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.
First, find the pressure of the water going into your water heater by attaching the water pressure gauge to your water heaterâs drain valve at the bottom of the tank (the same place youâd attach a hose when you flush your water heater). Open the drain valve all the way.
