Shower Heat exchanger.

Ì suggest you check out what the heat exchangers are made from. Metal/copper/plastic etc. I think the pumps and plumbing would all be reasonably common. I'm not an authority on mobile showers, I don't have one but have seen some pretty shonky ones at 4WD shows etc.

I have a Glind. Works fine. The bigger pump allows for drawing water good distances and up a decent slope. The Glind is isolated from the vehicles cooling system via a tap. IE unless the tap is turned on engine coolant does not flow through the Glind heat exchanger.

See the Glind web site if you have not already.

If I may be so bold as to jump on this "bandwagon" to and ask my own question??
Is there a way to regulate the heat with these heat exchange showers? I don't have one but am interested but I haven't looked into how they actually work.. To my naive way of thinking I assue that if the engine is running hot then the water may in fact be too hot to shower under?? or am I really showing how little I actually know by saying that.. Any advice?

Haza,

Have you thought of the coleman gas hot water system, seems much better option for temp regulation in shower mode and other uses when camping, washing up ect. I personally have a glind but that's cause it is 8 years old an no other options were readily available back then, but it still works fine so why replace it. I have not put salt water through mine, but I would think this would not be the best idea if you plan to keep it for any lenght of time (just my unqualified opinion). The manual throttle on my GU works a treat for adjusting flow of hot water through heat exchanger to regulate water temp, but on a petrol pajero I had years ago I did have great trouble with water sometimes being too hot.

Cheers Trevor.

i have a glind shower unit and am very happy with it. If water is scarce we heat a enough water as soon as we pull up a bit hotter than we would like (about 5mins to heat 20 litres) while the car is still hot. This way u can turn the shower rose on and off to minimise water use and still mantain a constant temp. Where as if u are showering with the car running if u turn the shower rose off the next lot of water to come through out of the heat exchanger will be nearly boiling!!! To answer the other question there is a flow control on the shower rose so if the water coming through is to cold u slow the flow, if it is to hot u speed the flow. The chap at glind is quite helpful and will tell u how to set it up etc.

the problem is not with the heat exchange running salt water, but the pump is only designed for fresh water use. Why you would think of showering in salt has got me beat but each to their own, you will not run out of hot water with any of the commercial h/w systems. We run tags to the Cape and Gulf for up to 12 to 14 people and have not had a problem in 5 years of using a commercial system . Some just take a little more working out.
Happy Camping
