摘要： The invention relates to a water heater comprised of a cylindrical tank 18 which has a central flue 20 that is mounted with the cylinder axis 40 vertical. The water heater further includes a gas burner 22 provided the base of the tank 18, which burns a gaseous fuel so as to discharge heated gases up through the central flue 20 from the base to the top of the tank 18. A housing 12 surrounds the exterior of the tank and is spaced away from the domed top 34 and side walls of the tank 18, to thereby define a generally annular cylindrical space 36 between the radially outer surface of the tank 18 and the radially inner surface of the housing 12. The annular space 36 is in gas flow communication with the upper end of the flue 20 and is provided with a discharge outlet 48 located at or adjacent the lower most end of the tank 18. In use heated gases pass up the central flue 20, over the top 34 of the tank 18, and down the annular space 36 to thereby heat both the radially inner and the radially outer surfaces of the tank 18 prior to exhausting from the heater.

摘要： A method and apparatus for controlling the normal operation of a hydronic heating system, (including AC powered, gas-burning hot water boiler, multi-zone systems) using a DC power source, such as battery power, as the primary continuous source of electricity. Control functions minimize the consumption of electric power during normal operation, and eliminate standby electric consumption in order to extend the life of the batteries and maximize the run-time of the heating system. A DC to DC converter supplies low voltage DC power to the zone thermostats, and also supplies the proper voltage through zone relays to operate DC zone pumps. By allowing the use of DC power for the thermostats and zone pumps, the system eliminates the need for transformers, zone valves, and AC circulators, resulting in a large savings in electrical consumption and the elimination of the standby electric demand (“phantom load”) common in conventional hydronic heating systems. A DC to AC inverter is dedicated to supply AC power for a hydronic (hot water) boiler. The inverter is switched on by relays only when needed, thereby eliminating the “phantom electric load” consumed by most boilers when standing by. A time delay relay circuit allows the boiler to go through its proper shutdown sequence before power is removed. This control system does not require any internal modification to the other heating system components.
