Compact pressure solar water heater

It is a kind of close-circulation system, water tanks are joined with the vacuum glass tubes together, which can't be separated, and such system can be installed everywhere there are sunshine, mostly on the roof ( ground / flat / incllined roof), less damage from outside).

We are using small heat pipe sets ( small heat pipe + aluminum alloy fins) inside the vacuum glass tubes to transfer the energy from the glass tubes to the water tanks and warm the water inside directly and quickly ( heat pipes working with very very small start-up temperature), no water circulating inside the vacuum glass tubes, so even one or more tubes damaged, the complete system can work normally.

System working pressure: 0.65Mpa, Max testing pressure: 1.2Mpa, Lowest working temperature: -30C.

All items can be fitted with electric heater as backup( 110V / 220V, 1500W, 50Hz), all with 80C / 110C protection resistance inside.

All items can be fitted with sepcially designed controller, for users to control the system automaticlly.

Have passed the test under EN12976, we are the first one in China who have got the solar keymark certificate based on EN12976.

Profit: 1. High pressure working automaticlly, hot water come out with pressure 2. More efficiency than non-pressure items 3. Can be placed higher or lower, easy and convinency 4. Less maintenance cost after sale 5. Easy to install than the split sytem 6. Longer lifetime 7. Good protection with safety valve + air vent valve 8. All the accessories can be check and replaced easily ( glass tube, safty vavel, air-vent valve, electric heater, etc. ). 9. Can take much more strong wind and snow ( no reflector). 10.

Defect: 1. Water tanks are joined with the vacuum glass tubes together, can't be separated, from appearance you can see the water tanks 2. High efficiency, in hot seasons, steam and hot water come out from safety valve and air-vent 3. Cost is a little higher than the non-pressure system, but much more less than split sytem 4. Max capacity: 220L.
