Product Details

Can mount heater under a sink in any direction. Low lead and certified for use in potable water applications. Note: Pay careful attention to unit selection. Temperature and volume of water are dependent on the kilowatt rating of heater. The higher the kilowatt rating, the greater the volume of hot water. Heater is not designed to be used as a booster or preheater. Installs without a temperature/pressure relief valve (refer to local codes) close to the faucet or tap to eliminate long pipe runs.
