Best Above Ground Pool Heater in 2022

Above-ground pools offer you the convenience of having a pool to keep cool during the hot summer months at a fraction of the cost of building a pool. Not to mention, they are easier to clean and maintain. And you can move with them as compared to an in-ground pool.

However, heating an above ground pool is tricky. On account of the exposed wall, the water loses heat faster as compared to an in-ground pool. For this reason, you need a heater that can heat the water quickly so that it can have more cycles for optimal heating.

This means you need to get an efficient pool heater and energy saving as the more cycles will tend to consume more electricity. Here are the best above ground pool heaters in the market currently.
