Typically the heat range for NGK Spark Plugs varies from 2-11. This number indicates the thermal characteristics of a spark plug, or how 'hot' or 'cold' a spark plug is. The term hot/cold is commonly used to describe whether a spark plug heats up easily (hot) or whether it provides resistance to heating up (cold).

The heat range has nothing to do with the actual voltage transferred through the spark plug. Rather, the heat range is a measure of the spark plug's ability to remove heat from the combustion chamber.
Bosch glow plugs get to the point quickly: The startup times of modern diesel engines are correspondingly short Heating-up diagrams: Duraterm and DuraSpeed The right solution for every diesel engine The comprehensive range of sheathed-element glow plugs from Bosch provides the right solution for almost every diesel vehicle - even for older cars.
A spark plug is said to be "hot" if it is a better heat insulator, keeping more heat in the tip of the spark plug. A spark plug is said to be "cold" if it can conduct more heat out of the spark plug tip and lower the tip's temperature. Whether a spark plug is "hot" or "cold" is known as the heat range of the spark plug.
Why do diesel engines require glow plugs and what function do they perform? Answer Unlike gasoline engines which use a spark plug to ignite an air/fuel mixture, diesel engines rely on the heat of highly-compressed air to ignite a precise amount of fuel to initiate combustion. Heating the air to a minimum

Glow plugs are specialized heating devices used to aid in the starting of diesel engines. They are similar to spark plugs in design; however, they differ in their primary function. Instead of producing a timed spark to ignite the fuel mixture, like spark plugs do, glow plugs simply serve to produce additional heat that aids the diesel engine ...
body, the heating rod with the heating and regulating coil and the connection bolts. The non-corrosive glow tube is pressed into the housing gas tight. Additionally, the plug is sealed to the connecting point by an O-ring or a plastic part. The glow plugs take their electrical energy from the battery.
