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

Asked by: Tito
Many customers find this to be satisfactory for a shower. Your expectations for shower time duration will need to be measured in relation to experiences with full size tanks. You can extend your shower duration by adjusting your cold/hot mix and setting the unit to its maximum heating setting. Due to the mix of hot/cold in shower use, you do get much more than 4 gal of water for your shower and the unit does heat while hot water is being depleted - which will provide more than only the initial 4 gal of hot water. How much more is dependent on your heating set point, flow rate, and hot/cold mix ratio.

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 now have hot water almost as soon as the tap is opened. If you have flexible sink connections from shut off valves, it's a fairly easy install for the experienced DIY. It takes up a lot of room under the sink so measure twice before you buy. Keep in mind the pressure relief valve requires a place to discharge!
