A distribution valve controls a distribution ratio of a heat transfer medium between a hot water supply path including a heat exchanger for hot water supply and a beating circulation path through which the heat transfer medium is supplied to a heating terminal. A bypass flow rate control valve controls a bypass ratio which is a ratio of a flow rate of low temperature water introduced into a bypass pipe that bypasses the heat exchanger for hot water supply to a flow rate of low temperature water introduced into a water inlet pipe. The bypass ratio is regulated so that a hot water temperature detected by a temperature sensor reaches a hot water target temperature. During a simultaneous operation of hot water supply and heating, the distribution valve is controlled so that, when a bypass ratio is low, a distribution ratio is higher than when a bypass ratio is high.

A compact, on-demand system to produce high pressure (5,000 psig) and high temperature (450 C.) water or other liquids which maintains single-phase flow throughout the system utilizing low-cost, thick-wall tubing and thereby negate the requirement to design the unit as a boiler or adhere to coded pressure vessel design requirements. This design can also replace a conventional boiler for the generation of hot water as well as low and high pressure steam.

A liquid heating system includes an instantaneous heater (18) having an inlet (20) connected to a reservoir (62). The outlet (22) of the heater is connected to fixtures (72) which use the heated liquid, and is also connected through a return connection (30) to the reservoir. In an idle mode, a pump 40 draws liquid from the reservoir (62), so that the liquid circulates through the heater and back to the reservoir. A controller (52) actuates the heater to heat the liquid to a first setpoint temperature, so that the liquid in the reservoir stabilizes at the first setpoint temperature. In a supply mode, some or all of the heated liquid flows from the outlet to the fixtures (72). Cold liquid is admitted from a supply (60) to the reservoir, and cold liquid desirably also is supplied to the heater inlet along with liquid from the reservoir, so that the heater inlet receives a combination of these. The controller controls the proportion of cold liquid to liquid from the reservoir in the combination, so as to maintain the heater at a setpoint heating rate while also maintaining the temperature of liquid discharged from the heater outlet at or near a setpoint temperature.

A water supply and heating system that includes a flexible water tank, a flexible heating carpet and an electrical connection mechanism. The water tank includes a flexible outer layer and separable inflatable and collapsible water bag. The water bag is equipped with a water inlet and outlet hoses for receiving supplying water. The water bag is positioned inside the outer layer and is designed to remain collapsed when and to inflate when filled with water. The outer layer too is designed to inflate when the water bag is filled with the water and to deflate when the water is drained from the water bag. A dry space is defined between the outer layer and the water bag in which the heating carpet is positioned. The heating carpet includes flexible flat electrical heating strips that are connected to the electrical connection mechanism.
