5 Significant Parts of Spa Heaters
                                    Five Significant Parts of 
Spa Heaters
Balboa spa heaters are a 
significant aspect of every spa. You 
don’t want to sit in cold weather 
unless it’s 100 degrees outside, 
and that’s not what you want to do 
with your Balboa spa package 
when you purchase it.
If your spa heater is not working correctly, it can leave you 
with a costly frozen mess in the cold winter months. Take a 
look at the post and know how to extend the life of your spa 
heater. 
First, you should understand the essential parts of hot tub heaters. 
1. Heater Assembly 
The heater assembly is available in 
different forms depending on the hot 
tub manufacturer. The commonly 
available assembly is the stainless 
steel tube that contains the heater 
element. The housing exchanges 
heat the heater element produces 
when the water flows through it. The 
assembly integrates with a high-
limit switch and thermostat. 
2. Heater Element 
The heater element is the same as 
its name says. It’s the element that 
produces heat to make your water 
warm. The heater element works 
similarly to a light bulb. After so 
much use, they can burn out. 
Heater elements can be affected by 
corrosion and calcium buildup if you 
don’t maintain hot tub chemicals 
regularly. 
3. Thermostat –
The thermostat comprises a rotating control to set your preferred 
temperature and a capillary tube with a bulb attached to pick up the 
spa water temperature remotely. There is a sensor bulb present in a 
thermo well for ensuring safety. 
If you want to operate the heater properly, the thermostat should be in 
the spa plumbing between the suction point and the heater. It shouldn’t 
be present after the heater.
4. High-Limit Switch –
High-Limit is a safety switch that remains closed until a problem comes 
up with excessive heat. Once the temperature goes beyond the set 
point, it latches on, breaking the circuit. In addition, the safety switch 
prevents the spa heater from melting down when equipment fails. 
You can reset the switch manually by simply pressing the specific 
button when the temperature comes to its normal state. A tripped high 
limit causes a power cut before the fuse and immediately shuts down 
your heat pump and spa heater. 
5. Pressure Switch
A safety switch helps in shutting off the power to the spa heater 
circuit during the interrupted water flow. The switch remains off 
when the system is running normally. However, it will pop open 
if the heat pump stops working. The pressure switch will prevent 
burning up the heater when water is not flowing correctly. 
Extending the Life of Spa Heater 
Do you want to extend the lifetime of your spa heater? If yes, 
you must maintain the proper chemical levels in hot tub 
water. You need to check the pH level of the hot tub water. If 
chemical levels are not balanced properly, they will cause 
scale or calcium buildup and corrosion on your heater 
element. You can buy a titanium element rather than a 
standard element.
