Potable water heater and method of using same

Water heating system for a vehicle or boat comprising a heater fluid loop with heater fluid therein, an engine circuit with engine fluid therein, a space heating loop used for heating a living environment and being operable to allow said heater fluid to circulate therein, a first heat source to heat said engine fluid, a second heat source to heat said heater fluid, a valve to route said heater fluid through said space heating loop or to bypass said space heating loop, said valve being operably connected to a thermostat for measuring the temperature of said living environment to be heated and for instructing said valve to route said heater fluid through said space heating loop or to bypass said space heating loop.

A heating system for heating an environment within a boat or vehicle, said heating system comprising a first heater, a first fluid circulating through said first heater and a potable water heat exchanger, a second fluid circulating through said potable water heat exchanger and being heated by said first fluid in said potable water heat exchanger, said second fluid being potable water.

A heating system for heating an environment within a boat or vehicle, said heating system comprising a fuel powered heater, a heater fluid line carrying fluid circulating through said fuel powered heater, a pump to circulate heater fluid through said heater fluid line, said heater fluid in said heater fluid line being heated by said fuel powered heater, said heater fluid line extending though at least one space heater in a living environment, said heater fluid in said space heater providing heat to said living environment and a temperature sensor to sense the temperature of said living environment and to control the ingress of said heater fluid into said space heater or to bypass said space heater according to said temperature sensed by said temperature sensor and a potable water heat exchanger having an aquastat and a potable water line carrying potable water associated therewith, said heater fluid line extending through said potable water heat exchanger and exchanging heat with said potable water in said potable water line, said aquastat controlling the operation of said fuel powered heater.

Apparatus for displaying system status in a text and numerical form for a water heating system used in a boat or vehicle comprising a micro-controller for converting hexadecimal data or serial communications received from a control board into a text and/or numerical user friendly format display, said apparatus displaying the status of components of said water heating system and for displaying faults associated with said components of said water heating system.

Method for displaying in a user friendly format text and numerical information relating to a water heating system used in association with a vehicle or boat comprising visually displaying said text and numerical information in said user friendly format on a display, intermittently interrogating a control board connected to components of said water heating system, determining whether a fault is present which fault is associated with individual ones of said components, converting said fault information to said text and numerical information in said user friendly format and displaying said text and numerical information in said user friendly format on said display.

Method for displaying user friendly text and numeral information relating to a water heating system on a vehicle or boat comprising positioning a display device for visually displaying said user friendly text and numerical information for viewing by a user in a convenient location for said user, continuously interrogating a control board connected to components of said water heating system, determining whether a fault is present which fault is associated with individual ones of said components, converting said fault information to said user friendly text and numerical information and displaying said user friendly text and numerical information on said display device.

Apparatus for displaying system status in a text and numerical form for a water heating system used in a boat or vehicle comprising a display device for for displaying system status in a text and numerical form for said water heating system comprising a micro-controller for converting hexadecimal data or serial communications received from a control board into a text and/or numerical user friendly format display, said apparatus displaying the status of components of said water heating system and for displaying faults associated with said components of said water heating system.
