Heat and hot water supply system arranged in upper storey of building - is operated with gas, heating oil, current or other energy source and has heat exchanger of surface water connected with central heating heat exchanger for usable water

摘要

The central heating heat exchanger is connected to the twin tubular casing power duct, which is connected with the branch lines, in which lie the individual central heating pipes. The supply and return pipe lines are led through the twin tubular casing power duct without insulation. A rotary pump is arranged in the lowest section of the twin tubular casing, which returns the circulated water across the heat exchanger for warm waste water, and otherwise to the hot water heat exchanger. ADVANTAGE - Makes economic use of heat in system to give high efficiency and CO2 discharge is substantially reduced.
