Energy Breakdown (Math geeks welcome)

[Vision Geckos]

I'm trying to figure out how much power it takes to use a couple different heating methods.

I'm looking for not just the wattage, but the amps, volts and MOST importantly the amp hours. I want to know just how much electricity heat cables use in a certain time span... say 6-12 hours, as well as UTHs.

Specifically, I'm looking to find the information about the 14.75 inch repti-heat cable and a 6x9 inch ZooMed UTH. I've looked online for specs for both of these but all I could find is the wattage and voltage. I found nothing about amps and nothing about amp hours.

Does somebody know any of the information I'm looking for?

The reason I'm trying to research this is because I'm also looking into solar energy to help cut costs. I know it is a money sink and probably won't yield much, if anything, but it's a good idea to know the specs for these heating methods regardless.

Call the manufacturer for each product you need specs on. Most electricians and even your power company will have the data you are looking for.

So, for DC or AC with a purely resistive load (like lights, and heaters):

Power(watts) = Voltage(Volts) x Current(Amps)
or... P = VI where, if you're running off your home grid in the USA, V = 120V

If you want to solve for current, then I = P / V

A Kilowatt-hour describes the amount of energy used, is calculated just like it looks ( E = Power x Time). A 1000 Watt (1 kilowatt) heater would use 1 kilowatt-hour of energy in an hour. ( E = 1 kilowatt x 1 hour = 1 kilowatt-hour) So a 20 Watt heater that ran for 1 hour would use 0.020 kilowatt-hours of energy. If it ran 24hrs a day it would use 0.48 kw-hrs / day, or 14.88 kw-hrs / month.

The discussion get's more complicated if you're using a thermostat or rheostat... we can get into that if you want.

Ohm's law will solve any of your questions, just google a converter and it will help you calculate based on your usage
