EVBoiler - operational diagram - solar DC water preheating

This operational diagram shows another possibility for installation using the EVBoiler: the DC panels are used for direct water pre-heating. This is especially suitable for systems where you already have some water heating equipment (e.g. a gas heater). By using the solar panels you can pre-heat the cold water (from very cold — to at least somehow warm). This way you can reduce the need for using the energy at your existing (gas) heater. This solution is very good in places with a lot of water consumption, where the solar panels will not provide enough power to make the water fully hot, so they at least make partial preheating.
