Water is considered soft if its hardness is less than 75 parts per million (ppm), moderately hard at 75 to 150 ppm, hard at 150 to 300 ppm, and very hard at 300 ppm or higher. Water Category Water Hardness (grains/gallon): S = Soft (1 through 7.5); N = Normal (7.6 through 17); H = Hard (over 17).
Application of softened water treatment equipment in boiler industry A qualified boiler water treatment agent must effectively play the role of scale and corrosion inhibition. Scale inhibition mainly refers to the scale inhibition of the boiler body, and the objects of corrosion inhibition include the boiler body and the pipes through which the

Water softeners are a common piece of pre-treatment equipment for boiler feed water. Water that is too hard quickly scales up the internal components of a boiler making heat-exchange far less efficient and eventually destroying the boiler. Water softeners also significantly reduce or
How to Adjust the Water Temperature of a Hot Water Boiler
Most modern boilers will have a digital dial that allows you to set the output temperature. For combi boilers, the recommended output temperature for the radiators is 75 °C and for the water is between 50 °C and 60 °C. You shouldnt need to adjust these output temperatures as you may alter the boiler
