How to Buy Best Pool Heater

How to Buy Best Pool Heater

So, we will now procced this pool heater review and mention some of the significant tips to help you buy the most efficient pool heater.

#1. Type of Pool Heater

If you have been following our guide since the beginning then you must know about all the different types of pool heaters.

However, we will share a comprehensive theory on each on of it.

Solar Heater: We will start with the most budget friendly option in the market which is the solar heater. Well, it is run by the sun energy.

Used by the solar panels that are installed in a place where there is direct sun, this heater consumes a lot of energy in the day time and then heat the pool water eventually.

Water is first circulated from the pool into the panels where it is heated up and then recirculated to the pool.

The heater is not recommended for the people that live in wet places that experience rains most of the time of year. It works best in sunny areas.

This can be an auxiliary option but if you like swimming a lot then we don’t really recommend it. The reasons are the it is slower than the counterparts plus not as effective.

Pros:

  • Do not use electricity at all which means no additional operational cost
  • Environment friendly
  • Very durable

Cons:

  • Climate-centric means it won’t work if there is no sun
  • Very slow in heating up the water

Natural Gas/ Propane: If you want an uncompromised heater option and are willing to spend a high amount then, natural gas or propane heaters have no substitute.

The heater uses combustion chamber to heat up the water. The water is passed through a super-hot tube channel and when it returns to the pool, the temperature is already up by 30 degrees.

Now, the drawback is the while these heaters are absolute winners, they come with huge price tags. But, they don’t require long operational time i.e. you only have to use them for hours before diving inside the pool.

Pros:

  • Impeccable performance
  • Durable
  • Quick in heating up the water

Cons:

  • Expensive than the counterparts
  • Not environment friendly because it diffuses harmful gases

Electric Heater: Well, this is the most common type in this category. Clearly, the electric heater runs on electricity.

These heaters are less expensive and conveniently installed, yet the drawback is that they are not energy efficient. You can expect huge electricity bills. If you don’t mind paying the hefty bills then this heater is for you.

These models are suitable for in-ground as well as above-ground pools.

Pros:

  • Durable  
  • Don’t release harmful emissions
  • Less expensive

Cons:

  • Takes a lot of time to warm up the water
  • Not energy efficient

Heat Pumps: So, a heat pump is based on quite unique phenomenon where the heater pulls warm air from the surrounding and compressor optimize it to the right temperature. Technically, they run on electricity which is used to collect the air.

As a result, the air is heated and sent to the pool water. This way, you enjoy one of the safest and eco-friendly ways to heat up the pool. Irrespective of the pool size, the heat pumps can efficiently work with them.

These are expensive than others however, the efficiency is also worth-appreciating. The operation cost is very less.

Pros:

  • Pretty Efficient  
  • Don’t release harmful emissions
  • Less Operational Cost

Cons:

  • Very expensive
  • Takes a lot of time

Buying Advice

People that on strict budget can make a choice between solar, natural gas and electric heaters. While the upfront cost for electric and natural gas heaters is less than the heat pumps, they demand huge operational cost.

At the same time, if you wish to go energy efficient and require a highly suitable heater then pick the heat pump. But be ready to spend some hefty amount of money on the initial purchase.

#2. Size

We would like to elaborate the point of size with a simple table below. Most of the heaters comes with their respective heating performance. From there, you can assimilate the surface area covered by the heater and amount of water that it is capable of heating.

Size of Heater in BTUs

Surface Area (In Sq. Ft)

Gallons of Water

100,000 – 200,000

Up to 200

1000-5000 gallons

200,000 - 300,000

200 – 300

5000 – 10000

300,000 - 400,000

300 – 500

10000 – 20000

500 – 800

20000 – 40000

500,000 or above

800 - 1200

40000 - 80000

#3. Type of Pool

There are two types of pools, In-ground and Above Ground. The requirement of heaters is different for both the types of pools. However, there are some heaters that are cordial with both the types.

In-Ground Pool Heater: Some of the heaters are classified as best in-ground pool heaters for a reason. Such units are more powerful, have high BTU output and are energy efficient.

There are no such thing as in-ground pool heaters as such because all the kinds such as solar, natural gas, or electric heaters can be installed in such case.

However, the strength and water heating tendency of a heater makes it suitable for in-ground or above-ground usage.

Above Ground Pool Heater: Identically, all kind of heaters are suitable for above-ground pools as well.

The capacity of above-ground pool is usually less than in-ground pools. That is why, these require mediocre sized heaters unless you have a massive pool with capacity of 40000 gallons.

Mostly we recommend solar pool heaters for above ground pools.

Buying Advice

For any kind of large pool, we don’t recommend electric heaters. They will charge massively and the power expenses will multiply. Solar heaters are also not suggested for the same because they are not as effective.

#4. Price

This section has two main parts. First is the initial expense that come while purchasing the product. The second is the operational cost of the heater.

Other than the solar heaters, none of the other options come without any operational cost. Electric heaters have less initial cost but the bills are increased.

At the same time, you can expect an expense of around $500 per month in case of gas heaters. The heat pumps also run on electricity so they also cost a lot later.

Conclusion

So, we would like to conclude our pool heater review by saying that there are various options available in the market but you cannot rely on all.

The models that we have mentioned above are great in their class. If you want to purchase a fine solar heater then Fafco or SmartPool products are quite suitable.

You can also check out electric pool heater review of EcoSmart, Haywards, or FibroHeat products that are extremely efficient in working.

As per your requirements and budget, pick any model mentioned above and you will not have to regret the purchase ever.

Happy Shopping!
