12. Can I fill a hot tub with a Tankless Water Heater?
Sure you can! A Tankless Water Heater is capable of supplying endless supply of hot water. However, larger the units, lesser the time they will take to fill a tub of any capacity. Although, it is important to understand that some tubs draw water at high flow rates. This can be sorted out by limiting the flow so that the heater can sufficiently provide the water needed.
