How Do Pool Heaters Work?

 In Pool Heating, Pool Relaxation

Few things compare to jumping into a refreshing cool pool on a scorching hot summer’s day. But there is such a thing as too cold. Pool water doesn’t have to be ice cold to feel refreshing. While pool heaters don’t turn your pool into a jacuzzi, they can still provide some warmth to make the pool a fun and comfortable place to hang out during chillier summer afternoons.

A pool heater takes water from the pool and takes it to a heating tank that sends warmer water back into the pool. This is an exchange of cold and warm water that keeps your pool at a comfortable temperature, even if it is cold outside. There are some key things to know if you are new to pool heaters.

Pool Heaters are Perfect for Year-Round Pool Use

Some might think that you only need a pool heater if you live in colder states like Maine or New York, but that is not the case. But a pool heater can keep your pool water at a steady temperature, especially if you use it year-round in states like Florida or California. For states that do experience a little cold but nothing as drastic as blizzards, a pool heater lets you stretch out pool season for a few more months.

Two Kinds of Pool Heaters: Electric Heaters and Gas Heaters

There are two types of pool heaters available: electric and gas. Both operate in different ways and work well different pool owners.

Electric Heater (Heat Pump)

The first kind of pool heater is the electric pool heater, otherwise known as the heat pump. The more eco-friendly of the two, a heat pump uses a fan to suck air from outside your pool. The pump then uses this sun-warmed air and circulates it through an air evaporator coil. Then that air turns into a warm gas that compresses into even hotter gas that warms up cold water from the pool. The water comes in cold and goes out warm. These heat pumps only work efficiently if the temperature out remains above 45-50 degrees Fahrenheit.

Heat pumps are ideal for homeowners living in warmer climates and use their pools often. This is because the heater uses the outside temperature to work and it is more environmentally friendly than a gas heater. If you use your pool frequently, an electric heater is more reliable and the cost is a lot lower to operate. A low operation cost allows you to use your pool heater more without spending a ton. A heat pump is less expensive than a gas heater since it relies on air and the flow of gas. However, this type of heater is slower than a gas heater and also is not great for colder climates.

Gas Heater

Gas heaters rely on natural gas or propane. As the pump circulates water, the water passes through a filter to get to the heater. In the heater, gas burns and generates heat to transfer to the water. Then the water is sent back into the pool.

Gas heaters heat pool water rapidly and are great for homeowners who use their pool infrequently. These heaters work faster because natural gas and propane burns fast. They are also a lower cost upfront usually around $1,500. Gas heaters are not the most energy-efficient option since they emit carbon dioxide. Green heaters like an electric heater might be the better option if you don’t like the idea of carbon dioxide being in your pool. Going eco-friendly is great for your health and for the health of your environment. Gas heaters also do not last as long as electric heaters as they have an average lifespan of five years.

What is the Best Heater for a Swimming Pool?

If you use your pool infrequently and live in a colder climate, a gas heater is probably your best bet. On the contrary, if you live in a place with warm weather and go for swims often, an electrical or pump heater will suit your luxury pool best.
