So i have an 18foot intex easy set pool. And an free 5.5kw hot tub heater i got for free. I did some calculations it is seems like it will function to my needs. I am only going to use it to bring the pool up maybe 10 degs on some weekends at the start and end of the season. I know it is way undersized for the pool. Does this seem like it will be effective. Or will it loose its faster then the heater can maintain? We aslo use a soler cover.
Thanks.
