Heat losses insulation

Two Evaculated Tube Collector

Diameter of pipe = 0.8mm

Tube length =195mm

Evacuated tube collectors are flat devises which consist of cylindrical absorbing surfaces or tubes with internal fins installed in an evacuated tube to reduce the convection losses. From: Thermal Solar Desalination, Insulating material

Active solar water heating

The main components on an active solar water heating system are

Solar collector to capture the suns energy and to transfer is to the coolant medium

A circulation system that moves the fluid between the solar collector and the storage tank

Storage tank

Back up heating system

Control system to regulate the system operatio
