A duct adapter system directs air flow relative to a hybrid water heater. The duct adapter system includes a collar adapted to surround a vent of a hybrid water shroud. The collar couples to standard duct pipe to extend ductwork to a heat pump portion of the hybrid water heater. A boost fan may be included in the system for boosting air flow to or from a remote location. The duct adapter system is adapted to deliver a warm air supply to the heat pump from the remote location, or deliver the cool discharge air from the heat pump water heater to a remote location.

A flue system is provided for a water heater having improved heat exchange efficiency. The flue system includes an upstream heat exchange portion providing a first pass for heat exchange with water in the water heater. The flue system further includes a downstream heat exchange portion providing a second pass for heat exchange with water in the water heater and a blower positioned between the upstream heat exchange portion and the downstream heat exchange portion. The blower is configured to urge combustion products from the upstream heat exchange portion to the downstream heat exchange portion.

A control system is shown for a series of two or more water heaters arranged in parallel. A cold water supply line delivers cold water from a cold water source to a cold water inlet at each of the respective two or more water heaters arranged in parallel. A low pressure restriction is present at each cold water inlet of the water heaters which presents a low pressure restriction to the flow of cold water at each cold water inlet. A by-pass valve is also present at the cold water inlets for by-passing cold water from the cold water supply line around each of the low pressure restrictions. A hot water discharge line receives and discharges hot water from each of the water heaters. A controller is used to control when each of the by-pass valves will be open or closed based upon demand with only the by-pass valves being open which are needed to meet demand placed upon the system.

Modifications convert an existing single-pass boiler to operate with a multi-pass combustion gas flow through the flue passages of the heat exchanger of the boiler. A diverting target wall is arranged partway along the length of the original combustion chamber, and an upper draft diverter is arranged in a flue collector chamber above the flue passages, to divert some or all of the combustion gas into a multi-pass flow pattern through several flue passages of the heat exchanger in series. The modifications may further include changing the nozzle oil delivery rate and cone angle, the oil supply pressure, the draft conditions, and others. Heat extraction from the hot combustion gas to the boiler water is increased, exhaust gas temperature is decreased, and overall efficiency is increased, to result in a fuel and cost savings.

The invention relates to a device for treatment of a liquid in a liquid flow system. The device comprises a housing with at least a liquid inlet and outlet for accompanying a liquid flow through the housing, at least one AC voltage source alternating at a switch frequency, at least a first and second electrode with electric connections to said at least one AC voltage source and control means for controlling the level of treatment of the liquid. The at least a first and second electrode and control means are at least partly located in said liquid flow of said housing. The invention also relates to a method of treating a liquid in a liquid flow system and use of the device and method in a through-flow electric liquid heating system or a liquid purification system.

Provided is a faucet device for an aircraft lavatory unit, wherein a second joint and a third joint are joined by inserting the third joint of a heater module into a second joint of a valve module, and screw members are used to fasten a first case and a second case. As a result, the valve module and the heater module are joined in series via the second joint and the third joint. A first connector of a controller module is joined to a third connector of the valve module and a second connector of the controller module is joined to a fourth connector of the heater module. The first joint of the valve module is joined to a water supply pipe. A fourth joint of the heater module and a faucet main body are joined via a pipe.

A sectional boiler is described as being made of cast iron or aluminum, in particular a condensing boiler, having essentially annular sections, a front section, a cover-shaped rear section and at least one center section being provided, which form a combustion chamber having an essentially surrounding heat exchanger made of a sectional block, whose annular water chambers are connected to one another via at least one hub and which has gap-like heating gas flues, having a return port and a feed port in the upper area and at least two armature rods for holding the sectional block together. The present system is based on the objective of optimizing a sectional boiler made of cast iron or aluminum particularly with respect to compactness and robustness. In the present system, as heating gas flues the heat exchanger respectively has annular gaps between two adjacent sections having a mutually adapted geometry, which respectively run from the combustion chamber approximately radially outward and open into an exhaust gas collection chamber on the outside of the sections, and the individual sections are respectively divided on the heating water side into at least two flow channels.

An outdoor wood-burning boiler is provided that includes a wood-burning enclosure, a wood support structure, and an air supply system configured for supplying air to wood that is supported by the wood support structure. The air supply system includes conduits for carrying a flow of air. At least one conduit can extend through a sidewall of the enclosure such that an end of the conduit is located outside of the enclosure. The end can include a re-closable closure. The re-closable closure can be configured to be opened from outside of the enclosure and provide access to the interior of the conduit so the conduit can be cleaned. The end and the re-closable closure can instead be located inside the enclosure and accessible through an access panel. An air supply conduit system is also provided that can be installed after-market or as original equipment.
