My electric heater uses 2000 watts but if I leave this on for an hour how much would I actually use. I have solar panels but because of the weather they are not getting enough charge, can someone explain the equation to me how many watts in a kW and how long before something uses 1 kw
Are you a tradesperson and able to answer this question?

There are 1000W in a 1kW therefore a 2kW heater is rated at 2000W
If one has a 2kW heater one uses 2kWh every hour it is on, if it is on for 6 hours you have used (nominally) 12kWh
A solar panel is normally rated at 500W (ish) note though they all vary, but that is a maximum output, at the right angle in the height of summer.
The output of the bank of panels is a simple sum, if you have a readout somehow then you should be able to see if you have enough juice from the panels to power the heater.
Hope that helps?

1KW =1000 Watts. Depending on the electrical load of the appliance being used although heaters are normally thermostaticly controlled so when room reaches temp required they will knock off automatically, this makes it difficult to calculate exactly your usage as it be going on and off intermitenly.
