This summer in Australia it's a bit of a scorcher! Boxing Day (day after Christmas Day) was 44.3+ degrees celcius and since then it's cooled down to 40+ and now a couple of weeks later just a mere 35+ d celcius. I can't get developing as the water out of the tap is too hot hot hot. I really need to get that temp control thing happening in the water pipes. Have you done this before? Please correct me if I'm wrong, but I thought you can only control temperature by warming it up, not cooling down. Is it easy enough to do yourself?
