No more waiting for the water tank to warm up or running out of warm water halfway through your shower. With this amazing machine, you can have a steady stream of hot water flowing to your faucets or shower without waiting for the tank to warm up. There is a forced exhaust structure that keeps the air safe and clean while and after entering the combustion chamber. There is also a dust net to make sure no dirt gets into the tankless water heater. There is a low water pressure startup, which helps to protect the heater and make it easier to use.
