How do you heat a cheap intex pool?

Use a solar pool heater. This is the most cost-effective way to heat your pool, as it uses the sun's energy to warm the water. Solar pool heaters are available in a variety of sizes and shapes, so you can find one that fits your pool and budget.

Use a heat pump. Heat pumps are more expensive than solar pool heaters, but they are also more efficient. They use electricity to transfer heat from the air to the pool water. Heat pumps can be used to heat both above-ground and in-ground pools.

Use an electric pool heater. Electric pool heaters are the most expensive way to heat your pool, but they are also the most convenient. They can be used to heat both above-ground and in-ground pools.

Use a gas pool heater. Gas pool heaters are less expensive to operate than electric pool heaters, but they require a gas line to be installed. Gas pool heaters can be used to heat both above-ground and in-ground pools.

Use a wood-burning pool heater. Wood-burning pool heaters are the least expensive way to heat your pool, but they require a lot of maintenance. They can be used to heat both above-ground and in-ground pools.

Additional tips for heating your pool on a budget:

- Cover your pool when it's not in use. This will help to prevent heat from escaping.

- Place your pool in a sunny location. This will help to maximize the amount of solar energy that is absorbed by the water.

- Use a pool blanket. A pool blanket will help to keep the heat in the pool at night.

- Turn off the pool pump when it's not in use. This will help to save electricity.

- Consider using a pool heat pump. Pool heat pumps are a more energy-efficient way to heat your pool than traditional electric or gas pool heaters.
