Do many people heat their pools when it is 6 degrees out? If they did, it would not be with a heat pump. Winter Pool heaters are huge 400,000 or more BTU monsters using propane or Natural gas. That's about 4 times the size of an average home furnace.
Oh you have 1000 square feet? You only need a 1.5 ton heat pump. Assuming it uses half the electricity of a 3 ton unit, You can scale it back to 48 batteries at $150. That is only $7200 in batteries. That is way more than 6 years of my gas bill in a 3800 sq ft house. Now assuming you ran the batteries down 100%, you could get by with 24 batteries which is still $3600, Of course you would have to replace them yearly since they don't last long when fully depleted on a regular basis and there is no way your solar panels could recharge them every day 100% unless you have you yard covered with them as well.
Since you are not able to post the info about the batteries or the heatpump, we will assume you made it all up. You must be a marketing or political science major, assuming you graduated high school.
