Heat transfer can be described in the network above, so that the overall heat transfer is calculated by dividing overall temperature difference by the amount of thermal resistance: Overall heat flow as a result of the combined conduction and convection can be expressed by thorough heat transfer coefficient (U), formulated in relationship:

It is used in calculating the heat transfer, typically by convection or phase transition between a fluid and a solid. The heat transfer coefficient has SI units in watts per squared meter kelvin: W/(m 2 K). Heat transfer coefficient is the inverse of thermal insulance. This is used for building materials (R-value) and for clothing insulation.

The overall heat transfer coefficient is the reciprocal of the overall resistance to heat transfer, which is the sum of the individual resistances. The overall heat transfer coefficient may also take into account the degree of fouling in the heat transfer process.

boilers may also be referred to as 'fire tube' or 'smoke tube' boilers tubes, which in turn transfer heat to the surrounding boiler water. . This factor is calculated by dividing the amount of steam produced per second by the area of the water.

Q = h A (Ts - T∞) or Q = h A ΔT. Where: Q = forced convection heat transfer rate (W) h = heat transfer coefficient (W/m 2 K) A = exposed area of metal. Ts = temperature of surface heating transfer element (K) T∞ = free stream temperature (K) Forced convection is different with natural convection.
