Stiebel Eltron SHC 2.5 Mini-Tank Electric Water Heater, 2.5 Gallon

1 Year reviewWe purchased this 2.5 gallons WH for our kitchen sink and dishwasher as our home was plumbed in a way that the kitchen sink is a farthest point from our 50 gallon WH. To run a kitchen sink or dishwasher, it requires significant amount of wasted water to be flushed down the drain, not to mention heat loss in pipes (this is why a recirculating pump is a no go for this fixture). We choose 2.5G simply because its the biggest one could fit in an under sink cabinet. We also connected it to a 15AMP outlet with wireless switch rated at 1850Watt consumption. I tapped into a COLD water instead of hot, as I don’t want to draw all that water from a big one and waste water I can use for a shower or laundry. You definitely can connect it to a hot side, but it works flawlessly on cold one too. Beware that there will be a recharge of about 15-18 minutes if you depleted whole WH, but recovery gets you a nice warm water even after couple of minutes. It’ll not happen on a hot side, since water will get up to a temperature before your little tank was depleted. But again, you most probably will experience what called “a temperature sandwich”. When choosing the right size tank, be aware that there’s pressure relief valve sticking 2-3” on top. Make sure you install a drain for this valve and route it outside. We set the tank at very high setting to keep as much hot water possible to mix with cold water at the sink. We also run it only for when we need it, before turning dishwasher or cooking, which saves huge amount of wasted energy and money. Overall we are very happy with this one, no more waiting for hot water, wasting energy and water. I suggest to install them at any fixture that far from your whole house WH. I also recommend to get a under sink pan and water leak detector (ring is the best I could find so far) in case you have a leak.

Ive had this water unit in my RV now for a few weeks and am very happy with it. So much so, i bought my sone the 6 gallon unit. They are well made and work great. The installation was easy on both of them. A solid purchase.

Excelente calidad de calentador, lo recomiendo mucho. Lo uso para un lavabo y quedó super bien. La potencia ideal.

I have this installed in my dog grooming van. The unit is powered by a twist timer, and I it fully heats in about 20 min.. The full hot temp is too hot, so I lowered the setting. To those who want really hot water, this unit is a winner. Also, adjusting the thermostat is easy and on the front of the unit, one doesn't have to go digging into the guts to adjust it. It's been in the back of my van for almost a year without any leaks, and I assume it would be invincible if it were parked in the safety of a home bathroom. I also like that it only uses 11 amps or so; it doesn't max out the wiring or the circuit breaker to make the ultra hot water. It is much slimmer than the Bosch unit, and the Steibel website says that it is made in the US or Germany and not China like the Bosch. I do want to write the company for assurance on this, but it would only provide peace of mind for future use as its already installed and works flawlessly for the present. I am glad I bought it!

Easy to install and use. Probably would have gotten the larger one in retrospect though. Have no long term experience to comment on, but so far so good.
