4 KW electrical heater? That is quite small, so I'm sure it is running 24/7. That's 2880 kw-hrs per month, at a rate of 20 cents per kwh (estimate - plug in your rate) = $576 per month.
With a 4400 gallon pool that is 10' x 14', and assuming you have a large roof area, you would do well with solar panels. You still might want a small gas or electric heater just to keep things at 82 when its cloudy or particuarly cold, but 4 KW is too small. If it were me, I'd install 240 square feet of solar panels on a south facing roof if possible and you should be able to maintain 82 since you are using a solar blanket.
