<p>The invention relates to a heating installation destined to heating dwellings and for producing domestic hot water. The heating installation consists of a basic module (A) provided with an inner wall (7) which, together with the outer shell (8), forms an annular compartment (d) connected to a cylindrical serpentine (11) wherein a first radiating body (13) filled with sand is provided, the serpentine (11), in its turn being connected by means of an external pipe (16) to a second cylindrical serpentine (15) , located in an intermediary module (B), which rests in an upper recess (a) of the basic module (A) and which is endowed in the central space with a second cylindrical radiating body (19) filled with sand, positioned axially through which a central orifice (k) passes for passing the hot air, and which is surrounded by other prism-shaped radiating bodies (21) filled with sand, located coaxially between the cylindrically-shaped radiant body (19) filled with sand and the serpentine (15), delimited by a wall (m) and a coaxial shell (n), between the wall (m) and the coaxial shell (n) there being formed a ring-shaped enclosure wherethrough the water circulates, this being connected to the lower and upper ends of the second serpentine (15), through some equally spaced radial pipes (20), to a ring (h) of the second serpentine (15) and to a ring (i) of the first serpentine (11), a module ( C ) meant for the hot domestic water circuit being located axially on the intermediary module (B), and the water as thermal medium circulates through the annular compartment (d), through the serpentines (11 and 15) and through the ring-shaped enclosure (o).</p> |
