The THERMAL-PLUS thermal expansion tank is engineered to protect your closed, hot water system from the damaging effects of thermal expansion. As domestic water heats, it expands, and without proper management, this expansion can lead to excessive pressure, potentially causing relief valve discharge, leaks, or even more serious hazards.
Reliable Pressure Control and System Protection:
THERMAL-PLUS expansion tanks are designed to effectively absorb the expanded water volume, maintaining safe and consistent pressure levels within your water heating system. By accommodating the expansion, these tanks prevent overpressure and safeguard your plumbing system from potential damage.
High-Quality Construction for Long-Term Performance:
Built to last, THERMAL-PLUS expansion tanks feature a durable stainless steel system connection for corrosion resistance. Inside, a polypropylene liner effectively separates the water from the tank shell, while a heavy-duty butyl rubber diaphragm ensures reliable separation between the water and the 40 PSIG nitrogen pre-charge. This robust construction guarantees long-term performance and peace of mind.
Essential Component for Safe and Efficient Operation:
THERMAL-PLUS expansion tanks work in conjunction with a backflow preventer or check valve to ensure the integrity of your water system. By controlling excessive pressure generated by the water heater, THERMAL-PLUS provides an essential layer of protection, making your home’s hot water system safer and more efficient. Invest in a THERMAL-PLUS tank and enjoy worry-free hot water for years to come.
