Finned Oil”
Whether it is a source of heat pump air or soil, hot water bottles copper have been widely recognized as the best and most cost-effective for use in conjunction with the system.
Heat pumps work by extracting heat from an external source through a liquid boil at low temperatures. When the liquid boils, which are vaporized and this vapor is then compressed into a small space.
By compressing the steam, its temperature increases and is at this moment that the hot steam is passed through a heat exchanger. Because higher copper transfer properties heat, which makes the material more efficient to do this and using a copper coil with fins, the surface can be much more to promote the process transfer even more.
Copper has a conductivity 401W/mK heat, which, compared to stainless steel with a score of 14W/mK it easy to see why copper is the material of choice
A major advantage of using copper cylinders with heat pump systems, is that it has natural antibacterial properties.
Because of how heat pumps work, usually water heat to a temperature of 45-55 degrees, which can provide fertile ground for bacteria such as E. Coli, and Legionella.
Copper for the eradication of MRSA, E-coli and avian flu in less than 5 hours (1). The testing took 34 days for E-coli 0157 to die in stainless steel, brass 4 days and only 4 hours in copper (2) 99% of the bacterial population is placed in a copper plumbing system disappears in less than five hours. Copper is recommended fight against legionella.
Add in the fact that copper has a higher degree of versatility for the manufacture of the cylinder and the fact that copper has a exceptional resistance to corrosion to ensure that the hot water tank is made in the years to come.
And if that was not enough, more than 90% of all copper used again and again, as the last option, as well as the environment and economically.
McDonald Engineers are a specialist hot water cylinder manufacturer, with a range of products including heat pump cylinders, thermal stores, domestic vented and unvented cylinders as well as Commercial and Industrial Calorifiers.
