At 18 cents/kWh, an inverter ASHP could handle a major part of the heating season, without breaking the bank.
Even during the colder parts of the winter, if the day time temperatures get up above -13C,
it could give you a break from feeding a fire.
Since we have solid fuel capability, we might end up using wood again someday.
If our government continues on it's current path, I foresee a time when
we may not be able to afford to buy luxury items like fuel oil and extra KW hours..
Of course, the local supplies of wood might not last very long with millions
of people feeding ineffective fireplaces..
