One of the most relaxing features of a spa is its warm water. Warm water isn't just calming, but it can also help relieve physical discomfort. When the water in your spa isn't warming properly, this is cause for concern. Fortunately, there is generally a solvable problem that can be addressed to ensure warm water is returned to your spa. Here are just some of the reasons your spa's heater isn't functioning correctly.
A common cause for a heating issue is a thermostat error. When you adjust the temperature for the water in your spa, it's the thermostat's job to determine when this temperature has actually been reached. However, when the thermostat is not properly gauging the temperature, this doesn't happen.
The heating element might turn off before the correct temperature is reached. In some cases, the thermostat can simply be calibrated, but in other cases, it needs to be replaced.
Poor Water Balance
When the average person thinks about proper water balance, or pH, they think about health. Water that is off balance can harbor bacteria, cause skin irritation and a host of other issues for your health. However, this isn't where the issues stop. Unbalanced water can cause mechanical issues with the heating element as well.
Water in this condition also often contains a higher level of minerals. These minerals often settle on your heating element. Once this happens, this lowers the efficiency at which the heating element is able to work, and the result is reduced heat production. Over time, this can cause permanent damage to the heating element. Maintain proper water balance to avoid this.
Most heating elements need to be submerged in water to operate correctly. When they are not covered with a sufficient amount of water, they can burn out and fail. If you are having heating issues, it could be that water flow within the heating element area is too low.
The heating element's built-in pressure switch is responsible for monitoring flow rates. When the water flow level goes under the threshold, this causes the heating element to shut down and go in protection mode, leading to your heating concerns. The most common reason for reduced flow is a dirty filter.
If you can't understand why your spa isn't producing heat properly, it's time to contact a technician for service. Get in touch with a company like Anchor Pools & Spas for more information.
