The antifreeze fluid from Vadol is designed to protect the solar water heater from harsh winter conditions. Essential for the smooth operation of the system, it ensures that the water circulating in the collector will not freeze, even when temperatures, especially in winter, drop below zero. This reduces the risk of damage and breakage, preserving the lifespan of your system. It is important to monitor the antifreeze level in the circuit and replace it during each scheduled maintenance to ensure optimal performance.
