Question: would this unit work for an rv shower?
Document: This unit is not much more capable of heating a cup of coffee. STIR CLEAR OF THIS ONE and go for the 220 volt models. Work much better.
Bought this water for a very small half bath. Works well in sink area, but I do not think I would use it of shower, I don't think you will be able to get enouth hot water flow. Over all I think it is a good product.
I had read a lot of reviews and product descriptions. I thought this one would get my shower started with hot water and then the big water heater would take over, however, this one is so small, it does not give me the hot water I need for a shower; the agent said this was more for handwashing than showering so I am disappointed. should have read the directions better.
Unless you have a 240V outlet already installed and available, consider the cost of the unit and the cost of the installation guy if you can't DIY.
I have used this for 9 years to heat hot water in a small vacation rental apartment. It just stopped working and may buy another one. It gave hot water for the shower and bath sink and kitchen sink. The apartments accomodatesup to 4 people. We are near the beach so people take lost of showers.
Took forever for the hot water to get from the garage to the kitchen sink. My hubby installed this as a supplement to the hot water and now, almost instant hot water and it is HOT!, just the way I want it. Perfect for washing those greasy dishes. And since we don't have to wait for hot water, we don't waste as much anymore.BTW, did a lot of research before I bought this unit.
This would be handy for a one use service area such as a sink, just too small for our needs. Small and compact,
I thought it would be for having instant hot water. It works ok if you keep the flow low and slow, but I would have thought it would get the water HOT and then adjust to a safe setting.Instead I am adjusting it to get the most warmth out of it, and its not easy.
I hardly ever generate enough dirty dishes to run my dishwasher. Therefore, if the dishes don't get washed immediately after use, they tend to pile up until I lose my mind. Also, my kitchen sink is the exact opposite end of the house so it would take FOREVER to get water hot enough to wash my dishes and I hate wasting water. To make sure I had quick access to hot water to do my dishes this was the choice I made after A LOT of research.
If you have a regular old kitchen faucet the hot water is going to be instantaneous. The water is not as hot as what you'll get out of your house water heater but it's perfectly fine for washing dishes and washing hands on cold days.I think this is your best bet for a single sink use if you don't have access to 220.
Answer: yes
