Boşaltılmış Boru Basınçlı Ön Isıtmalı Güneş suyu Isıtıcısı (Solar anahtar işareti sertifikası) / vakum borusu Kompakt Bakır Bobin Güneş suyu Isıtıcısı (EN12975 sertifika)

Evacuated tube Pressurized Pre-heated Solar Water Heater (Solar keymark certificate) / Vacuum tube compact copper coil solar water heater (EN12975 certificate)


Key Points of this Evacuated tube Pressurized Preheated Solar Water Heater with copper coil (Vacuum tube compact thermosiphon pressure solar water heater):
1. Solar keymark EN12975 certificate, CE certificate
2. anti-freezing
Because of all hot water in main tank, the feed tank won't be frozen. It can be working well in -10deg.C. - good performance in rainy & cloudy days
When tap water comes in and out, it will be just 3deg.C less than water in tank. Viz. if 90deg.C in tank, the outlet water will be at 87deg.C after exchanging.
If tank water is 90deg.C, and you catch rainy days, no problem, if you use 50L 40deg.C water per day, you can keep getting such hot water for 15 days!!
The electric heater is only backup, we don't use it anytime practically, except in winter.
3. more capacity
Because the water in tank doesn't be used, in fact the circulation is not only water in the tank but also water in the tube. So for example 300L, actually it has 400L in whole system.
4. no scale, high efficiency
Water in the tank wouldn't be used just to heat the coil, the water in the tank will keep hot and no scale. The vacuum tubes will be kept clean, and system has a higher efficiency than normal system.
5. pressure endurance
The thick of coil is 0.8mm, which can withstand 6-12 bar, and it use tap water directly, live water but not sedimentary water.

Principle of this  Evacuated tube Pressurized Preheated Solar Water Heater with copper coil (Vacuum tube compact thermosiphon pressure solar water heater):
The vacuum tubes absorb the sun's rays and turn the rays into energy, heating the water in the tubes. As the temperature of the water is rising, The density turns slightly, then the hot water in the tubes floats into the tank, and the cold water in the tank goes down to the tubes. Keeping natural cycling like this, the water in the tank will be heated.

The Solar Water heater tank is a non-pressurized tank, and has an opening to the ambient atmosphere. Solar water heater tank should always be filled with water to avoid damage caused by dry high temperature working conditions. The stainless steel our use belong to food grade, and SUS 304 & SUS 316 have better corrosion resistance.
