What an easy install to replace the latest of the many failed Bosch glass lined heaters I've had since 2007. It installs using standard 1/2" FIPT braided fittngs that made the replacement a breeze. After flushing the system it was turned on to medium heat and came up to 123 degrees within minutes. It's a great upgrade from the old Bosch type heaters that require dielectric connectors using hard copper lines.because of dissimaler metals. The all stainless heater does not need that addded install complexity. I'm looking forward to a longe service life created by the all stainless steel design.

.... That fits so nicely just under your sink inside your cupboards. The heating up of the water is almost instant and can be dispensed pretty much immediately. The only thing is is that it doesn't last as long as I would have hoped as far as the hot water goes. This can be used in your kitchen sink for extra hot water when washing dishes, or it can be added to a salon to provide a little more opportunity for hot water in case of a busy client day. It could be used for any number of purposes. And it works fantastic! The design is small convenient and sleek and modern. It looks very nice and is easy to install as well. We have not experienced any leaks so far, so we're quite pleased with its performance.

I installed this 2.5-gallon mini electric water heater under my kitchen sink, and it’s been a game changer for washing dishes. No more waiting for the main water heater to kick in, hot water is ready almost instantly. The size is compact, good looking design, Installation was pretty straightforward with clear instructions. I tested for few weeks now, it works great so far, I will mounted it on the wall later in order to keep the floor space free. The water gets hot quickly and stays hot long enough for light kitchen tasks. Great little upgrade for convenience and efficiency!

I’m really impressed with this mini water heater. Installation was straightforward and easy. The heating is very fast – we get hot water almost instantly, which is perfect for our bathroom sink. The compact design is a big plus. It fits perfectly under our sink without taking up much space and looks neat. Overall, it’s an efficient, space-saving solution for small bathrooms or kitchens. Highly recommend!

I received the item and I used it for a week. The item worked very well with hot water and did what it was supposed to do. The only problem with the item is the electrical plug to the item. Had gotten hot and melted.

The noise is so low that the running sound can hardly be felt. The appearance design is simple and generous, and the operation interface is also 2.5-gallon capacity, it delivers a surprising amount of hot water, more than enough f Or typical kitchen or bathroom point-of-use needs.

This is a small (2.5 gallon) water heater designed to fit under a sink or be used in a space where perhaps it's a long run from the water heater - ie to get hot water to that fixture sooner and save on water waste. Admittedly, it's a little small, but It's quite convenient that this doesn't need to be hardwired in at 220, but includes a 110 plug to plug into a typical outlet. For most people though, I suspect this still means they need to wire a new outlet to the spot they plan to place this. If you have a plug under your sink for a disposal for instance, it's generally recommended that plug serve only the disposal and this HWH have it's own plug on a separate circuit - though I do suspect a user could get away with plugging them both into the same without issue. This is an easy install; I'm running pex so it's a super easy hook up for the cold to the unit and then hot to the fixture above the unit. Water temperature is nice and hot with no issues. Energy efficiency is claimed to be good on the unit but frankly, I'm not really monitoring that in my household. For what this does, it's functionality is great. I am actually using this in an outbuilding that I keep above freezing in winter to have hot water in the sink in the building. I run that sink daily, so it's not just a random unused fixture. This came me a great value way to get hot water there. Quite happy with it.

This 2.5-gallon tankless electric water heater is exactly what I needed. It's small and fits in tight spaces. I put it under my bathroom sink. It heats water quickly and doesn't use much electricity.
