Abstract
For a shower for a household, dormitory or the like, which typically has a limited volume of boiler-heated water available for use, the cold water input to the shower is passed in heat exchange with the discharging tepid water to thereby convert same to a lukewarm water source, the temperature change being typically a 15 to 25 degree rise, whereby significantly less boiler-heated water is required for preparing a suitable tepid water mixture confortable for showering. The aforesaid significantly prolongs the showering service use of the system and, since less boiler-heated water is consumed, correspondingly lessens the fuel consumption of the boiler.
Claims10
An improved method for minimizing the amount of boiler-heated water consumed in the premixing of hot and cold water inputs to a shower, said method comprising the steps of directing the premixed water exiting from said shower along an advantageous flow path for heat exchange, flowing the cold water input to said shower in heat exchange relation with said exiting water to produce a resulting lukewarm water source incident to the use thereof for said shower, and diminishing the boiler-heated hot water input to said shower of an extent permitted by use of said lukewarm water source, whereby whatever the storage volume limitation of said boiler-heated hot water it is extended for a greater duration of use for showering purposes because of said diminishment.
The combination with a shower of the type having cold and boiler-heated warm water inputs thereto for premixing said water preparatory to use in showering and an exit drain for said discharging premixed water, an improvement for minimizing the amount of boiler-heated water consumed in said premixing comprising heat exchange means operatively disposed in said cold water input to said shower in heat exchange relation to said exit drain of said discharging premixed water, whereby said cold water is rendered lukewarm to contribute to lessening the amount of boiler-heated warm water for showering purposes.
