How quickly can a tankless water heater deliver hot water?
Tankless water heaters heat water on-demand, which means they start heating water as soon as you turn on the tap. However, the time it takes for the hot water to reach your faucet will depend on the distance between the water heater and the faucet. If the faucet is far away from the heater, it may take a few seconds longer for the hot water to reach you. One way to overcome this delay is to install a dedicated recirculation line and recirculation pump however this can be costly.
