Buffer Vessels

A buffer vessel, also known as a buffer tank, plays a crucial role in Air Source Heat Pump (ASHP) installations. Here are some of the key benefits:

  1. System Efficiency: Buffer vessels can improve the efficiency of the heat pump system by reducing the number of start/stop cycles. This is particularly beneficial in systems where the heat demand is lower than the minimum output of the heat pump.

  2. Preventing Short Cycling: Short cycling can cause wear and tear on the heat pump’s compressor, reducing its lifespan. A buffer vessel helps prevent this by storing excess heat produced by the pump, allowing the system to run for longer, more efficient cycles.

  3. Meeting Variable Demand: Buffer vessels can help meet variable heat demand by storing excess heat when demand is low and releasing it when demand is high. This can be particularly useful in systems with underfloor heating, which typically have a slower response time.

  4. Integration with Other Systems: In systems that incorporate multiple heat sources, a buffer vessel can act as a ‘thermal store’, allowing seamless integration of the different heat sources.

  5. Reducing Noise: By reducing the number of start/stop cycles of the heat pump, a buffer vessel can also help reduce noise levels, contributing to a quieter operation.

Remember, the size and necessity of a buffer vessel can depend on several factors including the type and size of the heat pump, the heating system it’s connected to, and the specific heating requirements of the building. It’s always best to consult with a heating professional when designing and installing an ASHP system.
