Why Copper?
 
Copper is a tried and tested material - used since Roman times. It has excellent anti-bacterial qualities. On test, after 7 days of immersion in water, 80% of stainless steel and plastics were coated in a biofilm, while copper showed little or no biofilm. Biofilms are harbingers of E.coli 0157 and other microbiological bugs and pose a significant threat to human health.
 
In a recent article Copper is called the Vital Element of Life - “Copper could be more important to the health of an unborn baby than folic acid, giving up smoking or abstaining from alcohol, say scientists. Trace amounts of copper are present in all body tissues. It is needed to process oxygen, generate energy in cells, allow the nervous system to transmit signals, grow blood vessels and develop skin, tendons and hair.”
 
Copper has been used for good reason over the years and continues to be the best and safest material for hot water storage.
