Proper handling and maintenance of Australian spa parts hold a high degree of importance in making sure that your hot tub spa will remain in tip-top shape. There are several spa parts that you might need to keep your eyes on so that they will remain in their best working form. This includes the manifold assemblies, pc boards, top-side controls, heater element, blowers, and pressure switches. Depending on the issue at hand, they can be replaced instead with a new one if the item is beyond repair already.
The hot tub heater element of your swim spa and the electric immersion elements that are usually found in household hot water heaters for household use share something in common, but they are also distinct in some ways. It is second nature to hot tub water chemistry to vary, and this is usually most demonstrable when, say, at least 3 or 4 people hop in on the tub almost at the same time.
Besides, swim spa heater elements are susceptible to some issues. This would vary from having air right inside the heater chamber to low water flow. These variables are among the top and leading contributing factors to have a reduced life span for your swim or hot tub spa heater.
Air Pockets and Air Bubbles
With the exclusion of low water flow, the main concerning issue that spa heater elements are likely to have is air pockets and air bubbles. The presence of these two can significantly work to the disadvantage of your heating element and thus reduce its expected service life.
The air that comes in direct contact with the heating element paves the way for the outer sheath to heat up unevenly in no time. When this happens, it will likely break the protective sheath, exposing the filament in the process.
You mount the low flow heaters vertically. Doing so will allow the bubbles to exit the chamber without running the risk of being entrapped. Tube heaters that are similar in structure to the Laing design are not likely going to trap bubbles. It allows them to get bent and take on bizarre shapes. You can even lay some of them on the floor.
The manner in which swim spa pumps are designed will allow them to get flooded. They are not supposed to leak air or to cavitate with the drawing in of air. If that happens, the air will be sent through the heating element of your hot tub. Ozone injectors are supposed to be installed just before the heater. This would work against the heater element lifespan and creates some unnecessary confusion also to the heater sensors of a hot tub.
Low Flow Heaters
The low flow heaters are intended for vertical mount operation. These heaters and elements are designed to work on flows that are greater than 9+ GPM. It explains the reason why low flow heaters are usually partnered with low flow circulation pumps such as Laing and Grundfos and Waterway. And it’s all because they come with a minimum of 9+ GPM plus the bonus of spa ozone injector.
The reason why low flow heaters are far more expensive than others is the fact that they require more material and labor.
Some repair technicians themselves are not even aware of this, they don’t know either. It is also possible that some would try to save money and think that they can do so by putting a high flow heater into a low flow system of circulation plumbing.
This may work for some time but not for long. After which the element would come burned out, along with the accompanying piping, wires, and plastic parts. Therefore, you must ensure you are dealing with the correct and intended heater for your outdoor swim spa.
Your hot tub swim spa may be the best gift you have given yourself so far, but understanding exactly how to maintain Australian spa parts is the gift you can give to your hot tub. By observing the above measures, you will get the most value from your outdoor water entertainment feature, particularly their heating element, even to the point of prolonging their expected service life.
