Cost to run heater

Heater info in attached images.

Last year, opened late (memorial day weekend), and never really used the heater. Used it a couple days in late September ( worked fine).

I was just curious on average cost to run these. I know it’s all dependent on your rate per kw charge, outside temperature, your pool water temperature, and the temperature setting you select.
Because it takes a day or two to warm the pool up, I feel like it’s the kind of thing where If you are going to use it, you just leave it on until you don’t need it any more.

I have no idea if, on average, running this thing for a month straight in May (live in SW OH near Cincinnati for an idea of my Climate), would create a HUGE electric bill or not?

If I'm doing the math right ........

When the compressor is running (water is being heated), you'll be using about 7.062 kW (230*32.1).

If you end up heating water for 24 hours/day, and electricity costs 12.5 cents per kWh, it will cost about $22 per day.

Since that's a heat pump, it will be most effective when it is warmer outside. I heated my pool in April from 62 to 82. I had a solar blanket and only ran the heat pump 7-8 hours during warm hours (11-7). After that, I only have to run it for about two hours per day to maintain it and it only costs about $1 a day. You might have to run it a bit longer since I live in the south. But using a blanket will reduce your cost drastically.

Yikes. That’s crazy and not good! I may just wait and use Memorial Day weekend as a target date to use it then..gives me plenty of time to SLAM it and stabilize. Not worth $22 a day!

That looks like an older model 130k btu heat pump...figure about a dollar an hour to run.
