Add % breakdown between DHW and Heating in Heatpump app

[zarch1972]

Would it be possible to add an at a glance percentage breakdown for hot water / heating?

A bit like this mock up that looks at the Heat Output as the driver.

Water Heating Output / Full Heating Output * 100

This total could also then feed into heatpumpmonitor.org charts to give an indication to viewers how much of a homes demand is hot water versus heating.
