Whether you have an indoor or outdoor swimming pool, you may have to shut it down as soon as the first signs of winter show. It’s essential to heat your swimming pool to optimize thermal comfort. Talking about water heating, electric water heaters are the most efficient. They heat faster than solar heaters and are less expensive to run than the gas-powered types. So, what is the best electric swimming pool heater to buy?
Electric Pool Heaters: Top 6 Review
Below we will see the 6 best electric pool heaters available on the market right away.
1. Hayward 45,000 BTU HeatPro Heat Pump
Coming at number 1 is the Hayward HP50HA HeatPro. This model is a heat pump with a 45,000 British thermal unit (BTU). Super quiet, the heat pump has gone through a rigorous and comprehensive process that ensures you only get the quality you deserve.
The HeatPro comes with a 2-year long warranty and 10 years on the exchanger. You have a titanium thermal heat exchanger that makes it run super efficiently. The heat pump is built so that when the pool water is heated, minimal energy is expensed in the process. Meanwhile, seeing that this has just 45,000 BTU, it is only suitable for small pools for above ground pools with a water volume of up to 13000 gallons.
2. Hayward W3HP21004T Heat Pump
The Hayward W3HP21004T Heat Pump has 140,000 British thermal unit capacity. But it is available on the market at a lesser price than what is the standard. However, the model is available in two variants – the 90,000 and 140,000 BTU models. The ratings mean the pump will heat your pool better than the HeatPro heat pump. You don’t need to have the machine on overnight so it can be usable in the next morning.
The process of heating the water causes the pump to release cold air above it. This heat pump needs a clearance of at least six feet above. The devices heat the pool water using the air surrounding it, so you need clearance on all sides. But the most space is required above the heater.
3. Raypak Digital Natural Gas Pool Heater
This is a series of Raypak digital pool heaters powered by natural gas. The series comes in three different British thermal unit capacities. These include the 266,000 BTU, 336,000 BTU, and 406,000 BTUs. The heaters feature a nice, easy-to-use digital panel. You can raise and lower the temperature. You can also change the mode of the heater.
The Raypak model has an on/off ignition switch. Included with the heater are the installation and operation instructions. Also included are two CPVC unions for the heater. If you need to access the inside of the heater, it features a front panel that will easily open. So this makes repairing very easy and convenient. Situated on the other side of the heater is a cutting-edge module that sits in the header of the heater. This protects the heat exchange from corrosion. So this heater is excellent for saltwater pools, and to add to the durability of this heater, it features a polymer header.
4. FibroPool FH055 In-Ground Swimming Pool Heater
This heat pump is a compact unit which is easily wired and plumbed. We’re delighted with the quietness of the compressor and fan. Its control panel is pre-set. You wouldn’t need to change the default settings. The product features a box and a cable.
It works well for inground pool of up to 10,000 gallons of water capacity. The equipment can also heat a 21-foot round pool or a 15 feet by 30 feet oval pool. FibroPool utilizes the high-pressure Copeland differential compressor and a titanium exchanger. This makes the heater achieve a coefficient of operation (C.O.P) of 5.92.
5. FibroPool FH 220 Swimming Pool Heat Pump
The FibroPool model is a reliable heater for a small pool. The model comes from a very knowledgeable brand that provides exceptional after-purchase service.
What we like most about the heat pump is its ease of installation. It also has excellent tech support, is energy efficient, and comes with 4.85 COP. Considered one of the most efficient within its class, the FH 220 produces a heating capacity of just 20,000 BTU every hour. The product is ideal for swimming pools of up to 7500 gallons if the pool is located in a coastal area.
6. Hayward 11kw Electric Spa Heater
This Hayward spa heater has 11 kilowatts of power. Although the equipment is marketed as a spa heater, you can use it as a pool heater. However, the model is kind of tailor-made for spas. The Hayward model is an electric heater, so it’s not necessarily going to be as efficient as gas can be. But for places that gas isn’t an option, this is very efficient. For an electric heater, it will shave quite a bit off your electric bill. This thing operates on 240 volts, and it’s rated to heat about 70 gallons per minute maximum. What that means is it’s pretty powerful for even smaller or medium-sized hot tubs.
It’s ideally tailored towards in-ground tubs as most above-ground tubs have built-in heaters. But you may be able to retrofit it in there. Hayward has been making these things for a long time. They’re the industry standard as far as quality goes. They use 100% stainless steel tanks inside. This is particularly a very well-built machine that’s very simple to use. You just need to turn the dial to whatever heat you want. It can’t be any simpler than that!
We’ve recommended to you 6 top models to buy. Do you have a few questions concerning the heating equipment? We will provide you with more purchasing information in this section. Here are some essential features to watch out for before choosing your pool heater.
The flow rate is an indicator of the operation of the pump. It indicates how many liters of water can be pumped through the machine and warmed up in 1 hour. This can range from 4.4 GPM (1.5m³ per hour) to 110 GPM (25m³ per hour). This all depends on your needs.
The Heating Capacity/pool Size
The larger your pool is, the more powerful the pool heater should be. If you want an electric pool heater, you need to make sure that the wattage is suitable for the size of your pool. For a small 7,500-gallon capacity pool, you can choose models with 20,000 to 45,000 BTU. For larger pools from 10,000 to 25,000 gallons of water, there are heaters ranging from 90,000 to 400,000 BTU.
The maximum heating system is the main performance criterion for a swimming pool heating system. It shows how many degrees Celsius the temperature can be raised with the heating unit. Just like the cleanliness of the swimming pool, pleasant water temperature is also critical to achieve a pleasant swimming experience. Your pool heater should be able to achieve a 16 degree Celsius temperature in 24 hours.
Pool heating can be particularly noisy. To avoid inconvenience, it is recommended to find out about the decibel level of the model. Usually, the sound levels are indicated on the product sheet, and shouldn’t exceed 60 decibels.
Frequently Asked Questions:
Q: What size electric heater do I need for my pool?
A: To know the minimal BTU size to buy, divide the surface area of your water facility by 3. With a 15 by 30 pool, you have 150. The minimum size to buy is, therefore, 150,000 BTU. However, always add 20% to the volume of your pool. That is, the optimal heating size you need, using the reference above, is 180 BTU.
Note that if you undersize your heater, you expose yourself to 2 problems. The heating will not be sufficient to maintain the water at the ideal temperature. Also, your heat pump or electric heater will run almost non-stop. It, thus, will consume a lot more electricity than with an appropriately sized one.
Q: How long does it take to heat a pool with an electric heater?
A: This depends on the compatibility of the heater’s power to the pool size. If you find the right balance, your heater should be able to heat your spa up to 11 degrees Celcius in 1 hour maximum. For an average pool, this can take between 1-3 days.
Q: Are electric pool heaters expensive to run?
A: Electric pool heaters aren’t expensive to run when compared to other types such as the propane and natural gas heaters. After solar heaters, electric heaters have the cheapest cost of running. Depending on the pool and heater size, it will cost you around $200 to $400 a month. However, for Florida, at 0.09/kwh, you’ll spend roughly $1,450 annually, as you wouldn’t need much heating in summer.
Q: Do electric pool heaters work?
A: Electric pool heaters are one of the most efficient types. Although they’re more expensive than gas-powered types, they’re cheaper to buy and more powerful than solar models.
Electric pool heaters provide suitable isothermal protection for your facility during unfriendly seasons. However, the best electric pool heater for you depends on your location and your pool size.
