Efficiency is the key when looking at heating options for your pool or spa.
Everything you choose will heat your pool, sure, but will it do it in a way that saves money and energy? There are a lot of options, including solarheating.
Here's some things to think about when it comes to your pool, and suggested options for heating: Volume This includes the size, shape and depth levels of your pool.
Volume is expressed as a cubic area.
This is the basic measurement for all your pool needs, and it also dictates what size heating you'll need.
If you've got a spa feature with your pool, the spa area size is the area for calculation.
Pool sizes map out the requirements for heaters.
Big pools naturally require more power, despite the fact that pool heat pumps are very economic.
The requirement for more power isn't necessarily a problem.
Solar powered heating systems are very efficient, and over time they're a cheap option for heating big pools.
Climate Climate does play a role in pool heating requirements.
In cooler climates, the demand for power for heating naturally increases, because heat loss rates from the water are higher.
This can be countered to some extent by a good pool cover, which reduces the rate of heat loss, and helps create a micro climate in the pool area.
Depending on your local climate, you may want to take advantage of the different options provided by electric, gas and solar systems.
Some people use "hybrid"heating options.
For example, a combination of a pool pump and a solar system is a possible solution, combining the efficiency of the heat pump with the economics of the solar power supply.
Usage.
Your pool usage is definitely a major consideration in making decisions about a heater:

• Athletes and people in training: If you do water training, a pool heater is an essential.
  It's the perfect environment for this type of training, and it's also very good for tired muscles.
  
• The familyenvironment: This environment is also a good reason for getting a heater.
  Anyone who's jumped into a really cold pool won't need to be told that it's not the best thing for kids in particular.
  
• Older people: A heated pool is the perfect pick me up if you're feeling the cold.
  Heated pools are common features in many aged care facilities with good reason.
  They provide valuable health benefits, as well as a high degree of comfort.
  

Ideal temperature The ideal temperature is a personal preference, but for best effects, studies have established that 28-30C is the optimum.
This is a pleasant level of heat, and it's also the recommended level for water training and therapeutic purposes.
These temperatures are also the usual design standard, so your pool won't have any trouble maintaining the temperature as you like it.
The only real issue is persuading yourself to get out of the pool.
