Coleman HWS Shower, short hose.

Submitted: Friday, Dec 09, 2005 at 20:59

Jimbo

Paid $20 (OK, $15 on special) for the Coleman Shower Head and hose.

It's fitted with 1.2 metres of overly thick 8mm hose that is simply too short and inflexible. I whipped into a hardware store today and bought 3 metres of 8mm hose that is far more pliable for $3. It took about a minute and a half to fit.

I'm buggered if I can understand why Coleman would fit such a short length of high pressure hose (at a cost), when a longer piece of softer hose ( at less cost) would do a better job. Afterall, pressure is not an issue: we are talking about a bit of hose that can handle 3.8 litres per minute.

Jim.

dunno about the attachment value but recommend you don't go with the pump and go to a caravan store and buy the $70 unit that attaches to that hose. taking it out of the context of occasional 4wd'ing i invested in a supercheap style shower unit and pump and after consecutive burnouts because was using during housing renovations i invested in the caravan industry centrifugal italan made pump and after 3 years it is still going strong and substitutes for the $300 football field pump to line our field in emergencies.

Hey Jim,

Coleman have just released new stock of these and have extended it to a much better length. The old one was useless.

Cheers, ToNy!

Don't forget that water flow is affected by wall friction in the hose, extending the hose will slow down the flow.
I have the standard hose, put the HWS on a stove stand beside the shower tent & find the length to be ample.

on a side note - yes longer hose equals more friction loss.

But i can tell you the jaycar 12v shower units will pump hapilly through double the length of hose they come with , plus a set of quick release brass couplings and a custom heat exchanger unit. I was worried that my new set-up mightnt work as well, but it pumps just as much flow as standard :-)) And heats a 60 lt tub of water from 5 odd degrees to 'bugger me' hot in about 5 minutes.

Careful Bradley, you're dangerously close to violating the "You get what you pay for" mantra so often repeated and blindly followed on this forum :)))))

Hmmmm ... may have to think a bit more about my stock Jaycar unit.

HI Bradley, Your setup may depend on what type of Exchanger, a shell /tube has NO resistance to flow unlike trying to push it through a coil exchanger. Also like someone here mentioned the head height is the killer. Also your system is only sucking cold water through the pump, that helps the cheaper pumps. Michael

gramps - LOL :-)) not wrong there.....

Michael, yeah head height is the killer for any type of pump, but i'm only 6foot2 :-)

my heat exchanger is a coiled 10mm tube which would be at least 2.5-3 meters long if unwound, in a steel frame custom made to go on top of my gas ring, and the pump recirculates the hot water, no problems.

no argument a bilge pump or sureflow would be far superior, but this works grouse for me.

We recenlty went camping with friends on Stradbroke Island. Our Supercheap shower was on its second trip... didn't work. The pump had siezed up, due I guesss to water leaking in to it during our first trip. Our friends had brought along thier new Coleman unit.... was great except the short hose meant that the unit stood on a stand outside the shower tent and we had a "shower meister" who "drove" the Coleman unit according to instructions from the "showeree" nside the tent. It did make we wonder what Coleman were thinking when they designed the unit.

The longer hose option seems a great idea. Might invest in a Coleman st-up myself with an extended hose. They certainly work well.

Cheers

Jimbo, I had little problem just sitting the pump and unit on a table next to where I was showering and it gave a better water flow too as it didn't have to lift as far. Then I am only a little guy ;-)

Hope you and Jenny are well there.......
Cheers,

The length of the hose does not affect the flow that much. I've done plenty of tests and the main affect on flow is the height difference between shower head and pump. I run nearly 3m of hose and it doesn't affect the flow, the main thing you need to do is get the pump and unit about 1m off the ground, the pump struggles a bit to pull water up, if you have the pump in a bucket of water sitting on a table with the unit the flow will be much better than if the bucket is on the ground.

The problem I have found with the softer more pliable hoses , is that after a while with the hot water flowing through , they almost get too hot and to soft.

My supercheap shower was awful for that , I went and bought a Glind shower hose. Much better.
