400l MAXI indirect water heater with coil, enameled, rigid polyurethane foam, skay, vertical freestanding: coil surface area 5 m2 26-408100N

DHW heat exchanger for heat pump cooperation

This vertical, freestanding DHW heat exchanger with a capacity of 400 liters is an ideal solution for preparing domestic hot water, especially in systems with heat pumps. The construction with an enameled tank and a large spiral coil with an area of 5 m² ensures efficient heat exchange and rapid water heating. The heat exchanger is adapted for mounting an additional heat source in the form of an electric kit, which increases its versatility.

Construction and application

The tank is made of steel and coated with high-quality EXTRA GLASS® ceramic enamel, which ensures durability and corrosion resistance. Insulation with rigid polyurethane foam minimizes heat loss, reducing operating costs. The housing made of skay (or PVC film) protects the insulation and improves the aesthetics of the device. The large surface area of the coil makes the heat exchanger perfectly compatible with heat pumps, effectively utilizing renewable energy. The possibility of mounting an electric kit allows obtaining a power reserve during periods of increased demand for hot water or in the event of a failure of the main heat source.

Advantages and benefits

• High efficiency: Large coil surface area (5 m²) ensures fast and efficient water heating, especially in combination with a heat pump.
• Durability: EXTRA GLASS® ceramic enamel protects the tank against corrosion, and an optional titanium anode (available separately) extends its lifespan – operating maintenance-free.
• Energy saving: Rigid polyurethane foam minimizes heat loss, reducing operating costs.
• Versatility: The possibility of mounting an electric kit increases the functionality of the device and ensures independence from the main heat source.
• Easy installation: Connections located at the rear facilitate installation and service access, and leveling feet ensure the stability of the device.
• Safety: The heat exchanger has corrosion protection thanks to the enamel and magnesium (standard) or titanium (optional) anode.
• Capacity: 400 liters is an optimal choice for households with an average demand for domestic hot water.
