Types of Ice Bath Water Pumps (Inline vs Submersible)
When it comes to choosing a water pump for your cold plunge tub, you’ve got two main options: submersible pumps and inline pumps. Both types get the job done, but they work in different ways and have their own unique pros and cons.
Submersible Pumps
Submersible pumps are designed to be fully submerged in your cold plunge tub. They suck up the water directly from the tub and push it through the chiller system to cool it down before sending it back into the tub. This creates a continuous loop that keeps the water circulating and maintains a consistent temperature. These pumps are usually pretty compact and have a sealed motor that allows them to work underwater without any issues.
One of the biggest advantages of submersible pumps is how easy they are to install. You don’t need any fancy plumbing or mounting systems – just drop the pump in the tub, hook up the hoses, and plug it in. They also save space since they sit right in the tub, and they tend to be quieter since the water muffles the sound of the motor. Plus, they’re really efficient at cooling the water because they pull it directly from the tub without any heat loss during transport.
However, there are some downsides to consider. The main concern with submersible pumps is the potential safety risk of having an electrical device in the water. If something goes wrong, it could be dangerous.
To mitigate this risk, it’s crucial that you unplug the pump prior to entering the cold plunge tub.
It’s also important that the pump is properly grounded. Always plug the pump into a GFCI (Ground Fault Circuit Interrupter) outlet, which will instantly cut off the power if there’s any malfunction or short circuit.
Submersible pumps may not last as long as inline pumps since they’re constantly submerged in cold water, and they can be trickier to repair or maintain since you have to take them out of the water and dry them off first.
Pros
- Easy to install
- Space-saving design
- Quiet operation
- Efficient cooling
Cons
- Potential safety hazards
- Risk of leaks
- Shorter lifespan
- More difficult to maintain and repair
Inline Pumps
Inline pumps, on the other hand, are installed outside of the cold plunge tub, usually somewhere between the tub and the chiller unit. They work by pulling water from the tub through an inlet hose, pushing it through the chiller to cool it down, and then sending it back to the tub through an outlet hose. The pump itself isn’t submerged in water – it has its own separate motor housing that connects to the plumbing system.
The biggest benefit of inline pumps is that they’re much safer since they’re not in the water. You don’t have to worry about electrical hazards or leaks. They’re also easier to maintain and repair since you can easily disconnect them from the plumbing without having to fish them out of the tub. Inline pumps generally last longer than submersible pumps since they’re not constantly exposed to cold water, and they offer more flexibility in terms of where you can install them around your tub setup.
However, inline pumps do have some drawbacks. They take up more space than submersible pumps since they’re installed outside the tub, so you’ll need to have room for the pump and all the plumbing connections. They can also be a bit noisier and cause more vibration since they’re not submerged, although you can minimize this by using vibration-dampening mounts and securing the pump properly. Inline pumps may be slightly less efficient at cooling since there’s a small amount of heat loss as the water travels through the hoses.
Pros
- Safer operation
- Easier to maintain and repair
- Longer lifespan
- More placement options
Cons
- Requires more space
- Potentially noisier and more vibration
- Slightly less efficient cooling
- Must be primed before use
Factors to Consider When Choosing a Water Pump
When you’re shopping for a water pump for your cold plunge tub, there are a few key factors to keep in mind to ensure you get the best setup for your needs.
Size of the Cold Plunge Tub and Required Flow Rate
First off, consider the size of your cold plunge tub and the flow rate requirements of your water chiller. A larger tub is going to require a pump with a higher flow rate to keep the water circulating properly and maintain a consistent temperature throughout. Your pump should be able to deliver enough flow to match the chiller’s capacity, but be careful not to go overboard. If you get a pump that’s too powerful for your chiller, it could put a lot of strain on the unit and reduce its efficiency or even shorten its lifespan.
For nearly all home cold plunge tubs and water chillers, a pump with a flow rate of 1200 gallons per hour (GPH) should work well. This flow rate range is suitable for the majority of setups and will ensure that your water is circulating effectively without putting too much stress on your chiller or pump.
However if you want to better match your tub size to your pump, consider the following table.
| Gallons | GPH |
| 60 | 500 |
| 85 | 700 |
| 110 | 950 |
| 150 | 1200 |
| 225 | 1800 |
Energy Efficiency
Energy efficiency is another important factor to consider. Pumps with higher energy efficiency ratings can save you money on your electricity bills in the long run and are better for the environment. So, if you’re looking to minimize your operating costs and reduce your carbon footprint, keep an eye out for pumps with good efficiency ratings.
Noise Level
Noise level is also worth thinking about, especially if your cold plunge tub is located near living spaces or in a quiet area. Submersible pumps are generally quieter than inline pumps since the water helps muffle the sound of the motor, but noise levels can still vary between different models. If noise is a big concern for you, do some research to find a pump that operates quietly.
Durability and Material Quality
When you’re investing in a water pump, you want to make sure it’s built to last. Look for pumps made from high-quality, durable materials that can withstand the constant exposure to cold water and the wear and tear of regular use. Pumps with corrosion-resistant components, such as stainless steel or thermoplastics, are a good choice for cold plunge tub applications.
Budget
Finally, don’t forget to factor in your budget. While it’s tempting to go for the cheapest option, investing in a high-quality pump can pay off in the long run. Look for a pump that balances cost with performance and reliability. A well-made pump might cost a bit more upfront, but it could save you money on maintenance and replacement costs down the line.
Compatibility with Your Setup
Finally, make sure the pump you choose is compatible with your specific cold plunge tub and chiller setup. Consider factors like the size and shape of your tub, the location of your plumbing connections, and the specifications of your chiller. Some pumps may require additional fittings or adapters to work with your setup, so it’s important to do your research and make sure everything will work together seamlessly.
