Solar Chicken Water Heater


What is a solar water heater for chickens?

How does it work?

Why might you need a solar chicken water heater?

A solar water heater intended for chickens is simply any kind of heater that is designed to keep your chickens’ water from freezing when the temperature drops at night. With this type of heater, your chickens’ water should stay warm enough to prevent ice from forming, so your chickens always have access to it.

These types of DIY solar water heaters work by using the ambient heat of the sun to keep the water warm. They require an enclosed space and some sort of absorbent material to help raise the temperature around the water dish.

From there, the sun does most of the work and keeps the water warmer than the temperature outside.

These solar heaters are easy to build and don’t take long to construct. In this article, we’ll show you a quick DIY version of a chicken solar water heater that many DIYers are sure to enjoy building.

By following these directions, you can give your chickens a better and more efficient method of finding fresh water, even when it’s very cold outside. And best of all, you don’t have to pay a lot to put this project together, either!

Read on to learn more about how to build a solar water heater chickens can enjoy.

Materials and Equipment Needed

Before you begin working, you’ll need to gather the materials and equipment required to complete the job. Make sure you have all of these items on hand as you begin, so you don’t have to stop in the middle of the project to stock up.

  • 3 total patio blocks, 12-inch square size
  • 1 (2×4) wood block, 10-inch length
  • Outdoor-safe adhesive
  • 12×18 piece of Plexiglas
  • Black rubber bowl
    • Alternately, you can use any rubber or plastic bowl that is painted black with animal-safe paint.
  • Circular saw
  • Adhesive gun
  • Aquarium thermometer
  • Safety gear: goggles, gloves, closed shoes, safety mask.


These directions are intended to help you build one style of chicken water heater. There are other methods out there, but this is the most beginner-friendly. By following these instructions, you’ll be able to construct a chicken water heater in just a few hours and start using it right away.

1. Cut one of the three square patio blocks diagonally using the circular saw.

2. Use the outdoor-safe adhesive to attach one of the uncut patio blocks to the other at a 90-degree angle. This will form the back “wall” of the water heater.

3. Use the adhesive to then attach the two diagonals so that their points fit into the corners created by the two intact patio blocks. You should have a small container with two slanted sides, a back wall, and a bottom.

4. Wait a few hours (or the amount of time listed on the outdoor adhesive) until the blocks have bonded firmly to each other.

5. Use the circular saw to cut a 10-inch length piece of a 2×4.

6. Attach the 10-inch wood block using the outdoor adhesive to the center of the structure you have constructed out of patio blocks. The wood block should act as a shelf that sits about halfway up the height of the sides and against the back.

7. Let this shelf dry or bond as needed until it holds firmly in place.

8. Use the adhesive to attach the Plexiglas to the front of the structure. The Plexiglas should allow light to shine through and heat the patio blocks, therefore heating the water inside as well.

9. Wait for this to dry and bond fully as well.

10. Use the saw (or any other cutting tool you choose) to cut a hole in the front of the Plexiglas sheet. This hole should allow the water dish you have chosen to fit snugly inside, but shouldn’t be much larger. Use the watering dish itself to measure how wide and tall the hole needs to be.

11. Place the black rubber watering dish inside the container, on the wooden shelf.

12. Place the DIY solar heater in the part of your chicken yard that receives the most sunlight throughout the day. Make sure you don’t put it in a place with too much shade, or it won’t do its job.

13. Use an aquarium thermometer to measure the temperature in the bowl throughout the day. This type of thermometer can be placed either directly in the water or on the side of the bowl to measure the temperature within. You can use this information to determine whether or not the DIY heater is going to keep your chicken water from freezing.


Do you feel like you learned something about how to make a solar water heater for your chickens? This project can be a fun one, and it doesn’t require a lot of skill to complete, either. As long as you feel comfortable operating a circular saw—or you can ask a friend, family member, or hardware store to do the cutting for you—then you should be able to complete this project with no trouble.

Putting together a chicken water heater may be a great way to provide your chickens with warm water all year long. Keep the following tips in mind to make sure you always construct the best solar heater for your chickens:

  • There are many different styles of homemade chicken water heaters to choose from. The right option for you will depend on your DIY skills as well as your chickens’ needs. You should also choose the style that will allow you to keep your water heated enough to prevent it from freezing in the climate where you live.
  • Pick a DIY heater style that will still allow your chickens easy access to their water. Some chickens are pickier than others and won’t try to drink out of a bowl that isn’t too easy for them to reach. Keep this in mind, and test the heater in different locations if you notice your chickens are avoiding it after you build it.
  • Finally, don’t be afraid to add more elements to the heater to make it work for you. For example, you may choose to add reflective material to the back or bottom of the heater to help create more heat within the closed space. Doing so can work in some climates, as long as you have plenty of access to sunlight in your yard. You may also want to paint the back or sides of the heater black to achieve a similar outcome.

There are many ways you can alter the design listed above to make it something entirely your own. And remember, there are also plenty of other choices to pick from when building a solar water heater for your chickens. With the right plan in mind, you should be able to set up a heater that will keep your chickens’ water from freezing even after the weather turns cold. And this will mean you’ve got happier, healthier chickens, too!

So gather the materials you need, be sure you have the right equipment, and get started constructing your chicken solar water heater right away!
