Solar Water Heater
am interrested in 100, 200 and 300l solutions. High pressure, low pressure and split systems. Operating with or without circulation pump. Circulation pumps preferiable solar driven. Please include in your quotation, what it is included (like valves, c-pumps, elec. elements, controller units, spare parts, tanks e.t.c.). I am also very interrested in balcony units (100 -150 l). South Africa received about 9500MJ per annum per m2 solar energy and 99 percent of all buildings are still without any solar- system. Besides we have a massive power-shortage, the market is massive.
It will be very helpfull if you can attach some installation instructions for your units to connect to existing electric warm water cylinders. The normal water pressure inS.A. is between 3 and 4 bar.
Please understand that I can not respond further without any price quotation for at least some products from your side. For comparing price-quality-functionality with other products please quote as detailled as possible. First order of 3 container (product mix) is planned for April/ May 2008. We will deliver and install nation wide.
