Coleman Hot Water on Demand Vs Companion Aquacube Logic Vs Companion Aquacube Digital

There are currently three primary choices of portable hot water systems available on the market today.  They are the:
All of these hot water systems work in the same way to produce the hot water.  They all use a small pump to pull the water through copper piping where a gas burner is heating up the water.  They are all very good, and for this reason are available from Tentworld camping stores.

This gas burner is adjustable, to allow for you to adjust the temperature to what you require.

However, there are some slight differences in them that will appeal to different people.  The advantages of each unit are:

Coleman Hot Water on Demand

The Coleman Hot Water on Demand, is able to put more heat water to a higher temperature.  This is particularly handy for those who like to wash dishes in very hot water.  The Coleman HWOD is able to get the water up to around 70 degrees.  Generally people prefer to shower in water temperatures ranging from 30 degrees to 42.

The Coleman Hot Water system runs from a rechargeable battery, and can be recharged from 12v or 240v. 

The Coleman Hot Water system is built into a plastic case, and uses error lights to communicate and errors it may be having such as over temperature etc.
Companion Aquacube Logic

The Aquacube Logic has a rechargeable battery built into it.  However, if this rechargeable battery is flat it is able to be run directly from 240v or 12v until you have a chance to recharge it.

The Aquacube Logic, is able to produce a maximum temperature of up to 47 degrees, any higher and a safety switch will turn the unit off.  This temperature range is perfect for showering, and general use.  It also appeals to many with younger families, knowing that their childen cannot burn themselves.

There are two water oulets on the Companion Aquacube Logic.  One is set up to simulate a hot water tap, for filling buckets the other is an outlet for  also offers two water outlets, one which simulates a hot water tap and another for connecting the shower hose to. 

The Aquacube Logic, also comes as standard with the shower hose as well as the carry bag.  These are extras for the Coleman though can be often purchased together in a package deal.

There are two temperature displays on the Aquacube Logic.  One for the hot water temperature read out, the other to tell you how how the water is thats entering the system to be heated. 

Physically the Companion Aquacube Logic is smaller, and lighter (9.3kgs Vs 10.5kgs)

The Aquacube Logic uses error codes on the digital screen to communicate any errors it may be having, such as over temperature etc.

Companion Aquacube Digital

The Companion Aquacube Digital Hot Water Shower 

The Aquacube Digital, is similar to the Aquacube Logic except that it does not have a rechargeable battery and can only operate from 12v.  This is seen as being advantageous by some people, who prefer not to have to look after rechargeable batteries. 

Similar to the Aquacube Logic, the Aquacube Digital features a digital temperature display for the hot water.  There is however, no temperature read out for the incoming cold water. 

The Aquacube Digital is also lighter than the Coleman or Logic at 6kgs. 

Hopefully,  this information will help you in making your comparison & review of the Coleman Hot Water on Demand Vs Companion Aquacube Logic Vs Companion Aquacube Digital

  1. We found that the hot water is actually cold still on the tap outlet even though the temp is set to max but the shower gives hot water after a few seconds. The hot tap outlet did not warm up and only took the chill of the cold water

  2. That's interesting, can I confirm what Hot Water System do you have?

    When you're running low on gas this can happen, as the burners can not reach full temperature? Check your cylinder to make sure it's full, and the tap is opened up fully?

    What temperature was the incoming water?

    What happens when you slow the water volume down using the hot water shower head?

  3. I have a coleman and just bought the aqua cube logic. The logic is miles above the coleman for showering. The coleman produces a higher heat for coffee.

  4. Yeah I tend to agree Brian, if you're after water nearly hot enough for coffee then go the Coleman Hot Water on Demand system.

    If you're wanting water only hot enough to shower in and otherwise use then the Companion Aquacube Logic is a great choice of camping hot water system.

  5. Thanks for the blog, this was very helpful when deciding which hot water system to get. Think the Logic is the way to go.

  6. is there any possibillity to get the heatingregister from one of the aqua cubes? i want to build up a system similar to this, but not so sophisticated but for rougher environment.
    I can only use gasoline burners cause I don't carry gas with me, so I wanna try to heat it up with my white-gas stoves.
    propane or butane/propane mixtures don't work any more at low tempertures in a harsher environment like northnorway or iceland
    the zodi extrem could be a solution but not desireable for me due it's big size

  7. I have the coleman system , 14 mths old already had replaced under warranty and now the second one has stuffed up, the ignition system again !!!
    Very unreliable , very disappointing

  8. Have a Coleman and when working is good but like there eventemp stove is totally unreliable. mine has been used 5 times, internal charger not working, had to replace front temp nob, pump on hose is now stuffed and there service is a joke. Will buy a Cube and see how much better they are. Oh and the eventemp stove replaced regulator 4 times is 12 months bad gas leaks! Tentworld guys Ipswich had a new better one made up for me, thanks for that guys.

  9. Hey Steve, thanks for your feedback. We've definitely not experienced the level of difficulty you've been having with your Coleman products. You've been quite unfortunate certainly if all Coleman products were like what you've described we would not sell them. I'm glad that the team at Ipswich were able to help you out and that you enjoy your new Companion Aquacube Logic! Cheers, Jon

  10. Has anyone purchased the hey presto instant hot water electric tap? We are thinking of buying one for our caravan and would like to hear what other have to say.

  11. Hi Mary, I have not heard of any reviews on the Hey Presto instant hot water electric tap. I had a bit of a look at their website before and I do not think that it'd be particularly useful when camping or caravanning because of its very high energy consumption. It would only be suitable if you only ever went camping in places that had 240v mains power available. Hope this helps with what you're wanting to know. Cheers, Jon

  12. I have now purchased 3 Colemans highly advise stay away from them all 3 had same problem would cut of saying battery flat even though just come off charge tried new battery still happened now none of them work disappointed

    1. Had same problem here with the battery on my Coleman.

    2. Had same problem here with the battery on my Coleman.

  13. We also had PLENTY of issues with our original coleman hotwater on demand system. Battery issues, underheating issues, etc. We treated it like gold b/c it was so expensive but still had these issues. It was kept inside when not in use, it was stored, drained, etc. properly. The worst issue was that Coleman was less than helpful.

  14. Sorry to hear of your bad experiences Buddy & TheFishbulb80. It sounds as though you've both had frustrating experiences. We find that we get good assistance from Coleman when we do have warranty issues with our customers. If there were big ongoing problems with these units, we would not continue to sell them as the cost of processing warranty claims makes the sale not worthwhile. We'd much rather see a customer buy the right thing the first time.

    We have found the Coleman and Companion hot water systems to be both good systems worthy of your purchase.

  15. First time we had used the Companion Aqua Cube Logic II only for 1 month after the pump opened itself up and the seal was hanging loose with the water going in to the electrical parts of the pump. We got a replacement what took 2 months to arrive to us. The replacement pump worked fine for 2 months and again the seal came today out and the pump filled itself with water and stopped running. It’s very annoying when you not touching or moving the pump in any way and it falls apart / opens up by itself and we not want again to wait again 2 months for a replacement pump as we need this cube. I don’t understand why they cannot put something on it that holds the pump house together so the bottom part where it sucks the water in can’t come loose??

    1. Hi Flying Dutchman, I'm not totally sure from what you've written but it sounds as though you're possibly using the Aquacube Logic in a permanent installation scenario where the pump is always submerged.

      This is not what the system has been designed for. The pump is designed for portability and camping where the pump is dried out on a nearly daily basis. This probably explains why you're finding the glue failing that holds the seal in place.

      If you do want to use the system in a permanent installation, perhaps investing in a pump designed for this purpose and the purchase of this accessory would be the way to go?

      This Companion Aquacube hose adaptor allows you to eliminate the pump from the unit, and use an external pump to provide water flow. This might be the best solution for how you appear to be using the system.

      Please let me know if I can help further!
