Im wondering if anyone has come across this before. Customer reports they are only getting hot water on some days from there economy seven set up. The Eco seven is working as expected as storage heaters getting warm. Does this sound like a Hortzman timer issue or element issue possibly? As I can't reproduce the issue and its intermittent, is a bit of a strange one.

what about a problem with the thermo stat.

if there is a timer for the water its not going through the same timeswitch as the heaters anyway (unless its dual fead ?). have you looked at it or just spoken to customer. is the time on the timeclock correct? it sounds like a dodgy timer to me, i'd check the connections and get them to try it manually for a couple of days. i changed a horstman a while back and thought i might be able to just change the front. unfortunately they have changed something inside with the push on connections and it wouldn't go back properly.

Hi Gary,

That a good point about the timer clock being out, the heaters are eco 7 separate board but the hot water is off a Hortzman timer, going armed with a new one and swapping that in first instance (if timer isn't off)

Check the clock for "day omission" - if it's been messed about with, anything could be happening - it won't automatically synch with the DNO timeswitch anyway.

from there, it could be a faulty clock or faulty element stat (or finally a duff over temp cut out)
