The Aquinox Heat Pump Buffer Vessel is utilised to add volume to your existing heating system; heat pumps require a minimum system volume to function efficiently. Adding a Heat Pump Buffer Vessel ensures a consistent flow rate and system volume are maintained. A heat pump will keep emitting heat even with no demand, and an Aquinox Buffer Vessel will facilitate the storage of this excess heat for later use. 

We manufacture our buffers from Duplex Stainless Steel for its corrosion resistance.

As the buffer vessel will contain warm water, it will prevent the heat pump from going into defrost mode during cold temperatures as warm water will remain cycling.

If you’re not sure whether your heating system requires a buffer tank (as not all do), or what size vessel would be necessary, we would suggest consulting your heat pump installer and/or supplier for advice.

Having a Buffer Vessel reduces the risk of short cycling, leading to inefficiencies and even damage to the heat pump system, leading to a longer lifespan for the system and the heat pump unit itself.

Our buffer vessels range from 15 Litres to 100 Litres covering most requirements for the heat pump market.

If you require a larger buffer vessel – you can view our range here or get in touch.

Our service doesn’t include recommending the correct product designs for our customers’ jobs, so the effectiveness of their use within a system should, therefore, be determined by a competent installer.
