Uncoated standing buffer tank NIBE 300l insulated UKV 20-300 080013

Heat storage with NIBE UKV 20-300

The NIBE UKV 20-300 buffer tank is a key element of a heating system that allows for efficient storage and utilization of thermal energy. It is an ideal solution for installations working with heat pumps, heating boilers or other heat sources. This ensures stability and independence from momentary fluctuations in energy demand.

This unenameled tank with a capacity of 300 liters, equipped with thermal insulation, minimizes heat loss and ensures high energy efficiency. Its construction allows integration with various heating systems, and durable materials guarantee long-lasting and trouble-free operation.

Construction and application

The NIBE UKV 20-300 tank has been designed with ease of installation and servicing in mind. The removable housing and thermal insulation facilitate transport and assembly, and numerous connections and covers allow for flexible adaptation to specific installation needs.

• Heat accumulation: The tank stores excess thermal energy generated by the heat source, which allows it to be used later, e.g. during peak demand.
• Protection of the heat source: Buffering reduces the frequency of switching the heat source on and off, which extends its lifespan and reduces operating costs.
• Temperature stabilization: Provides a constant temperature of the heating medium, which translates into comfort of using the heating system.
• Possibility of connecting an electric heater: In the event of a failure of the main heat source, an electric heater can be connected as an additional energy source.

Characteristic features

NIBE UKV 20-300 stands out with a number of features that make it a reliable and efficient solution:

• High energy efficiency: Energy class C ensures minimal energy loss.
• Durable construction: Unenameled steel provides corrosion resistance and long-term operation.
• Precise temperature measurement: Three temperature sensor sleeves allow for accurate monitoring of the temperature at different levels of the tank.
• Optimal heat intake: Appropriately shaped heating medium intake nozzles ensure intake of the warmest medium from the upper part of the tank.
• Easy installation and servicing: Removable housing and thermal insulation facilitate transport, installation and any repairs.
• Built-in mechanical air vent: Removes air from the system, improving its efficiency.

The nominal capacity of the tank is 300 liters, the maximum working pressure is 6 bar, and the maximum working temperature is 85 °C. Its overall height is 1655 +15/-0 mm, and its weight is 83 kg.

This buffer tank is an investment in thermal comfort and energy savings – both for professionals involved in heating installations and for end users looking for a reliable solution for storing thermal energy.
