IDEAL ISAR HE30

[davidhwdn]

My boiler has just been serviced and it's working fine but this morning i heard a noise like the flame blowing in the wind and a letter t was on the electronic display,any ideas please.The letter disappeared after a few seconds and it's working fine but i looked at the user manual and could not find anything to do with t on the fault codes.

A "t" in display shows that boiler is going through a preheat cycle. This is to keep the domestic water heat exchanger hot. It does this every hour or so to have hot water on demand. Not a fault condition.

Thanks for that,nowt to worry about then.

 

[crad2]

Nothing to worry about. It will tend to do it more frequently in this cold spell too.

crad, i have the isar 24 and, according to the book it also has this preheat, but never in 4 yrs have i heard or seen the "t" in action.

boiler works a good en, but just wondered, wouldn't come with an auto bypass would it?. thanks.
