Buffer tank 300l BT300 29050

Buffer tanks – the key to efficient heating

Buffer tanks are devices used to store hot water or other heating fluids from various sources – central heating boilers, solar collectors, or heat pumps. Their main task is to stabilize the operation of the heating system, balancing the difference between the power generated and the heat demand. This solution is particularly useful in systems with irregular heat demand or using variable energy sources.

A 300-liter buffer tank, made of black steel sheet, is the heart of the heat accumulation system. The durable construction guarantees long-term and trouble-free operation. Thermal insulation made of polystyrene foam (70 mm) or polyurethane foam (100 mm in the BT500 model) minimizes heat loss, increasing the energy efficiency of the entire system. The outer shell made of steel sheet coated with powder paint (BT220 and BT300) or skay material (BT500) provides an aesthetic appearance and protection against corrosion.

Construction and application

Buffer tanks are designed to operate in a vertical position and are equipped with top and bottom covers made of ABS plastic. The maximum working pressure of the tank is 0.3 MPa, ensuring safe operation in standard central heating installations. They are ideal for cooperation with various heat sources, allowing the integration of several heating systems into one coherent system. This allows for effective use of excess heat and reduced operating costs.

• Heat accumulation: Storing excess thermal energy generated by the boiler, heat pump or solar collectors.
• Stabilization of installation operation: Balancing the difference between generated power and heat demand, which translates into a longer boiler life and more comfortable use.
• Protection against overheating: Preventing the installation from overheating in case of excessive heat production.
• Possibility of integrating various heat sources: Combining different heating systems into one coherent system, which increases flexibility and energy efficiency.
• Reduction of operating costs: Optimizing fuel consumption and lowering heating bills thanks to efficient use of thermal energy.

It is important to remember to use an expansion vessel of appropriate capacity (see manufacturer's tables) and a 3 bar safety valve for the correct operation of the system.
