I set up my first Glind hot water shower unit in a Toyota Land Cruiser way back in 1987; with one installed under the bonnet of every vehicle I’ve owned since that date! We camp away from home a lot and a piping hot shower at the end of a day is a welcome addition to any day!
The Glind hot shower concept is simple. Fit the Glind heat exchanger and associated Flojet pump within a vehicle’s engine bay and all it takes to supply hot water is to have the engine at normal operating temperature, heater controls ON, plus a source of water on hand. The pump extracts water from a bucket, or similar, and passes it through the heat exchanger before exiting the shower rose. And as the heat exchanger is warmed by engine coolant from the car’s heater system, the more engine revs the hotter the water. What could be easier?
The Glind unit can be installed in a wide range of vehicles, from sedans to utes to 4WD, with appropriate kits available. Tim from Glind Water Heaters and Pumps can offer advice on which vehicles may or may not have the room under the bonnet.
For the purpose of this article, we DIY fitted a Glind unit under the bonnet of a Nissan Patrol. The boxed kit comprised of the Glind heat exchanger that is marked to show water flow direction, pump, hoses, clamps, wiring, switches and fuse holder, some other equipment, plus instructions.
Connect the engine coolant through the bottom fittings of the exchanger with the water that’s to be heated entering and exiting the top fittings, one of which is threaded to accept the unit’s shower hose that can be screwed on or off as required.
In this case, the shower hose was connected permanently, although shortened with a click-on hose connection which is a set up for ready use at the camp site.
The mounting template to suit the Nissan Patrol was attached to the left fire wall area via some handy threaded holes, which is a feature of these vehicles. Once the template was in place, spacers were used to set the heat exchanger just a little way out from the template to skirt around existing equipment. No modifications were made or holes drilled, just a little cunning skirting around what was in place.
With the heat exchanger fitted, the next move was to cut one of the lines carrying coolant to the vehicle’s heater – a loop in one of these lines was conveniently close by – in order to re-route the vehicle’s coolant through the Glind heat exchanger and back to the Nissan’s fire wall via extended hoses.
Sufficient heavy duty hoses plus necessary clamps were supplied with the Glind unit for this procedure, and the instructions were concise and quite clear. A metal sleeve was used to connect the coolant line and the hoses going to the Glind unit and with hose clamps on each join there was no possibility of the coolant fluid escaping the system.
With the extended heater line fitted to the Glind heat exchange unit at the end nearest the engine, another section of hose was also fitted to the far end of the unit to carry coolant back to the vehicle’s heater system.
After all clamps were thoroughly tightened the next objective was to install the Flojet pump. Again a fitting under the bonnet of the vehicle was employed, in this case an upright plate attached to the mud guard. The Flojet pump was mounted to existing holes on the plate in a very satisfactory manner, with the supplied on/off switch and wiring (with fuse) going across to the vehicle’s battery to power the pump.
All that remained was to connect hoses bearing water in and out of the Glind heat exchanger via the Flojet pump with its dedicated fittings. The sufficient hose (including a filter at the end of it) was connected to the inlet section of the pump to extend only to the front of the vehicle so the bonnet could be closed with ease. Fortunately, the end of the filter was tapered to allow additional hose to be pushed on to it when it was time to access a water source.
With all fittings tightened a trial run saw hot water exiting the shower rose in fine form.Reads: 6148
