Hot water only when heating turned on

Welcome to the forum. Although you can post in any forum, the USA forum is here in case of local regs or laws

Hi, we have an HIU unit, which we only get hot water from the taps when we turn on the heating unit. A number of engineer have come in to check but they have stated they couldn't see any issues. Any thoughts? could it be the heating plate?
