At times it can be hard to fill a bathtub with a tankless unit. With tankless heaters, greater the flow rate of the water the decrease the temperature rise due to the fact the water spends much less time in the heater. With a bathtub you normally turn on the water complete blast so it does not take also lengthy to fill the tub. Normally the faucet at the tub will have the highest flow rate of any fixture in your household, generally 7 gallons per minute or a lot more.

When you want hot water you press a button and the cooled off hot water in the hot water piping gets pumped back to the inlet of the heater, and when the actual hot water reaches the fixture the pump shuts off. That way you get your hot water more rapidly than running the faucet, you never run any water down the drain even though you wait, and you don’t fill the cold water line with hot water. You save time, water, and revenue. Standard savings can amount to more than 15,000 gallons per year for a family of four.
