For daily pool users, turning the thermostat down a couple of degrees, instead of turning the heater off overnight, tends to be best for saving energy in most situations.

    Benefits Of A 400000 Btu Pool Heater

    What is the best electric or natural gas heater for 18′ round above ground pool?

    Those will a large pool will never regret buying a 400000 BTU pool heater. Were going to discuss their main benefits, but first have a look at the table below, created by professionals. It shows what size of heater youll need depending on the water in your swimming pool and its total surface area.

    Pool Heater Size / Gallons In Pool / Surface Area

    • 100-200 BTU / 1,000-10,000 / Up to 300 sq ft
    • 200-300 BTU / 10,000-20,000 / Up to 500 sq ft
    • 300-400 BTU / 20,000-40,000 / Up to 800 sq ft
    • 400 BTU / 40,000-80,000 / Up to 1200 sq ft

    When youre working out the size of your pool its always better to focus on the gallons of water inside it. The surface area can be a big help too, but it obviously doesnt account for the depth of the water. If your swimming pool is a little deeper at one end it could add thousands of gallons onto the total.

    Did you know there are 7.5 gallons of water in a cubic foot? Remember this number because its extremely important. If you want to work out how many gallons are in a constant depth pool you would use this equation:

    Length x Width x Depth x 7.5 = Total Gallons

    If you have a shallow end its also possible to use this equation to give you a rough estimate:

    Length x Width x Average Depth x 7.5 = Total Gallons

    Gas Pool Heater Sizing

    Gas pool heaters are rated by BTU or British Thermal Unit output which is the amount of energy transferred to heat energy. The US Department of Energy has regulated pool heaters to have an efficiency rating of at least 78%. An example is a heater that puts out 200,000 BTUs and has an 85% efficiency rating would produce 170,000 BTUs per hour.

    All pool heaters have a BTU rating and will be listed prominently by the manufacturer. The BTU output is important in determining the size of heater required to heat your pool. The ideal rating is dependant on the surface area of your pool where the larger the surface area of your pool is the higher BTU output required.

    A tip when shopping for a heater is to consider a 10% higher BTU rating than required just to be sure you have adequate heating during times of higher demand and at the beginning and end of the season. If you purchase a larger heater you will heat your pool faster, use it less often and potentially increase the life of your heater.

    Hayward Hp21404t Heatpro Titanium 140000 Btu Heat Pump

    Raypak 014938 206000 BTU Digital Natural Gas Pool Heater with Cupro ...

    Best Electric Heater

    With corrosion-resistant and durable materials, Haywards HP21404T HeatPro Titanium heat pump is our top pick for the best electric heater. Its heating efficiency is undeniable, and we like that it operates quietly to raise pool temperatures quickly.

    Set the temperature you want, and the heater kicks on automatically to make it happen.

    One potential pitfall is how heavy this unit is, weighing in at 250 pounds. Of course, this is only an issue at the time of delivery and installation. Once its in place, the heat pump can handle nearly any environmental condition or pool size all year round.

    • Provides 140K BTU of heat
    • Resistant to weathering and environmental conditions


    • Very heavy at 250 pounds
    • The user manual is lacking

    What Size Of Swimming Pool Heater Do I Need

    In order to calculate the size of swimming pool heater you need to effectively heat your pool, our team suggests that you first calculate your pools surface area, which is the Pool Length x the Pool Width. We then recommend you divide the surface area number by 3 and then multiple it by 1000 to discover the amount of heater BTUs needed.

    For example, if you have a 20 x 30-foot swimming pool, your pool has a 600 sq ft surface area. 600 divided by 3 is 200 and then 200 x 1000 = A minimum 200,000 BTUs heater recommendation.

    Best Budget: Raypak Pr106aenc 105000 Btu Heater

    Pool Type: Inground or above ground

    Pool Size: Up to 10,000 gallons

    A heated pool may feel like one of lifes luxuries, but it doesnt have to be your biggest summer splurge if you shop for a budget pool heater. The Raypak PR106AENC is an affordable gas pool heater that offers 105,000 BTU to heat pools that hold up to 10,000 gallons of water. Its compatible with both inground and above-ground swimming pools. Raypak also makes this analog gas pool heater with increased BTU capacity for larger pools.

    This frills-free model includes an analog dial to set the target water temperature. Other pool heaters on the market often have an LCD display with digital temperature control, but this version relies on a turn-knob to adjust temperature settings. Inside the unit, Raypak has equipped this model to have a long life of service. Stainless steel burners and a copper-fin-tube heat exchanger are designed for durability despite wet working conditions.

    Pool Type: Inground or above ground

    Pool Size: 15,000 gallons

    Above ground pools dont have the benefit of ground insulation, as is the case with inground pools. To keep pool water at an elevated temperature that makes swimming earlier or later in the season more pleasant, consider investing in an above ground pool heater.

    Hayward Heatpro Titanium Best Electric Pool Heater

    6 Best Natural Gas Pool Heaters 2018

    If you do not have natural gas that you can use to run your pool heater, or you dont want to use natural gas, there is another option. The Hayward HeatPro Titanium is our top choice for the best electric pool heater. This model is a heat pump and not a heater, but it is perfectly capable of warming your pool.

    Just like our best overall choice, this Hayward model also comes with a corrosion-resistant evaporator fin. Even if you live in a coastal area where salt can destroy all things, this Hayward heater will stay looking good for years. Although the Hayward HeatPro comes in several different sizes, this model is best suited for a smaller sized pool. It doesnt have the same power as our best overall choice.

    Another great benefit of this model is that it is quiet. Some pool heaters, especially larger ones for big pools, can be extremely noisy. This model has a profiled fan blade to help with efficient airflow and a quieter experience for the user.

    If electric heat pump is the best option for you, then the Hayward HeatPro Titanium is a model that you should very seriously consider.

    The Eco Smart Electric pool heater is a tankless pool heater. This unit is very compact. With a digital display that makes it very easy to use, you can quickly change the settings that you want your pool to be set to.

    Best Gas: Raypak Pr266aenc50 266000 Btu Natural Gas Heater

    Pool Type: Inground

    Pool Size: 25,000 gallons

    This pool heater is fueled by gas, which is a convenient fuel source for many homeowners with an existing natural gas line. Raypak is a leading name in pool heaters. Model PR266AENC50 is equipped with features that make the heater easier to use while improving durability of the unit, such as digital electronic ignition.

    A copper fin tube heat exchanger is typical for many gas pool heaters. However, Raypak adds an additional layer of protection against corrosion of rbis important component by adding a special component to the header, known as a ProTek shield. This module is intended to absorb corrosive materials before they reach the heat exchanger. As a result, its intended to break down over time, but is easy to replace and protects the heating element inside. In addition, this model is equipped with an electronic ignition that only fires when heat is needed. In comparison to a millivolt pool heater, which requires a pilot light to be lit at all times and burns fuel continually, the electronic ignition is more efficient and economical in terms of fuel consumption. however, this gas pool heater will need a nearby 120V or 240V power source.
