    Ottimo prodotto. Ha risolto definitivamente il problema delle perdite sull’impianto di riscaldamento che avevo sia su giunzioni ed anche nello scambiatore della caldaia. A distanza di un anno dal suo inserimento non ho avuto più necessità di ripristinare la pressione che continuamente andava a diminuire. E stato sufficiente un flacone per un impianto in appartamento da 140mq. Il procedimento adottato nel mio caso è stato molto semplice, per l’inserimento ho scelto un termosifone dei piani alti che tipicamente raccoglie aria nel caso non ne avesse vi suggerisco di chiudere uno sia con la valv9la superiore che inferiore, quindi allenando il raccordo inferiore far uscire un po d’acqua con la valvola di scarico aria aperta. A questo punto toglieno la valvolina di scarico aria ho versat9 con un tubicino tutto il contenuto della confezione all’interno del termosifone. Quindi rimontato la valvola ho riapert9 il termosifone e ripristinato la pressione della caldaia. Dopo di che ho acceso in modo continuativo i termosifoni per un,intera giornata alzando la temperatura del termostato in modo che non si fermassero mai. E molti importante verificare che tutti i termosifoni si scaldino e con non vi sia aria nell’impianto. Facendo in questo modo il liquido si distri unisce in tutt9 l’impianto raggiungendo tutt ele perdite di acqua presenti. E molto importante tenere in circolo l’acqua per evitare che si possano verificare Accumoli di prodotto e solidifcazioni in solo anch’io pu ti dell’impianto. Ovviamente preferibile farlo d’inverno in modo da non avere problemi a far stare accesi i termosifoni. Quest’anno inserirò una nuova dosa in modo da rinforzare eventuali punti deboli anche se come dicevo con un solo flacone già ha ottenuto un risultato inaspettato.Spero che questa mia esperienza vi possa essere di aiuto.

    Dieses Zeug ist wirklich unglaublich. Unser Heizkessel verliert Wasser. Nach hinzufügen dieser Flüssigkeit in den Heizkreislauf wurde es zunächst vollkommen dicht, dann allerdings vermutlich durch weiteren Rostfraß wieder undicht. So habe ich die Behandlung noch einmal mit Erfolg wiederholt. Für das kommende Jahr werden wir uns allerdings wohl eine neue Heizung besorgen müssen.

    Mijn vloerverwarming had een lekkage, wist niet of dit ook geschikt was voor vloerverwarmingsslangen maar daar lijkt het wel op. Na dit middel te hebben toegevoegd hebben wij geen drukverlies meer.He wel voor de zekerheid de slangen goed doorgespoeld met schoon water voordat ik het erin deed.

    En fait je l’ai utilisé pour boucher de l’intérieur une fissure dans un vieux siphon de baignoire en laiton, qui est difficilement accessible. Les odeurs d’égout ont pratiquement disparues. C’est trop récent pour donner un avis vraiment fiable à 100%, et ce produit n’est pas fait pour cela. ceci dit, à part le prix un peu cher, j’en suis satisfait.
