Well, rather then clog up my Greenhouse I figure I'd start this thread
I should have done this before
Here is the greenhouse thread with info
DIY greenhouse - $30 maybe
Recap: Picked up (2) 4x12' solar water panels for free off craigslist for free
Connected them to my Hot Tub w/515gph pump beginning of May
Tub was at 56 - shut off, within a few days it was up to 104
I left it running too long one day & it hit 114
So now I pulled one 4x12 panel off & installed it on the hot tub (un-used) out by the pool
Filled the water thru the panel to warm it up, then started to recirc water once full
Temp went from 55 (hose temp) to 75 the 1st day
Weather Temps tomorrow are supposed to be 90, good heating day
So hoping the 2nd tub will be over 90
I also picked up 4 smaller panels & they are being used to heat the 16x32 inground pool
Today I connected my old solar pool panels & water coming out was 82
Pool has climbed from 58 to 65 since the small panels were connected
Hoping to get over 70 tomorrow
Eventually 2 of the smaller panels will be used for a Solar hot water system for the house
Oh, electric bill dropped a LOT since the tub was shut off
We are using the hot tub a lot more now that the heat is free
