  • Great water heater
Style: 8L
Welded mounting brackets to a dolly and now have this unit and propane tank all together and mobile. Works great. I use it for washing the dog. The heater has a great flow rate and is able it heat the water very good. So easy to use, all I do is hook the water hose on and open the propane and its ready to go. ... show more

  • DIYer’s outdoor Soaker Hot Tub in Fairbanks Alaska, April to December.
Style: 12L
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. ... show more

  • They work well and are a great value for the price.
Style: 8L
It puts out a lot more hot water than my other Gasland heater. It is a bit hard to adjust the water flow and heat to get it to ignite every time.

  • Very good water heater - a bit hard to store away when not in use
We've used the Camp Chef Triton 5L heater for years, loved it (until I let it freeze). They're no longer made, so I needed an alternate water heater for our off-grid property. This Gasland unit is a good replacement. It's not too hard to set up (see caveat below), and it works -- we've only used it for a few days, but so far, so good. HOWEVER...there is one "feature" which I do not appreciate. It's a bit hard to describe, so please bear with me -- the problem is a brass fitting which is used to connect your hose to the water inlet. In the Triton heater, this fitting was made up of two components one of which attached to the hose, the other to the heater's water inlet - one piece rotated freely within the other. After attaching the smaller piece to the heater, you inserted a rubber washer into the other piece, and could then TURN THE LARGER PIECE TO CONNECT THE HOSE WITHOUT TURNING THE SMALLER PIECE. Simple concept, right? Unfortunately, Gasland somehow failed to grasp the perfection of this concept. Their fitting is a SINGLE brass connector with threads at each end. No matter how you try to attach the hose, you're SCREWED (pun intended). If you attach the fitting to the heater, you can't then turn it to attach it to the hose without unscrewing it from the heater. If you attach it to the hose, you can't then turn it to attach it to the heater without unscrewing it from the hose. CATCH 22! So how did I resolve the issue? First I disconnected the gas and water outlet (spray head) I then attached the #%@& fitting tightly to the hose. I then twisted the whole hose about one full rotation to allow me to start the fitting onto the water heater, for one thread. THEN I TURNED THE ENTIRE WATER HEATER AROUND AND AROUND AND AROUND to screw it onto the fitting until it was almost tight, and used wrenches for the last quarter turn. It left the hose slightly twisted, but it's working. The only other VERY SMALL negative -- when not in use, we can't leave any water heater unprotected outside where we use it, we don't want to subject it to rain and dust and pollen. It needs to be covered. I built a "dog-house" from plywood, which fitted nicely over the propane tank and our old Triton heater, which stood on legs on the ground. Unfortunately, although it's easy to pull the Gasland heater off the bolt from which it hangs, you can't just set it on the ground, as it has no legs -- the water and gas hoses get in the way. It has to be laid on its side, where it takes up to much acreage to fit in my dog-house. #&*@!$$! Oh, well. [sigh] I'll build a better dog-house. All in all, this is a VERY good water heater...so far. Stay tuned, film at 11. ... show more
