Quick Overview

Pools and spas that use salt water chlorine generators as their sanitizing system need a heater that offers increased corrosion resistance. Coates TR heaters are designed specifically for use in pools and spas with a maximum salt concentration of 3,500ppm.

Nothing says summer like your first dive into the pool. But in the early days of the summer season, the water in your pool may be too chilly for you and your family to enjoy. Adding a heater is a wonderful way to make swimmers more comfortable, and extend the outdoors season.

If you're considering a new heater for your saltwater pool or spa, it is essential that you choose a model that has been designed to withstand the corrosion of high-saline water. Saltwater pools, though they are more comfortable for human skin, can be extremely corrosive and damaging to traditional pool heaters.

Why choose the Coates Saltwater Pool and Spa Heater?

If you have a saltwater pool or spa, or if you've considered making the change in future, it is important to note that the change in water chemistry can have a big impact on your pool equipment. Salt water is much more corrosive to pool equipment than "œfresh" water, and many pool owners have been disappointed to find that their new salt generators have destroyed their pool heaters.

The new Coates Electric Heater has been designed specifically for pools and spas that are treated with salt - tough enough to withstand corrosion without compromising on performance. This Coates heater also has built-in protection for your heater. A flow detector ensures your heater will turn off if flow is too low, and a temperature sensor ensures that your heater will shutdown automatically if the temperature gets too high.

The Coates Electric heater is as easy to use as their traditional models. A digital display gives you full control over the operation of your heater, and the temperature of your pool. You can set your heater to maintain your preferred temperature, or crank up the dial to warm things up on a cool day.

Reliable Heating for Saltwater Spas and Pools

A new heater for your pool or spa is a big investment, and one that you should make wisely. If you have a saltwater pool or spa, or if you've considered making the switch, it is essential that you choose a heater that can withstand the harsh salinity without succumbing to corrosion. With the new Coates Electric heater, saltwater swimmers can rely on many seasons of reliable heating performance, without worries about corrosion or damage.
