WHAT PROCEDURE OF FIELD TEST DO I USE TO SEE THE UNIT WORKING IN DOMESTIC HOT WATER SYSTEMS?
Potable water and its required purity presents our greatest challenge. ETROMACs units do not introduce any foreign contaminates which would alter the purity. The unit’s location, which is on the feedwater line at a point after the recirculated hot water premixes with the cold, then as it enters the hot water generator. Normal blowdown of this storage tank will reveal a residue of crystal deposits being discharged from the bottom drain. By observing this discharge and the increase in temperature, of the return hot water line, you will witness a shorter recovery time; also, a change of a more efficient heat exchange. Monitoring the T.D.S. in the raw water feed, as well as the circulating hot water at the furthest point in the system will show the rate of removal. Scheduled blowdown of the hot water storage tank should not be neglected. Water flow rates will increase at all points in the system. Sectionalizing a piece of the water line at a remote location will provide a method to visibly
