Abstract: A liquid dosing system is disclosed and can include an inlet conduit and an outlet conduit. The inlet and outlet conduits can each be configured to fluidly communicate a heat exchanger of a water heater. The liquid dosing system can include one or more connector conduits configured to fluidly connect the inlet conduit and the outlet conduit to define a fluid circuit by at least the inlet conduit, the heat exchanger, the outlet conduit, and the one or more connector conduits. The liquid dosing system can include a pump configured to pump water through the fluid circuit, a reservoir configured to store an additive, and a dosing device configured to dispense the additive into the fluid circuit.

Abstract: A peristaltic pump system is disclosed and can include a rigid backing and a rotor assembly comprising a central hub. The central hub can rotate along a central axis extending in an axial direction. The central hub can include one or more ball bearings or one or more rollers that are configured to rotate about a respective roller axis that intersects a central axis of the central hub. Located between the rigid backing and the rotor assembly can be tubing or a flow channel that is defined by the rigid backing and an elastomeric sheet. As the central hub rotates, the one or more rollers or ball bearings are configured to push against the tubing or the flow channel in the axial direction and can move along the tubing or the flow channel to move fluid through the tubing or the flow channel.

Abstract: A water heating system having a tank and one or more heat sources for heating water is provided. The water heating system includes a water outlet for allowing egress of water from the tank and a dip tube for allowing ingress of water into the tank. The dip tube includes a first end for coupling with a water source and a second end disposed proximate a base of the tank for discharging water into the tank through an array of holes. Each of the holes is defined in a side wall of the dip tube and laterally discharges water with respect to a longitudinal axis of the second end of the dip tube.

Abstract: A liquid dosing system is disclosed and can include a cartridge comprising a reservoir configured to store an additive, an output vessel in fluid communication with the reservoir, and a cartridge outlet in fluid communication with the output vessel. The liquid dosing system can include a housing that includes a water passage configured to direct water though the liquid dosing system and a receiving portion configured to at least partially receive the cartridge when the cartridge is connected to the housing. The receiving portion can include a receiving port in fluid communication with the water passage, and the receiving port can be configured to receive at least some of the additive from the cartridge outlet when the cartridge is connected to the housing. The receiving portion can include a motor configured to engage in mechanical communication with the output vessel when the cartridge is connected to the housing.
