Questions & Answers

Can I use it for the shower if it's just for one person

Asked by: Tito
I use it for a shower and small washing machine, but not at the same time. When combined with the cold water for a warm shower, I can use a low flow (1.5GPM) showerhead and have about an 8-10 minute shower.

I will be using this in my camper/travel trailer. I do have a sink and can put it in the cabinet under the sink. My primary interest is short showers. The shower head is attached to a tube which is attached to a tube coming from the sink, like the sprayer on a kitchen sink. Actually, that is what the shower currently is. Anyway, would this work to get hot water to the sink and shower? Thank you
Asked by: Mishy
It will, as long as there is a hot water pipe to plumb it to. If you only have one pipe then you will need someway of mixing your hot and cold water.

Currently have a 30 gallon, hard-wired tank that only feeds the kitchen sink and dishwasher. Thinking of the Bosch Mini-tank as a replacement. Would it be sufficient for this use? Also, how much noise does the unit produce?
Asked by: Diane
I bought my 4 gallon for exactly this purpose. It is piped to the kitchen sink, where it is used mostly to hose down dirty dishes via a foot operated valve (Chicago - would not be without this accessory!) with a side branch to a brand new Bosch dishwasher. We have never had a problem - 'works like a charm and as the tank is located in my workshop below the kitchen, I couldn't hear anything even if it did make a noise - which it doesn't.

We installed 1 of these plus 4 2.5 gallon units, and had the following discoveries: do NOT use regular NPT fittings with PTFE tape. We tried on all 5, and only 1 had no issues with leaks on either port. Somehow, the threads are either cut large (less taper than standard NPT so starting diameter is off), has a poor lead-in (can only get 1-2 turns by hand before it binds up), or the material is wrong (keep getting chips and dusting from brand new units), but either way, our best success was using fittings that have a rubber interface (o-ring or conical washer) to seal to the tube we are connecting to. Everything else would leak to a greater or lesser extent. I would hope Bosch would figure out the reason for the binding up and/or the poor integration with off-the-shelf valves and fittings, but we wasted many brand new fittings (the removed fittings had marring on the threads) and many man-hours trying to keep the installed system from leaking.

Rated 4 out of 5 by from Our water heater is at one end of the house... Our water heater is at one end of the house and our bathroom is at the other end. That means we had to run our hot water for over a minute before we got any hot water. So I decided to install the Bosch 4 gallon hot water heater and put it inline with our existing hot water heater. This has the effect of extending the range of the hot water heater. The install was a snap, no issues at all. After I plugged it in, I waited a bit and tested it out. The water in the bathroom got hot within 10 seconds which is a great improvement. The only issue, and it is a minor issue, is I had to turn the dial up all the way to get the hot water warm enough, this is the only reason I didn't give it an excellent rating.

Rated 5 out of 5 by from My kitchen is a long distance from the water heater.... My kitchen is a long distance from the water heater. I would waste about 3 gallons of water waiting for it to get just warm, not hot just warm. I installed this Bosch 4 gallon electric water heater under the kitchen sink and now I have instant hot water. No more waiting and wasting water. Note, when I installed it I ran the hot water line from the house to the cold water side of the water heater then hooked the hot water line of the sink to the hot water side of the water heater. This way when I use the hot water I am now feeding the Bosch water heater with hot water. This way you never run out of hot water and you never over work the little water heater. I hope this helps you.

I replaced a traditional style, round, 2.5 gallon, steel water heater, which was leaking because of tank rust, with this 4 gallon model. Obviously, the larger tank provides more hot water than the old heater, but the difference is greater than I anticipated. Two months since installation, my wife is quite pleased with this one. She hand washes the dishes, and has hot water to spare, after each wash. This tank is the primary source of hot water for the kitchen sink, as the previous homeowner completely removed the hot water supply line to the main water heater. Even so, the Bosch Mini-Tank is able to provide plenty of hot water for our family of five's needs, both for cleaning dishes and for hand washing. This unit is reasonably easy to install; even for those with little to no plumbing experience. Consult your local Home Depot "master plumber" for advice and for the proper installation materials.
