Hi all
I’ve had a number off issues with my heatslave 12/18, most recently returning from holiday to find it on lockout with a totally dry tiger loop.
I managed to get it working again by priming the pump via a temporary gravity fed supply. It was then able to draw through oil from the tank.
That’s lasted a week of intermittent hot water use and no heating use. However, this morning I have found the tiger loop completely dry and the pump unable to draw through.
The pump is only a month to 6 weeks old so it is likely just to be air getting in allowing fuel to drain down back into the tank?
