Wait, what’s going on here?

The Heat Pump

Our hyper-efficient heat pump harvests electricity when it’s cheapest and cleanest (see what we did there?). It pulls warmth out of the air, even when it’s cold out.

The Tank

A very-insulated water tank holds just the right amount of heat until you need it - as hot water, or as warmth for your home. Temperatures inside the tank are continuously monitored and controlled. Easier said than done.

The Pod

The Pod tells everything else in the system what to do, and when to do it. All based on real-time data - temperature, rates, emissions…and if friends are staying over, the Pod adjusts for more showers on the fly.

The Air Handler

Hot water safely runs to hydronic coils inside the air handler. A super-efficient fan blows air across the hot coils and, ta-da!, your home is warmed. As are you.

The Air Handler works in homes with forced air. But if you use radiant floors, we’ve got you covered too.

Energy bills your great-great-great-grandkids will be proud of.

Load Shifting

We harvest clean, cheap solar energy around noon and store it as heat in the water tank. People shower and heat their homes in the morning and the evening when the grid is dirtier and more expensive. With Harvest you can use heat and hot water whenever you want, using that clean, cheap energy stored up in your tank.

Harvest Electric Draw (kW)
Electric Grid Emissions (KG CO₂e / hr)
Regular heat pump electric draw (kW)
Emission-slashing
Harvest cuts emissions from home heating ninety percent compared to gas furnaces, and forty percent compared to heat pumps without storage. Since home heating and hot water are around 2/3 of home energy use, this is a really big deal. We’ll put it this way: Harvest cuts more emissions than switching from a gas car to an EV.

Bill-shrinking

These are energy bill reductions for fifteen real homes that replaced gas with Harvest. It’s easy to see why Harvest pays for itself in as little as five years.
