Abstract
In order to solve the numerous problems with existing steam, vacuum, and hot water heating systems, presented are novel systems and methods of vapor vacuum heating having several improvements over the prior art, including: condensate return which can operate without steam traps; naturally-induced vacuum; improved vacuum pump operation for sustaining vacuum in such systems; liquid lift apparatus for use with such systems; and other improvements. All innovations presented herein make vapor vacuum heating more efficient and economical for industrial, commercial, and home applications. A field test conducted with these innovations show results of about 26-50% reduced energy usage, implying significant energy savings from the use of the present invention over current heating systems.
