How to Warm Up an Inflatable Swimming Pool

Quck answer

Heating a blow-up swimming pool can be done using various methods. One option is to use a solar cover, which helps to trap and retain heat from the sun. Another option is to use a pool heater, such as an electric or gas heater, which can quickly and efficiently heat the water. Additionally, a heat pump can be used to extract heat from the air and transfer it to the pool water. Lastly, a DIY solar heating system can be created using black hoses or coils to absorb sunlight and warm the water. Choose the method that suits your needs and budget for a comfortable swimming experience.


As summer approaches, you may consider getting an inflatable swimming pool as a cost-effective way to stay cool and have fun with your kids. However, the water in the pool can be cold and uncomfortable, especially after cleaning or setting it up. Luckily, there are a few simple and affordable methods to add some warmth to the pool.

First, you need to set up the pool according to the instructions provided. Inflating it using a bellows or electric air pump is usually sufficient. Once the pool is set up in a sunny area, you can proceed to warm it up.

One way to warm up the pool is to let the natural warmth of the day do the work. Simply fill the pool with tap water and place it in a sunny area. Over time, the water will adjust to the air temperature and become warmer. This method is slow but energy-efficient, and the water will be warm by the time the day gets hotter. However, it may also cool down quickly once the sun goes down.

Another option is to use an inflatable pool heater. This simple and inexpensive device can help raise the water temperature above the ambient temperature. Alternatively, you can use a solar sun ring, which floats on top of the water and absorbs heat from the sun. This method not only heats the water but also insulates it to prevent temperature loss and evaporation. One solar sun ring is usually sufficient for most small inflatable pools.

If you have access to a hot water outdoor spigot, you can also use it to fill the pool with warm water. Some outdoor spigots have both hot and cold water options, making it convenient for various outdoor needs, including filling up the pool and giving your dog a warm bath.
