It's a yearly subscription, but more importantly why bother? It is pointless to attempt measuring fractions of a degree anymore when practically all the like products anymore perform pretty much the same. At a 5C water/air delta (which is what I like to run), the difference between worst to best radiator(17-24% max differences) is a measly 0.8C. If my house fluctuates in ambient temperature by 10C due to using a woodstove for heat, then a fraction of a degree really means nothing at all.
I got into this originally because I liked the craftsmanship required to fabricate a loop back in the days. I migrated to testing because I liked learning about the science behind it. Today everything is pretty much bolt together, people ***** about missing warning labels, and putting a loop together requires little to no fabrication or mechanical skill.
For $6/mo, I could treat myself to a monthly BBQ chicken sandwich, seasoned fries with ranch, and a medium diet pepsi (It makes up for the sandwich..lol).
I just bought Crysis 2 on steam for $12, Portal 2 for $5, and that $6 BBQ sandwich is looking REAL good right now..lol.
As always, anyone that wants to can test and publish their results on the boards. There is no need to host a site or do anything special, just go do the work and share it and stop waiting for other people to do the work for you..Edited by Martinm210 - 11/25/12 at 6:49pm
