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.
Claims10
An installation for producing sanitary hot water, which comprises a boiler, a tank for storing hot water, a sanitary cold water intake conduit, a conduit for feeding the boiler with water to be heated, provided with a pump capable of ensuring circulation of the water to be heated towards the boiler when the pump is started and of preventing the circulation when the pump is stopped, a conduit for drawing sanitary hot water, and a conduit for the outflow of the heated water from the boiler, wherein said sanitary cold water intake conduit is connected via a first “T” connector to the boiler feeding conduit and to a recirculation conduit opening out into a low portion of the tank for storing hot water, while the boiler outlet conduit opens out approximately at a half-height of the hot water storage tank and the water drawing conduit opens out into an upper portion of the hot water storage tank, the sanitary cold water intake conduit being provided with a second “T” connector placed upstream from the first “T” connector,
- wherein:
- a portion of the sanitary cold water intake conduit connects the second and first “T” connectors, the portion being equipped with a small storage tank that is positioned between said first and second “T” connectors, a capacity of the small storage tank being less than that of the hot water storage tank;
- and
- the conduit for the outflow of the heated water out of the boiler is equipped with a three-way valve which is connected through a bypass conduit to the second “T” connector, the three-way valve selectively occupying either a primary position, in which the three-way valve has the boiler outlet communicate with the half-height portion of the hot water storage tank, to distribute the water issued from the boiler in the half-height portion of the hot water storage tank, or a secondary position, in which the three-way valve has the boiler outlet communicate with the bypass conduit to distribute the water issued from the boiler in the bypass conduit.
