When the tube is exposed to the sun, the solar selective coating absorbs the solar energy and transfers it to a heat pipe that is located inside the inner tube. The heat pipe contains a heat transfer fluid (typically water or ethylene glycol) that transfers the heat to the systems manifold.Heat Pipes, Solar Heat Pipe - Apricus Solar Water HeaterThe heat pipes used in AP solar collectors have a boiling point of only around 30 o C (86 o F), so when the heat pipe is heated above this temperature the water begins to vaporize (turn to steam). This vapour rapidly rises to the top of the heat pipe and carries with it large amounts of heat.How To Heat Your Home With Solar Heating - Off The Grid NewsTo add active solar heating to such a system requires a solar collector, which will heat water from the sun, an additional heating coil to be placed inside the air handling unit and a small circulating pump to move the water between the two.
