# WaterFurnace

> WaterFurnace is a built-in integration for Home Assistant. It has 69 installs sharing analytics and needs the vendor's cloud.

WaterFurnace is a built-in integration that connects Home Assistant to WaterFurnace geothermal systems through the vendor's cloud. It adds a climate entity and a set of sensors for the heat pump. The sensors cover compressor speed, fan speed, compressor power, aux power, fan power, loop pump power, loop temperature, leaving air temperature, leaving water temperature, room temperature, total power and furnace mode. Setup happens in the UI with the username and password of a WaterFurnace Symphony account. If an older YAML configuration fails to import, a notice appears under Repairs in Settings.
