Ohm’s Law
The relationship between Wattage (heat) output and the applied Voltage of electric resistance heating elements is determined by a
precise physical rule defined as Ohm's Law which states that the current in a resistance heating element is directly proportional to the
applied Voltage. Ohm's Law is traditionally expressed as:
I = E/R
Where: I = Amperes (Current)
E = Voltage
R = Ohms (Resistance)
The same equation using the conventional abbreviation for voltage is:
I = V/R
Where: I = Amperes (Current)
V = Voltage
R = Ohms (Resistance)
An unknown electrical value can be derived by using any two known
values in one of the variations of Ohm's Law.

Heater Care And Information
Taking Care Of Your Heating System
Zone Control
Temperature Versus Cost
At the start of each heating season clean and inspect each heater. It is extremely important to remember to turn off the power at the circuit
breaker before attempting any installation, maintenance or repairs. Failure to do so may result in serious electrical shock, burns or
possible death. Remove the grille on fan heaters. Clean any dust or lint from inside the heater with a vacuum cleaner, compressed air or soft bristle
brush. Check that the fan spins freely. Between 5-10 years you may want to upgrade your thermostat, as the sensing element may not be as accurate
as when new. The most ac- curate thermostat is listed as an anticipated model. If, in the future, you decide to remodel or add rooms to your home, you
won’t have to worry about the size of your heating system. With electric heat you can add to the heating system, in large or small increments.
Thermostat settings are a matter of personal preference. A few days of adjustments will help you determine the setting that is comfortable for you. Most
people keep their living quarters at 68 to 72ºF (20 to 22ºC) and sleeping areas at 65ºF (18ºC). For energy conservation and financial savings it is wise to
set living area thermostats back at night, but not below 60ºF (16ºC).
When setting your thermostat, you may want to consider the relative cost of various temperatures. The chart at right shows how much higher your
heating bill may be if you like temperatures warmer than 70ºF (21ºC).
