    Abstract: The present invention relates to a user activated hot water heater and control system for processing hot water to hot water output locations, e.g. faucet, shower, or the like, such that temperature fluctuations and delays in hot water delivery are reduced. The present invention provides energy savings resulting from smart activation of internal and/or external recirculation systems. Additionally, trickle flow is detected and responded to based on temperature responses at various points in the main flow line of the present configuration. Simultaneous internal and external recirculations are made possible with advantageous placement of a pump within internal and external recirculation loops and a solenoid valve within the internal recirculation loop. The present system further comprises a means for adjusting the pump action in response to a thermostatic valve, temperature sensors advantageously placed in the main flow line to reduce dead heading.

    Abstract: An on demand tankless water heater system that is capable of quickly delivering water within a desired temperature range. The tankless water heater provides a hybrid heating method that contains a primary heating system and a secondary heating system disposed in a buffer tank that cooperate to facilitate control of output water temperature during water usage. A pressure differential switch detects low flow demand and allows the secondary heating system to provide immediate heating to the water. This secondary heating system provides a faster temperature response and fine tuning of output water temperature.

    Abstract: A novel water heat exchanger with a helix coil incorporated into a stainless steel elongated variable diameter cylindrical housing. A buffer tank is incorporated within the lumen of the helix coil. In one embodiment, the heat exchanger utilizes a radial direct-firing burner and a blower-driven hot flue gas to heat water for domestic and commercial use. In one embodiment, at least a rope seal is disposed between adjacent coil loops of a portion of the helix coil for enhancing heat transfer to the helix coil. In one embodiment, solar and electric heating systems are combined with the helix coil heat exchanger and disposed within the buffer tank to provide supplemental heating. In another embodiment, the heat exchanger further comprises a Stirling engine comprised of a free piston having hot and cold ends that is disposed within the cavity taken up the buffer tank, wherein the hot end receives heat from the burner and the cold end is cooled by the incoming cold water line to form an electric power generator.
