  • More than I thought I'd get!!!!

    We needed a water heater for our weekend home, thought wed try this and found it on Overstock.com 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 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 120F. 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.

Questions & Answers

Get your product questions answered right here.
  • Would this unit deliver enough heat to operate a 30'x40' concrete slab hydronic radiant system?

    • Hello Shop, unfortunately the EL10 has a 20 min shut of valve that is not made for radiant heat. Have a great day!

  • What kind of flew will I need to mount this inside the house in small room? Sorry about the first question

    • Unfortunately, at this time, the information is not available. As the information becomes available, the site will be updated. Have a great day.

    • 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.

  • What changed of flew will I need to mount inside of house and do you sell it

    • Unfortunately, at this time, the information is not available. As the information becomes available, the site will be updated. Have a great day.

  • Can this unit use natural gas

    • Thank you for your question jack27. No, unfortunately the L10 cannot be converted to natural gas. Have a great day.

  • Can this unit be mounted indoors with additional chimney?

    • 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 Overstock.com.

  • The water heater shut off after 2 minutes or so anybody know why?

    • Thank you for your interest. We are unable to determine why from here. Please consult the paperwork that accompanied this item and call the customer service number enclosed. Feel free to contact us again with any further questions.

  • Can this be attached on outside wall of my log cabin? Can it be operated from within cabin without having to go outside?Does it just vent into the air...with no need for extra flue?? thanks

    • 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.

    • No if it freezes will damage unit.

  • Does this unit need to be brought inside during freezing weather?

    • No, this unit is able to withstand cold temperatures and can remain outdoors.

  • Can this unit be converted to propane?

    • Yes, it comes with the CSA regulator that you would use for a standard 20-pound grill propane tank.
