eration, be it gas or electric, is the affect of scaling due to hard water. In a standard water heater, scale will eventually affect the efficiency of the unit, and in the case of a tankless water heater, this factor is more important. That being the case, a water filter is often recommended in a tankless water installation (see Figure 5). This particular filter from Falsken Water Systems of Norco, California, is designed to remove sediment down to 5 microns and employs a water treatment compound to reduce scaling. From a maintenance perspective, a differential pressure gauge on the unit advises the homeowner when it’s time to change the filter cartridge.
