Hi All, I have a on-demand gas hot water service and have found that when its quite cold in the mornings or late at night, i cant get any hot water. If i wait until it warms up a little, hot water flows through fine.
I have looked at the unit, and it is successfully sparking when hot water is requested, but the flame never lights - my guess (and it is a wild guess) is that the thin gas pipe for lighting the flame has got blocked by some moisture which has frozen when its cold and clears when it warms up a little.
Anyhoo - anyone got any suggestions on what i can do to allieviate this issue? As you can imagine, not having a shower before work isnt too nice.
Thanks for any help.
