I am planing on using it in a food truck. Do I have to remove the water heater in the off season, where the outside temps can reach -20 in the winter?
Asked by: EddiesFoodTruck
I believe there is a drain located at the bottom. If not you could undue the water supply lines and use compressed air to blow any remaining water from the unit. Just use 50 psi or less air supply to prevent damage to the unit.

Can you supply pre-heated water to this and have the burner unit come on only when needed? For instance, if you use your wood stove or solar power to pre-heat water to an old water heater being used only as a storage tank. Then have that pre-heated water supply this device?

This unit is activate by water pressure, not water temperature.

2.0 GPM Liquid Propane Tankless Gas Water Heater is rated 4.0 out of 5 by 76.
Rated 5 out of 5 by from works great... works great
Date published: 2019-06-07
Rated 5 out of 5 by from Far From Idiot-Proof, but Perfect for RV I took a gamble on this product and have been absolutely blown away by value, quality and function. I have seen reviews saying, "I set it up and it worked great, and then it just stopped." Same happened to me, and while I didn't find the answer in the manual (it might be in there somewhere), I did discover that the igniter requires the water pressure knob to be almost at lowest possible point. The first time you turn on the water and nothing happens, you think, "Awwww, no - it WAS too good to be true." Or at least I did. But being a guy who leans more toward fiddling about with knobs than re-reading a manual, I discovered that the igniter requires a low water pressure setting. The other thing that came as a bit of a surprise was that I spent much more on parts and tools required for installation than I did on the heater. And HD sells most, but not all, of those supplies. I had to get a 4" pellet stove insulated pipe and adapter from a stove shop. Actually, I probably could have ordered those along with the heater and gotten everything on the cheap from HD, but I guess I was assuming everything would be available off-the-shelf, and, since I really needed a shower, I ended up spending a little more at a stove shop. You will need: Water line, water shut-off valve, gas line, gas shut-off valve, thread seal for both, a 3' section of Insulated pellet stove pipe, adapter to fit pipe to heater collar, rubber roof collar, and a rain cap. I also had to buy a 6" hole saw and arbor, but if you already have those, you will spend about $50 less than the $300 I spent on installation supplies. We have been using this for three months now and are just delighted with it. The install might have cost more than we expected, but now that it's in, I can swap in a replacement in about 5 mins

Rated 5 out of 5 by from Work great right out of the box It came with a propane regulator, rubber gaskets and everything you need, except Teflon tape. The directions aren't that great so watch the Utube video by the Marley company. The water gets very hot. I hooked it up to a hose with rust in it and clogged up the intake filter. I reversed the intake/output to wash out the rust and it worked great.

Rated 1 out of 5 by from Disposable garbage I've already bought two of these heaters and both have had the same problem, the clicker stops working. This is due to the cheap D cell battery holder. The contact pins get loose and the battery cover lock pins break off since it's made out of cheap plastic. Aside from that, the second unit leaked water from the inside since day one. DO NOT BUY!

Even though Marey techical department stated could use code 40 plastic pipe for the exhaust preferred to use the metal one sold by Home Depot. Believe is safer when using a gas open flame appliance.

Rated 1 out of 5 by from Stay Away from this one!!! In the beginning, I was impressed because the installation was so easy, and the performance was excellent. But my happiness was not for long. Less that two weeks after installed, it stopped working and I had to return it. I should have read the previous (and only one) review of this product.
