Solar Pool Heater Buying/Buyer’s Guide
Knowing the things to watch out for when selecting your solar pool heater can ensure you choose the right unit for your facility. Let us go through some of these things:
1. Know Your Pool Type

A solar heater can work for both the inground and above ground swimming pools. However, its effectiveness depends on the type of pool you have.
An inground pool requires a big solar heater while an above ground one goes well with a small, stand-alone model. Typically, an inground solar heater should be installed on the roof.
2. Know Your Pool Size
Much like adding a glass of hot water into a cold basin, which can barely change the temperature, small solar pool heaters cannot affect the temperature. Your pool’s size plays a critical role when choosing the perfect heater.
A small pool can do well with a small solar pool heater while a big one requires a big heater.
3. Know the Solar Heat Output
The amount of heat a solar heater can provide is related to its size. Some of the enormous models can increase the temperature by 10 degrees F in 12 hours; smaller units can take even a week.
What you should note is that it is not an instant process, it can take time. You should wait and realize the heating process depends on the availability of the sun.
4. Know the Space You Need

The first thing is to know your pool’s size before you even decide about the space your heater might require. You require a solar pool heater that is half your swimming pool size.
That ratio only works for inground pools. An above ground model might require a smaller heater. What that means is big pools need more space to install a solar heater.
5. Know the Installation Process
Solar pool heaters vary from easy to install to slightly tricky systems. Some units stand freely near the pool when you connect them to the filter pump.
Others require an advanced approach, where you need to build frames to support the pipes and fix them on the roof. The important thing is to ensure you get a model with clear installation instructions.
6. Value for Money
Here you need to choose a heater that can provide years of service – for about 20 years. Also, get a solar heater with a warranty that covers panels, pipes, and other parts.
