The issue with oil heaters is operational cost. My place warmer than the op description ran 400 a month to heat (poorly insulated)

I use dual uth and a light system to hold ambient temps IR lamps are ok but I'd suggest either deep blue (out from the bp visual range) Che for efficiency. Personally I use a combo of fluorescent lights and deep blue led lights. And insulated PVC enclosures. I often am in the low 60s and I hold temps fine. I suspect however that as far below this as you have will overwhelm all of the above and some combo of enclosure additional direct heating as well as increased room temps will be needed.
