  • DIYer’s outdoor Soaker Hot Tub in Fairbanks Alaska, April to December.
Style: 3.18 GPM/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

  • Easy to set up and VERY hot water!
Style: 1.58 GPM/6L
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. ... show more

  • Beware of using hard water
Style: 1.58 GPM/6L
Works as expected. Beware of running hard water through it on a regular basis, it will booger up the system and it stops working.

  • I give up.
Style: 1.32 GPM/5L with Pump Set
This is the second propane shower from Amazon that failed to work. I ordered a different brand previously that had a faulty gas inlet valve and would keep the temperatures too hot to use (between 120 to 150 degrees). Amazon did give me a refund so I looked at the reviews and ordered a Gasland brand, thinking it would be better. The box stayed in my house for over a month until I decided to install it today. Surprise, surprise. This one doesn't work either. I could hear clicking from the igniters but the flame never lit. The water flow seemed adequate but I installed a second booster pump anyway to increase the water pressure. That didn't work. I opened the cover and verified that the water flow switch was closing and working properly, suggesting there was sufficient water pressure and flow to start. Only 1 igniter of 3 was working so I re-gapped them and eventually got a second one working. The third igniter was missing the soldered ground tab to the body, so there was no way to get it to work. I noticed there was no gas smell when the igniters sparked. I thought maybe it was the gas regulator on the propane bottle so I replaced the one included with the shower with another one. I tried a different 20 lb propane bottle also. No gas came out. I finally realized the electrically-operated gas valve was not opening and not allowing gas to enter the combustion chamber. The gas valve is supposed to open once the water flow switch detects sufficient water flow but it isn't working. I give up. I waited past the return window to install it so I lost my money. I have been hoping to use the shower for an off-grid location. I had less trouble heating water on a stove and pouring it into a shower bucket. If I eventually manage to get the unit working, I will edit my review with updated findings. My recommendation to manufacturers is to include an LED light that shows low water flow, thereby assisting with the diagnosis. It would also help to add an LED light that shows low gas pressure. The right side of the cover needs a label showing the proper orientation of the D sized batteries. Above all, please make sure the unit works before it leaves the factory! Edit: After inspection, I finally found the cause of the failure of the gas solenoid valve. It seems someone at the factory tried to press together one of the electrical connectors backwards. When I pulled the wires on the connector, it came apart easier than I expected. I turned one of the connections 180 degrees and re-inserted and the gas ignited. Now I have a new problem. The gas igniters only fires if I turn the water flow dial to halfway. I am assuming that turning down the water dial increases the outlet was pressure enough to turn the water pressure switch on. Using the water flow dial reduced to halfway on keeps the water flow too low and the temperature too hot to use the shower. I would suggest the manufacturers might switch from a water pressure-detecting switch to a water flow-detecting switch. ... show more
