Spas with three pumps offer a luxurious experience, providing a range of massage options and power levels for ultimate relaxation. However, the heating constraints associated with these spas require understanding to ensure optimal performance and comfort. Let’s delve into what makes heating a spa with three pumps unique and how to navigate it effectively.
What Spas Have Three Pumps?
Spas equipped with three pumps typically include models such as A9L, M9, and M8.
When Does the Heater Run?
In most cases, the heater will operate whenever necessary to maintain the desired temperature of the spa water. However, there’s an exception to this rule: when all three jet pumps are running at high speed simultaneously. During this scenario, the heater will temporarily shut off. This design choice prioritizes delivering a powerful massage experience over heating the water while the spa is in use.
| Pump 1 | Pump 2 | Pump 3 | Heater Status |
|---|---|---|---|
| High | High | High | Off |
| High | High | Low | On |
| High | Low | Low | On |
| Low | Low | Off | On |
| Low | Off | Off | On |
| Off | Off | Off | On |
Why Won’t the Heater Run When All Three Pumps Are Running?
The primary reason the heater doesn’t operate when all three pumps are running on high is due to electrical constraints. Simply put, there isn’t enough available amperage to power all three pumps and the heater simultaneously. This trade-off ensures that users can enjoy a robust massage experience without compromising the integrity of the electrical system.
What to Expect When Using Your Spa in the Winter Months
During most months of the year, the spa will retain its heat effectively while in use. However, in colder months, users may notice a slight cooling effect, particularly if all three pumps are running at high speed. To mitigate this, it’s advisable to limit usage to two pumps on high while keeping the third pump at a lower speed. This strategy helps maintain water temperature even in extreme cold conditions.
Tips to Keep Your Spa Warm
- Set to “Standard Beginning”: Ensure your spa is set to this mode to maintain a consistent temperature, keeping it hot and ready for use at any time.
- Program Filter/Heating Cycles: Schedule filter and heating cycles to coincide with your typical spa usage times. This ensures that the water is adequately heated just before you plan to indulge in a relaxing soak.
Can I Make My Spa Heat Faster?
While not always necessary, some users may desire faster heating times, especially in colder climates. Upgrading the spa’s heater is an option worth considering. Aftermarket options are available, with prices varying depending on the model and specifications. Generally, upgrading from a standard 4.4kw heater to a more powerful 5.5kw heater can be achieved for a reasonable investment, typically costing a few hundred dollars.
It’s important to note that if all three pumps are running at high speed and you wish to activate the heater, adjusting one of the pumps to a lower speed may cause a delay before the heater kicks back on. This delay is normal and is part of the system’s operation to ensure safe and efficient heating.
Understanding the heating constraints of spas with three pumps enables users to optimize their spa experience while maintaining energy efficiency and safety. By following these guidelines and implementing appropriate strategies, you can enjoy the ultimate relaxation and comfort your spa provides, regardless of the season.
