you may both be right - we were told today that we had the wrong pump - they replaced it and I guess in a few days I'll know if they were right - would an extra 5 tubes make all the difference? I wonder...
Evacuated tubes operating in Brisbane during cloudy days in winter

MemberSerg77, I had my evacuated tube system initially installed at 18 degrees and it was fairly useless in winter. I then got a low-pitch roof frame put underneath the collector and jacked it up to 31 degrees. It works a LOT better in winter (and solved my overheating problems in summer). I would suggest you do the same.

Memberthanks Ben, I will keep that in mind if things don't improve, we had a new pump installed yesterday and it appears to have solved things so far, it has been two days since we had to turn booster on and water is still hot, so far so good, I guess we'll know tomorrow evening if it has really worked.

MemberJust a note about the operation of ETs in "Siberia" and sub-zero temperatures as mention in the original post on this thread. I have observed our Apricus Evacuated Tubes covered in ice early in the morning in Canberra and still producing heated water - admittedly only about 20 degrees C at that time of morning but still heating nevertheless. System is at around 50 degrees elevation and facing almost true North. As long as you have sun falling on the tubes they will be capturing energy.
