    Awesome product

    Great little unit for the price Works amazing I did have to install a valve on the outlet side to slow the flow a little to get the right temperature (slowing the inlet side didn't work as good) so it cut my pressure down a little on the hot side but works pretty great for a full bath, laundry, and dishwasher just don't run them all at once on hot. You may be able to run two of them in series and be fine or get a smaller one and preheat the water before it hits unit , but I would most definitely buy again.

    Nice unit, works well so far.

    Nicely made unit. Clean lines, nice display, lightweight, easy to mount. You'll need a terminal box to wire it up since it comes with it's own pigtail cable (they don't want you to open up the case since it will void it's warranty, apparently; multi breaker units might be different), so I bought an inexpensive 60 amp A/C unit type cut-off switch box with a pull out switch. Just mount it near the heater on the wall and run your 6 gauge wire to it from your breaker panel. I just wish they had included adapters so that you can plumb it to 3/4" piping, so you'll have to buy your own if you wish to connect it to your existing 3/4" pipe. I had trouble using pipe dope (maybe it was too old or the wrong kind?), so I switched to Teflon tape (5 layers) on each fitting and that did the ...

    Great for single water efficient Shower or single faucet

    Ideal for a small flat with one water saver shower head and one or two faucets but you can only use one outlets at a time. Ive installed this under sink. I have a Rheem 18kw for the shower But in a pinch it would work in Sydney as imput water temputure rarely gets below 55F or 12 degress C Any colder part of Australia. You might be having warm showers with hot water tap at 50% and cold tap off Set your expections at no more than `1.75 Gallons/6.65L per miniute and you should be fine

    Great Product

    Once you set the water temp. it is constant!! I also recommend a 2 year warranty.......I have no experience on how long they will last, but my feeling is, the should last for years without trouble! I set it up for the whole house, but its best not to use more than one fixture at a time.... I think for large households, more than one could be installed.....
