The GEYSER BLANKET is a fast, simple, and cost effective method of saving up to 27% of your electricity bill in WINTER and SUMMER.
The GEYSER BLANKET consists of a polyester fiber insulation material, laminated with a reflective foil facing. The essence of fitting

a geyser with the Geyser Blanket is to minimize the thermal energy (heat) loss, thereby saving energy. Eskom DSM supports the
installation of Geyser Blankets.

In 2007 a 122,500 GEYSER BLANKETS fitted for ESKOM with a saving of 5.82 MEGAWATT (27% Saving)
The GEYSER BLANKET complies with all test requirements as per the CSIR Fire Tests, as well as the Moisture Absorption and Fungal
Attack Tests conducted by the SABS. The PIPE INSULATION works hand in hand with the GEYSER BLANKET. The Pipe Insulation is
simply wrapped around the hot water pipes so as to keep them insulated and minimise the loss of heat and energy.
