Do tankless hot water heaters take longer to heat up?
You may have to wait longer in the case of gas tankless water heaters, even though we’re talking about seconds and not minutes. Basically, tankless units need 15 seconds to heat water to the set temperature, but you may still have to wait longer than that until hot water comes out of the faucet/showerhead.
Why are there problems with tankless water heaters?
Because tankless units only heat water as it’s needed, running too many hot water appliances at the same time could mean the unit just can’t keep up.
How long does it take for a tankless water heater to heat up?
Once that cool water is flushed out, heated water comes through, however, it can take between a few seconds and a minute depending on the distance between the heater and the tap. Tank-style heaters don’t produce hot water instantly either but since they have a supply ready to go and don’t need to kick on, it reaches the outlet more quickly.
What is the minimum flow rate for a tankless water heater?
You see, every tankless water heater has a minimum “flow rate”— which is the minimum amount of water, measured in gallons, that the tankless unit needs flowing through it every minute (gpm) to produce hot water.
How much money can you save with a tankless water heater?

Where does the hot water come from in a tankless water heater?
Before it fully warms up and starts heating the water, you get a short run of cold water. Then, once the heat exchanger heats up, you get a steady flow of warm water. So where does the initial blast of hot water come from?
Why is there a gap in my tankless water heater?
Although tankless water heaters are also called “instantaneous water heaters,” they still take time to heat water, so after the trapped water was used up, you were left with a gap of unheated water. The further your water has to travel from the water heater to its destination, the more noticeable the gap.
