Am considering using a Coleman or Primus shower heater as basis for simple general water heating in our TVan. Concept is to connect via tank and larger pump, then plumb to sink etc. Also connected to larger gas bottle.

Heater would of course be external

Would appreciate comments from anyone who has done this - there are a few comments in the archives - but nothing current.

I had a Primus and now have a Coleman. Primus is overall poor design and implementation. Coleman works as described and gives instant hot water quickly without stuffing around. I have our Coleman connected to a larger water tank with pressure pump and also a quick disconnect gas fitting to a 9kg bottle that is AGA approved that looks like a Ryco air hose fitting.
To put it succinctly the Primus takes a lot of stuffing around, the Coleman you twiddle the knob and you have hot water. Is that simple enough for you?

The reason that I didn't buy the Coleman in the first place was that the accessory gas hose was not available in Australia.
But, I too must admit that I like the general portabilty of the self contained cannisters. We found the Primus to be fiddly to operate & annoying in the extreme with its over temperature gas shut off.

Shaker the accessory gas hose is available in Australia and they arrived 6 weeks after the hot water systems. Coleman has a 1800 number you can phone and that is what I did when I wanted to know about the gas hoses. You can refill the Coleman canisters with an adapter you buy from the US. I use a 9 kg gas bottle with our and our friend refills the disposable gas cannisters 10 times as they recommend in the instructions that comes with the refill adapter.

I can assure that they weren't available for quite some time after the HWS was released in Australia, which is why I made the initial mistake of buying a Primus.
My comment was that after thinking that it was necessary, I find that I prefer the disposable cannisters.
I mus admit that I have never heard of the refill adaptor & would appreciate more information & how much is each refill?

I bought a Coleman before xmas for our High Country trip.
First thing is that its plastic and quite bulky - sorry to state the obvious. LOL

I was using it as a shower and the pump was lifting approx 1m with excellent flow.

The self ignition worked well and gas use wasnt too bad although I havent finished the disposable gas bottle yet to be sure. It has done about a dozen showers plus a LOT of playing around with it. I also have the hose that allows it to run off of normal gas bottles but I quite like the self contained nature of using the Coleman bottles. Disposable bottles are wasteful though.

Its a good product Collyn, if its bulk can be accommodated.

regards

Andrew

Hi Collyn,

The Primus Hot Shower unit is a much maligned product, I have spent considerable time investigating its shortcomings and their potential solution(s), I have one and think it's great for our requirements.
Contact me direct if you would like some details.

Hi all,
Last month in QLD (we are from SA) they had both gas leads [POR? and the other method of connection (3/4") thread ones?] to connect the coleman hot water system directly to a 9kg gas cylinder. We also got the garden hose type pressure attachment to connect the system to a normal hose. This is the beginnings of the system we are putting in our caravan with two hot water outlets - one over the sink and with a T-piece to the outside to connect into to a shower tent. We will eventually get a gas fitter to connect to the caravan gas supply - probably near the stove hotplate gas line.

The stove hotplate in a caravan uses low pressure gas and is piped after the regulator on the gas bottle. Your Coleman hot water system requires high pressure gas. You can run from a separate gas bottle, or you can purchase a lump of brass you can put on your gas cylinder so you can have your current regulator as well as the high pressure connection for the Coleman.

Front to back 420mm including knob
height 410mm
width 220mm
weight with pump and no gas cylinder 9.7Kg

Yes it's bulky but works very well, no problems with overtemp cutout as it doesn't happen till 70deg C then it automatically reignites when the temp drops. Have used mine with a 12V pressure pump and the mains water adapter, works very well, no problems with the pump priming and if you tweek the regulator inside the adapter you can get more flow.
Even though your not meant to refill the cylinders I have done several with no problems, the Yanks have been refilling them for years. Just check the valve is not leaking after refill and that's it. Even non refilled ones can leak if screwed on and off many times and it has a dodgy valve. Got my adapter off EBay. Worse case is if the cylnder is overfilled the valve will vent gas, this has never hapened to me, it's no more dangerous than filling your car up with petrol. Just observe some basic safety and enjoy your 70 cent gas refill instead of $6.95.

i must put in my 2 cents worth, we bought a primus water heater and haven't regretted it for one minute. yes for the first couple of lights it took some getting use to then we played around ignored the instructions and now it's so easy to light first time every time and we have never had a problem with the water cut off. we too were tossing up between the coleman and the primus and we are glad we got the primus. good luck.
