    After spending money on a Gas water heater that isn't suitable for window cleaning, I though that I would share the information and maybe others who have paid for heaters that also aren't suitable could do likewise on this thread?

    Yes, I have used another shower successfully, but this was to be a replacement after a few cracks developed in an internal pipe in the broken shower. This thread isn't meant to ask questions, but as help to others NOT to buy these heaters as they aren't suitable.

    Hopefully others will continue the list if they have had the same misfortune as myself i.e. buying a heater that won't do the job :(

    So, the following shower / water heater isn't suitable as the ignition won't kick in when we need it to. The problem appears to be that the sensor needs either more flow or less back pressure to work. I have used this with a 6mm extension hose and a 8mm extension hose, and it won't work. It works with the shower head that comes with it, just not our narrower hoses.

    main reason is that its a 8l one.

    it can produce 8lts a minute, the pumps that most people use can only supply 5.2lts a minute, on full power, so when we use controllers the flow rate gose to half at most, only pumping about 2.7lts per minute.

    always say to people that ask only a maximum of a 5lt one

    I had a 12L water heater working just fine on my van set up - just too hot to use unless the air temperature is sub zero during the day.

    This 8L one also runs fine with my pump, if I don't put a narrow hose on the outlet i.e. 8mm extension hose. But a low volume of water with a 1/2 inch hose or the included shower head is fine.

    Even running 6l per min in and out to two extension reels and poles doesn't work.

    So, I'm not convinced that the problem is that it is 8L

    never had a problem with our eccotemp L5 heater,

    maybe its only the cheap ones that are no good???

    plus they are not designed to run up 2 hoses as the pressures are always changing
