[QUOTE="roys, post: 324922, member: 5044"] Hi OnOff, The panels are each about 2.4M x 1M, they are designed to cut out when it gets above 70 deg C ish or below 5 deg C ish, it does this by a drain back system where the glcol mix is drained back it its storage 'flasks' in order to protect the system from overheat or frost damage. I should never see the temp much above 70 deg C, just checked it just now and the system is shutdown due to this. This solar thermal feeds a coil in the 200L hot water cylinder, there is a 2nd coil in the hot water cylinder which is fed from the log burning stove but that was last on about 2 months ago.
