Aquasystem Expansion Vessels

Antonio Zilio began making expansion vessels and surge tanks in 1972 in Bassano Del Grappa, a beautiful area in Northern Italy well known for innovative engineering technology and the odd fine wine! Today, with his son and daughter the company Zilio is one of the world leaders in producing these units with many boiler and heat pump manufacturers using Zilio for their OEM on board expansion vessels.

From wall hung to floor standing, disc or pot style for hot and chilled mechanical water as well as for potable application. With a vast range from 0.5 litre to 10,000 litres that can cover most  requirements, one of the advantages they offer is a replaceable membrane. This removes the problem of vessel replacement when physical dimension limits access.

Central Heating New Zealand is proud to offer these premium Aquasystem products for our customers. Our stocked range is from 6 litres to 500 litres with other sizes available on request.
