What are Thermal storage or Buffer tanks 

What Are Buffer Tanks and Their Purpose?

Buffer tanks, also known as thermal storage tanks, are crucial components in heating and cooling systems. They store thermal energy in the form of heated water, which can be used later when needed. This helps reduce the cycling of the heat source, leading to increased efficiency and reduced running costs. In hydronic systems like underfloor heating or radiators, buffer tanks play a vital role in maintaining consistent temperatures.

Buffer Tanks in Biomass Boiler Hydronic Systems

In biomass boiler systems, buffer tanks are essential for managing the heat output and ensuring that the system runs efficiently. They store excess heat generated by the boiler, which can then be used when the demand for heat increases. This prevents the boiler from cycling on and off too frequently, which can reduce wear and tear and lower operational costs.

Benefits of Using Buffer Tanks

• Energy Efficiency: By reducing the cycling frequency of the heat source, buffer tanks improve the efficiency of the heating system and reduce energy consumption.
• Cost Savings: Lower energy consumption translates into cost savings on utility bills.
• Extended Equipment Life: Reducing the cycling of the heat source minimizes wear and tear, thereby extending the life of the equipment.

Types of Buffer Tanks

Hot Water Storage for Geothermal and Heat Pump Systems

Buffer tanks are also used in cooling applications, such as chilled water systems, where they store cold water to manage peak loads or variable cooling demands. This helps maintain temperature control and reduces compressor cycles, improving the overall efficiency of the cooling system.

Domestic Hot Water Buffer Tanks

Domestic hot water storage tanks, or hot water buffer tanks, are used with water heaters to handle peak demand volumes. These tanks are available in stainless steel and vitreous enamelled steel, offering excellent corrosion resistance and durability.

Heat Pump Buffer Tanks

When using air source heat pumps, buffer tanks are necessary to store energy for defrosting at low temperatures. They provide the hot water needed to maintain the heating system's operation during defrost cycles, ensuring consistent performance and efficiency.

Features & Benefits of Joule Buffer Tanks

Joule, Geledhill, Telford, manufactures a wide range of stainless and mild steel buffer tanks with various coil configurations. Key features include:

• Large Capacity: Stainless steel tanks up to 3,000 litres and mild steel tanks up to 20,000 litres.
• Coil Configurations: Available with different coil types including pumped high temperature, heat pump, gravity, and solar.
• Versatility: Compatible with air and ground source heat pumps, biomass, and solid fuel heating systems.
• Heat Storage: Excellent for storing heat generated by electrical energy.

Selecting the Right Buffer Tank

• Size: The volume of the buffer tank should be approximately 25 litres of water per kW output of the heat pump capacity.
• Material: Choose between stainless steel or enamelled steel based on the application’s specific requirements.
• Protection: Ensure the buffer tank is adequately protected against corrosion, especially in systems with mild steel construction.

How to Calculate BTUs
To manually calculate BTUs, multiply the total watts by 3.412. For example, if you have 500 watts:

BTUs = 500 watts * 3.412 = 1706 BTUs per hour
