Description
The Zilmet ZHT8-15 is a 2.1-gallon hydronic expansion tank designed to absorb pressure fluctuations and protect closed-loop heating systems from damage caused by thermal expansion. Built to the high-quality standards Zilmet is known for, this tank is an ideal solution for residential and light commercial hydronic heating applications.
Product Overview
Expansion tanks play a critical role in any closed hydronic heating system. As water heats up, it expands — and without a properly sized expansion tank, that pressure increase can stress pipes, fittings, and boiler components. The ZHT8-15 provides a reliable buffer, keeping system pressure within safe operating limits and extending the life of your entire hydronic installation.
