We are now onto our second one of these, first one replaced under warranty.

Second one has been fine until over Easter. I had a shower, turned it off. Then the GLW hopped in, I turned it on and it wouldn't work. Plenty of gas, battery fully charged, but still no go. Swapped from gas bottle to canister still nothing.

I've given up on the bloody things. Temperemental, fiddly and inconsistent.

We're going back to a simple bucket of warm water using a kettle.

Thanks Jim, you have saved me some money.

I have been trying to justify the investment although herself is not too interested, but on reading your comment, I too will stick with the kettle for heating.

I have got a great life so far out of the $30 Coleman battery operated imersion shower.

Smart move Bill.

Even when they are working "properly" they are fiddly. If the water they are drawing has been in the sun you have to turn it down so low that it blows out in the slightest breeze.

Getting the water "right" takes time and varies according to the temperature of the input water. So, a given setting does not produce the same temp each time. After adjusting the knob (and it has to be done in miniscule increments) you need to wait about 30 seconds for that water to flow through, and then adjust again as necessary.

More junk to set up and pack away.

I'm going through a "de-gadgeting" phase in my life.

G'day Jim,

If you have a squiz on the Australian CamperTrailer website you can see under tech tips the hot water system I set up. Used it for the first time in the field so to speak over easter and it worked brilliantly. Uses about 7 litres of water per shower. No fiddling around with it. Just plugged the power lead into my 12v outlet on the trailer and off it went. Operates from inside the shower tent using a stop valve on the water line.

Nothing like climbing into a hot shower on those crisp mornings up in the high country.

I bought one of these units as well, it worked great just out of the box. Then we actually wanted to use it, some spark then no pump. Sure flat battery but it wouldn't even run on it's power supply. So back in the box and gave it back to Kmart couldn't be bothered with it either.

Buuuuut me mate over the road has had his for years and works like it should, battery stays charged hot water on demand.

But his wasn't made in Chine like mine was.

Anyway back to your problem.. maybe run some CLR through the pump and clean it out a bit. The scale build up might be causing the heating problems.

Ours is now somewhere around 4.5 / 5 yrs old , no problems , removed spring under knob years ago ,makes temp adjusting easier , fully drain all water if storing unit for more than a week and clean filter ,,, have run a weak solution of CLR through the unit on the odd occasion after using bore water or unclear river/creek waters ,,,

I'm curious as to why people would opt to go a Coleman style of water heater when there's a style that operates off the car motor?

Personally up to this point we have gone the water boiled on the stove and the APC style of wash. Less hassle, cheap as chips and works everytime.

Axel - Isn't there benefits to the underbonnet units too? Such as weight saving.

Also I can't even begin to imagine my missus wanting to shower if I'm off collecting firewood. Someone has to stand guard.

Ive seen both the Primus and the Coleman and to me they just seem way too bulky for what they offer. That's why I'm wondering if the under the bonnet jobby isn't a better option.

Have hammered my Coleman heavily over the past two years....never had a problem.....apart from one gas cylinder that had some oil in the gas (dont know how but when I opened the cylinder to the air it would spit until it cleared)...then all was good again.

Best to use it to heat a bucket of water, then turn gas off when temp is right. Takes about two minutes tops.

Works well this way.

Camper trailer has built in hot water, so use this often, but when camping without the trailer, the Coleman is never left at home.

Top little self sufficient unit.
