While tankless water heaters are designed to provide a continuous supply of hot water, it’s still possible to experience a temporary shortage if the unit is not properly sized for your Mercer Island home’s hot water demands. This can occur if multiple hot water sources are used simultaneously, such as running the dishwasher while someone is taking a shower.
However, compared to traditional tank-style water heaters, the likelihood of running out of hot water is much lower with a tankless unit. To ensure that your Mercer Island home’s hot water demands are met, it’s important to choose the right size of tankless water heater for your household’s usage and consult with a professional plumber or contractor.
