Does anyone have any contacts for purchasing PCM's in Australia or has anyone used them ? I first saw articles about them (5 years ago) when used in a concrete slab to control the temperature and improve efficiency when using in-slab heating. I also recently saw their use mentioned in an article in Sanctuary Magazine. I have tried emails to the company ( http://www.teappcm.com/ ) but with no result.
The site now shows various forms of encapsulation and I read an article some time back (now lost) about using the spheres in a SS Hot Water tank to treble the output. There are a couple of devices on the market that use this phase change principle to store additional energy (eg LATENTO) and I can see great value in any Hot water application for this technology but especially solar generated.
The idea was to see if their inclusion in a slab / HWS could enhance solar hydronics andd cost effectiveness. Greatly appreciate any advice / contacts / information.
