Hi all,
I popped into see a job today with a problematic solar system.
12 evacuated tubes
Twin coil cylinder in the loft, along with pump station and expansion vessel.
System not circulating but pump running, I checked the expansion vessel and saw it was badly corroded and leaking Goooo!!
Pressure gauge reading 2 bar but I think it is stuck, the sight glass for flow rate was mucky.
Obviously the leak has caused air in the system which is only 3 years old, the expansion vessel has already been replaced because it was leaking.
I presume the system was not cleaned out before final commissioning and the flux is now corroding the system ??
from my course @ Worcester 2 years ago I'm sure they said a there is a minimum head for Evacuated Tubes??
Can anyone confirm?? or dismiss my theory:2guns:
The customer is 85 years old and a little fed up after spending £7000 3 years ago.
The system was installed by So Solar of Southampton
