End of Year Summary 2011

Update for the end of 2011. Summary

1. After replacing the flow meter, balance valve twice it has stayed fixed for a while, so I am calling it done.
I ended up purchasing a valve from AliExpress and having it send direct from China. It is labeled as "Mechanical Flow Meter Balance Valve for Solar Pump Station, Brass, G3/4", Flow Rate 2-8L/min"
from Supplier 'Isabel SUN-LOVE'. The item arrived in a couple of weeks and fit fine, looked very much like the removed ones that Marshall Pan was sending me. Nothing against Marshall Pan, he is honest, a good businessman, his supplier just had a bunch of bad valves.

2. As the weather has cooled down, we have used the solar office air space heater. On sunny days starting about 9 am the loop liquid is warm enough to help, so we turn on the blower. That part of the office stays "toasty."
3. New Years weekend we had 3 days off and mostly sunny. Hot Water Release: Here is the release of water from the hot water tank.  The release was caused by over pressure from the solar heat transfer and no water being used for 3 days.Hot Water Release: Here is the release of water from the hot water tank.

Upon inspection the outside burglar alarm went off. This was about 2 in the afternoon. I went outside to see what set off the alarm and found the hot water heater pressure release had released a large amount of water and the steam set off the motion detector. In a few seconds more the spring loaded relief reset and the hot water stopped flowing. I ran some hot water out the faucet to bring the temperature down and will turn on the solar office air heater if we have another long sunny weekend with no water flowing.
