1st I want to give a kudo’s to Mary, Gasland Customer Service Manager. I am very happy with the fix to my problem, my experience has been with a great Customer Service Department that stands behind their product. My set up. I used an old steel / porcelain bath tub. I plugged the over flow with a bolted on piece of cedar and then raised the tub water height by bolting on two cedar 2x4’s at about a 15 degree angle around the top, this lets me have a deeper tub for my 6 ft. frame. I can put my feet up on, the once the top but now, ledge with my feet still mostly under water. I have used marine spar varnish and silicone caulk to seal the cedar, but have to refinish every few years. So I am going to try “Pond Shield” with I refinish the cedar this winter. A piece of 1” clear suction hose is connected to the tub drain with a 1 1/4 ” to 1” clamp on type rubber reducer. With 1” hose connectors at tub and pump. Going to a 1 horse, stainless steel housing lawn irrigation pump (more forgiving then iron if accidental freeze up happens), I like the Utilitec pump. I built a small ‘pump house’, basically a hinged roof on an open sided 2x4 box frame. Keeps rain off in the summer and the pump is easy to pull when it starts freezing at night. I run a ¾” hot water type garden hose (I got a 50’er from Sears, which I cut to the lengths I need) to a standard house water filter. Then a 3/4“gated wye at the filter output. One for attachment to the Gasland outdoor water heater and another to bypass the heater, straight to the tub for running cleaning cycles. And again a length of the hot water garden hose for the water heater to the tub, the cut end just hanging into the tub. I made an 8” copper pipe to hose extension piece so connecting the output to the garden hose would be easier. For the intake side just another piece of garden hose coming from the filter. Both the intake and output have quick disconnect type connectors. All the garden hoses’ are wrapped in water heater hose insulation, available from any hardware store that has plumbing stuff. And then the brains of the outfit is an Inkbird 308 temperature controller outlet thermostat. The water circulates from the tub through the water heater till the water gets heated to the desired preprogramed temperature. The pump, which is hooked into the Inkbird receptacle, shuts off automatically at the selected temp. You can also set the thermostatic range for how cool it gets before turning the pump back on again. I use a heavy 12/3 outdoor extension cord with a GFCI. In the summer I use the GFCI to turn the pump on via the Inkbird. In about 10 or 15 minutes the tub water warms up to the 112 degrees I like. In the winter as long as it’s mostly above 20 degrees in the daytime, I take the pump and filter inside, drain the hoses and make use the of Gasland’s handy drain plug, I added a 2” long bolt as an extension to make pulling the drain plug easer. There is a female threaded end on the drain plug. When temperatures start hanging out between 0 and 20 during the day I will pull the heater as well. Takes me about 10 minutes to set it all up, a bit longer to pull and drain the hoses and all. When it’s this cold I never let the water not circulate, except when I’m actually in the tub. Just turn off the propane and set the sensor out of the hot water to keep the water circulating. If it’s going to start staying below zero with no warmer days in sight till spring, then it’s time to ‘pickle’ the whole set up till April. Thanks to global warming, in 2019 that was the 2ed week of December, 2020 mid-November and still hot tubbing. 20 years ago I would not have made it to Halloween. The tub is insulated and I use 1 ½ blue foam, double thick, to cover the tub, with a ¾ hole for the hot water hose, melted into the cover. Then a rubber cork to plug the tub drain. Even at zero the water is liquid for 3 days (or perhaps a thin crust of ice) and still doesn’t take more than 30 minutes to heat up from 33 degrees. For the summer I have a tub size wood frame with a clear plastic roof on poles with a mosquito net canopy held against the tub sides with elastic bands. It’s about 4 feet above the tub. I cover the water with a piece of plastic just to slow evaporation and keep the water cleaner when the tub is not in use. This canopy setup is replaced with the foam insulation covers, once the leaves and snow has fallen. Then 34% food grade H2O2, (or 29% for H2O2 used for hydroponics) and some chlorine, plus filtering the water a few hours every couple days like a swimming pool. I don’t like to use chlorine (bleach) so use as little as I can and put it in after a tubbing so it’s gone before I tub again but H202 is too expensive to use exclusively here in Fairbanks. I use about 15 filters a tub year, buying them in boxes of 50 each. In the summer I change the water every other week of so, using the tub water to wash vehicles or water the lawn. The 40 gallon Tub now holds around 70 gallons of water. Another cleaning must is a skimmer, I use a piece of 1 ½” PVC pipe, belled at the top, which friction fits over a piece of irrigation pipe. The irrigation pipe friction fits into the bath tub drain, with a little help of poly tape. The PVC end I can raise or lower to just the right level to create the skimmer effect. Just sucking off the bottom doesn’t clean the water nearly as well or quickly. I also use another piece of clear 1” suction hose which can be stuck into the “sunken skimmer” end and using one hand to seal the hose to the skimmer I can vacuum the bottom of the tub, stuff too heavy to float. I used an Aqua star on demand water heater for 20+ years, which took a lot of nursing and repairing over the years. It had a pilot light which ate the propane so I always had to manually light the Aqua Star every time I wanted to heat the water. The Gasland water heater has worked so much better, it always ‘just lights’ every time I turn on the water pump and seems to use less propane, I love it. Though after 6 months of living outside under an eve I made to keep rain off the heater, I did have to clean the connectors in the battery box when I changed the batteries, power wasn’t getting out of the battery box. Two small critiques of Gasland. It would be handy if they had manuals and troubleshooting guides on their web site. The only online manual I found was for one model posted by Home Depot. And while the manual states in three places to “orientate” the batteries correctly there are no + or – markings visible on the battery box. I guess they just expect everyone to ‘know’ the spring side is the negative side.

I’ve set this up as a dog wash in my shed, which has a cold water line for a hose but no hot water. Tapped into the hose line and I’ve run my own hose and sprayer so it can stretch outside. Works as advertised- unlimited warm water and overall a really nice solution to my problem. Cannot yet speak to longevity as I’ve only had it a few days. Couple of things to know: 1. Installation: the kit comes with 1 male and 1 female garden hose adapter for the input and output which is nice but it also means more connections to have to pipe tape and have leak potential. I’m a pretty decent plumber, but even with my permanent setup, ample tape use, and tightening with wrenches, there’s a slow drip leak on the input side that I decided to just live with after 3 attempts to reconfigure - I installed a shutoff valve in the line for when the machine’s not in use anyway. But I would assume that if you’re using this in a portable way and want to hook it up quickly to a hose and go that you’ll have to live with large leaks. 2. The machine definitely dials down the water pressure pretty dramatically- I have the full blast hose pressure going in the input and get more of a gentle rain out the output. It’s acceptable for washing a dog but something to be aware of if you need more pressure.

I ordered this as a way to take a warm quick rinse shower prior to using our pool & hot tub without having to do all of the plumbing work it would have taken to run a hot waterline to our backyard. My wife and I are very pleased since it works really well and is very simple to hookup and use. I am hoping not to need it for this but it occurred to me that we will also be able to take hot showers if we ever lose power after a hurricane.

I decided to try this propane heater after reading a recommendation for it in a review of another product. It was easy to install, works great, and I love the shower head. My only complaint was that the little plastic bracket included to mount the handheld shower on the wall didn’t actually fit the shower head. I ended up getting some ideas online and made a holder out of an old water bottle.

I had this thing setup and ready to go with in a hour of opening the box. The first thing I noted was a few water drops, I should have just packed it back up then, instead I carried on... (I took pictures afterwards and found many concerning items that look that not only was this a USED unit, it looks like somebody attempted to get it working see pics for details.) I followed all instructions and it would not fire up. The water ran smooth, the igniter clicked but no warm water. I tried two different 20lb propane tanks same results. I never smelled propane, and even after shutting off the LP tank and running the water on and off several times there was still gas pressure in the line when disconnected, My best guess is that the gas solenoid is faulty and not letting gas pass to the burner. I opened it up to check items per manual and found the igniting leads were all over the place, they are marked red and blue but no idea what that means. Only one would make spark, not sure if this is a how it’s supposed to function though. As I continued to diagnose the problem I found the metal housing was all beat up, clearly somebody has already tried to fix this thing. I pulled the water pressure release plug and it had corrosion on it, can be seen in the pictures. As I started to pack it back up to send back I got a good look at the packaging and though everything is for the most part it what appears to be a new condition, the bags look like they may have all been crumpled up at one point. Even the box it shipped in had two layers of tape, as well as the accessory box. I can’t speak for the previous purchaser of this unit but it was sent back and instead of its function being verified by the seller it was just shipped back out and I was the poor sucker that has to send it back again. Not impressed. I have read many good reviews but I’m not sure I want to give GasLand a second chance.

Why did it drop another star? Well, I've had to call customer service AGAIN. Now it has started making a horrible screeching noise when the water output temperature reaches 140 degrees (95 degrees input.) My speculation is that the safety shutoff that's supposed to engage at 167 degrees is partially engaging at 140 and is restricting water and gas flow. The moment I turn the gas down and the water temp drops to 120 the sound goes away. This may not sound like a big deal for showering, but I'm using it to heat a tub of water that I want to have at 105 degrees. If I turn down the gas then it takes longer. I shouldn't have to turn down the gas when it's still 27 degrees from shutoff temperature. If you want to know why I might have rated this a 2 or 3 then read on. Otherwise, skip the next four paragraphs and you'll get to the actual review (which is pretty good.) I usually like to start on a positive note with reviews but I want to explain the headline. This unit has a design flaw. I call it a design flaw because, 10 minutes into my conversation with technical support, the agent said to check something and said "We get a lot of calls that turn out to be this problem." The unit has a filter (pictured) that is in the "water inlet" portion of the unit. The agent said that sometimes the pressure pushes this filter out of place and blocks water flow. (As a side note. You see all that gunk all over the filter? NO idea where that came from. I've been running "clean" (from a garden hose" water through a 100 mesh filter since the first moment I used this thing. So was all of that on the filter straight from the factory?) The solution was that I had to do about 20 minutes of trouble shooting and THEN I had to take the face off the unit (which meant disconnecting the battery compartment) and I had to remove the water inlet pipe to get to this screen which (thankfully) had not turned the corner and gone further into the unit. If it had, then I would have been waiting for a replacement part which other reviews say can take weeks. As it happens, I'm not shy about disassembling things and my heater happened to be mounted 3 feet from my shed with all my tools. If I hadn't had the tools handy or was hesitant about taking the unit apart (or was just of the opinion that I should not have to in order to fix a design flaw) then I would have given a lower star review. *** ACTUAL REVIEW OF THE PRODUCT *** Installation and assembly : 3 stars. Pros: The product layout is pretty easy to understand. The hookups are well labeled so it's tough to mess up what goes where Cons: Understanding that everyone has their own intended use for this, there were still not enough adapters. I needed 1/2" input and output. I ended up spending $20 USD to convert their pipe/hose fittings to 1/2" hose barb. No template for hanging the unit. I greatly appreciate it when something that needs to be wall mounted comes with a printed sheet that has marks on it showing where you need to drill in order to mount it. Then you just slap that sheet up where you want the unit, drill through the paper at the indicated points, tear it off and you're done. Function/operation : 4.5 stars Pros: Super easy to use once set up. Only has two knobs (heat and water pressure) I don't know if I'm qualified to rate efficiency since I've only owned this one heater but I'll do it anyway. I am using this heater to heat 370 Gallons of water. At 60 Fahrenheit outside temperature, it raises the water temperature an average of 1 degree in three minutes. So to go from 65 to 105 takes about two hours. Unfortunately, my computer rebooted after an update and didn't save the notepad I had open calculating costs but at my current propane costs of $2.65 per gallon I believe I calculated it as costing me about $4 to run it for two hours (somewhere around 0.8 gallons of propane (3.36 pounds) per hour) Cons: The stupid design flaw that I noted at the beginning. If you skipped that part, there is a filter that can break loose and block the water inlet pipe. It's a known issue and it requires partial disassembly of the unit to fix it. If you're running this with a transfer/siphon pump then you should have an external water filter set up anyway. I can understand not having that if you're running it from a garden hose. I'll put this in as a function flaw. I just spent $300 plus tax for this thing...and I had to go buy two D cell batteries? Seriously, anything that costs me over $100 should have the batteries included. AND WHY D CELL? About ZERO people have/use D cell batteries these days. How about a slot for one or two rechargeable 18650 batteries? They have amazing capacity, low discharge rate when not in use, they're used in vapes so you can get them anywhere and they're super inexpensive online. All in all, I'm pleased so far with the exception of that filter. It broke loose after only 10 hours of use incidentally. As long as this thing doesn't have any other surprises then I'm good. Everything else in it is solid state so nothing should break loose. The only concern I have left is the igniter which is a not-too-uncommon issue reported in the reviews. * crossing fingers * Oh, and it was super quick to get through to customer service on the phone. The representative was not quite as knowledgeable as I would have liked about my specific unit but he quickly found someone to assist him and he was easy to understand and work with, giving step by step instructions.
