If you get Electricity from PECO, consider switching to Time of Use Pricing and heat more with electric heater.

The super-off peak rate (Midnight -6am) is very cheap at $0.02824 per kWh. Meaning one of these 1500w space heater will only cost 4.2 cents per hour during the coldest part of the day.
And Off-peak is only $0.04801 per kWh, so 7.2 cents per hour.
Off-Peak Weekdays: (6 a.m. – 2 p.m. & 6 p.m. – 12 a.m. )
Off-Peak Weekends and Holidays(1): (6 a.m. – 12 a.m.)
Have you thought about buying like 5 of these? They are 65 each, so a one time $300 cost.
