## Questions & Answers

**Q: Could someone tell me the difference between the SW-38 & the EZ-37 other than price?**
A: Hello,The overall size and performance are the same, but they are plumbed differently internally. When you connect them in an array you can connect up to 4 SW-38's in series. If you need more than 4 panels you have to either connect two or more rows of SW-38 (with each row having up to 4 panels only) or you can use the EZ-37 which is designed such that you can connect up to 14 of them in a single row.Thank You,Heliatos Solar

**Q: I want to feed cold water to one end from a water pump and have warm water come out the other to a sink. In hot sun would this overheat and blow up?**
A: For all solar water heating applications a tank is always required. You are right that without circulation and a tank the water in the panels would overheat. The panels themselves would not blow up because they can withstand very high pressure, but some other part in the system might.Heliatos Solar

**Q: I have a studio with pex loops in the slab - I would like to heat enough to prevent hard freeze. Could I connect several of these units directly?**
A: Hello,Yes they can be connected in series up to 4 panels with a solar pump. To connect more you would have to split them into two banks (2 rows of 3 for instance). The panels in each row could be connected in series, but the rows would be connected in parallel. If you need to connect more than 4 in series you can use our EZ-37 panels (also available on Amazon) which can be connected in series up to 16 panels.Thank You,Heliatos Solar

**Q: would this thermo syphon?**
A: Hello,Yes as long as you have the outlet above the inlet. Inside there is a serpentine tube from one port to the other.Thank You,Heliatos Solar
