How the Water Heater Works
After the water has gone through the hot tub filter, the water goes to the heater which is the device that heats up the water. The hot tub pump then pushes the water through a heating device where the water is heated based on the desired temperature that was set. In this heating device, there is a heating coil that would convert the energy into heat which warms the water. After the water has gone through the heating device, it then passes through the pipes into the jets. Finally, the Jets deliver the water to the hot tub itself.
Factors to Take Note of When Choosing Spa Heaters
The first factor that you would have to consider is the brand of the heater that you would buy. As much as possible, buy a branded spa or pool heater for your hot tub because you can be assured of its quality. Generic brands may or may not be durable even if you install them in the best hot tubs. Also, not all generic brands have warranties, which means that if it breaks down in the next week or so, you can’t replace it or get it repaired.
Not all heaters are compatible with all hot tubs, and not all heaters can fit the size of the hot tubs. Moreover, not all hot tubs have the specs to take certain heaters. When buying a heater for your hot tub, you need to get the size measurement and the specs of your tub heater before you hit the store.
There are two types of heater that you can choose from: the gas heaters and the electric heaters. The one that you buy will all depend on your own preference. However, it’s best to know the pros and cons of each so that you’ll get an idea of which one is better for you.
Gas heaters are powered by natural gas or even propane. These can usually be found in underground spas (like in Japan), wood hot tubs, or even inflatable hot tubs. Gas heaters can be found outside of the heater cabinet and are connected to the tub system through a gas line wherein the fuel is sent to the heater in order to heat up the water.
The pros would include being cheap to maintain. Natural gas and propane gas are actually both quite affordable, so you won’t have to spend many variable costs maintaining the heater. It also heats up water extremely fast– faster than the electric one. It can heat up water by 1 degree per minute.
As for the cons, the safety risk is present since gas is involved, and you have to be very careful using gas otherwise you might blow away the hot tub by accident. It is also expensive to buy on the spot.
Electric heaters are made of stainless steel tubes that allow energy to enter the tube and heat up the water. As compared to gas heaters, electric heaters, on an overall scale, are cheaper than gas ones from the initial cost to maintenance cost.
The cons would be that it takes a long time to heat up the water. It may even take hours for the electric heater to warm the water. Aside from that, there are also safety issues with electricity. If you are not careful, you may actually electrocute yourself since you’re dealing with both electricity and water.
How to Use and Install the Water Heater
When you replace or install a new tub heater, just follow these steps:
- Turn off the power.
- Drain all the water from the tub.
- Disconnect the power line (the power line is what connects the tub to the heater. If the heater does not have a powerline and is hardwired into the hot tub, disconnect all the wires connecting the heater to the tub).
- Take out old heater (remove all couplings by using a wrench).
- Install a new heater.
- Connect everything back together (couplings, wires, power line, etc.).
After you’ve done all of that, simply test your heater by refilling the tub and try heating up the water. If everything works perfectly fine, then your hot tub is good to go.
