Criteria for Choosing the Best Pool Heaters
Pool heater with a higher BTU (British thermal unit) rating, will effectively and quickly raise the pool temperature in a fraction of the time it takes those with a lower rating. Consequently, the user should take into consideration the size of their pool before committing their money. While high-performance pool heaters are patently more expensive, they’ll spare the user the frustration of waiting endlessly for the temperature of the pool to rise to comfortable and accommodating levels before dipping in. Of course, a higher BTU rating also translates to more energy consumption but it’s a worthy trade-off if you really want to extend the swimming season. While we’re on the performance, keep in mind that gas-powered models are more efficient and fast in heating water, followed by electric models and lastly solar pool heaters.
On a similar note, it’s important that you familiarize yourself with the type of pool you have. Is it above ground or in-ground pool? The two have different water holding capacities and hence come with heating requirements.
Shape, Size, and Capacity of the Pool
Closely related to the performance factor discussed above is the physical attributes of the pool. Large pools obviously carry a lot more water than their smaller counterparts. To effectively heat a large pool holding lots of water, you’re going to need a powerful heater packing lots of BTUs. The aim is to cut the time and effort it takes to reach the desired temperature. There are sorts of pool heaters on the market suitable for large, medium and small-sized pools. Take this into consideration before buying to avoid wasting your money on an overperforming or underperforming unit.
It beats the point buying an expensive pool heater with a cluttered control panel, if at all it has one, that’s difficult to use. A pool heater needs to take the time, effort, and frustration away from warming the pool; it should be as easy to use as possible. To this end, pay attention to the convenience features it packs. Is the control panel within easy reach? Is it cluttered with several confusing buttons or not? The design of the pool heater should provide the user with an easy way of changing the temperature settings and viewing the temperature readouts. Similarly, it should be able to operate quietly to not interfere with the peaceful and quiet pool environment. While they are considerably more powerful, gas-powered are notorious for producing a lot more noise than their electric and solar-powered counterparts.
The constant exposure of pool heaters to water increases their susceptibility to rust and corrosion, especially if you install them in salty waters. To guide against corrosion and rust affecting the delicate internal components like the heater, the pump, and filter, ensure your unit is high-quality construction using durable and rust and corrosion-resistant materials, so they provide you with several years of trouble-free and smooth heating experience.
On another note, the installation process is usually a smooth and straightforward one, at least for the vast majority of pool heaters. To make it simpler, manufacturers endeavour to make lightweight and compact designs that are compatible with most equipment pads. During installation, make a point of leaving sufficient room for manoeuvrability and services, if and when it is due. For electrical models, the installation can be a little complex, and it might be difficult, especially for greenhorns, to get all the corrections right. To ensure the machine works efficiently and smoothly, it is advised that you have the brand do the installation or that you seek professional assistance.
Frequently Asked Questions

A: Unless one quantifies, in terms of decibels, the noise a pool heater produces, it’s difficult gauging how noisy they are. As a general rule, though, gas-powered models are considerably noisier than their electric and solar-powered models. It all comes down to the number of moving parts the machine packs. Models with components like fans, blowers, and fans motors will generate more noise than those that don’t.
