What’s a Pool Heater?
Just as hot water is needed for doing laundry or dishes, showering, you might like to find hot warm for your backyard pool beneficial. Since your household water heater is not meant for swimming pools or spa, you need special equipment known as a pool heater.
This pool equipment can come in handy for pool owners in colder areas and love to keep swimming during these cold times for weeks or even months. However, there are several factors such as type, water temperature, size, and even brand that can influence your decision on the type of heater to purchase. Picking the right pool heater can be a bit tricky.
Choosing a unit offering more power than your pool needs, which costs you more in terms of initial cost as well as monthly bills. Similarly, using a smaller heater for a large pool can be a waste of money, as the unit will not be able to increase the temperature of the water to your preferred level.
Types of Pool Heater
There are several different kinds of pool heaters, with each having its upsides and downsides. Without further ado, let’s take a quick review of these types before reviewing the top 5 best of pool heaters on the market.
Solar Pool Heater
Just as the name implies, this heater runs on solar energy. It’s powered using solar panels, which capture solar energy and transfer it into the pool to increase the water temperature. This type of heater is not a fast option and depends entirely on the intensity of the sun.
While solar pool heater has a very high initial cost, there’s no monthly bill, and above all, little to no maintenance is required. Besides, if you are concerned about eco-friendliness, then this unit won’t disappoint.
Further, they are an excellent choice for those living in a place with extreme sunlight and are not looking for budget-friendly equipment. Moreover, this is a worthy investment that will serve you for long and save money over time.
Electric Pool Heater
This should be simple to figure out; the equipment is powered by electricity. They are super fast and will heat your pool water quickly all year round.
Electric pool heaters are ideal for those you don’t have issues paying high monthly electricity bills and always want the pool heated up as fast as possible.
Electric Pool Heat Pump
These innovative equipment run off of your electrical connection, similar to an electric pool heater. However, they are slightly different as they don’t heat but takes advantage of the surrounding air temperature.
These models are durable, long-lasting, and won’t leave you huge monthly electricity bills to pay. They are an excellent choice for pool owners with a surrounding temperature that’s always above 40 degrees. Sadly, during the colder weather, it will be less efficient.
Natural & Propane Gas Heaters
This option has been in the market for a long time. Sadly, its demand is crippling because of the increasing price of gas over the years. They use natural or propane gas. The water gets to the heater after being filtered. The gas burns in the heating chamber, which transfers the energy to the pool water. Therefore, the water becomes hot and flows back to your pool.
Among the types discussed, this equipment is the cheapest option with a small initial cost. However, over time, the cost of running them becomes expensive. Nevertheless, they are an ideal choice for people who don’t need to heat the pool water frequently.
How to Pick the Right Pool Heater
To ensure you have the ideal pool heater, the factors discussed below should be considered:
Before anything, determine the surface area of your pool or find out its water holding capacity. This info will help you get the right swimming pool heater to offer enough heat. The heater power is always rated in British Thermal Units, BTUs. You can find a list of heater and power ratings to guide you online.
If you love to have your pool water heated within a couple of minutes, then you should lean more towards a high power electric heater. On the other hand, if rapid heating isn’t on the top of your priority, then a solar pool heater is the way to go. Moreover, it’ll help save more money on the monthly energy bills.
For this equipment, there’s two cost attached – an initial cost and a monthly bill. In most cases, you have to compromise one for the other when making a decision. A gas heater is the most affordable option, and the solar pool heater comes with very high price tags.
Keep in mind the cost of installing these units. However, in terms of monthly bills, solar option is cost-free but electric, and gas heater always comes with monthly bills which depends on how frequent you heat the pool.
Shape and Size of Pool
The shape and size of your pool can influence your decision on the type and power of the heater to splurge on. Needless to say, pools with large capacity and complex shape will require a heat with high power rating and vice versa.
Heaters for Above Ground Vs. Inground Pools
The best heater for an above ground pool might not be the right pick for an in-ground pool. For example. Solar heaters are not suitable for an in-ground pool since they offer low power. On the other side, a powerful electric heater is known for its high power, which will be absolutely perfect for large above-ground and in-ground pools.
As discussed above, some pool heater models rely on sunlight or the ambient temperature of the surroundings to increase the temperature of your pool water. Therefore, the climatic condition is an essential factor to put into consideration when choosing a unit. When determining the power needed to heat your pool, the climate plays an integral part of that energy requirement.
Casing of the Heater
Spa/pool heaters are likely to fail sooner than later as a result of galvanic corrosion. Therefore, some model comes with attached bonding wire to the heater casing reducing the effects of corrosion, which ultimately leads to the premature failure of the heater.
A professional electrician installs the bonding wire to the casing lug, and the other end is connected to the mains for power. In another scenario, a ground installation may be performed through a grounding plate close to your pool equipment.
Either you have an above ground or in-ground pool, a heater helps extend your swimming season and get more value during cold weather. But this post has included the top 5 best pool heaters and a buying guide to ensure you make the right choice.
