Specs


The first thing you should know is that the FVI-12-LP is a small, compact unit that doesn’t require a lot of space. It’s only 4 x 15 x 24″ and 20 pounds!

You can install this water heater absolutely anywhere in your home, including under sinks and inside supply closets.

As for power, while it doesn’t generate the energy that bigger units do, its low demands come with a silver lining. For example, while it only offers 100 volts, it only requires75,000 BTUs.

According to Eccotemp, you can save up to 50 percent on your energy bill every month just by switching to the FVI-12-LP.

Last but not least, the flow rate of the FVI-12-LP is 3.4 gallons per minute (GPM).

This is enough for 1-2 bathrooms with multiple demands on sinks, showers and appliances. If you like to run the dishwasher or do a load of laundry during your baths, this unit will accommodate you.

Performance


The FVI-12-LP runs on liquid propane, so if you aren’t familiar with propane and natural gas tankless water heaters, here’s a basic rundown of their operation:

1. Internal sensors detect cold water rushing through the pipes.
2. Live burners turn on and warm up the heat exchangers.
3. Cold water circles the heat exchangers until it’s heated to the right degree.

Since a live flame is involved, you’ll need to install a venting system for the fumes, but the good news is that Eccotemp includes stainless steel vents with your order.

We’ll talk about that more in the installation section.

As for everyday functionality, you won’t have a problem using the FVI-12-LP.

There’s a digital interface on the box where you can adjust the temperature to your exact specifications, and there are even separate knobs for gas and water.

This isn’t a fancy model where just touching it requires an extended how-to guide.

You can figure out the FVI-12-LP by simply looking at it.

Heat Output and Flow


As previously mentioned, the flow rate of this unit is 3.4 GPM, and that’s enough to service either multiple bathrooms or a kitchen and bathroom at the same time. Please note, however, that the FVI-12-LP isn’t designed for large homes.

It’s a small unit meant to be used in small spaces.

If you have excessive hot water demands, you may need to install more than one FVI-12-LP on your property.

Temperature-wise, the FVI-12-LP will deliver exactly what you need and when you need it.

There are very few flow delays reported with this product, so your temperature and water pressure are all but guaranteed.

Another great thing about the FVI-12-LP is that it only uses energy when it’s actually turned on.

It isn’t a so-called “energy vampire” that runs up your utility bill when you least expect it. The FVI-12-LP stays silent until it’s actively running, and even then, it uses much less energy than other water heating systems.

Installation


While the FVI-12-LP isn’t excessively difficult to install, care should be taken since it’s a liquid propane unit that will produce fumes while in use. You might want to let a certified Eccotemp technician do the installation for you just to be safe.

If you do want to tackle it yourself, however, here are a few of the things you might need to get the job done:

  • Regulator
  • Circuit breakers
  • Ground lines
  • Copper wiring

A stainless steel venting system is included with your order, so you won’t have to worry about that. You can also buy add-ons and extras if you want more customization options.

General Use


Every product has an Achilles heel. Before purchasing any tankless water heater, including the FVI-12-LP, you should take a good look at the pros and cons.

Pros:

  • Small, compact unit that can be installed anywhere
  • Extremely energy-efficient
  • Low price

Cons:

  • Not suitable for large homes
  • Requires venting system for fumes
  • Non-lifetime warranty

The Final Verdict


If you’re looking for the best propane tankless water heater on the market, you’ll definitely want to consider the FVI-12-LP. Not only is it functional and affordable, but you’ll be helping the environment by using it, too. I’d give it a solid four out of five stars in terms of overall performance.
