We wanted to boost the hot water to our kitchen sink. It is the furthest point in the house from the Water Heater in our 4,000 sq/ft home. So tired of cold water and waiting over a minute or two for hot water. With dishwasher hoses from our local Home Depot, we attached the Hot water line from under our sink into the water heater and the Hot water from this mini 4.0 gal heater directly to our kitchen sink faucet. We love this product. We went with the bigger water tank, so we placed it in the cabinet to the side of our undersink cabinet. I used a doorknob drill bit to access the area under the sink from the adjoining cabinet. Total install was about 25-minutes. Seriously. Great Product, easy to install, instant satisfaction.
Easy to install, used cpvc for new plumbing connections. 220V was easy to connect for me but you may want to hire an electrician. This unit gets the water nice and hot. The GPM is not enough for me, I should have gone with a more expensive 2 coil unit with more GPM. After 5 miutes or so the coil shuts off and then comes back on, get some cooler water until it kicks back on, sometimes I shut off the water and turn it right back on which restes the flow switch and turns on the coil, instant hot.
The unit does not lend itself well to installation. The electrical conection entrance is not good. The unit itself is okay, but is easily overwhelmed. I only use it for hand washing and small amounts of water in the sink in the shop. So, it is okay. However, I have a hose connection to outside for pet washing, etc. The unit cannot keep up with the flow.
