Worcester green star 30si fault

[Phil Redmond]

We have a Worcester green star 30si boiler
Hot water is fine.
Ch temp is set at 70 degrees but boiler heats to 68 quite fast then takes ages to heat to 72 when it finally pumps round system,
Seems to be on constant low burn?

Tbh should be max 65 c for heating

If I set it to 65, it hats to 63 then slowly climes to 67 before pumping the water round,
BG are coming to service it in a couple of weeks so hope they find something.

That’s normal tbh won’t go into max burn on ch
