How do above-ground pool heaters work?

swimming pool heater

The pool heater is so fascinating that you can use it to warm up your pool. You might be wondering how this appliance operates. In this article, I’ll be showing you how it works in addition to answering any other questions you might have surrounding pool heaters.

Pool heater mechanism of action

The pool heater is attached to the pool pump. When water passes through the pump and filter, it crosses the heater. An evaporator coil with refrigerant is located within the heater.

The heater has a fan that draws in air from outside and directs it over this coil. The refrigerant is a liquid, which then absorbs heat from the air that is blown over the coil. This causes the liquid to transform into a gas. Then it passes into the compressor. The work of the compressor is to increase the temperature of this gas and then pass it into the condenser.

The condenser transmits heat from this hot gas to the circulating pool water, which has a lower temperature. This water then returns to the pool. As more water comes in contact with the condenser, the overall temperature of the pool increases.

The hot gas, after losing heat, transforms back to liquid and goes back to the evaporator, where this cycle repeats itself.

What is the fastest way to heat an above-ground pool?

Using a gas-powered heater

Using a gas-powered heater is one of the fastest ways to heat an above-ground pool. It makes use of propane and can cause your pool’s temperature to rise by up to 30 degrees Fahrenheit. The heater is installed by the poolside, and it draws in water, heats it up, and then sends it back to the pool.

Gas-powered heaters are a worthy investment. Though they might be a bit expensive, they are the most effective ways to heat up your pool.

What is the cheapest way to heat a swimming pool?

Solar blankets

Using solar blankets is a way to save money while still achieving the goal of heating your pool. Solar blankets require less maintenance but can still do the job of heating your pool.

The mechanism of action is centered around preventing evaporation from the pool’s surface. Evaporation is how pools lose a large percentage of their heat and chemicals. Hence, investing in solar blankets can save you money and time.

In addition, solar blankets can prevent the accumulation of debris in your pool and the formation of algae.

What are other ways of heating your swimming pool?

There are some other methods you can use to heat your pool. I will list them below.

Solar rings.

Solar rings are super easy to install. They are quite cheap, not stupid solar blankets, and using heat from the sun, they can warm your pool without any additional effort. They are small magnetic rings that you can place side by side to cover your pool’s surface. So this saves you from the hassle of cutting a large sheet, like in the case of blankets.

Heat pumps.

Heat pumps are another option you can look at if you’re looking to save energy costs. It simply works by redirecting warm air from a nearby location to heat up your pool water. They are different from heaters in the sense that you don’t need gas or any other energy source to power them. You just need a source of warm air, such as if you live in a warm region.

Solar heater

Solar heaters are a nature-friendly option. They are also powerful to boot. They have the capability of raising your pool‘s temperature by over 20 °F. They are dollar-driven and transform energy from the sun to heat your pool.

What you need is the installation of solar panels. Hence, the initial cost might be expensive, but in the long run, it’s quite cost-efficient and environmentally friendly.

Liquid blankets

Liquid blankets are a type of solar pool cover that creates an invisible barrier over your pool. It works to prevent excess evaporation from your pool. It is more aesthetically pleasing and is still overall safe for swimmers.

How can I heat my pool naturally?

Solar covers.

Solar covers prevent heat loss from your pool by hindering evaporation. It creates a barrier that prevents water loss when the sun heats the water. Also, it has air pockets that can trap heat from the sun and help to heat up the water.

Solar covers can raise the temperature of your pool water by 12°F.

Solar rings.

Solar rings have a similar function to solar covers. They are easier to use. They are smaller sets of rings that are 5 feet in diameter. When they are grouped together, they can act as a solar cover. They prevent evaporation of your pool’s water while transferring heat from the sun into it.

Coiled black hose

You can use a black garden hose to heat up the pool. All you need to do is place the holes near a place that receives sunlight. Then connect one end of the hose to a pump, preferably your pool’s pump. When the pump pulls out water from the pool into the hose, it gets heated on its way through the hose. When it returns to the pool, the pool’s temperature increases.

Solar mats

Slomin’s use the same mechanism of action as the black hose. However, in this case, the mat contains a series of tubes. The mat is placed in a place where it is exposed to heat from the sun. It’s also connected in the same way to the pool’s pump. The water gets warmed on its cycle back to the pool.

Use a wood-fired pool heater.

You can get creative by using a wood-fired pool heater. All you need is a fire pit. Then get a copper pipe and a small pump. Start the fire and then run the copper pipe across the fire. Connect one end to a garden hose and the other end to a pipe connected to your pool. Start the pump, and as the water from the pool enters the copper pipe, it gets heated and then circulates back into the pool through the water hose.

Is there a difference between in-ground and above-ground pool heaters?

Pool heaters are rated in BTUs. It refers to the amount of heat required to raise one pound of water by one degree.

In general, since in-ground pools have more water, their heaters will need to have a higher BTU rating.

How many hours a day should a pool heater run?

It is recommended that during the summer you run your pump for 10 to 12 hours straight with a full stop, while you’re on it for six to eight hours during the winter.

The reasoning behind this is that algae tends to grow more in the warmer months. Leaving the pump on will help to filter out more algae.

How do you stay warm in a chlorine pool?

If you want to stay warm in your pool, you can use the following tips:

Wear rash guards and wetsuits.

Rash guards and wetsuits are usually preferred in colder waters. However, this does not stop you from using them in your own pool. These costumes help to retain your body heat. You can also use swimming caps to prevent heat loss from your hair.

Do some warm-ups.

Warm-ups are recommended before you begin swimming. The goal is to raise your body temperature so that when you step into the pool, it won’t feel as cold.

You can also do some light treading and splashing in the pool to quickly acclimate to the temperature.

Eat Food.

There are certain foods that you eat that will help me move your body. Your body’s metabolic rate increases when trying to digest these foods. Foods such as beef and poultry can have great effects on raising your body temperature. This is because they take longer to digest. Also, eating healthy fats such as those from nuts and avocados can be useful in warming your body. Spicy foods containing chili can also work.

In-Pool Heating

Installing a water heater is a go-to option. Even when the weather is colder, they can keep the pool warm for extended periods of time.

Does heating a pool reduce chlorine?

Yes, it does. Higher temperatures affect how long chlorine stays in a pool. When your pool is heated, it quickens the breakdown of chlorine and hence shortens its half-life.

This can lead to the proliferation of bacteria and algae. Sciencing.com says that for every 10 degree increase above 80 degrees Fahrenheit, twice as much chlorine is required to keep the free chlorine at the appropriate levels.

On an average sunny day, 95% of the pool’s chlorine can be lost in under 4 hours due to increased breakdown and evaporation.
