Sio Green SIO18 Electric Tankless Water Heater - Infrared Tank-Less Instant Hot Water Heater - Cost Effective & Corrosion-Free - No Lime Scale, No Algae, No Bacteria 220v - 240v / 80A / 18kW

I wasn't sure the water would be hot enough, WOW I love being wrong for once.lol. The location is a must though, in Florida. The cold inlet is nice and hot (around 75F and up) so water is hot. If your in Northern states I would have chosen a stronger unit (reading the zones to match your needs is a must)We have had no problems; shower always has hot water for everyone (one at a time). Yeah! As long as we don't run the dishwasher or laundry at the same time, no problem there, it beats waiting an hour between hot water needs.Using gate valve to calibrate the unit, I only adjust to 40C (104F) with flow rate output around 1.5 GPM, more than enough, no need to mix any cold valve at all, maybe just a little bit :D.I would recommend this if you have the small house, apt, condo that you want to use single faucet shower head one at a time if you have a minimum 70F cold inlet. If you have less than 70F cold inlet, I would recommend going with IR288 POU (8.8kW) or IR14K POU (14kW). Though, check your map sizing guide to determine your cold inlet, or use the temperature thermometer and measure your cold temperature and determine the range region you are in.

I had this IR260 unit for around a month before I was ready to install it. I had a little trepidation about whether it would provide enough warm water for my application (small cabin, 2 sinks, one shower) but forged ahead and had no issues with the installation process. Following the directions exactly, I turned the unit on and opened a sink faucet. To my delight, warm water soon came out. But the real test came when the shower hookup was complete and I went to try my first warm shower in the cabin. This time, I got even more warm, actually hot, water and had to turn the shower down towards cold a bit so it wouldn't be too hot. This unit is perfect for a small cabin or home with just one or two people using hot water. The unit takes up so little space and I found it nearly a snap to install. If you get one of these, make sure you turn the faucet hot water handle all the way on until the temp stabilizes before backing it off. If you turn it on just a little, you'll get a "beep beep" from the unit indicating that there is a "flow restriction error" - what this means is there is not enough water flowing through the unit. A leak anywhere in the system will cause this error to show as well - I found this out from having a screw cap at the end of the hot water line; the male adapter threads had no teflon tape on them so it leaked, hence the "beep beep".On standby, the unit shows a "4" where the temperature usually is displayed - it would have been nice to know this beforehand as it is nowhere in the literature that came with the unit. At first I was wondering what kind of problem or error this might be. Perhaps a less confusing display for standby mode would have been "SB" and including this in the manual or instructions would have cleared everything up anyway.

We installed the unit in our homeowners club house that only has one faucet needing hot water. It really does the trick perfectly. It provides nearly instant hot water for the few times we need it a day, and we do not have to continuously heat a tank of water. It is the perfect solution. It was easy to install and worked immediately.

Woow I %100 love it the cellar thay are amazing I have received a damaged unit in shipping process 3 days later it had a new one to install thank you so much you guys are the greatest.As far as the unit itself it is so easy to install plenty of hot water and is so nice to look at very well put together product I would recommend it to anyone living in Oklahoma I'm on well water thats coming out at around 56 degrees I have plenty of hot water hot enough that I have to mix it with cold water so I can wash my hands wow!!!

Living in Arizona for the winter makes a tankless more users friendly. The ground water is so much warmer than the rest of the country. For what ever reason the previous owner had a 50 gallon hot water heater in the Arizona room that had a shower, sink and washer. I wanted to replace it but I didn't want to redo the wiring. The tank had a 2 pole 30 amp breaker, I looked at most of the tankless heaters on the market and decided this would work. Received it in a couple of days, installed myself and it works better than I thought it would. Once you figure out the water hoses you need (flex faucet hoses) and get the metering set right, it runs the shower for as long as you want hot water. Works great in Arizona, check the temperature of the water coming into your house.

Love this water heater! Like it so much that id like to sell them to everyone. Its not big enough to do a whole house but its plenty good enough for running area if all water areas are close together. I have it heating water going to my poolhouse 20 feet away and can even take hot showers out there. I plan on running a solar water heater before it to preheat water to make it even more efficient.

Excellent unit, simple to install and quite efficient. Because of my power limitations i had to get this model, has few limitations vs IR14K or IR8000 however i love it. Provide enough 1 shower at a time for me (live in Hawaii), i have to dial gatevale down a bit because it was too hot. Also, it was so inexpensive compared to replacing my water heater tank. Now I have a very large pantry were the tank use to be and this IR260 is in the top of my linen closet.
