TW – Bolt-On Water Heater
These Incoloy 800 Sheathed Heaters for most Australia & New Zealand made hot-water heaters. Corrosion resistance sheathed elements, eliminated most plated and Un-plated copper type of Bolt-on elements.
This type of element is manufactured especially for storage tank water heating system.When different metals are in close proximity to one another in solution, corrosion activity will take place causing the least superior metal to corrode. Therefore, TW had produced the element using Incoloy 800 sheath in areas having hard water conditions. This situation being acceptable as Incoloy is a metal having a very high nickel content to reduce the corrosion process.
