Hybrid Water Heater Sizing Guide

Hybrid water heaters offer eco-friendly heat pumps in combination with electricity for hot water that never stops. They may seem large in size for a standard home, but this is to help keep the water warm with the hot air generally found in your basement, garage, or attic. Homes that are in warm climates, such as San Antonio or Austin, benefit the most from the climate because it will generally warm up their water faster. Hot air comes into the unit, warms the water, and then cool air is expelled into the room.

You will notice when switching from a tank style water heater to a hybrid that hybrid water heaters usually have a larger tank capacity. The hybrid units come in much larger sizes because the heat pump sometimes heats a tank of water slower than tank or tankless electric models. That is because the hybrid water heaters pull hot air from the room first before using electricity.

Hybrid water heaters heat up water quickly when switched to electric mode. However, the goal is to operate your hybrid using the heat pump as much as possible to save on energy costs. Because of this, we generally recommend sizing up your hybrid water heater. This will ensure you have more hot water stored in your tank for use through out the home.
