Solar Collectors and Supplies

We offer vary size high efficiency  pressurized evacuated heat pipe solar collectors for residential and commercial hot water application, and seeking distributor and local dealer for our serious products.

DIY Plans of Solar Water Heat System for Cold Weather Area

Four plans are described  in this manual, it is easy to follow step by step with a large amount of pictures, no plumbing background is required, most of parts are available in local store, P1(plan1) is the foundation of system for update late, also works itself. You can easily to update to P2, P3 and P4 anytime with a little effort. Hot water volume capacity is unlimited based on P1 design. The material costs from P1 to P4 are between $950 and $2500, P5 is for commercial application (e.g. restaurant, laundry, and hotel) or residential radiant floor, the cost is case by case. Please see the table for comparison of plans.

Comparison of Plans of DIY Solar Hot Water System:

Plan: Close glycol anti-frozen system

Pump: I=Iron, B=Bronze or Stainless steel

Collector: 16 evacuated heat pipe tubes, 20 sqft.

Controller: DTC (differential Temperature controller), T (Timer)

Heat exchanger: CPH (copper pipe homemade), PHE (plate heat exchanger)

Tank: regular electric water heater, 50-80 gallon, new 80gallon is around $450, a non-pressured homemade tank can hold over 200 gallon hot water, material will cost around $200-300.
