hi everyone
we have a site where i work that has old calorfiers and is a pumped system on 1 insh metal pipe work and despite numerous drain downs and the like we get the following.
heat flows through great for about 20 minutes then goes cold quite quickly
rads on the other side of the circuit work fine
we have tried many methods including back filling form a hose and a pump from the calorifer to no avail ??????????
has been flushed though as well both the calofier both in feed and outlet
any ideas appreicated
