- the valve is used for filling buffer tanks and especially to protect the boiler against low-temperature corrosion up to an output of 150 kW. Consistently maintaining a higher return temperature means higher boiler efficiency, minimises tarring and maximises the boiler's service life. The thermostatic filling valve is suitable for installation on the boiler return, or for filling buffer tanks.
