How can I connect an air compressor to my pump station to pressure test my solar thermal system for leaks? Our pump station’s fill valve has GHT hose threads on the outside. You can easily make an adaptor using the following three fittings, which can be purchased at your local hardware store or plumbing supply. Schrader valve x ¼” male NPT Reducing Bushing, ½” NPT Male x ¼” NPT Female Hose fitting, ½” NPT male x ¾” swivel GHT female Use Teflon tape on the NPT threads of the Schrader valve and bushing in constructing the adaptor. When attaching the [...]

How can I connect an air compressor to my pump station to pressure test my solar thermal system for leaks?
How should I test my solar thermal system for leaks? After a solar thermal system has been installed, it should be tested for leaks before it is charged with heat transfer fluid. Leak testing should be done with air pressure. Air pressure can detect even small leaks that would be difficult to detect with liquid, because the liquid would evaporate as it leaked. Even tiny leaks are critical, because loss of fluid over time would change the system operating conditions and decrease performance. For more information, watch our webinar on air pressure testing.
My sensor cable is only 4 feet long. How do I wire it from the controller all the way to the collectors?
My sensor cable is only 4 feet long. How do I wire it from the controller all the way to the collectors? First off, when wiring to the collectors, make sure you use the high temp sensor (usually black or red). One end of the sensor cable has the sensor, which needs to be at the hot end of the collector array, and the other end has crimped wires that fit easily and securely into controller slots. So, the best thing to do is cut the sensor cable in half, and use each half where it is meant to be [...]
Yes you sure can. Using the pool as a heat dump in the summer is very easy to do and very beneficial, not only to your wallet but a warm pool makes a happy wife. We have many clients that are doing this very thing with their “extra” energy from the solar loop, especially for solar combi-systems. Here is how you do it: You will need a stainless steel shell and tube heat exchanger, a motorized, three port valve and some extra piping. Ask you sales rep for a schematic to help you. Using the three-port valve on the hot [...]
Well, that all depends but usually 2 workers can install a simple DHW kit and have it fully commissioned within 3 days. There are some cases where only 2 days is required and some days more. Our Heliomaxx kits are designed for simplicity and we expect that you shouldn’t really need more than 48 total hours for a job and could be as low as 32.
Typically, an american average consumption of 20 gallons of hot water per day per person can be used to size systems. There are some variations in that however so we need to be careful about just using rules of thumb. For most of the Sunmaxx TitanPower Flat plates and Thermopower Evacuated tubes will yield about 2 gallons of hot water per FT2 of collector. Therefore, we can say that for a family of 3, we would recommend about 30 ft of collector. This estimate will vary depending on the part of the world you are from. If you live in [...]
