That depends on the type of system and the harshness of the water supply. With a Glycol system you will need to replace the fluid in the panels about every 5 years to maintain the performance and longevity of the piping. With a Drainback system, the only thing is to check the sight glass on the side of the 10 gallon drainback tank to ensure proper water level. As with any water supply that is considered "hard" water, scaling may occur, and you will have to drain the system to remove the deposits from hindering the heat exchanger. Luckily the SolVelox comes with accessible water cut-offs to easily clean the system.
