If you're not pre-filtering, this is actually worse with a tank type water heater than tankless. The sediment and minerals in your well water will all settle at the bottom of the tank creating a layer of insulation between the heating element and the water, lowering efficiency considerably. I'd install a set of 20 and 5 micron filters after the pressure tank and before the heater.
