Anti-scale filter

To protect your heating element, you may want to consider applying an anti-scale filter to make the water less hard. As a result, less or no fouling can occur on your heating element and the lifespan will increase considerably. This is because growth on the heating element ensures that the heat can be transferred more poorly to the water, which could cause the element to burn through and have to be replaced. This filter may be expandable with two additional filters to possibly get other pollution, but this is not necessary and you can also suffice with just the anti-scale filter.
