Product Description

The incredibly efficient Eccotemp FVI-12 Natural Gas Tankless Water Heater uses an intense gas-fired flame to instantly heat water the moment it passes through the unit, so as long as you feed water in, hot water will come out! Comes ready to install. With the included horizontal vent kit, this Eccotemp FVI-12 Natural Gas Tankless Water Heater can be installed for indoor use right out of the box. Great for cabins and smaller homes, so you don't bust your budget for a hot shower! The Eccotemp FVI-12 Natural Gas Tankless Water Heater is a manual water heater. This means that any water temperature adjustments must be made at the face of the unit using the knobs for water flow and gas pressure. Mixing cold water at your output source is not recommended. Have questions? Contact support at 1-866-356-1992 or support@eccotemp.com.

Perfect for a small house and the family that understands how the unit works and works with it
Update after 1yr 6mo. Still working great. my gas and electric bill is averageing $104mo. Used every day with two people (one thing we had to do is run the hot water just before starting the cloths washer because these new effeciant washers pulse little amouts of water to fill and it does not give time for the heater to turn on).This water heater lived up to exactly the expectations I was hoping for. It was an extremely low cost replacement for my 1100 sqft 1 bath home. After reading all the reviews I knew it was going to be finicky but I thought with a few adjustments it would be worth it. And it was. It never made sense to me to add cold water to hot water in the shower cooling off the hot water you just paid money to heat up so when I read someone else's review about putting the shower all the way to hot and having someone adjust the temp on the unit while you're in the shower that sets the Baseline for the whole house perfectly. Now when I get in the shower I put it all the way to hot pull it on and it heats up to the right temp perfectly every time (the left knob). The other adjustment is the right knob for water flow and once I got it where I liked it for the shower I drilled bigger holes in the aerators on the sinks until each one would activate the heater properly. The other benefit is going from the old unit which was oversized for the house to this very small unit is saving me money on my gas bill. One thing that you have to understand with this unit is if you add more cold water to cool it then the water on the hot side run slower and sits under the flame longer and then heats up and get the temp right back where you were if that makes sense. So if you want a cooler shower you have to slowly turn the water valve till the showers a little colder than you want and then wait till that hot water gets hotter mixing with the cold water.
