The Eco Max geyser has been designed to meet the new B-rated energy requirement, and has dual electric and solar applications. The Eco Max incorporates an integrated isolator switch, which simplifies on roof installations whilst meeting current SANS requirements. Eco Max geysers are manufactured in 2mm Mild Steel, are Enamel lined and are available in 100L, 150L and 200L tank sizes. By maintaining a PU foam thickness of 58mm all around the Eco Max geyser, any heat generated is retained for a longer period of time, reducing the electrical cost to the user. The PU foam used in our production process is a specially designed Eco Friendly formula which reduces the impact on the environment. The outer casements are available in galvanised steel or chromodec (white or grey); and has been designed with integrated carry handles which allow vertical free standing and eases handling and storage.

GAP has a range of solar solutions that is able to meet the growing demand for energy saving systems, ranging from domestic to large scale industrial systems, including custom designed residential housing projects for developers. GAP solar systems are available in Direct and Indirect configurations, and installed either as a pumped or thermosiphon system.

Thermosiphon systems

Thermosiphon systems rely on a natural process where the heat generated in the Solar Collector is transferred to the Geyser above the solar collector through a thermal process. No mechanical process or electrical system is required. Thermosiphon systems are highly efficient and require little to no maintenance.

Pumped or Retrofit

Pumped systems use a Solar Collector positioned on the roof to absorb thermal heat and rely on an electrical pump to transfer the heated fluid into the geyser positioned out of sight inside the roof. Pumped systems are aesthetically pleasing and in some cases the existing geyser already installed in the house can be converted to solar.

Direct and Indirect

Direct systems use the water in the geyser as the heating fluid, as a result they are very efficient but can be susceptible to freeze and are not recommended for areas with bad water quality. Indirect systems rely on Glycol as the heating fluid in the system, for this type of system a special geyser is required that is able to transfer the heat to the water in the tank. Indirect systems are freeze resistant and are able to withstand adverse water conditions.
