The EXTRAVAREM LC is a premium expansion vessel engineered specifically for potable hot water applications. Unlike standard heating tanks, the LC series is built to handle the constant flow of fresh, oxygenated water without corroding, thanks to its high-quality stainless steel flange and specialized sanitary membrane.
In a domestic hot water system, water expands as it heats up. Without an EXTRAVAREM LC vessel, this expansion causes the safety valve to drip and puts unnecessary stress on your boiler or water heater. By installing this tank, you balance the pressure, save water, and protect your plumbing infrastructure.
