I am updating my original review (below) because Joolca staff got back to me and fixed the issue. They gave me a refund for the difference right away. We haven't used the shower yet but so far the experience is good. I would still warn that for gravity fed you need 15m drop or get the pump.

(Original post)
We purchased the essential kit, only to realise you need 15m drop to work without the pump. I called customer support in NZ and AU all day, but both went straight to voicemail. I purchased the pump separately but if it was made clear I would have saved money by ordering the pump together at once. Very disappointed.

Very disappointed with this unit. Purchased it and pump direct from Joolca 18/01/17. Used it twice on a camping trip 26/01/17. Shower rose broke so replaced it with after market metal one. Next time I tried to use the unit it would not ignite. Sent back to Joolca on 16/02/18 for repairs. It worked maybe twice again then sat in the camper as dead weight. Tried again recently and again would not ignite. (Joolca suggests maybe a pressure switch). As unit is now out of warranty Joolca no longer back the product. Having used it only about 10 times in 3 years it still looks brand new. I will be cutting my losses, trash the unit and buy a different brand.

Great unit and very good communication from staff I've brought two hot taps, double ensuite, ensuite plumbing and about to by another ensuite plumbing set have one setup for caravan other set up permanently out side can't fault any of the products

Ordered unit one day it arrived the next day and it's everything it was claimed to be, so I would highly recommend this unit to anyone needing a semi portable/ portable water heater

Facts- easily goes out with little wind
Also randomly just fails about 10seconds after ignition. Joolca Have instructions on website to block vents as it obviously a known problem... not happy with this product also no phone support!

Product didnt heat took it back to get replacement that one didnt work either not at all happy with the product or the time it took me to go to the local store to swap them over

Using one for bush camp, I now enjoy camping! This is 2nd unit purchased for our shed shower. Great service, easy to use, very happy so far with my Joolca.

The Hottap is great for our situation! We live off the grid and only need hot water for a few months each year. It is set up in our open-air bathroom and is working a treat. So good to have instant hot water without having to light the old donkey!

Great little system when you r free camping no going to bed dirty
I would recommend the joolca hottap to anyone that does enjoy the great outdoors and you will be surprised as to how little room it needs for storing

I have used the Joolca HOTTAP regularly for the last 3 mths and cannot fault it. After a few adjustments during the setup, I have found it does everything that is required. I confidently recommend this Joolca Hottap as an essential piece of equipment

What a great piece of kit this product is! Quality fittings with a rugged construction. Once water pressure and gas flow was sorted we were enjoying warm showers. The only thing that could be improved is having to lower the flow rate to get a higher temperature, but honestly, this is truly a minor inconvenience, and only an issue in really cold weather.

The Joolca HotTap is a remarkable unit, I purchased it in 2015 and is still going strong in 2022. I cannot fault it at all. Water temp stays at the settings I set and the unit will cut off if the pressure gets too low. Fail safe work well.

I am very impressed with the shower. I have caravanned and camped since the early 60's with many combinations of rigs and I must admit that this is possibly the greatest. We have it set up to operate in an ensuite Annexe on a small van and it has operated and performed wonderfully. It's the wife's favourite piece of equipment.The product is simple to install and operate and appears to be well constructed. Couldn't recommend it better.

Very simple to set up, connect and use. Fills a much needed space in the camping market. Can't beat a hot shower and a cold beer at the end of the day when out bush in FNQ.

The product arrived to great anticipation & when unpacked it was clear that its extremely well made, it was also very easy to install & an absolute joy to use outside whilst we are remodelling our bathroom! Im keeping it where it is so I can enjoy an outdoor hot shower in my backyard! Love it!

I live offgrid, so I bought this product so I can have a hot shower, without having to pay costly fees for a plumber to hook up a gas hot water system. I love it. It is perfect for my situation. The customer service these guys provide is absolutely brilliant. Well done on an amazing product

Works great, exactly as advertised! Easy to install and easy to use. Shipping was fast and communication has been a breeze! Excellent value for money! Highly recommended! We use it everyday!
