Operation
The Premier Loline is an indirect drain back solar Loline (collectors at roof level, cylinder at
ground level) water heater. The fluid in the collector circuit is isolated from the potable
water in the cylinder, hence the term ‘indirect’.
When there is insufficient solar gain or the cylinder is fully heated the pump is turned off
allowing the heating fluid in the collectors and pipe work to ‘drain back’ to the central heat
exchanger within the water heater.
