- This is the Gasmate WaterTech Hot Water System.
I'm gonna tell you about all the features and how to use it,
let's get started.
(upbeat music)
I've got the Gasmate WaterTech hot water unit set up
or hot water system set up next to me here.
I've got it standing on, the optional stand
the gasmate make for you
so you can set this up in your campsite
next to your vehicle, your shower tent, whenever you want,
you can have hot water, no matter where you set up camp.
I'm gonna show you how to use it
and all the features in a sec,
we'll run through a few of the basics first.
This is a unit here measures about 40 centimetres
from the top to sort of the bottom
of where these plugs stick out of the bottom here
about 29 centimetres in width
and about 14 centimetres in depth
that doesn't include the knobs on the front here.
Now the output of the unit is about three litres
or it's litres per minute from the unit here
but the pump itself
is actually an isolated per minute unit pump
They limited the flow of the water through the unit
to make sure that the hot water actually reaches
temperature.
If the water's flowing too fast,
the heat exchanger inside can't heat the water up
quick enough.
So to consume about 568 grammes of gas per hour
from your gas bottle
which is about 16 hours from a nine kilos bottle
or almost 200 showers.
I've got it today connected to just a 1.25 kilo gas bottle,
which is gonna be more than enough for a family
afford a shower for a weekend.
Now it comes with various hoses
you get a five metre power hose here that can go...
I've got this plugged into the back of my vehicle
at the moment, so five metres to the vehicle,
you get a one and a half metre hose to the pump.
Now this pump, gasmate recommend you just use
clean water with it.
They haven't set this up to be able to pump from streams
or rivers or that sort of thing.
The shower hose is a two metre long,
shower rose has just got a single setting
it doesn't have adjustable settings on here,
and it's got the on off switch on here,
which is what turns the unit on and off
once you've got all the gas and power connected to it.
Now just a couple of other things on the pump
before I go any further,
this is a good quality water tech pump,
it's not one of those cheaper ones that tend to burn out.
It's a brushless pump.
If something does happen to it, you can replace this pump,
they're available as a spare part.
Now, as I mentioned,
Gasmate haven't made this unit to operate
by sucking water from a creek or a dam
because of the sediment, I liked it,
they say prefer to use a fresh water
or clean water with this.
And you can't attach it directly to a mains water outlet
and main reason being that it's not designed
to operate water at that pressure. To be able to do that
you'd have to put a pressure reduced down to like .6 MPa
but there's nothing readily available
necessarily to do that.
And some other brands might make something,
but it doesn't come with the unit
you'd have to get an adapter to make that happen.
Now moving on a little bit further
to the actual unit up here.
Now, the whole thing weighs about five kilos.
This is a powder coated steel outer on here
am just gonna put my wet hands here a little bit.
And there's three dials on the front
and a little outlet temperature gauge here.
So the three dials are the gas, this is your gas control.
Now, it takes a little while
to get used to sort of how to use this
and how to get the most out of it.
But you've got a minimum and a maximum for winter
and also a maximum for summer.
So summer gas control can go all the way round
and winter will only go to here.
If you go any higher than that on winter
it's actually gonna cut out
because the temperature rating will go over 50 degrees,
AGA gas laws depicted,
it has cut out at a certain temperature
which is about 50 degrees plus or minus a percentage.
So if you wind that up any further,
it would go too hot and it wouldn't be legal.
So it actually cuts out if it goes much higher than that.
Now, when I talk winter and summer
that's to do with this dial here.
There's a summer mode and a winter mode.
When this is on winter,
the heat exchange inside is operating at a hundred percent.
So you're getting the most efficiency out of the unit
in terms of water temperature, but it's using more gas.
Now, the unit will raise the temperature of ambient water
by about 25 degrees
up to, as I mentioned a maximum of about 52 degrees.
Now, if you're in summer and the water's already warm,
you don't need to be burning through that much gas.
So you can just turn it around to the summer setting here.
And that reduces the performance
of the heat exchanger inside to about 70%.
So you're not using as much gas,
you're gonna get a longer use out of it.
It's just not going to raise the temperature quite as far.
However,
if you're in winter and you're using below 10 degree water,
you're probably gonna want this on the winter setting
so that you can raise the water up to a temperature
that makes for a comfortable shower
bearing in mind that the normal shower
is probably around about 34 to 38 degrees.
And lastly,
this dial on the right hand side here is the water setting.
So high to low setting there,
to get the unit started, which we'll do now,
we need to have the water on high and the gas on low
There's a little quick start guide sticker here.
Follow this religiously.
If you don't follow this
then the unit won't align properly,
and you'd just be tearing your hair out.
And if the unit does happen to cut out, turn everything off,
go back to this guide here and then light it up again.
So to get started, make sure our pump is in the water here,
give it a shake to remove any sort of water traps
or any traps that might be in there
because that can affect the pressure going into the unit.
Secondly,
make sure our gas is on at our gas tank behind us here.
We're gonna grab the shower is in my hand.
We need to make sure that the middle setting here
is on the summer setting.
This is following the quick start guide here.
Gas control is around some minimum on this side here.
And water flow is on high, which is around this side here.
They are the settings that needs to be in
before we start it.
We then grab the shower unit rose here,
we flick it to the on position.
So push that side in there for on,
I'm gonna hold this over the bucket here,
'cause I'm gonna recycle this water.
From there, we come underneath the unit here
and we flick the unit on.
The pump should start up and the unit should start to flow.
So it takes a few seconds, I can hear the unit it's now...
I can hear the burn and lighting inside the unit here.
Now we've got water flowing
and it's already up to 30 degrees.
Now I have got this re-circulating through here,
so that can make it more efficient
because it's sucking in already slightly warm water
through the unit and it's reheating it,
so it's making it slightly more efficient.
But that's quite a spread out
sort of shower rain head on there.
Now to turn this off again,
if we're in the shower we want to turn it off,
all we need to do is flip this switch back the other way.
We will see the unit shuts off up here.
So that's now shut off so there's no water flowing.
the water stopped, the gas is stopped.
Nothing's happening so I can have a break or do what I want.
If someone else comes in to use the shower,
then I'd have to shut it off here.
It's happening straight away.
If you leaving the unit for a while,
flick it off completely turn the gas off.
But if it is just for a few minutes
you can turn it off here,
if we then flick this switch again,
we'll see that this thing automatically lights up.
Give it a few seconds, we can hear that psi click,
you can hear it a lot inside
and you can see the temperatures lit up again.
Now in terms of adjusting the temperature
with the dials up here,
this is a minimum gas at the moment,
with a high water flow.
Now the faster the water flow, the cooler the water is
because it's moving through
the unit is not heating up as much.
So first thing we can do to heat it up
is actually reduce the water flow.
So if I dial this down now,
we just have a look at what happens with the shower
as I continue lower that down to low,
we can see the water pressure drops right off,
but the temperature is gonna rise
probably only by a few degrees.
It's gonna take a little while for it to flow through
'cause it's right down to a really low pressure.
If I was to take the shower rose all full together,
it'll be up to about four litres per minute
coming out of the tap,
but with a shower rose on, it's about three litres.
So we can see that temperature has raised.
The other thing we can do
and I'm gonna dial that round to high again now
'cause most people want a high pressure shower
so we've dialled that around there.
Now we're on the summer mode, which means with the gas,
we can actually want to round around to summer max,
which is right around that side there.
That's gonna increase the heat of the burner inside
and we should see this temperature rise
just a little bit as well.
So that's using more gas and water
to get the same temperature.
So you kinda need to play around
with these dials a little bit.
If we're still not happy with a temperature that got in
now, that's a pretty good temperature for an average shower.
That's a full flow three litres per minute flow there.
And that feels nice and warm up to 43 degrees
as gradually heating up more and more as we go.
Now if we're still not happy with that
or the water in the bucket here is now warmed up
'cause it circled through the unit a fair bit,
but if we've got really cold water, less than 10 degrees,
we probably need to put this on winter mode.
Now to switch that to winter mode,
first thing we wanna do is flip this around to a minimum.
If we don't,
the unit's gonna heat up really quickly and cut out.
So we flip this around to minimum
we'll leave the water on high still
and we flick this around to winter
and we'll hear the unit inside
actually fire up in full so I can hear another burner
or something going on inside there.
I can see the temperature slowly rising.
Now I can run this around now it's up to 45, 46 degrees,
and that's with the gas on minimum here in the winter mode.
If I turn this around, it should get to about 50 degrees
when it reaches winter Max actually that's cut out.
That's a safety mechanism of the unit
because the water in some of my bucket here
is already pretty warm.
I don't need this on the winter mode to have a hot shower
so we can tell that it's cut out in two ways.
Firstly, the temperature is dropping back down
to just the ambient temperature of the water.
And second,
there is a review window here where the pilot light,
we can see where the pilot light is burning
by looking there at the moment,
there's no blue flame in there,
so the gas flame has gone out.
So to relight this now
we need to turn it off at the shower rose
to stop the water flow.
We go back to our summer setting.
Now, if this keeps cutting out,
you got to question whether you need it
on the winter setting.
Once again,
if your ambient water temperature supply is below 10 degrees
use winter.
If it's above that use summer.
I'm gonna dial this back to minimum,
this living it on high, and then I can start the unit again.
And with that water circulating
the temperature inside of this water
is probably gonna be around about 40 degrees or low forties
anyway when that slowly creeps up again.
Bearing in mind when you're trying to adjust the temperature
and water flow,
if you're shower here,
there's no hard first rule around that.
Gasmate's major general recommendation
is to have it on the max setting
for whichever season major in and then use the water flow
to adjust the temperature
because as you lower the water flow,
the temperature is gonna increase
'cause the water is passing through the heat exchanger
at a slower rate.
Now that doesn't always work
because sometimes you just want a bit more pressure
in your shower.
So you want that high water flow,
which means you might need to play around
with which season setting you have
and how much gas you've got coming out,
bearing in mind that you don't really want to play around
that maximum temperature to have it cut out
because there's nothing worse than having to get out
in real life shower all the time.
Couple of other things I mentioned
is permanent mounting of this unit is not a legal thing.
The Australian gases association
don't allow you to instal this
to be permanently mounted anywhere,
which is why they don't have any brackets or anything on it.
It's a portable unit to be mounted on a stand like this
or the side of a vehicle
or so non-combustible set of surface.
People also ask you if you can have two different outlets
on a unit like this, you certainly can.
There's nothing readily available,
but if you can adapt something
to have two outlets off of this that would work.
Using both at the same time,
obviously you're gonna have typically reduce
the flow rate and a may affect how this unit operate.
So probably only use one side at a time.
It's pretty much all the features
of the Gasmate WaterTech Hot Water System.
Our mechanism is a pretty simple, reliable
and is a nice sturdy feeling unit
so make sure you've got a nice hot shower
or hot water to wash up in, in your campsite
no matter where your adventures take you.
