Joolca Hot Water System

Yep, that's what these units come with.

EDIT: Actually, it came with the pump they sell, not with the unit itself.

When I have a camper I'll get one of these for sure

Sorry for the delayed response. I thought I’d receive email updates for new posts, but I must have missed the option?

Firstly, really good question.

I have seen the post with that image on the FB page. Personally, I think it boils down to user fault. This wouldn’t have happened if the user used soapy water to check for leaks. For me, this is common practice with my gas appliances such as my HOTTAP and my BBQ.

Portable water heaters need to pass rigorous testing in order to get compliance to be legally sold within Australia (or whichever country they are being sold in – for example, NZ needs a separate approval). So, first step would be is to ensure the unit you are looking at has relevant approval. I’m pretty sure the unit in the image has relevant approval.

In terms of the fire spurting under the unit, my experience tells me that one of two things has happened;

1. Cracked gas assembly
2. Loose connection/ fitting

A cracked gas assembly can come about from being dropped/ knocked hard on the gas valve or from over-tightening. From factory (our units and most likely others) are tested before they are shipped here to our warehouse. So, it is highly unlikely to have a cracked assembly from brand new.

I’m pretty certain that the fault in the image was due to a loose/ faulty gas connection (not to do with the unit).

In terms of safeguards, like I mentioned before, make sure the unit you want to get has relevant approvals. Aside from this, I highly recommend using soapy water to check for gas leaks. This is a cheap and easy way to start covering yourself from potential danger. Also, use a spanner to tighten the connection – no hand tightening.

In saying this, these types of units (eg.: HOTTAP) are actually pretty safe. No pilot light, just a piezo to spark up – similar to your BBQ. Over temperature sensors, flame sensors (cuts out if senses no flame: stops release of gas into atmosphere). They’re not made to spit out flames, they’re made to heat up water.

Thanks for that! I may look into it :)

I'm not a fan of the drawbar mount, it means you have to have the shower setup within a couple of metres of the trailer, and if you're a fan of long hot showers like me then you end up with a muddy mess around and under the camper.

But on a freezing cold morning camping there is not much better than jumping in the shower for half an hour, pumping water out of the creek so you don't have to fill buckets. Once it is set up it is effortless to use.

Half an hour?? How's the water bill mate? :)

Hi Bart

This makes sense. I did notice that the gas bottle didn't appear to be fix to the trolley, so damage could of easily occurred while they were moving it around.

Thank you for taking the time to reply and explaining the safety features.

Cheers Rodney

Is this just a non return valve, I like your idea of drawing water from the river.
Might need a cage etc to stop sticks and stuff, I take it this would work using
those smaller gas canisters. I have my light poles that would be perfect to
hang the hand piece off

Yep this is the screen filter I have as well.

They are not a small unit IMO only a little smaller than a house instantaneous HWS
More stuff to take away, but the luxury of having hot water at the click of your fingers
sounds inviting

Yea the whole idea of portable is crazy..
I guess it's portable due to electronic ignition..

It's about the same size as a slab of beer.

Stubbies or cans?? 😉

Cans......

Haha, guys, terrible of me. My apologies for coming in an out of your lives like a one night stand.

@NissanGQ4.2

Thank you for the bump and thanks for the tip, hopefully I did it right this time?

@Yendor

My pleasure :)

@threedogs

That is actually a small in-line filter and not a non-return valve. This filter would be good for relatively clean water from a bucket or jerry can. You could couple this with a Screen Filter (http://www.joolca.com.au/screen-filter) as linked already. The SF would sit inside the river/ creek and it would keep out all the larger stuff.

Also, you'd be using standard LPG BBQ type gas bottles with these units. From what I understand, if you wanted to use the small gas canisters the unit would probably not work as the small gas canisters don't have enough pressure.

Bump as last post went into moderation

Did anyone end up with one of these and if so what are your opinions of it?

I love my joolca Hottap. Had a Aquacube before hand and purposely sold it with the camper trailer so I could get a Joolca for the new one :)
