5.0 out of 5 stars Correcting the product description..., February 19, 2010

This unit HAS to have a low flow in order for the heating capacity not to be exceeded by the requirements of the water flow. Water requires alot of energy input to change it's temp, and the colder it comes out of the ground, the lower the maximum output temp will be at a given flow rate... thus they limit the maximum flow rate so that it will work in places where the water does not come out of the ground at 60+ degrees as it likely does in most of Brazil.

Brazilians may be used to 0.88 gallon per minute showers, but people in the US may be dissappointed, based on what they're used to.

They should mention this more prominently in the Product Description, which, overall is hard to decipher due to all caps in sections, and a total lack of paragraph separation...

The other thing that should be prominently and correctly identified is that this device, though it is 110 volts, would not be safe to plug into a common 110/120 volt household or commercial grade receptacle. For a safe installation, it requires minimum 10 gauge wiring, and a 30 amp breaker, as 25 amps is not a common breaker size here.

Additionally, wire is not commonly sold with an amperage rating... Wire size is dictated by code according to the breaker amperage, which must match or exceed the amperage requirement of the device... which in this case is 25 amps, so 30 is the next step up in common breaker sizes.

Originally, I gave this product a good review and 4 stars, not long after I bought this shower head water heater. However, it's been a year, and when I went to use it this year, I found the thing had burned through and had to be thrown out.

Here's some of what I said originally: I've traveled a lot in the 3rd world and stayed in homes that have no hot water heater - except for a little electric shower head that takes the chill off the water.

I wanted an outdoor shower for the summer months, and tried to find such a device at my local hardware stores. No luck. I searched online and found the Coral device, made in Brazil. It was offered in 110 and 220v. Easiest for me was 110 version. BUT you will need a 30-amp circuit to tie it into. Some reviewers say this product just doesn't work: I'm betting they tried to wire it into a 15 amp circuit. It'll trip it every time.

I tied this into my jet-tub circuit, and it actually cost me more for 30 amp wire ($1.50/ft at Home Depot) than it did for the device! I hooked up a garden hose to plastic pipe, to a metal shelf mount that brought it out where I wanted, and screwed on the coral shower head (standard half-inch mount).

I turned on the water and the shower flow heated up. Great! As planned. (Some have complained that the water flow is low volume. True enough! Look at the size of the tiny heater!).

It's only really hot enough where I live to use an outside shower a couple of the months of the summer. So I used it a lot last year, then shut it off for the winter.

But this summer when I went to use it again, the thing didn't work. I took a close look and found a hole burned right through the plastic! I turned off the power, uninstalled it, and took it apart. The inside electronics are cheap, poor quality. And the device actually runs current through water! I remembered that when I put my hand into the water flow, close to the head, I could feel an electrical tingle! Not safe, in my opinion.

It's just a plastic exterior with cheap electronic parts. While the price is only $35 - not going to break the bank - I only got a two months of good use - but then it broke for good.

Unfortunately, I can't recommend it.

3.0 out of 5 stars Incorrect and dangerous electrical recommendation, July 20, 2010

This unit must be installed with GFCI protection. Ground Fault interrupters will shut power off in the event of a short, which could save someone's life. Electrical codes already require GFCI protection for all circuits in bathrooms, kitchens and garages.

Also before installing it make sure it has be certified by a Nationally Recognized Testing Lab (NRTL) such as UL or CSAus. Testing labs certify that products are safe to use and given the fact this product uses and mixes water and electricity I would not use it without an independent approval.

Also, In the United States, the national electric code (NEC) states any circuit breaker can only be loaded to 80% of it's rated capacity. This means a 30 amp breaker can only be loaded to 24A. This unit pulls 25A which if installed on a 30A breaker is in violation of NEC requirements. As crazy as it sounds, this unit should actually be installed on a 40A breaker and have the appropriate size wire running to it.
