Biasi riva M90e 24s

works perfect for hot water!

comes on for heating for about 15secs and doesn't ignite again for 5 mins.

changed thermistors and pump!
hmmmmm???

Do the rads get hot? Flow return temps when it is running? you have changed the pump but there may be a Div valve issue, have you checked it?

Kettling/overheating???

Give us some more info and we may be able to help.
