“We've had a fairly positive experience with our Heliodyne solar hydronic system. Eight months into its operation, the Heliodyne componentry has proven to be reliable and just whirrs along. They could improve is the WiFi interface -- you have to connect to the unit's own WiFi transmitter, rather than interfacing via your regular network, which in this case means you need an older version of Windows that can be dedicated to talking to the hydronic system. I just use an old laptop that I keep around for this. Having said all of that, my experience has been that solar hydronic systems are not for the feint of heart. I've had to sort through a number of installation errors (so now I know more about my system than the installers did), and the piping relies on flexible stainless steel piping with o-ring washers that are prone to failure if the fittings are over-tightened. And naturally, if you get a plumber involved in the interface with your system, then he's probably going to over-tighten the fittings -- so in our case we've had a few leaks spring up, and it took some effort to find a source for replacement o-rings (McMaster Carr, look for chemical and heat resistance). Can't blame the leaks on Heliodyne though. We have both a large PV system and the hydronic system. Of the two, the PV is definitely the one that is most painless and seamlessly functions (although we've had a couple of flakey inverters, so it's not like there aren't issues on that side of the solar world as well). But when the sun is shining, it's pretty fantastic to feel the heat coming into the house from the hydronic system, and to watch the heat rise in your storage tanks, and then to know that your teenager's hour-long shower is "free" (assuming you've written off the cost of the system, which is a whole 'nother story).”
