Learn how to make a DIY solar pool heater with supplies from the dollar store. Heat your pool by harnessing the power of the sun with this easy tutorial using a pool noodle, hula hoop and a trash bag.

Supplies needed to make a DIY pool heater


Hula hoop

Pool noodle

Black trash bag

Serrated knife

Duct tape

Place the hula hoop in the bag


Place the hula hoop inside the bag and tie it up. Use duct tape to secure it if necessary. You need to use a black bag because black will absorb the heat from the sun and warm up the water underneath the bag. You will use one hoop and one trash bag per heater.

Cut the noodle


Cut the pool noodle into three equal pieces. Cut a slit down the side of each of the pieces. You will use one pool noodle for every solar heater that you make.

Attach the noodles to the hoop


Slide the noodles over the edge of the hoop and use duct tape to secure it in place. Place them evenly around the hoop.

Place the lily pads in the pool


Place the lily pads in the pool. The more you put in the water the better it will work. The sunnier the day is, the better it will work as well. Remove the solar heaters before you go swimming.

Never let children swim without adult supervision.

    I'm wondering if these would float with just the hoola hoop and bag . . . The hoops (and bag) should stay above water because of trapped air.

    Did you try that and it failed?

    will these be toxic in pool water ????

    Will this work for inground pools?
