Questions & Answers

Can this unit be used with a 100lb propane tank?

Asked by: Mpg2019
Hello, The NG unit means Natural gas. They will not be able to be used due to the gas burning differently. propane is a heavier gas while natural gas is lighter. For more details, please contact Marey's Customer Support at Toll-Free Phone Support - USA: +1 (855) 627-3955 or through email: customerservice@marey.com

How does it work?

How does it work?
Asked by: Marlene
The water is heated as it flows through the unit, on demand, when you turn on your faucet or shower. We installed it in a rental unit and it works great!! Cuts down on energy costs of heating a bunch of water in a tank. It's large and should be installed inside vs outside so you do need the space for it. But highly recommend it!

Works great but you need to find a balance for the water flow so it fires up because if you have the flow to high it won't fire until you reach that flow, it also won't fire if there's air in the water lines. The temp. does drop after flowing a bit so i turned up the temp a little. Really easy installation. I used shark bite fittings and pex line. The hardest part was getting the lines off the old tank and then i just incorporated them into the new heater. If i didn't have to get parts i would have had it installed in under 2 hours. All in all i'm very happy.
