A water heater keeps the hot water stored at a set temperature. However, when you have too many people showering consecutively, or while using the laundry or dishwasher, the hot water could run cold soon. That’s when a Tankless model may be right for your home.
These heat water directly without the use of a storage tank. Just like everything else tankless water heaters have pros and cons. They can give you an endless supply of hot water and save you energy because they don’t have standby losses like conventional water heaters. However, they are limited in the amount of hot water that can be produced at one time and they are more expensive to purchase and install than a conventional storage type water heater.
