There are times, mostly during the winter season, when you want to swim but the pool water is too cold for you. In fact, average pool water temperature which typically ranges from 78oF to 82oF, might be too cold for young children, elderly, and some certain individuals.
But there is a solution to this problem – pool heating. This involves the use of various technologies to warm your swimming pool water. Understanding how to heat your swimming pool is vital if you are to get maximum enjoyment out of it, whether it is an indoor or outdoor pool.
In this article, we will explore 5 effective methods of how to heat a pool and factors that you should consider before choosing any of the options.
Here are the most effective methods or technologies of how to heat a swimming pool and derive a desired water temperature.
A swimming pool heat pump is the most efficient and eco-friendly method of how to heat a pool. This is because it doesn’t generate heat, instead, it uses a small amount of energy to extract heat from the surrounding air and transfers it to the pool water.
Pool heat pumps guarantee a constant pool water temperature no matter the weather condition since they depend on temperature not sunlight. To save energy consumption, there are more advanced inverter pool heat pumps that have the ability to lower their working speed when the water temperature has gotten close to the desired temperature.
Based on their heat source, commercial pool heat pumps can be classified into air-source and ground-source pool heat pumps. Air-source heat pumps extract heat from the outdoor air while ground-source or geothermal heat pumps extract heat from the earth (below the ground).
Heat pumps can be used for both heating and cooling purpose
They yield better energy savings
Low operating costs
Low environmental impact
These systems are extremely quiet
High upfront cost
Takes longer time to heat the pool
Depends largely on the temperature of the surrounding
An electric pool heater (also known as electric resistance heater) uses electrical current to warm pool water. It operates by passing water over a heated coil or element. The water absorbs heat as it flows over the heated surface and circulates the heat back to the pool, raising the overall temperature.
Since it depends solely on electricity, electric pool heaters can deliver consistent heating performance regardless of the weather or outdoor temperature. This makes it a dependable option during very cold climates and it is best suited for people that require fast & occasional heating of their pools.
Provides rapid heating of pool water
They are compact and easy to install
Guarantees year-round heating
Less efficient and consumes a lot of energy
Requires high operational cost so they are not ideal for frequent use
Produces large environmental footprint
A solar pool heater is another technology that can solve the problem of how to heat above ground swimming pool. It is made up of a solar collector which extracts heat from the sun and transfers it to the pool water. The collector consists of black tubes or panels that are arranged in series and placed on your roof, veranda, or shed.
This pool heating system provides a sustainable means of heating pool water by using heat from sunlight, ensuring zero carbon footprint. Under steady sunlight, solar pool heat pumps can generate a significant amount of free energy for heating pools throughout the swimming season.
Eco-friendly
Low operating cost
Very durable and requires little maintenance
Heavily dependent on climate condition
High purchase and installation cost
It requires additional space to place the solar collectors
Gas pool heaters make use of natural gas or propane to generate heat and transfer it to pool water. The gas is ignited in a burner where it creates a flame. Heat from the flame is transferred to the combustion chamber that surrounds the heat exchanger. Pool water is circulated through this exchanger and heat is transferred to the water, raising its temperature. Afterward, the heated water returns to the pool and raises the overall pool temperature.
This is the best option if you are looking for how to heat pool quickly so they are mostly used when faster heating and high water temperature are required.
Very effective regardless of climate or air temperature
Provides year-round pool heating
Heats pool water fast
Very expensive to run
Short life span
Noisy operation
Regardless of your chosen pool heating method, pool covers are very necessary for keeping your pool warm. They do this by preventing evaporation which is by far the largest source of energy loss by swimming pools, thereby reducing heating requirements and costs.
Pool covers minimize evaporation from both indoor and outdoor pools. They are made of special materials like UV-stabilized polyrthylene, polypropylene, vinyl, etc and the final product can be opaque or transparent. Pool covers can come in options ranging from manual, semi-automatic, and automatic pool covers, for ease of closure and opening.
Reduced evaporation and increased heat retention
Pool covers prevent leaves, dirt, and other debris from entering the pool
They provide a barrier to prevent accidental falls
High upfront cost
Requires regular maintenance
The covers may not be durable and need frequent replacement
There are a few things you must consider before picking your ideal pool heating method. They include:
Climate: Consider the average weather condition of your area. If the weather is warm, a solar pool heater or heat pump is best advised. But if you stay in a colder region, you should consider getting a gas or electric pool heater. Some modern pool heat pumps are also built to work efficiently in cold climates.
The Pool Size: Larger pools require more energy to heat. Pool heat pumps and solar pool heaters are ideal for large pools, while electric and gas pool heaters are suitable for smaller pools or spas, to save energy.
Cost: Consider the upfront and operation cost of the pool heater. Solar pool heaters and pool heat pumps have high upfront & low operational cost cost, while gas and electric pool heaters cost much more to operate.
Environmental Impact: Pool heat pumps, solar pool heaters, and electric pool heaters leave less negative impact on the environment. But gas pool heaters release harmful substances to the environment.
Energy Saving Ability: Most of the methods of how to heat a swimming pool involves large consumption of energy, be it sunlight, electricity, or natural gas. However, pool.heat pumps are highly energy-efficient, capable of saving up to 80% on energy consumption compared to traditional pool heaters.
Durability: You should also consider the lifespan of the pool heater. Pool heat pumps for example, are generally known for their durability, with a typical lifespan of 10 to 20 years, while gas pool heaters only last between 5 to 10 years.
Heating your pool can be a straightforward process if you choose the right method of how to heat a pool. But before you opt for any of the pool heating methods, you must consider factors like climate, pool size, cost, environmental impact, energy saving, and durability. Among all options, pool heat pumps stand out.
Hurry now and purchase yours from a reputable pool heat pump manufacturer, so you can enjoy a warm and comfortable pool all year long.
