Saunier Duval F30 E

[taffe]

Hi there wonder if you had any ideas
My daughters boiler Saunier Duval F30 E
Seems to be playing up.
When you run the hot water you have to slow
The flow right down to get the water hot
Especially for the bath any ideas

That can be all sort of problem! Some gas related.

Sometimes daughters have Great Expectations which mere boilers dont live up to!

However, to put it in perspective its necessary to slow the flow until you can only JUST keep your hand in the water ( about 44°C ) and then measure the flow rate in litres/min.

Probably a matter of incoming water very cold and flow too high, possibly exacerbated by an undersized gaspipe.
