Q:I ordered the 45H-LP 6.8gpm and received a unit with 45H-LG on the label fixed to the side of the hot water heater. Is this propane or natural gas?
by|May 8, 2021

A:  Hello there! The 45H-LG is the same as the Liquid Propane, our Natural gas is labeled as NG, therefore what you have received is the 45H series for Liquid Propane. If you have any questions or concerns, please reach out to our technical support team via live chat, setting up a call, or creating a support ticket at support.eccotemp.com. We will be waiting and are always happy to help! Thank you and have a wonderful day!

            I don't recommend this water heater unless you are very confident your house has enough water pressure. This unit only kicks on if it detects enough water flow.

            The 2000 ft maximum elevation is the reason it was returned….the elevation is not obvious in the internet verbiage!

            Support desk not helpful at all
            My unit is still under warranty and not functioning correctly. Help desk was useless and strung me along until I gave up. I’m getting rid of this product and going with an electric water heater. I’ve spent more time and money than a new one would have cost. And did I mention it’s still under warranty? Awful customer service. Warranty is meaningless.

              When I hooked it up nothing happened for about a minute then it made a pop sound and it caught on fire. I when I contacted the manufacturer all I got was a run around. Now I have a 450.00 piece of junk that never worked. I would tell anyone interested in buying one don’t do it.

                This newer model replaced an older, smaller Eccotemp. Installation was relatively easy with Sharkbite water heater connection kit, which saved a ton of time and frustration with sweating copper fittings onto pipes holding water.
