Electronic parts for Calspas spas 

The spa heater is an essential component of any spa system. As the name implies, it is a device used to heat the spa water. The heater is usually installed inside the spa cabinet and is connected to the circulation pump. The heater is one of the main elements that contribute to making the water in your spa pleasant and comfortable.

The role of the heater is to maintain a constant and comfortable water temperature. Most spas have an average operating temperature of about 38°C. The spa heater is equipped with a thermostat that allows you to regulate the water temperature according to your preferences.

In general, the spa heater works by using an electric resistance. As the water flows through the heater, it is heated by this resistance. Heaters are usually sized to match the size of the spa and are designed to be very efficient.

It is important to note that the heater is also a key element in the filtration and treatment of your spa water. Warm water is more effective at dissolving water treatment chemicals and improving water quality. In addition, hot water helps prevent the growth of bacteria and germs in your spa water.

Overall, the spa heater is a crucial component for any spa owner. It goes a long way to keeping your spa water at a comfortable and consistent temperature, and also helps with filtration and water treatment.
