As much as 80 to 90 percent of heat loss (or gain) through ceilings and 60 percent of heat loss (or gain) through walls can be prevented by properly insulating these areas. The inefficiency of ordinary building materials in resisting the passage of heat brought about the need for the development of materials specifically designed for insulation. A good insulating material should be lightweight, contain numerous air pockets, and exhibit a high degree of resistance to heat transmission. The material should also be specifically treated to resist fire and the attacks 27 28 Chapter 3 of rodents and insects.

Internal latent heat 2. External latent heat These are explained in detail in the next section under Steam. 1 LB OF WATER 1 LB OF SUBSTANCE Temperature Rise 1؇F 1 Btu required A Temperature Rise 1؇F B SPECIFIC HEAT ϭ Figure 2-7 B (Btu) A (Btu) The principle of specific heat. 16 Chapter 2 Heat-Conveying Mediums As mentioned in Chapter 1, several methods are used to classify heating systems. One method is based on the medium that conveys the heat from its source to the point being heated. When the majority of heating systems in use today are examined closely, it can be seen that there are only four basic heat-conveying mediums involved: 1.

DROP OF WATER FILM OF STEAM RED-HOT PLATE Drop of water on a hot plate illustrating the spheroidal state. Figure 2-6 Heating Fundamentals 15 Specific, Sensible, and Latent Heat The specific heat of a substance is the ratio of the quantity of heat required to raise its temperature one degree Fahrenheit to the amount required to raise the temperature of the same weight of water one degree Fahrenheit (Figure 2-7). This may be expressed in the following formula: Specific heat ϭ Btu to raise temp. of substance 1ЊF Btu to raise temp.
