DIY Solar Heater Lily Pads

5 Materials
20 Minutes

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.

    Will this work for inground pools?

    This is simply too unsightly to consider. With the current nationwide heat wave, where do you live that your pool water is too cold to swim in?

  • Becky Becky on Jul 27, 2023

    Could you put the pool noodles on the hula hoop before placing it in the bag?
