Problems solved by technology

[0031] This phenomenon, which is repeated every time the water is pumped, can quickly cause fouling to some extent and render the exchanger equipped with the water heater inoperable
[0032] Another disadvantage encountered in this known device is that the energy consumed during the cooling of the stagnant water in the ducts (including in the exchanger) until the next pumping of water is decisively lost, which affects the overall energy output of the device

Embodiment Construction

[0058] refer to figure 2, showing a clean hot water generator connected on the upstream side to an inlet EFS for clean cold water, which may be present in a simple drinking water tap, connected on the downstream side To a clean hot water outlet ECS that supplies water to one or more points of use (eg sink, washbasin, shower, bathtub).

[0059] The device comprises a water heater 1 provided with a burner 60 charged with a combustible mixture, for example a gas / air mixture or an oil / air mixture, by means of a fan 6 with adjustable flow.

[0060] The function of this device is to heat the clean cold water by means of the water heater and keep the clean hot water stored in the storage tank 2 at a given temperature, usually about 65°C, from which the clean hot water can be extracted as required to Provides water to one or more points of use.

[0061] Typically, the tank is generally cylindrical in shape, with a vertical axis, with hemispherical ends, and is supported on the grou...

Abstract

The equipment of the invention includes a boiler, a hot water storage tank, a duct for supplying domestic cold water, and a duct for tapping domestic hot water, wherein said equipment is characterized in that the duct for supplying cold water comprises a T-shaped connector connected by a duct provided with a storage vessel to a re-circulation duct connecting the tank to the inlet duct, provided with a pump, of the boiler, and in that the outlet duct of the boiler is provided with a three-way valve connected by a by pass duct to said T-shaped connector, wherein said valve can selectively assume a position in which it ensures communication between the boiler outlet and the central portion of the tank, or a position in which it ensures communication between the boiler outlet and said bypass duct.

Description

technical field [0001] The present invention relates to a device for producing clean hot water. Background technique [0002] Traditionally, individual and communal dwellings have been equipped with devices for producing clean hot water consisting of a water heater and two exchangers, one of which is called a primary exchanger and the other a secondary exchanger. [0003] A water heater operating, for example, with gas or oil is used to heat the first liquid. [0004] Advantageously, in the case of a so-called mixing device, it can be the water that circulates in the radiators of the central heating system. [0005] For this purpose, the water heater is equipped with a primary exchanger which has the function of transferring a part of the heat generated due to the combustion of the gas through the burners of the water heater equipment. [0006] This water heater is for example of the condensing type and comprises a helical tubular coil, for example made of steel, which sur...
