Using the included energy factor rating as a benchmark, the Rinnai V65IN conjures up a respectable 0.82 energy factor. This overall energy efficiency reduces heat pump loading and lowers energy bills as it climbs higher. In other words, the higher the EF, the higher the efficiency rating. Taking this energy-oriented sweet spot into account, what other features make this unit stand out? Well, it has a small control panel mounted on the lower half of the front panel, plus it’s again fueled by Natural Gas.
Again, it’s compact, but that’s a common feature among tankless water heaters. This time around, the 150,000-BTU energy output and 6.6-GPM capacity suggest you’ll get the best out of this gas-fueled model if you install it in a mid-sized property, not a large family home. Aimed at small families, the Rinnai V65IN is a high-performance device.
Still in budget-friendly territory, this is a feature-rich gas waterless heater. Output and capacity ratings are satisfactorily high, then there’s an enhanced scale detection system, a temperature lock, and a leak detection function to tempt your itchy fingers to dip into your wallet.
