The right size of pool heat pump will be beneficial in many ways by keeping the runtime to the optimum level, reducing the energy (electricity or fuel) used to heat the water, and generally knowing when the pool would have been heated enough for a swim in your weather of choice.<\/p>\n\n\n\n

In this guide, we look at the typical pool heat pump sizing parameters such as the factors determining the size, the rules to choosing the size, and how to calculate the sizing of the pool. These aspects should always be put into consideration to save on time and money on your end.<\/p>\n\n\n\n

Guide: Factors that will Determine Size and how<\/h2>\n\n\n\n

The factors that will determine the size of the swimming pool heat pump include the following:<\/p>\n\n\n\n

1.     The size of the pool<\/h3>\n\n\n\n

A larger pool will definitely need a larger pool heat pump to bring the water to a certain temperature within a given time. If you get one that\u2019s too small, it’ll take ages to heat the water. At times, you may never get the water to heat up as the heat lost to the environment can be equal to or more than the heat from the pool heat pump.<\/p>\n\n\n\n

2.     Ambient temperatures<\/h3>\n\n\n\n

To heat the pool water to a certain temperature within the same period of time, you’ll need a bigger pool heat pump in the winter than in the same. This is because you’ll need to capture more heat from the environment than in the summer.<\/p>\n\n\n\n

3.     Type of pool<\/h3>\n\n\n\n

The type of pool in terms of whether it\u2019s in the ground or above ground also determines the size of the pool heat pump. For those swimming pools that are built into the ground, raising their temperatures and keeping them at a certain level is easier as the ground adds to the heat retention level of the water.<\/p>\n\n\n\n

Pools above the ground tend to lose heat to the environment faster than those in the ground as they have larger area exposed to the air outside.<\/p>\n\n\n\n

4.     Desired temperature rise<\/h3>\n\n\n\n

How much you need the temperature of the water to rise is also a major factor. Basically, if you need a bigger rise, you\u2019ll need a bigger pool heat pump as it\u2019ll raise the water temperature faster per unit time than a smaller one.<\/p>\n\n\n\n

5.     Pool coverage<\/h3>\n\n\n\n

If you cover the pool, it\u2019ll retain heat for longer than if you didn\u2019t. As such, you\u2019ll need a smaller pool heat pump to raise the temperature of the pool to a certain level if you cover it.<\/p>\n\n\n\n

These factors should always be considered before deciding on the type and size of pool heat pump for your pool.<\/p>\n\n\n\n
