Stainless Steel 316L Compact Heat Pipe Pressure Solar Water Heater for Mauritius
When the heat pipe warms up, the liquid is quickly heated inside the tube and turns to steam. This steam rises up the tube until it reaches a condenser bulb, and release the thermal energy to water tank

4) T/P valve, a must for pressurized system, to release the extra pressure and hot water and keep safety and service time
316L Stainless Steel Pressurized solar water heater working principle
-Solar radiation is absorbed and converted into heat energy by the selective layer of vacuum tubes
-Heat energy is delivered to heat pipe through aluminum wings.
-Working liquid in heat pipe absorbs heat and vapors,it moves towards condenser and releases the latent heat of vaporization .
-As condenser indirectly contacts with water through a copper cap(Blind pipe),the heat is passed through ti to the water in tank.
-Cold liquid returns to the bottom of heat pipe and repeats the cycle, at the same time, water becomes hotter and hotter.
Start up quickly, heat pipe transfer the heat energy into the storage tank swiftly.
Withstand pressure of max 10bar, can be connected with city water directly, work automatically.
The storage tank and the heat pipe mechanical sealed, the solar water heater can still work even withseveral tubes breakage.
With reasonable design and choose excellent material, the inner tank is without any breakage afterone hundred thousand time’shigh pressure testing.
High density polyurethane foam, well insulation.
Can be installed in series and parallel to be a solar hot water system.
Can be connected with gas water heater and small boiler, also can preheat the water in advance.8. Can be installed in anywhere ( for example, you can install the solar water heater on the ground ofthe garden, and use the hot water on the third floor).
HEAT PIPE ADVANTAGES:
Transfer the heat energy quickly, we use special medium in the heat pipe and it can transfer the heatenergy more than 1000 times faster than copper.
Highly efficient absorber, it increase 20% or more than ordinary solar water heater.
No water and no water scale inside the evacuated tubes, the tubes will not be cracked even ifduring -40 Degree..
Withstand pressure of 0.6Mpa, can be connected with the city water directly.
Can still work even with several tubes breakage. The water will not flow out from the storage tank.6. Can be used in sunny days even if in the extreme cold climate.
PRO” : the new pressurized solar water heater, the cold water inlet connect with city water directly, Can withstand high pressure when it works.(Means if the cold water supply pressure in stable, when open the outlet valve will have hot water in time with same pressure;;)
1.During the storm with lightening, please DO NOT use solar water heater and keep the tank full of water during the typhoon/hurricane.;
2.In the summer, if hot water not much used or water temperature is so high, please take some shade to cover part of vacuum tube to reduce the heating;
This solar water heater can use all day for four seasons; the lifetime is more than 15years; During this period, you can take some simple maintenance service as follows:
1).clean the vacuum tubes
If in lots of dust and dry area( North area), the vacuum tubes will have so much dirty on it, it will reduce the reflecting rate for long time. So you need to clean vacuum tubes at least half year or
one year according to the dirt condition. You can use soap water or washing powder water to help clean vacuum tubes. In the rainy areas, it’s no need to do this.
2).clean the incrustation scale:
If the water temperature is too high, or water quality are not good in some areas, or use the water drectly from ground that includes lots of impurity, all of these will cause lots of scale in the tank this will affect the efficiency of solar water heater. So you need to clean the tank exchange magnesium anode every one or two years. This you must ask professional workers to help do it.
