  • Like it, does the job, has some install quirks
I like it, gets the water hot, and got it scratch and dent so nice and cheap. Mainly here to give some info on this. So this is actually in metric, that's why you can't find vent parts, it is actually a 60mm vent. Searching "60mm wall thimble” will get you the camplux branded wall thimble for this. All 3 fittings are 1/2" BSP (BSPP technically but is usually called out as BSP) threads and you will need a BSP to NPT adapter. BSP doesn't seal on the thread, it will need a gasket (unit comes with these) inside the adapter to seal, use a water based lubricant (yes 'that' lubricant will work;) ) on the gasket to aid in sealing and preventing damage to the gasket. I would suggest puting one wrap of teflon on the thread just to aid in tightening, but it will not contribute to sealing. I also noted that the required natural gas pressure (6-8w.c.) was a bit above what is supplied at my house (5.5w.c.), thankfully i was able to get the regulator adjusted (don't forget to check your other appliances minimum and maximum gas pressures before doing this). Tech support is extremely responsive (I would get results in 10 minutes) so that was really nice! Oh, it also seems it no longer has the 10-20min auto-shutdown timer. I can not find any new documentation referencing it and I definitely have been taking 20min+ showers! (There's some very old sources stating that it does, glad they got rid of that) ... show more

  • Great product for the price
Bought this as a cheap alternative to replace failed tank heater. Was not sure what to expect for such a low cost heater but after 2 months of use, have been quite pleasently suprised. Instalation was fairly straight forward with the exception of needing to plug in, which I fortunately had nearby recertacle. Water and gas lines hook on with common fittings. I did put a T&P valve in the water line along with gas pressure regulator (recomended/required by most codes) which are not included. Venting will depend on your paticular installation. I was able to install with the included vent pipe but may require additional vent pipe depending on your paticular needs. As this is a base/entry level model, temp. control is basic and takes some patience. Maual does not explain how to set very well which is why tech support got 3 stars. Was able to figure out on my own but no one should have to waste a lot of time on phone to get info on setup that should be in manual. Overall, has performed well over last couple of months. As it is a smaller unit, best suited for anyone who does not have high demand for hot water, as will not run multiple faucets at one time. Great for small home, garage, camper etc.. or installed as point of use such as shower, as it will deliver continuous hot water. ... show more

  • doesn't work with low-flow faucets
I have been fighting this thing for almost a year now. In California with the low-flow requirements, it doesn't flow enough to 'activate' the water heater. I have taken apart 2 of the faucets and was able to drill them out to flow enough to make it work, but still can't get hot water out of my kitchen faucet because it doesn't flow enough. Pretty frustrated ... show more

  • Tankless water heater for the tiny house
This is a quality unit that is easy to install. We used it in a 420 sqft little house it handles the kitchen bathroom and the washing machine with no trouble. It does take a minute to get comfortable with the adjustments, but it was pretty easy.
