Frequently Asked Questions (FAQ)
1. What is the difference between double wall and single wall tanks?
Double wall tanks have an inner and outer shell, providing better insulation, reduced condensation, and enhanced safety against leakage. The 80mm rockwool insulation sits between the two walls, significantly improving energy efficiency.
2. Can this tank be used with a solar water heating system?
Yes, the 300L tank is designed for solar, heat pump, boiler, and electric hybrid systems. It has multiple inlet/outlet ports to accommodate heat exchangers or circulation loops.
3. Is the stainless steel tank safe for drinking water?
The inner tank is made of food-grade stainless steel (304 or 316L), which is safe for potable water. However, we recommend using a corrosion-resistant coating or anode rod for long-term protection.
4. What is the maximum working pressure?
Standard working pressure is 0.6 MPa (6 bar). Higher pressure options are available upon request for specific applications.
5. How long does the insulation last?
Rockwool insulation is highly durable and does not degrade over time like foam. It maintains its thermal performance for the life of the tank, provided it is kept dry.
6. Can I customize the tank size or connections?
Absolutely. We offer OEM/ODM services for capacity, connection types, colors, and additional features such as electrical heating elements or heat exchangers.
7. What certifications does your tank have?
Our tanks are manufactured to comply with international standards. Certification such as CE or ISO can be provided upon request, depending on the destination market.
8. What is the warranty period?
We typically offer a 2-year warranty on the tank. Extended warranty options are available for bulk orders. Please contact us for details.
