By solar water heater tubes, do you mean vacuum tubes or something else? If it is a vacuum tube, there is no pad underneath, only a silicone ring on top of the tube. This is a dust ring!
Recommend "Dr. Sun" solar energy and Sancang solar energy (no need for water level probes and solenoid valves). Heating and hot water usage rates are fast in rainy weather, as is after-sales service. The rate is also significantly reduced, saving time and energy. This model only takes 20-30 minutes to heat without sunlight, while a single tank solar water heater takes 2-3 hours.
How! How much water does a solar water heater produce? Suitable
This will exist, because the solar tubes will certainly age after ten years of use, they will expand due to alternating hot conditions et cold, causing the tubes. to explode. Just replace them. Solar energy is generally good! It has a lifespan of 10 to 15 years!
Recommended "Dr. Sun" solar energy, three warehouse models (no water needed)! level sensor probes and solenoid valves), rapid use of heating and hot water in rainy weather and after-sales service. Efficiency is also significantly reduced, saving time and electricity. This model only takes 20-30 minutes to heat without sunlight compared to ordinary single-chamber solar, while a single-chamber solar heater takes 2-3 hours!
It is recommended that the water supply be around 80%, because the water in the solar water heater will boil if it continues to boil on hot days!
Recommend "Dr. Sun" solar power and Sancang solar power (no need for water level probes and electrovalves). Heating and hot water usage rates are fast in rainy weather, as is after-sales service. the rate is also significantly reduced, saving time and energy. This model only takes 20-30 minutes to heat up without sunlight, while a single warehouse one takes 2-3 hours!
