Let's compare a 1kW fan heater and a 1kW oil filled radiator.
Both get the area around the heater up to the temperature set by the thermostat.
The fan heater stops, and heat emission stops dead. The temperature reduces to the "turn back on" level and heat generation recommences at full pelt.
The oil filled heater stops, and heat emission continues. The temperature slowly reduces to the "turn back on" level
Actually the temp probably overshoots as the hot oil continues to heat the room after the power shuts off.
One is lown background heat, the other is quick localised heat. Now ideally you'd run your oil filled heater from heat pump as the instant hit isn't required, but that would be expensive, and they'd need to be bigger
