The Hayward H250FDN Universal H-Series BTU Pool Heater is our pick for the best overall pool heater. Amazon customers gave it a rating of 4.3 out of 5 stars. The H250FDN is also part of our list of the best heaters available online.

Featuring a standard cuprous nickel heat exchanger, the H250FDN quickly heats the pool for you to enjoy even on cold days. It has a flexible universal fit for new and existing installations and a modern, low-profile appearance. The heater is also designed for both left-side and right-side electric, gas and water connections and comes with a 110v or 220v electric hook up.

The H250FDN is easy to use and comes with a digital LED control panel, featuring hydraulic performance for reduced circulation time.

  • Easy to install
  • Compatible with most pool pump


  • Can only raise temperature up to 10°C
  • You only get 2 panels for the price

For the best budget-friendly heater, we recommend vidaXL's Solar Pool Heater. On Amazon, it has a rating of 4.1 out of 5 stars.

This solar panel utilises the sun's rays and converts them to heat, keeping your pool warm in a cost-effective way. The pack comes with a pair of 80cm x 620cm panels with a width of 34cm. It is suitable for most pool pumps. It can also be mounted on a roof or rack or simply laid on the ground by the pool.

Customers praised the product's value for money, ease of use and durable build. It is ideal for small to medium-sized pools. For larger areas, you might need to buy an extra set of solar panels. It quickly and evenly warms the water, but it doesn't help raise the temperature beyond 10°C. Despite this minor setback, this option remains a popular choice for buyers on a budget.

Types of pool heaters

A pool heater is a handy little device that warms up your pool's water for you to enjoy even on cold, winter days. It comes in various types, such as gas, solar and electric.

Gas heaters utilise energy from burning natural gas or propane to warm up a pool. These options are popular because they're quite powerful and provide a fast heating time. They are suitable for most pool sizes, especially larger ones. However, it requires installation by a licensed professional, which can be costly.

Compared to gas options, electric heaters are easier to install. You don't need to connect an electric heater to a gas line for it to work. An electric heater uses ambient temperature to produce warmth and keep your pool water at a comfortable and toasty temperature. However, these models are typically more expensive.

For a more environmentally friendly option, solar heaters are your best bet. These capture the sun's rays and convert them to energy to heat the pool water. They are simple to install, too. You don't need to hook a solar heater to any energy outlet. But you have to ensure that the heater's solar panels are efficiently positioned where they can get the most sun exposure. For night swimming, you need to purchase a diverter for a solar heater to work.

How to compare pool heaters

Consider these factors when shopping for a pool heater:

Pool size

Not all pool heaters are created equal. Determine your pool size so you can identify the type and size of the heater you need to keep it warm and cosy.


Choose between electric, gas or solar heaters. Gas options are the most powerful, while electric heaters are easier to install. Solar heaters are the most cost-efficient, but they may be unsuitable for night use.

Coefficient of performance

This is the ratio of the useful energy the heater produces to the energy it consumes. COP can also translate to lower operating costs.

Temperature range

Some heaters may not be suitable for extremely cold climates. Check the heater's operating range of temperature to find the best option suitable for your climate.

Heat-up time

Check the heating rate of the pool heater before purchase. Some models heat pool water on demand, while others require at least 12 hours.

Noise levels

Nothing is more annoying than a loud heater while you try to relax. Pick a heater with a near-silent operation so you can better enjoy the warm water during cold, winter days. Fortunately, most brands offer pool heaters with low noise levels.

Improving your pool heater's efficiency

Here are several tips to improve your pool heater's efficiency:

  • Use a cover. Evaporation causes your pool water to get cold fast. Using a pool cover can prevent heat loss when not in use.
  • Run your heat pump at a low speed when the heater is off. This will help you avoid reheating your pool water every day during colder weather.
  • Adjust your temperature. Adjust the water's temperature depending on how you use it. For active swimming, up to 28°C may be more than enough. If the pool is on standby, you can bring down the temperature to 23-25°C.
  • Regularly clean your pool. Clean your filters and baskets every other week to ensure your pool water circulates properly. This will help your pool heater's efficiency.
