Engineered for thermal resilience, corrosion resistance, and decades-long stability in demanding renewable energy installations.
Designed exclusively for heat pump systems, our enamel-coated stainless steel water tanks deliver unmatched durability in high-temperature, high-humidity, and chemically aggressive environments. Unlike standard storage tanks, this unit features a fused vitreous enamel lining applied at >850°C — creating a non-porous, inert barrier that eliminates rust, scale buildup, and microbial adhesion over time.
Ideal for OEM integrators, system engineers, and renewable energy contractors seeking long-term reliability without maintenance overhead, this tank extends service life beyond 25 years while maintaining thermal efficiency and pressure integrity across seasonal load cycles.
Vitreous enamel fused to 304/316 stainless steel substrate resists chloride ions, acidic condensate, and glycol-based heat transfer fluids — eliminating pitting and electrolytic degradation.
Withstands repeated thermal cycling from 5°C to 95°C (±200,000 cycles) without enamel cracking or delamination — validated per EN 1487 and ISO 27307.
Pre-configured flange ports, insulation-ready shell geometry, and standardized mounting interfaces simplify integration with air-to-water and ground-source heat pumps — reducing engineering time by up to 35%.
Integrated into domestic hot water (DHW) and space heating loops for single-family homes and multi-unit dwellings.
Serves as buffer and stratification tank in decentralized heat networks serving offices, schools, and municipal buildings.
Paired with solar thermal collectors and backup boilers in low-carbon retrofit projects across EU and North America.

Epoxy coatings degrade above 70°C and are vulnerable to UV and mechanical abrasion. Stainless-only tanks suffer from localized corrosion where weld seams or scratches expose base metal. Enamel provides full-surface, glass-like inertness — stable across the entire operational range of modern heat pumps.
Yes — the smooth, non-porous enamel surface ensures optimal adhesion for mineral wool, polyurethane, or vacuum insulation panels. Flange ports are recessed to avoid thermal bridging when fully wrapped.
Yes — we support OEM port positioning, thread types (G½”, NPT, BSPP), and sensor integration (thermistor, pressure tap) per project drawings.
