Tankless Water Heater How Does It Work Explained
You turn on the shower, wait for the water to warm, and expect the familiar routine: the tank has already heated a reserve, so hot water is ready to travel through the pipes. A tankless system changes that sequence. It doesn't keep a large supply hot all day. Instead, it wakes up when water starts moving, heats that water as it passes through, and shuts down when the tap closes. That difference explains both the appeal and the possible surprises.
