3. Temperature Gradient - How Heat Sources Affect It.

The type of heat source you install can have a big impact on temperature gradient.

Stoves, cookers and panel radiators all have a large exposed warm surface area that transfers a gentle heat to the surrounding air (A.)

Mobile oil and gas heaters have elements that are small and intensely hot. They produce most of their output as radiant heat but also tend to create an extreme temperature gradient because they heat a small volume of air to a very high temperature. This encourages the cold and hot air to separate out into static layers with a thin layer of very hot air sticking close to the ceiling (B.) Cheap electric convector heaters that make use of small, high-temperature elements will produce much the same effect.
