Features
Hybrid water heaters limit how much water and heat energy are being used. The efficiency or economy setting (depending on the model) only allows water to be heated on demand. If the water demand rises, you can switch to electric setting, which is the least efficient option of the water heater but can deal better with high volumes. In addition, there are a few models that have a vacation mode which allows homeowners to be away for long periods without worrying about wasted water and energy.
