TURBULENT HEATER Russian patent published in 2012 - IPC F24J3/00 

FIELD: instrument making.

SUBSTANCE: target goal is achieved by the fact that an inner surface of a body has a coating from metals of aluminium, copper, silver, nickel, chrome or zinc with the reflecting capacity of thermal (infrared) radiation from 90 to 99 %, and having coating surface roughness from 0.2 mcm to 3.2 mcm, and an outer surface of the body is coated with a heat insulation paint. As a result of lower heat losses to environment, intensity of liquid heating is increased by 10-15 %.

EFFECT: lower heat losses to environment and higher efficiency of liquid heating.
