Tankless or demand-type water heaters heat water directly without the use of a storage tank. Heat pump water heaters move heat from one place to another instead of generating heat directly for providing hot water. Solar water heaters use the sun's heat to provide hot water.
Unhook the two hoses going to the heater core. Use a hose clamp to hook a garden hose onto one of the stems from the core. Turn the water on full blast.Run the water through until clear water comes out.nother more effective method involves flushing the entire cooling system, which is probably a good idea if the core is stopped up. Look for a flush kit that installs into the heater lines (Prestone makes a decent kit). Drain the cooling system, then attach a garden hose to the T installed in the heater line.
