Frequently Asked Questions (FAQ)
-
Q: Is this tank compatible with all air-source heat pump water heaters?
A: Yes, the tank is designed with standard 1" BSP connections and can be adapted to most heat pump models. Please confirm your inlet/outlet requirements with our sales team. -
Q: Can the tank be used for other applications like solar water heating?
A: Absolutely. The multi-layer insulation and 304 stainless steel inner tank make it suitable for solar thermal systems, biomass boilers, or any closed-loop hot water storage. -
Q: What is the expected heat loss per day?
A: With 80mm PIR foam, the heat loss is approximately 0.5-1°C per hour under typical indoor conditions (20°C ambient, 60°C water). Actual performance depends on ambient temperature and tank placement. -
Q: Do you provide a magnesium anode rod for corrosion protection?
A: Yes, a magnesium anode rod is included as standard. We also offer titanium or aluminum anodes as optional upgrades for different water quality. -
Q: What is the maximum working pressure of this tank?
A: Standard working pressure is 0.6 MPa. For higher pressure systems (up to 0.8 MPa), we can adjust the tank design upon request. -
Q: How long does the tank last under normal use?
A: The 304 stainless steel inner tank can last 15-20 years, while the outer shell and insulation remain effective for over 10 years. Regular maintenance of the anode rod will extend the lifespan. -
Q: Can I get a custom color for the outer shell?
A: Yes, we offer RAL color matching for the outer shell. Minimum order quantities may apply for custom colors. -
Q: What is the warranty period?
A: We provide a standard 2-year warranty on the tank body and 5 years on the stainless steel inner tank against manufacturing defects. Extended warranty is available upon negotiation.
