It's roughly 1000 watts all together so does the watt usuage on the stuff mean per hour?
Hello; Yes I believe it does.
Hello; Let me take a stab at this. Bear in mind I slept in my recliner last night and not at a Holiday Inn Express.
So you are burning 1 kW ( 1000 watts) each hour = 1 kWh. That is 24 kWh each day. That is 168 kWh every seven days. That is 720 kWh every 30 days.
Lets figure at $ .1048 per kWh as this is the hobby on top of other electrical use.
720 times .1048 = $75.45 every 30 days = $905.47 or so each year .
I know power usage will vary with seasons and that has not been factored in. However much will depend on a couple of things. Your heaters should use less power during the summer as the ambient temperature is commonly warmer. (you do not list your location and I am assuming a temperate location.)
The however question is- Do you use AC to cool the house in the warm months? If so your heaters may cause the use of as much or even more electricity during the warm months than the cold months. How? Say the tanks are kept at 80 degrees F and the house is kept at 70 degrees F. This means the AC unit is fighting the tank heaters over this 10 degrees of warm water all cooling season long. So it may sort of even out year around.
