I'd keep the heater running. 8-12C is too cold in flower, especially with a canopy already stacking like that. At those temps the root zone slows right down, nutrient uptake gets lazy, and the humidity jump at lights off can put moisture into the buds even if the daytime numbers look fine.

You don't have to hold it at 22.5C if power is the issue, but I wouldn't let it keep dropping into the low teens. Something around 18-21C lights off with steady airflow is a lot kinder. Also keep the heater from blowing straight on the plant or the pot, just warm the room/tent air.
