  • This is a great product

    This is a great product , once you set it up right..... here are a few helpful tips ,when setting up the unit get your self a whole house filter this will make the unit last longer and have trouble free operation .Next thing is to set it up with the hots water setting that you would shower at or wash dishes, By doing that you will never get burned , next thing is that you turn on a shower full blast and then lower the water temp by adding small amount of cold water . By doing this the flow sensor will keep the unit on and you will have hot water at a even flow ,if you have trouble with the unit shutting off on you when you take a shower just remove the flow restrictor on the the shower head it should work just fine . once you know how to use ondemand water heater your savings will pay for unit in less than a year i enjoy mine . have a great day and think green on demand....

  • Over Rated

    The Good: Overstock is an awesome company and very glad I ordered through them. This water heater is very simple and operates well. ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- The Bad: The unit is severely over rated. With the gas on max. and water flow on min. the best this unit will do is heat water to around 120°F. On this setting the flow is about 1 gallon/minute...approx. 40% of its rated capacity. At rated capacity of 10 LPM (2.65 GPM) the water is only slightly warmer than body temperature. I bought it to use for one bathroom and it will barely be able to handle this job...if not be inadequate. I will be upgrading to a larger unit later but at least I have the utilities set up for it. ...and...of course this water heater is made in China. This same company also makes a L5 unit and I can only imagine it would be nearly useless.

  • Great product

    purchased as a temporary unit while permanent unit is replaced under warranty and we don't want to switch back to the permanent unit. Delivered on time, unit installed easily, simple settings, no limit to the hot water that we have found. This unit doesn't use a lot of gas to run.

  • Super value--good for my cabin

    Installed easily and works good with my 12volt pump. Good for remote locations like my cabin which is off the grid. As I don't use it daily, it usually takes a few starts to clear the gas line but the water comes out hot and efficient.

  • Perfect

    This works the way it was made to work. We put it in a one bedroom cabin where it is hooked up to a small propane tank. Everything we needed to hook it up and get it going came with the heater. Plenty of hot water for showers.

  • More than I thought I'd get!!!!

    We needed a water heater for our weekend home, thought we’d try this and found it on at a great price. Really easy to hook up, and use! There was a little adjustment and tweaking but we had very, very hot water (130+) out of a well with 20 degree outdoor temps, at a good rate and pressure. If this thing works for two years we have made out money back having to heat 40 gallons no longer.

This unit is made for OUTDOORS. An indoor unit would get its combustion air from a double wall flue system. This unit doesn't have that feature. Combustion air comes from vents around the cabinet. jonsid on Apr 29, 2014

Can this unit be mounted indoors with additional chimney? circlebay on Sep 18, 2013
Subscribe to Answers
Answer This Question

This unit can be mounted indoors but with the additional chimney would depend on where you are going to mount it. Most of these are designed for small bathrooms or log cabins and the gas line is for a propane tank hook up. The unit if mounted in a small combined space would need adequate ventilation and a chimney or flew on it and if mounted in a room say a log cabin with a 2 story vaulted ceiling with vents then no chimney or flew would be needed. thank you for shopping overstockcustomercare1 on Sep 24, 2013

Answer This Question

You would need to read the installation instructions. It sounds like it is a common item for cabins by reading the first sentence of the description. It doesn't mention anything about an extra flue. overstockcustomercare1 on Oct 11, 2012
