Specs


The V65EN is a “whole house” unit, meaning that it will service your entire home from a single box. You won’t need to buy multiple units to install at every sink. Just mount the V65EN and forget about it.

In terms of flow rate, you can expect the V65EN to deliver up to 6.6 gallons per minute (gpm) depending on the temperature outside.

If you live in a moderate climate, you’ll get all 6.6 gpm; if you live somewhere very cold, you might get somewhere in the range of 4-6 gpm.

As for power technicalities, the V65EN requires 150,000 BTUs. This puts it right on par with other Rinnai models, so you aren’t losing anything from this model just because it’s light and compact.

Speaking of weight, the V65EN clocks in at 48 pounds, a very nice number for a natural gas tankless water heater.

They can be quite cumbersome since there’s so much going on inside the box. The V65EN, however, has streamlined its internal operations and can therefore be mounted anywhere outside your home.

Performance


As a natural gas tankless water heater, the V65EN works through an internal system of burners, sensors and heat exchangers.

When cold water is detected in the pipes, the burners fire up under a heat exchanger, and the water circles the heat exchanger until it matches the pre-set temperature you’ve chosen.

Again, the VG5EN is a whole-house unit, so you won’t have to worry about using the kitchen and bathroom facilities at the same time.

Take a shower while the dishwasher is running; fill the tub while someone else is washing the car. It can handle simultaneous usage with ease.

That said, you may or may not have a problem with the V65EN and larger homes. While it works as advertised with small to moderate-sized properties, it isn’t designed for especially big residences.

If you live in a larger home, the performance of your V65EN might be different than that of your neighbours.

Heat Output and Flow


The pre-set temperature of the V65EN is 120°F. When you buy a Rinnai remote control, however, you can increase your range from 98°F to 140°F. This is enough to have hot, luxurious showers or to completely eliminate those stains from your child’s soccer uniform with scalding hot water.

As for flow, you can expect up to 6.6 gpm, though I should mention again that this number may fluctuate depending on your location.

If you live in an extremely snowy or frigid area, your flow rate might dip because of the extra effort required of your heating unit.

Installation


Rinnai products aren’t very difficult to install, and the V65EN is no exception. While I do recommend allowing a trained technician to handle the finer details, it shouldn’t be that hard for a layman to figure out, especially since Rinnai includes a detailed instruction manual with every purchase.

Depending on the tools and materials you already have at hand, you may or may not need the following:

  • Valves
  • Vents
  • Ground lines
  • Circuit breakers

Remember that the V65EN is also compatible with a variety of add-ons and extras, so if you want a remote temperature controller or a special venting system, check out other items available from the Rinnai line.

General Use


Alas, every product comes with a downside. Make sure you understand the pros and cons of the V65EN before making your purchase.

Pros:

  • Efficient, whole-house unit
  • Easy installation and maintenance
  • Affordable natural gas model

Cons:

  • Not suited for larger homes
  • Must be mounted outside
  • Flow rate might diminish in colder climates

The Final Verdict


On a scale of one to five, the V65EN ranks a solid four. It isn’t a completely flawless unit, but it’s one that I can and have recommended to homeowners quite a bit, especially those who live in smaller homes and more temperate climates.

If you don’t need a lot of bells and whistles from your tankless water heater, the V65EN is the unit for you. Check it out on Amazon to learn more.
