Choose the sustainable heating and cooling solution that protects the environment while saving you money.

Year-round comfort

Heat pumps are the most efficient way to heat and cool your home.

Instead of generating heat or air-conditioning, air-source heat pumps like the Stash Energy Heat Pump draw heat from the outside air during the heating season and reject heat outside during the summer cooling season.

Heat pumps are much more efficient than other types of heating and cooling systems like window AC units, heating oil furnaces, or baseboard heaters – and helps you reduce your power bill year-round.

Stash Your Energy with Thermal Energy Storage

Energy storage systems like the Stash Energy Heat Pump allow homeowners to store energy during off-peak hours (like when we are sleeping) for use during peak times (like when we all wake up) when electricity is more expensive for the utility to generate.

Stash Energy will help you get enrolled in your utility’s demand response program or time-of-use rate so you can start saving.

Set It and Forget It

Schedule when you heat or cool your home.

With the Stash smart thermostat and mobile app, set your home's comfort level to fit your schedule.

Without affecting your home's temperature, your electric utility can control the thermal energy stored in the Stash Energy Heat Pump to reduce your on-peak costs when you heat or cool your home.
