Pool Heater Buying Guide: Choosing a Pool Heater
This part looks at things you should consider when choosing your pool heater.
Types of Pool Heaters
You can find four types of pool heaters, which we have outlined below:
1. Solar Pool Heater
Most pool owners overlook the solar pool heater due to its high cost of installation. That often makes them miss the best pool heating system as it does not incur operating costs.
A solar heater requires the sun to provide the much-needed heat, but it is also decent when it gets cloudy. You can easily install this heater at the rooftop, on the ground, or fence.
A solar pool heater can provide you with services for over 25 years.
2. Electric Pool Heater
It is rare to find an electric pool heater installed in the most swimming pool because it lacks the economic feel of other types of heaters. Such a heater is not the best for heating large water bodies.
With that said, these models are quite useful when heating an indoor spa and small pools. They work like a water heater by allowing the electricity to heat the heating element.
Another great thing is they are relatively compact, and you can install them in places with limited spaces.
3. Gas Heaters
You can find propane or natural gas pool heaters, and they have dominated the market for years. They are the best systems for warming a swimming pool without wasting time.
These units come in different models, sizes, and designs to meet every pool owner’s needs. The heaters are rated in BTU.
Gas heaters are more comfortable to operate compared to other models out there. One downside of these heaters is a big size.
4. Heat Pumps
It is a new technology that pool owners are opting for when heating their pools. They are quality heaters that warm a pool fast and without using much energy.
These models are friendly to the environment and pools because they do not release harmful gases. The pumps get heat from the air and use it to increase the pool’s temperature.
Features to Look For
Here are features that you should consider when buying your pool heater.
1. Pool Size
A large pool requires a large heater to ensure that the water gets warm overtime.
Here is a guide to help you:
| Surface Area (Sq. Ft) | Pool Size (Gallons) | Heater Size (BTU) |
| 300 | 1,000-10,000 | 100-200 |
| 500 | 10,000-20,000 | 200-300 |
| 800 | 20,000-40,000 | 300-400 |
| 1200 | 40,000-80,000 | Over 400 BTU |
Heat pumps should provide 50K BTU for a 10K gallon pool while electricity on is 300 sq. ft. pool for 150 sq. ft. of panels.
2. Your Budget
Another thing is the buying price of a pool heater and the operation costs. A gas model is affordable when purchasing, but propane and natural gas can be expensive.
A heat pump is also affordable but requires electricity to operate, and that can make it expensive in the long run. Solar heaters are costly to buy but are cheap to operate.

You should also consider the climate. It affects how your pool gets heated.
