Just to add more details on the above on HW demand the boiler's temperature rapidly raises to 95-99 before making some noise and switching off. Occasionally it displays (errors?) U0, U1, U2 after going through 99. Don't know if these are errors or whether they are meant to indicate 100C, 101C, 102C. Thanks.
