Installing insulation on your Hot water tank is Energy Efficiant and saves electricity and money by reducing the Heat losses of the Geyser or Heating storage cylinder. We did a project for ESKOM the South African power utility in 2007 and we manufactured and installed a 122,500 Geyser Blankets saving 5.28 Mega Watts. A geyser Blanket saves about 27% electricity based on a study done by the Cape University of Technology. This is a training DVD series on installation & product training. Installing Roof insulation stops Thermal Losses in winter and radiant thermal heat penetracing through your attic or ceiling in summer. The product has a aluminium foil layer and is a bulk as well as reflective insulation.
