without a fan, so the choice comes down to controls and portability. The Romswi adds a digital thermostat, remote, 24-hour timer, child lock and five temperature settings, which suits bedrooms and timed schedules. The De'Longhi EW7707CM is the simpler, long-established unit with a proven track record and a slightly lower 700W low setting. Owners of oil-filled radiators in this class praise silent, steady heat and note slow warm-up; pick the Romswi for features, the De'Longhi for a no-frills, well-known design.

  • Choose the Romswi if you want a remote, a 24-hour timer, a digital thermostat and a child lock for scheduled, hands-off heating.
  • Choose the De'Longhi EW7707CM if you prefer a simple, well-known oil-filled radiator with a dial thermostat and no extra electronics.

Questions and answers

Which is better for a bedroom?
The Romswi, because the 24-hour timer and remote let you warm the room before bed and shut it off on schedule. The De'Longhi works fine but you set it by hand each time.
Which heats a room faster?
Neither is fast. Both are oil-filled radiators that warm up gradually and then hold heat. A fan heater heats a room quicker but is louder.
Which lasts longer?
The De'Longhi has the longer track record and a simpler control set, which usually means fewer parts to fail. The Romswi's electronics and remote add convenience but also more to go wrong.
Is the Romswi worth stepping up to over the De'Longhi?
If you want a timer, remote and child lock, yes. If you just want silent background heat with a dial, the De'Longhi covers it.
Do either have a fan?
No. Both rely on oil-filled fins and natural convection, so they are silent. Neither moves air the way a fan heater does.
Are they safe around kids and pets?
Both have tip-over and overheat protection. The Romswi adds a child lock on the controls. Either way, keep the hot fins out of reach.
