The power of convection radiators is mentioned in Dt50 which means the power emitted by the radiator when there are 50C difference between radiator and ambient (eg radiator at 70C, ambient at 20C, Dt=50C). I also have a small, electrical radiator on wheels, which is 2000 watts. It is about 1/3 of the size of the large radiators, all of which are listed as 1500-2000 watts (at Dt50). I suspect that the Dt50 power of convection radiators is not equivalent to the power of the electrical radiator. Would anyone know how to compare the two power ratings? |

All I know, through experience, is that no modern store heater can touch my old Soviet heater at 2 killowatts, 2 bulbs, 1 killowatt each. Nothing comes close. So they must be lying somehow on their specs. Tested in cold winters. |

Do you have a way to measure temperature ? Even like how long it takes to heat up a glass of cold water in front of it, up on some block of wood or something ? |

They theoretically have power they claim. However thermal switch will disconnect part of heating elements when it gets hot, so it will consume rated power only for a few minutes. So your 2000W heater will suddenly become 650W. |

I remember elderly relatives who would turn on just the red lamp in there fire to take the chill out the room |
