I bought one of these showers yesterday, and I have the same issue. The water is WAY too hot to shower with at the lowest heat level. I tested it out and it hurt! Granted, I'm also in QLD and the water temp going in is warm, but I'm wondering where in Australia, in the summer, would the water temp (even in a container sitting in the shade) be under 20 in the day?
Searching for a good hour yesterday, I couldn't find anyone else on the internet who had this same issue - is it possible that this is a thermostat problem?
Anyway, I'd love to know how you removed the flow restrictor as I can't see how to do this?
Doesn't removing the flow restrictor mean you go through an awful lot of water for a shower?
I have thought of just recirculating into the container until a reasonable temp is reached and then shutting down the gas and just running the pump with no heat, but I feel this kinda defeats the purpose of the thing!
Thanks!
