1. A fluid heating system for recreational vehicles, boats or off-grid housing, comprising:
a closed piping loop with at least two heat input sources and at least one heat dispensing unit, all connected in-line with said piping loop;
a heat transfer fluid inside said piping loop;
an expansion tank connected to said piping loop;
a system circulating pump in-line with said loop for circulating said heat transfer fluid from said expansion tank around said piping loop;
a first heat input source comprising an electric heater located inside said expansion tank, said electric heater connectable to an AC power source;
a second heat input source comprising a gas furnace which is connectable to a gas source, said gas furnace connected in-line with said piping loop;
a furnace controller operatively connected to said gas furnace;
a first heat dispensing unit comprising a radiator fan connected in-line with said piping loop;
a microprocessor system controller operatively connected to said at least two heat input sources and to said at least one heat dispensing unit, wherein said microprocessor system controller has a wireless communication transceiver in communication with a user's smart phone, a wireless communication circuit, a maintenance data interface connected to said furnace controller by a CANBUS circuit, a furnace restart circuit connected to said furnace controller by a CANBUS circuit, and an air pressure circuit operatively connected to said system controller for adjustment of said gas furnace;
a tactile control unit operationally connected to said microprocessor system controller for the input of fluid heating system operational parameters to said microprocessor system controller;
a local temperature sensor connected to said tactile control unit;
at least one DC power source connected to at least said system controller, said tactile control unit, said system circulating pump, said radiator fan, said gas furnace, said air pressure circuit, and said furnace controller;
wherein said microprocessor system controller operates said circulating pump to circulate said heat transfer fluid around said piping loop and through said at least two heat sources and through said at least one heat dispensing unit; and
wherein said microprocessor system controller provides operating signals to said at least two heat sources and said at least one heat dispensing unit; and
wherein said user's smart phone is wirelessly connectable to said furnace restart circuit by said wireless communication transceiver and wireless communication circuit, for the purpose of restarting said gas furnace after a furnace shutdown has occurred.
