NIBE VPA 450/300 Cu Double Jacketed Water Heater

Description

NIBE VPA 450/300 Cu is a high-performance, double jacketed water heater and storage tank with a generous water reservoir. The unit is primarily designed for connection to modern heat pumps, but is also excellent for integration with other heat sources. The model has a proven and robust corrosion protection made of high-quality copper, which ensures reliable and long-term function in demanding environments. The spacious design delivers plenty of hot water and creates a stable heating economy in the property.

NOTE! Velltra assures that all NIBE products marketed and sold by us are manufactured in Sweden and contain components of the highest quality, especially adapted for the Nordic market and its challenging climate.

High capacity and stable hot water comfort

With a tank volume of 450 liters and a hot water capacity of a full 550 liters at 40 °C, the NIBE VPA 450/300 Cu also meets very extensive needs for hot water. The accumulator section holds 285 liters in the casing space, which creates an excellent energy buffer for connected heating systems. The double-jacketed construction provides even heat transfer between the heating medium circuit and the tap water, which minimizes temperature variations and provides a reliable hot water supply around the clock.

Minimal energy loss with removable insulation

The tank is enclosed in modern and environmentally friendly insulation that keeps heat loss at an exceptionally low level. To facilitate installation and assembly in tight spaces, the insulation is completely removable. This significantly simplifies handling when transporting through doorways and stairs, without compromising energy efficiency once the system is installed and commissioned.

Flexible connections and immersion heater operation

NIBE VPA can handle an operating temperature of up to 90 °C and is equipped with ready-made sockets for immersion heaters as well as immersion tubes for temperature control and sensors. The option of additional immersion heater operation serves as a safe backup solution or peak heating during extreme cold snaps. The heater can also be connected in series if even larger water volumes are needed, providing a flexible solution that can grow with the property's future requirements.

Swedish quality and warranty

NIBE VPA is manufactured with carefully selected materials to meet strict requirements for durability and performance. Please note that the manufacturer’s full warranty is not applicable for units bought in Sweden and installed outside Sweden.
