Water heaters and calorifers

Why does the DR-SG contain an anode?
The Dorchester DR-SG features an electrical anode to provide enhanced protection against corrosion. While the unit's stainless steel construction offers significant resistance to corrosion, the anode acts as an additional safeguard, especially in areas with challenging water conditions. This proactive measure helps to extend the lifespan of the water heater and reduce maintenance needs.
What effects can soft water have on a hot water product?
Soft water has a low mineral content, which means it is less likely to form limescale deposits. However, it can be more aggressive towards certain materials, leading to an increased risk of corrosion inside hot water vessels and pipework.
This is where stainless steel products offer a significant advantage. High-grade stainless steel, such as 316L austenitic stainless steel used in Hamworthy Heating products, provides excellent resistance against corrosion in soft water environments. Stainless steel also reduces the need for protective linings or anode replacement, helping to lower maintenance requirements and extend system lifespan.
