Non pressure solar water heating system whose full name is directlyinserting type full glass vacuum tube solar water heater, can’t bear pressuredue to the O-ring seal between vacuum tube and water tank. It is the mosteconomical type of solar systems for hot water application. This solar water heater shouldbe used in the non pressure situation, and it relies on the natural circulationof water between the tube and the tank. There are inlet/outlet pipe andoverflow pipe under the tank. If the tank is filled with water, the water willflow through the overflow pipe and warning message is sent, also, the waterfeeding valve needs to be turned off. When using this product, the hot waterwill flow through the inlet/outlet pipe because of the gravity effect, and atthis time, the overflow pipe is mainly used to supply air. There iswater in the vacuum tube, thus the water in the tank will spill out under thecondition that one tube is broken. In addition, electric heater can beinstalled to guarantee the hot water supply when it is rainy or cloudy.
The JNNP series of non pressure solar water heatingsystem has more than 10 models including JNNP-47-1500-15,JNNP-47-1500-18, JNNP-58-1800-12, and JNNP-58-1800-15, etc. Among theseproducts, the minimum aperture area is 1.48m2, while the maximum valuecan reach up to 4.14m2. In addition, JNNP-47-1500-15 has the smallest size, 0.42m3 for 100L, and0.43m3 for 130L, respectively. JNNP-58-1800-30 takes up a volume of0.99m3, and it possesses the biggest water tank which can contain300L water.
