Helton In Vehicle Shower Kit (BLUE) Heat Exchanger
An in-vehicle hot water system is your key to unlimited hot water!
All you need is this kit, a radiator and a water source (stream, lake, creek, bucket) and you will have hot water showers all year round, rain or shine.
The heat exchanger is inserted into the vehicle's heater line, a 12V pump then draws water from your water source through a separate line in the heat exchanger (meaning the shower water does not mix with radiator water or coolant).
With the vehicle running at idle, or just above, and at operating temperature there is a transfer of waste heat from the engine's cooling system to the shower water.
The result is astonishing, unlimited shower water instantly!
The heat exchanger itself is manufactured entirely of high-grade copper for maximum thermal efficiency and durability.
With a one piece heater line there no internal joints within the unit. Tube ends form the hose barbs so there is no fittings to screw in and no joints to leak.
To ensure you receive a quality product; all joints are brazed and pressure tested and the copper components are punched, pressed and rolled by the manufacturer to ensure uniformity.
The units are manufactured with all 4 hose connections at one end.
Blue Shower Units are designed to achieve a shower temperate range of 38 to 42° C for shower purposes at a fresh water flow of 3 litres a minute for the camper needing to be conscious of water conservation in a situation where water is transported. From experience, a fresh water flow rate of about 3 litres a minute is adequate for a bush shower, but less than one would expect from a shower at home.
This is the complete installation kit, it has everything you will need including:
The Vehicle Camping Shower (This Kit) has about 2.8 meters of heating coil and is designed to deliver shower temperature water directly from the unit. The Hot Water System has about 4.2 meters of coil and will deliver much hotter water.
Mount your heat exchanger using the bracket provided.
Your heat exchanger has 4 connections. The coloured collars on the connections identify the relevant hot/cold connections.
2 large ones are for connection to your vehicle coolant system.
2 small ones are for for your fresh/shower water.
Although your Heat Exchanger will work when mounted in any position it is most efficient when mounted upright or on its side with the hot fresh water out and the engine coolant in hoses (both red collars) uppermost.
Heat Exchangers are designed to be fitted in series or parallel with your vehicle heater system.
Mount the bumper bracket on your bumper or other easily accessible location.
Connect the 2 barbs on the bracket to the inlet and outlet on your heat exchanger.
If mounting your Heat Exchanger high up in the engine bay, it may be necessary to rotate the exchanger so the "engine out" connection is vertical. Start and run the engine for a short time. This will eliminate any air lock that may have formed.
Note: If you have a shower enclosure or wish to wash away from your vehicle, you can gravity feed fresh water from a drum or bucket on the bonnet through the heat exchanger into another container.
First burst of water will be very hot as this was trapped in the heat exchanger, water temp will drop to around 50-60°C and then be delivered continuously for showers etc.
Do not install the Heat Exchanger or hot water outlets inside the passenger compartment! All components should be under bonnet/ under car or on bumper bar.
