Buffer vessels are essentially tanks that contain a volume of hot water. They are recommended by Heat Pump manufacturers to ensure efficient running of the Heat Pump. They achieve this by presenting the Heat Pump with a large volume of water to heat which reduces the amount of Heat Pump cycling. This in turn extends the life of the Heat Pumps compressor and by reducing cycling time reduces running costs.
Direct Buffer Stores are heated by the main heat source only (i.e the Heat Pump) whilst Indirect Buffer Stores enable connections to be made to an additional heat source such as oil or gas (but not solid fuel) as well as the Heat Pump. This is achieved by having a separate coil in the Buffer Store.
From 100L to 2000L and above. We can have any configuration made to your design, i.e. vertical/horizontal, multiple connection points, direct/indirect, coil lengths for indirect units etc.
Domestic Hot Water Cylinders and Buffer Tanks must be considered carefully as part of the Heating and Hot Water system design. Choosing a Cylinder and a Tank that is specially designed to work with the Heat Pump/Biomass Boiler being installed is critical for system efficiency.
