I bought an under sink tankless water heater because in our house the hot water heater is about 75 feet from the kitchen sink. I hired a licensed plumber to do the plumbing (primarily because I HATE working under sinks). There are two valves for each supply (2 for hot and 2 for cold - one above the other). The plumber said it didn’t matter which one I connected to. I want the tankless heater to handle both the sink and the dishwasher. I bought a Bosch unit because I like their products and it was advertised as pluggable. I assumed that meant 110V pluggable - bad assumption. When I began installing it I noticed that it was designed for 220V. So- I returned it and bought another one, making sure that it was 110. I’ve now been under the sink twice.
As I was installing the second heater, I couldn’t get any leverage to screw in the screws to hold it because of the cramped quarters. So, I went out the my shed and got my cordless drill and drilled a tiny pilot hole. Just as I completed the hole, the battery died and I couldn’t get the drill out because of the cramped quarters. So, I carefully pulled the batter out, went into the shed and got a new one, and brought it to the kitchen. However, as I was inserting the battery into the drill, I broke the bit, so I had to go out to the shed and get some vice-grips to remove the drill bit. I’ve now been under the sink 6 times.
When I connected the new heater, I didn’t get any hot water out of it. I had already installed a 40 amp circuit breaker and I know that the under sink heater has power because I checked it. I also noticed that it now takes a LOT longer to get hot water at the sink from the original hot water tank. I also felt the outlet line from the under sink heater and it feels cold.
So, I returned the heater and purchased a new one assuming it was defective. I’ve now been under the sink 7 times.
I got the new heater, installed it and plugged it in to an outlet that has power. But, I’ve Still got no hot water at the tap even after my 8th time under the sink. I’m beginning to think that connecting the outlet of the heater to the tap under the sink is a bad idea. By the way, as I was getting my head out from under the sink, I banged my head and now have a bloody forehead.
The plumber put a Tee connector at the upper tap with one line going to the sink and the other line going to the dishwasher. Somehow, that doesn’t seem right to me. I’m going to take the outlet line from the heater and put the tee on that line and just close both taps on the hot water side.
Now - I’ve got three questions, One, do any of you like working under sinks in cramped quarters? (I assume the answer to that is no.) Two, have you had a good laugh from my experience (or at least a good chuckle)? I hope the answer to that is yes. And three, do you see any issue with my proposed solution?
P.S. I still hate working under sinks!
