Let’s Dive into Raritan 20-Gallon Hot Water Heater w/Heat Exchanger
The Raritan 20-Gallon Hot Water Heater w/Heat Exchanger is more than just a device for heating water; it’s a gateway to comfort and convenience on the water. Manufactured by Raritan, a name synonymous with quality marine products, this heater promises a steady supply of hot water for those crucial moments – a warm shower after a long day of fishing, or easy cleanup after preparing a meal. With its dual heating capability via 120V electricity and engine heat exchange, it’s designed to provide hot water regardless of whether you’re at the dock or underway.
Living aboard my sailboat for extended periods, I’ve faced the constant challenge of limited hot water. Shorter showers became the norm. The allure of consistent hot water, especially when away from shore power, drove me to seek a solution. The Raritan 20-Gallon Hot Water Heater w/Heat Exchanger seemed like the perfect fit.
Upon unboxing, I was immediately impressed with the unit’s robust construction. The dense foam insulation hinted at efficient heat retention, and the cylindrical design suggested durability under pressure. It was noticeably heavier than my previous, smaller heater, but the promise of abundant hot water outweighed any concerns about installation.
I considered the Isotemp Basic 25 and the Kuuma 11-Gallon Water Heater. The Raritan edged them out because of its reputation for reliability and the readily available customer support offered by Raritan. Initial impressions were positive. It felt like a well-engineered piece of equipment ready to solve my onboard hot water woes.
Real-World Testing: Putting Raritan 20-Gallon Hot Water Heater w/Heat Exchanger to the Test
First Use Experience
My first test involved connecting the Raritan 20-Gallon Hot Water Heater w/Heat Exchanger to both shore power and my boat’s engine. I was eager to see the heat exchanger in action. After running the engine for about an hour, the water temperature climbed impressively. The hot water lasted through multiple showers and several rounds of dishwashing.
I tested the heater during a late-season fishing trip in the Puget Sound. The weather was predictably cold and damp. The Raritan performed admirably, providing a much-needed morale boost after a day battling the elements. The electric heating element maintained a consistent temperature even during periods of low generator output.
The installation was straightforward, though connecting the heat exchanger required careful planning of hose runs. No adjustments were needed initially, and the water temperature was comfortable right from the start.
Extended Use & Reliability
After six months of continuous use, the Raritan 20-Gallon Hot Water Heater w/Heat Exchanger continues to deliver consistent performance. There are no signs of leaks or corrosion. The polymer jacket still looks new.
I periodically inspect the replaceable magnesium anode and replace it when needed to protect the tank from corrosion. Flushing the tank annually helps maintain optimal efficiency and prevents sediment buildup. Compared to my previous heater, the Raritan requires less frequent maintenance and provides a much more reliable hot water supply.
