how many kcal/h is a 1000w electric heater
About 860 kcal/h (thermochemical): 1,000 W corresponds to roughly 859.5–860 kcal/h with this tool’s kcal/h factor (4,184 J per kcal over one hour).
Detailed answer
Convert watts to joules per second, then relate to kcal/h: this tool uses 1 kcal/h = 4,184/3,600 W. So kcal/h = W ÷ (4,184/3,600). A pure resistive heater converts essentially all electrical power to thermal power.
Relationship context
Some European thermal labels use kcal/h; electric ratings are often in W or kW. The conversion is linear once the thermochemical kcal definition is fixed.
