Sta-Rite SR400NA Review

A testament to this is the Max-E’s unique rust-proof exterior. Unlike most pool heaters with metal enclosures, the Sta-Rite SR400NA Max-E 400,000 BTU Pool Heater features an innovative Dura-Glas exterior, making the heater lightweight and rust-resistant. Therefore, not only does it look better than metal units, but it’s more durable as well.

Beyond its durability, the SR400NA also works terrifically. It heats up the largest of pools quickly and efficiently. In fact, it has an industry-leading efficiency rating of 84 percent and is capable of heating the largest of pools by up to two degrees per hour.

Like most of today’s quality pool pumps and heaters, it also comes equipped with a digital LED control panel and display, which serves as the nerve center for this beast of a gas heater. With dual temperature controls, digital temperature readings, and self-diagnostics capabilities, not only does the display add to the heater’s good looks, but it also makes it remarkably simple to operate.

How to Install It

Thanks to its compact and lightweight design, installing the Sta-Rite SR400NA is a breeze. While anyone the least bit handy should have no problem following the manual and performing the install themselves, it’s recommended for an experienced pool company to perform the installation for optimum performance.

How to Use It

As mentioned, it is equipped with a large digital LED display and easy-to-use controls, allowing you to effortlessly monitor and adjust the temperature of your pool’s water.

Owning and Operating the SR400NA

This sleek and diminutive-looking monster of a pool heater can quickly heat the largest of pools. Whether you use natural gas or propane, it’s capable of spitting out 400,000 BTUs of heat and raising the water temperature of a 30,000-gallon pool by two degrees per hour. Simply program your desired water temp, start mixing some margaritas, and sit back while your ice cold pool heats up like Miami in July.

With self-diagnostics, it will even tell you when something needs maintenance. Seriously, having a comfortably warm pool has never been easier.

Final Words

Despite its compact size, the Sta-Rite SR400NA Max-E 400,000 BTU Pool Heater is a powerful heater that works with the best of them. Regardless of your pool size, this remarkable little heater can get the job done and do it efficiently.

With an array of advanced features and an exclusive Dura-Glas exterior, the Sta-Rite SR400NA Max-E is an efficient workhorse that’s easy to install and even easier to use, making it a great option for any pool owner.


If you’re looking for a powerful, efficient, and compact pool heater, than you’ve landed on the right page. Why, you might ask? Well, quite simply, the folks at Sta-Rite designed the SR400NA to outperform every other residential pool and spa heater out there, and many pool owners feel they’ve succeeded.

Hot-Surface Electronic Ignition – With its safe ignition, you never have to worry about the Sta-Rite SR400NA leaking gas or suffering from a blown out pilot light.

Dura-Glas Exterior – Exclusive to Sta-Rite, Dura-Glas is a thermoplastic resin able to withstand harsh weather conditions and the elements.

Cupro Nickel Heat Exchanger – Like other first-class pool heaters, it features a Cupro nickel heat exchanger, which is resistant to corrosion and works great for saltwater pools.

Digital LED Control Panel and Display – In addition to being weatherproof and easy to operate, the digital display is fully programmable and features self-diagnostic indicator lights, making maintenance all the easier.

Low NOx Emissions – It is certified for low NOx emissions, making it environmentally-friendly and a great pool heating option if you live in a state with strict emissions standards, such as California or Texas.

What We Like

Sure, a sparkling pool may look beautiful and inviting, but 20,000 gallons of cold water can quickly derail any plans of an afternoon swim. With the Sta-Rite SR400NA, however, your pool’s water temp can stay just right, pun very much intended, so you can get the most out of your investment and maximize your pool enjoyment.

Designed for super-fast heating, the powerful and compact Sta-Rite SR400NA can effortlessly transform your pool into an irresistible destination on cool nights. In addition to its heating capabilities, this popular pool heater is also equipped with a number of technologically advanced features, such as smart electronics and a rust-proof exterior, adding to its performance and boosting your relaxation and enjoyment.

Reliable, durable, energy-efficient, and easy to use as well, the pool heater checks every box and is a great choice for any pool or spa owner.

The Limitations

Truthfully, there aren’t many cons associated with it. Although there are more affordable options on the market today, there are more expensive ones as well, so it’s competitively priced for its performance capabilities.

Therefore, the only true con would be the need for a Fireman’s Switch, which shuts down the heating element 45 minutes before shutting off the pump. This allows the pool heater to cool down properly instead of igniting like a tinderbox.
