If you had no gas, what do you estimate your monthly heating bill would be in addition to the $125?
I'd say 95% of the heat comes from the heat pump and baseboards now so it wouldn't make much difference to winter time bills. Maybe another $10?
If I got rid of the gas entirely I estimate the $500 I'm currently spending on it would more or less migrate across to the hydro bills to make the total bills about the same. Would just simplify my life without having to fiddle with gas appliances and having my house not explode when the big earthquake hits.
