The invention relates to a thermal flywheel with nano fluid meant for the heating of indoor spaces during the winter-to-spring and autumn-to-winter transition periods, when the outdoor temperatures do not satisfy the criterion of duration required for starting the central heating plants, i.e. three consecutive days of temperatures lower than 10°C. According to the invention, the thermal flywheel consists of radiant panels made with some capillary tubes (1) connected in closed loop with a heat-accumulator storage device (2) by means of a circulation pump (3) and some connection pipes (5) provided with some electrically-actuated three-way valves (4), allowing the circuits to be selected in day-time regime, by means of an external panel (E) for collecting solar energy and the storage device (2) to be charged in night-time regime, in order to be discharged through an internal panel (I), for heating the space concerned, the system efficiency being thereby increased when phase-change materials are contained in the plastering. Invenţia se referă la un volant termic cu nanofluid, destinat încălzirii spaţiilor interioare în perioadele de tranziţie iarnă-primăvară, respectiv toamnă-vară, când temperaturile exterioare nu satisfac criteriul de durată pentru pornirea instalaţiilor centralizate de încălzire, trei zile consecutive cu temperatura inferioară valorii de 10°C. Volant termic, conform invenţiei, este constituit din panouri radiante realizate cu nişte tuburi (1) capilare conectate în circuitul închis cu un stocator (2) acumulator termic prin intermediul unei pompe (3) de circulaţie şi a unor conducte (5) de legătură prevăzute cu nişte robinete (4) cu trei căi acţionate electric, care permit selectarea circuitelor în regim diurn printr-un panou (E) exterior pentru captarea energiei solare şi încărcarea stocatorului (2) în regim nocturn pentru descărcare printr-un panou (I) interior, pentru încălzirea spaţiului deservit, iar astfel eficienţa sistemului creşte în situaţia în care în tencuială sunt mixate materiale cu schimbare de fază.
