Suburban Mfg 5320A Direct Spark Ignition, Dsi 6 Gallon Advantage Water Heater Saw6D Review

One Month Later: Suburban Mfg 5320A Direct Spark Ignition, Dsi 6 Gallon Advantage Water Heater Saw6D Review

The journey to a consistent supply of hot water in my mobile workshop, a converted cargo trailer, has been an ongoing saga. After years of wrestling with an aging, inefficient aluminum-tank water heater, the search for a more robust and reliable solution led me to the Suburban Mfg 5320A Direct Spark Ignition, Dsi 6 Gallon Advantage Water Heater Saw6D. This particular model promised a significant upgrade, moving from the older aluminum tank technology to a more durable porcelain-lined steel tank, mirroring the construction found in many residential units.

My previous water heater had developed a slow leak and increasingly unreliable ignition, making even basic tasks like washing up after a dusty fabrication session a minor ordeal. I was looking for something that was a direct replacement where possible, easy to install with minimal modifications, and crucially, offered improved longevity. I briefly considered a tankless propane option, but the complexity of installation and potential for inconsistent flow rates in a mobile setting steered me back to a traditional tank-style heater. My initial impression upon unboxing was of a solid, well-built appliance; it felt significantly more substantial than its predecessor.

There was an immediate sense of relief and anticipation, knowing that the days of lukewarm showers and chilly hand washes might soon be behind me. This replacement part, while a significant investment, felt like a crucial step towards making my mobile workspace more functional and comfortable.

Real-World Testing: Putting Suburban Mfg 5320A Direct Spark Ignition, Dsi 6 Gallon Advantage Water Heater Saw6D to the Test

First Use Experience

The installation was performed in my trailer workshop, a confined space where I often tackle welding, metal fabrication, and general repairs. This means the environment can be dusty and occasionally subject to minor impacts. I tested the unit’s performance primarily for its intended purpose: providing hot water for cleaning tools, hands, and for occasional personal use.

During the initial startup, the direct spark ignition system was notably quick and responsive, a welcome change from the finicky pilot light I was used to. The water heated up within a reasonable timeframe, allowing me to test its output for washing greasy hands after a particularly messy engine overhaul. The water pressure was consistent, and the temperature held steady, even during extended use while cleaning multiple sets of tools.

There were no significant issues or surprises during the first use, which was a relief for any appliance replacement. It was immediately intuitive to operate, with the familiar controls for gas ignition and temperature setting.

Extended Use & Reliability

After a month of consistent use, the 6-gallon Advantage water heater has proven to be a workhorse. It’s been called upon multiple times a week, often for tasks requiring a good volume of hot water, such as cleaning weld spatter off metal parts or rinsing off plaster dust after a drywall repair project inside the trailer.

Durability has been impressive so far; there are no visible signs of wear and tear, despite the occasional bump against a workbench or tool bag. The porcelain-lined steel tank feels incredibly sturdy, and I haven’t noticed any leaks or corrosion, which was my primary concern with the old aluminum unit. Maintenance has been straightforward, mainly involving periodic checks of the anode rod, which conveniently doubles as the drain. Cleaning is as simple as draining the tank and flushing it out, a task I performed once after a particularly dusty week.

Compared to my previous unit, this Suburban heater is a revelation. It’s far more efficient, heats water faster, and the direct spark ignition eliminates the hassle of manual lighting. It certainly outperforms budget replacements and feels built to last, like higher-end residential units.

Breaking Down the Features of Suburban Mfg 5320A Direct Spark Ignition, Dsi 6 Gallon Advantage Water Heater Saw6D

Specifications

This unit boasts a 6-gallon capacity, which is standard for many RV and mobile applications, and perfectly adequate for my needs. The Input BTU/h is rated at 10,000, a solid figure that contributes to its efficient recovery. Its Recovery Gals./Hr. is listed as 8.48 for gas, meaning it can heat a significant amount of water in a relatively short period.

The core of this model is its porcelain-lined steel tank, a significant upgrade that provides excellent resistance to corrosion and extends the lifespan of the unit. This construction is backed by a 3-year limited tank warranty, offering peace of mind. The Direct Spark Ignition (DSI) system ensures quick and reliable lighting, and it’s designed to work with an indoor mounted switch (Switch 234589) for gas ignition control.

The industry-exclusive flue tube is designed to slow down the combustion process, which helps transfer more heat to the water in the tank. This feature is crucial for maximizing efficiency and ensuring a quicker recovery time between uses. While it does not include an optional Incoloy Electric Element, the design suggests compatibility for future upgrades should the need arise, offering a dual-energy heating option. The unit is also supported by a 2-year limited warranty on the overall appliance.

Performance & Functionality

The primary function of the Suburban Mfg 5320A Direct Spark Ignition, Dsi 6 Gallon Advantage Water Heater Saw6D is to provide hot water, and it excels at this. The 10,000 BTU input ensures a rapid heating cycle, and the 8.48 gallons per hour recovery rate means I’m rarely left waiting for hot water, even after multiple uses. The Direct Spark Ignition is a highlight; it fires up instantly with a satisfying click and flame, a stark contrast to the temperamental pilot lights of older models.

Its main strength lies in its robust construction and efficient heating. The porcelain-lined steel tank feels incredibly solid, and the increased heat transfer from the specialized flue tube is evident in how quickly the water reaches temperature. A minor point of improvement could be an even more intuitive user interface for temperature selection, though the current dial is perfectly functional.

This water heater absolutely meets and exceeds expectations for its intended use in a mobile workshop setting. It delivers reliable hot water consistently, handling the demands of cleaning and personal use with ease.

Design & Ergonomics

The design of this water heater prioritizes function and durability. The porcelain-lined steel tank is the standout feature, giving the unit a substantial feel that inspires confidence in its longevity. The exterior is finished in a way that resists minor scuffs and scratches common in a workshop environment.

Operationally, the controls are straightforward: a simple dial for temperature adjustment and a dedicated switch for the Direct Spark Ignition. While it doesn’t have the sleek aesthetics of some high-end residential appliances, its utilitarian design is perfectly suited for its application. The unit is designed for an indoor mounted switch, which simplifies the user interface and keeps the main appliance relatively clean and unadorned.

The build quality is apparent from the moment you handle it; it’s a heavy-duty appliance built for demanding conditions. There’s no particular learning curve; anyone familiar with basic water heater controls will find this unit easy to operate immediately.

Durability & Maintenance

Built with a porcelain-lined steel tank, the Suburban Mfg 5320A Direct Spark Ignition, Dsi 6 Gallon Advantage Water Heater Saw6D is designed for extended service life. Under normal use in my mobile workshop, which can be more demanding than a typical RV environment, I expect this unit to last many years without issue. The 3-year limited tank warranty reflects the manufacturer’s confidence in its durability.

Maintenance is refreshingly simple. The anode rod, integrated with the drain valve, makes periodic flushing and inspection straightforward. I plan to inspect the anode rod annually and replace it as needed to prevent corrosion and ensure the tank’s integrity.

The only potential point of attention is ensuring the Direct Spark Ignition system remains free of excessive dust or debris, which is manageable with basic cleaning. Overall, it’s a low-maintenance appliance that rewards users with reliability.

Accessories and Customization Options

This particular model, the SAW6D, does not come with the optional Incoloy Electric Element or its associated switch. However, the description notes that the SAW6DEL Advantage Water Heater is a direct replacement for models utilizing an indoor switch for both LP gas ignition and electric element operation. This implies that the infrastructure for adding an electric element, if desired later, might be present or easily adaptable, offering a path to dual-energy heating.

The crucial accessory for its operation is the indoor mounted switch (Switch 234589) for controlling the gas ignition. Without this, the direct spark system cannot be activated. While it’s a separate purchase, it’s an essential component for this unit’s functionality.

There are no other significant customization options inherent to the water heater itself, beyond the potential electric element upgrade. Its design is focused on robust performance rather than extensive user modification.
