摘要： An integral water circulation apparatus supplies instant hot water at hot water faucets remotely located from the building water heater through a convective circulation flow of hot water from the water heater It is therefore simpler in design, less expensive to install, and more reliable than the more complex prior art systems. It has the further advantages of not mixing heated water with cold water being supplied to cold water faucets throughout the building and of preventing cold water from flowing up the return line to the hot water faucet

摘要： A water circulation apparatus to provide instant hot water to faucets remote from the heater in residential and small commercial buildings when water is periodically used in the building. The apparatus comprises a body containing an aspirator and a check valve, and provisions for installation in the water supply line to the heater and cold water faucets. It uses a small water return line from a tee installed in the hot water pipe near the remote faucet, to a connector on the water circulation unit, thereby establishing a circulation loop from the water heater, through the hot water pipe, the tee and return line, and through the water circulation unit back to the heater. The aspirator is a tapered bore in the body with a concentric nozzle positioned in the large end, and a low pressure tap located in the vicinity of the nozzle outlet. The check valve uses a neutrally buoyant poppet to minimize friction.The unit is responsive to the user and is self regulating in that it causes water to flow in the circulation loop only when water is being used in the building. Water is conserved since there is no need to run water to waste awaiting hot water from the heater to reach the remote faucet. When the building is unoccupied, the unit is dormant, thus conserving heat that would be lost if the pipes were kept hot at all times. The unit needs no gas or electrical power, and operates with only one moving part.

摘要： A dual mode water circulation apparatus to provide instantaneous hot water to faucets remote from the heater in residential or small commercial building water systems. The apparatus comprises a cold water heat exchanger, a high sensitivity check valve, and an aspirator incorporated into a single unit.The heat exchanger is a chamber installed in the cold water supply line, containing a cooling tube exposed to the water. The check valve has a neutral buoyancy poppet and closes against an angular seat. The aspirator has a reduced cross section nozzle inside a tapered chamber connected to the water supply pipe, with a low pressure tap in the chamber bore.The apparatus is installed at an angle to the horizontal. The cooling tube is connected to a water return line from a tee in the hot water pipe at the remote faucet. The water circulation loop is from the remote hot water faucet to the heat exchanger portion of the apparatus, to the check valve, then to the aspirator and into the cold water supply to the heater.A continuous, low rate convective flow is induced in the loop by the heat exchanger, and a higher rate aspirated flow is present whenever water is used in the building. The apparatus is self regulating in response to user needs.
