Redleader, Mounting pressure I have no real idea. I am using springs which are almost hard down but I don't know. A wild guess would be 8-12kg based on the spring hardness. I will measure this.
Right now I have a strange effect:
The water temperature is oscillating. Two pumps, a sick 110v eheim at 50hz and a Hydor Seltz S30. The temperature oscillation remains with either and both on. It is not an electrical/interference problem, the temperature stabilises when I restrict the flow and the period is too long I think. It is some kind of pump output power variation or a system time constant I think. Groth I am reminded of our pump/fan water PWM generator discussion.
I wonder if anyone (Bill?) has seen or can explain this.
Edit: I beg your collective pardons. I have discovered that it IS in fact an electrical issue. Measured the water (not distilled at this early stage), its got a 40VAC level relative to house ground. The eheim pump is not grounded. Grounding the radiator removes the effect totally but grounding the pump has no impact.
Effect of grounding the radiator:
You live and learn.
Edit 2: This is actually quite interesting. The signal I was seeing must have been induced into the water. It was there with either pump off, so both pumps must have been contributing. This means that this could be a generic problem, I wonder if this has any effect on anyones overclocks??? Use distilled water!
