The Girard 2GWHAM On-Demand Gswh-2 Tankless RV Water Heater: Review from Real Use
For anyone who has lived the RV lifestyle, the consistent availability of hot water is more than a luxury; it’s a fundamental necessity. My own journey into the world of mobile living and remote work quickly highlighted the limitations of traditional RV water heating systems. The Girard 2GWHAM On-Demand Gswh-2 Tankless RV Water Heater entered my life not as a whim, but as a solution to a persistent problem: running out of hot water mid-shower, especially when guests were present. This unit promised an endless supply, a significant upgrade from the 6-gallon tanks that are standard in many rigs.
The decision to upgrade was driven by a specific scenario: a chilly morning in the mountains, a fellow traveler needing to wash up after a hike, and the dreaded realization that the RV’s water heater had just been depleted. It was an uncomfortable moment that underscored the need for a more robust solution. I had been eyeing tankless options for a while, and the Girard model, with its focus on user feedback and advanced control, seemed like the most promising candidate. My initial impressions of this unit were focused on its compact size and the substantial feel of the digital controller. It felt like a significant step up in technology from what I was accustomed to. While I briefly considered other brands known for tankless RV heaters, the specific features highlighted by Girard – particularly the intuitive digital interface and the promise of consistent temperature – tipped the scales. The first reaction upon seeing it installed was one of anticipation, a quiet hope that this would indeed solve my hot water woes.
Real-World Testing: Putting Girard 2GWHAM On-Demand Gswh-2 Tankless RV Water Heater to the Test
First Use Experience
My initial testing of the Girard tankless water heater took place during a week-long excursion in a more remote campground, where consistent electrical and water hookups were sometimes intermittent. This environment provided a perfect backdrop for evaluating its performance under less-than-ideal conditions. The installation process itself was surprisingly straightforward for someone with basic RV plumbing knowledge, and the unit fired up on the first attempt.
Operating the digital controller was intuitive from the start; it felt much like adjusting a smart thermostat. There was no steep learning curve, which was a welcome relief after wrestling with other complex RV components. The most immediate positive surprise was the speed at which hot water became available – a noticeable improvement over waiting for a tank to heat up.
One minor quirk I encountered early on was the sensitivity of the flow sensor. If water flow dropped too low, the burner would momentarily shut off. It took a few instances of slightly fluctuating water temperature in the shower to understand that a consistent, moderate flow was key to maintaining uninterrupted heating.
Extended Use & Reliability
After several months of consistent use, including multiple extended trips and a few periods where the RV served as a mobile office, the Girard GSWH-2 has proven itself to be a reliable workhorse. It has become an indispensable part of my mobile setup, providing hot water for everything from lengthy showers to washing dishes for a small group.
The durability of the unit has been impressive. Despite being mounted externally on the RV, it has endured road vibrations, varying weather conditions from desert heat to mountain chill, and the occasional splash of mud. There are no visible signs of cracks or significant wear on the exterior casing or the control panel. The hinged door mechanism for accessing the unit remains smooth and easy to operate, a welcome change from the fiddly latches found on older RV appliances.
Maintenance has been minimal. A quick wipe-down of the exterior and ensuring the intake and exhaust ports are clear of debris are the only tasks required. I haven’t experienced any performance drops, leaks, or issues with the burner cycling, which speaks volumes about the quality of its internal components and the effectiveness of its on-board micro-processor. Compared to the older, tank-style heaters I’ve used in previous RVs, this tankless model offers a vastly superior experience in terms of both convenience and reliability.
Breaking Down the Features of Girard 2GWHAM On-Demand Gswh-2 Tankless RV Water Heater
Specifications
The Girard 2GWHAM On-Demand Gswh-2 Tankless RV Water Heater is a compact and powerful unit designed for the unique demands of RV plumbing. It boasts an impressive 42,000 BTUs, which is crucial for delivering consistent hot water flow at a rate suitable for simultaneous use. The unit operates on a 12V power system, drawing less than 3 A, making it remarkably energy efficient for its output.
A standout specification is its digital controller, which allows for precise temperature adjustments between 95°F and 124°F. This temperature range is adjustable and can even be switched to Celsius, offering significant flexibility for different user preferences and safety requirements. The inclusion of freeze protection is another vital specification for RVers who travel in colder climates, as it is designed for winter use.
The silicone exhaust ring is a clever design element that simplifies the installation of the exhaust tube, ensuring a secure and leak-free connection. This attention to detail in the specifications translates directly into a more user-friendly and dependable appliance.
Performance & Functionality
In terms of its primary function – delivering hot water – the Girard 2GWHAM On-Demand Gswh-2 Tankless RV Water Heater performs exceptionally well. The endless hot water capability is not an exaggeration; once the system is running, it consistently supplies hot water as long as there is propane and water flow. This is a game-changer for RV living, eliminating the stress of depleted hot water reserves.
The key to its success lies in the on-board micro-processor. This intelligent system continuously monitors incoming cold water temperature, flow rate, and outgoing hot water temperature. It then regulates the burner precisely to maintain the set temperature, providing a steady, unwavering stream of hot water. This eliminates the “cold burst” phenomenon often experienced with less sophisticated tankless systems.
A notable strength is the ability to pre-set the hot water temperature, which is particularly beneficial for families with young children. This feature significantly reduces the risk of scalding accidents, offering peace of mind. The unit’s quiet, brush-less motor contributes to a pleasant overall experience, as it operates with minimal noise intrusion.
Design & Ergonomics
The design of the Girard GSWH-2 is a thoughtful blend of practicality and user-centric features. The unit itself is relatively compact for its heating capacity, allowing for efficient installation in the often-limited space within an RV. The exterior is finished in a durable material that has held up well to the rigors of travel.
The interior wall-mounted digital controller is a significant ergonomic advantage. Its clear display provides real-time operating information, and the simple button interface makes adjusting settings effortless. The ability to switch between Fahrenheit and Celsius is a thoughtful touch for international travelers or those who prefer metric.
A particularly well-executed design element is the water heater door. Unlike older models that relied on difficult-to-operate twist latches, the Girard features a hinged door with a sliding latch. This allows for incredibly fast and easy access to the unit for maintenance or troubleshooting, a small detail that makes a big difference in practical use.
Durability & Maintenance
Based on my extended use, the Girard 2GWHAM On-Demand Gswh-2 Tankless RV Water Heater appears to be built for longevity. The use of robust materials and the intelligent design, particularly the freeze protection feature, suggest it can withstand the harsh conditions RV appliances often face. The sealed nature of the unit, combined with the efficient exhaust system, minimizes potential points of failure related to moisture or particulate ingress.
Maintenance is commendably simple. The user-friendly access door allows for easy inspection of connections and the exhaust vent. Keeping the intake and exhaust ports clear of obstructions is the most critical maintenance task, ensuring optimal performance and preventing overheating. The brush-less motor is inherently more durable and requires less maintenance than brushed alternatives.
While I haven’t encountered any specific failure points, it’s always wise to periodically check propane connections and the water inlet for any signs of wear or leaks. The overall construction gives the impression of a product designed for reliable service over many years.
Accessories and Customization Options
The Girard 2GWHAM On-Demand Gswh-2 Tankless RV Water Heater comes with its essential components, focusing on the core functionality. The most critical “accessory” is the digital controller, which is integrated into the system and is not a separate add-on. This controller is the primary interface and is crucial for operating the unit efficiently and safely.
The product description doesn’t mention specific aftermarket customization options in the traditional sense, such as interchangeable heating elements or different exhaust kits beyond the standard one. However, the design allows for compatibility with standard RV propane lines and 12V power systems, which are universal. The ease of aligning the exhaust tube with its silicone exhaust ring makes it adaptable to various RV configurations.
While not an accessory, the visual diagnostics feature on the controller is a significant aid for troubleshooting, effectively acting as a built-in diagnostic tool that simplifies problem-solving. This proactive design choice reduces the need for specialized tools or external diagnostic equipment.
