Thread: Instant water heater.

I have a Rennai unit that is powered by a single C cell battery. I have it set up on a frame made out of light weigh 1" galv box section. There is a piece of ply screwed to the frame and the heater is fixed to one side, and on the other side is the 12v pump and accumulator. I have a bypass system on it so you can plumb it straight into a garden hose if pressured water is available. This unit is about 20 years old now and is now due for its first service as its getting a bit temperamental on the temperature adjustment and trips out on the highest temp setting.
Mines rated somewhere between 10 and 15 L/min from memory. Someone's loaned it till the end of the week to go hunting so I cannot tell you the model number.
It puts out just enough water to have a hot shower if you use a low volume shower head (I have found that the best shower head is either a dog wash head or one of the old type that you used to push over the hot/cold tap in the bath using the rubber cups), and you can crank it up to max temp/min flow and get about 60deg water out of it for the dishes.

When mine returns I'll try to remember to post some photos and the model number.
