Single point shower heaters are the most common type of instant heaters in the Phiilippines. They include shower accessories such as the hand shower and the hose that are specifically selected to produce the best flow for the water heater. These are installed in the shower area with cold lines only. When installed, there should be no valve or shut-off mechanism to close the water downstream from the heater. These are also not designed to be installed under the sink.
