Harvest is a whole-home heating, cooling, and hot water system that reduces emissions by about 90% and cuts heating and hot water energy costs by 30% on average.

Harvest integrates an ultra-high efficiency electric heat pump with thermal energy storage to create a smart thermal battery system. It delivers home heating, cooling, and hot water, directed by the Harvest Pod, which continuously accounts for energy costs, grid emissions, changing weather, and your household's comfort patterns. The system charges during times when electricity is cheapest and cleanest, then delivers heating and hot water whenever you need it — without drawing from the grid during expensive peak hours.

Harvest offers three different configurations depending on your home’s needs and existing HVAC infrastructure. All systems include the core smart thermal battery: the Harvest Pod, a water tank, and a high performance air-to-water heat pump.

Harvest Classic is our flagship heating and hot water offering, serving up top-tier comfort and exceptional efficiency for homes with ducting that don’t require cooling.

Harvest Open pairs our thermal battery with an air-source heat pump for ducted homes that require cooling or have higher heating loads.

Harvest Radiant brings the efficiency of our thermal battery to homes with radiant heating, working with a wide range of modern hydronic systems.

A heat pump is a highly efficient heating and cooling appliance that moves heat rather than generating it by burning fuel. In winter, it extracts heat from outdoor air and transfers it inside your home. In summer, it reverses — pulling heat out of your home and releasing it outside, just like an air conditioner. Because they move heat rather than create it through combustion, heat pumps are typically 3–5 times more efficient than gas furnaces. Harvest uses one of the most efficient heat pumps available, paired with a thermal battery to maximize those savings.

Think of it like a home battery — but instead of storing electricity through chemical reactions, Harvest stores heat in water. During the middle of the day, when electricity is most abundant, clean, and affordable, the system charges by heating water and storing it in the tank. That stored heat is then available to deliver space heating and hot water on demand — without drawing from the grid during expensive evening hours.

Compared to electrochemical batteries, water is simply a cheaper and more durable way to store thermal energy — delivering the same load shifting benefits at a fraction of the cost.

The Harvest Pod is the brain of the system — a wall-mounted controller about the size of a large shoebox that continuously manages when and how your system operates. It accounts for real-time electricity prices, outdoor air temperature, local weather forecasts, and your household's heating and hot water usage patterns to determine the optimal time to charge the thermal battery. You can monitor your system and adjust settings through the Harvest Home app from any device on your home network.

A time-of-use rate plan varies the cost of electricity by time of day — charging less during off-peak hours (typically midday) and more during peak evening hours. Harvest is designed to work hand-in-hand with these plans, automatically running during low-cost periods and minimizing electricity consumption when rates are highest. While Harvest delivers savings on any rate plan, pairing it with a time-of-use plan maximizes those savings. Your installer can help you evaluate the best plan for your situation.

Harvest is designed to work with ducted HVAC systems and radiant heating — which covers the majority of homes. If your home has neither, it may still be worth a conversation, particularly if you're already considering an upgrade to your heating system.

Beyond that, Harvest takes up roughly the same footprint as a conventional heating and hot water system. The outdoor heat pump unit is about the size of a standard air conditioner, the storage tank replaces your existing water heater, and the air handler slots in where your furnace was. The Harvest Pod mounts on the wall next to the tank.

Not exactly. Mini-splits are excellent, efficient systems — but they're typically ductless, mounted directly on interior walls, and don't include energy storage. Harvest is designed for homes with existing ducted HVAC or radiant heating, and adds a thermal battery that mini-splits don't offer. If you're deciding between the two, the right answer usually depends on your existing infrastructure — something we're happy to help you think through.

Yes. Harvest works seamlessly with rooftop solar — when your panels are generating power midday, Harvest can use that electricity to charge the thermal battery. But you don't need solar to benefit. Even without panels, Harvest draws from the grid during midday hours when solar generation across the broader grid makes electricity cleaner and cheaper. Either way, you're capturing the most affordable, lowest-emission energy available.

Almost never. The heat pump requires a 15-amp, 240-volt circuit, and the air handler and Harvest Pod run on standard 120-volt circuits — the same as most household appliances. If you're adding cooling, a dedicated 240-volt circuit is required. Your installer will confirm your panel's suitability during the site assessment.

In most homes, Harvest fits comfortably within the footprint of your existing heating and hot water equipment. The typical storage tank (28" diameter, 64" tall) fits in most closets, garages, or mechanical rooms in place of your existing water heater. For forced-air systems, the air handler is the size of a standard furnace and typically installs in its place. The outdoor heat pump unit (35" wide × 26" high × 14" deep) can be placed in a side or backyard or mounted on an exterior wall. The Harvest Pod mounts on the wall next to the tank.

Every home is different, so we start by understanding your home's specific heating, cooling, and hot water needs. Completing the Get Harvest form kicks off that process — we'll evaluate your requirements based on your home's size, layout, insulation, and local climate. From there, a Harvest-certified contractor will conduct a site visit to confirm the right system configuration and provide an accurate quote. You won't need to figure any of this out on your own.

Harvest has an established installer network throughout California, Washington, and Oregon. If you're outside these areas and interested in Harvest, reach out to us at sales@harvest-thermal.com — we can often work with qualified local installers to get the job done.

Most heat pump systems provide space conditioning or water heating — Harvest does both in one integrated system. The key differentiator is the thermal battery: rather than running your heat pump whenever heat is needed, Harvest charges during the middle of the day when electricity is cheapest and cleanest, then delivers heating and hot water on demand from stored energy.

That translates directly to lower bills — 30% lower heating and hot water costs on average, and up to 45% depending on your rate plan. It also means you can fully eliminate gas from your home without sacrificing comfort or control.

Actual savings depend on your home's size, insulation, local climate, and rate plan. The 30% average reflects a wide range of homes and usage patterns — some customers save more, particularly those on time-of-use rate plans. Your installer can model what to expect for your specific situation.

Yes — and in many cases Harvest qualifies for higher rebates than standard heat pump systems, because it provides the functions of both space conditioning and water heating.

Available incentives vary by location and typically stack across multiple programs — state electrification rebates, local utility incentives, and county or city programs. Incentives change frequently, so get in touch and we'll walk you through exactly what's available in your area.

Payback depends on your installation costs, available incentives, energy usage, and local electricity rates. That said, if you're already facing an HVAC or water heater replacement, the comparison changes significantly — in many cases, Harvest is competitively priced against installing a standard heat pump and heat pump water heater separately, making the incremental cost of upgrading to Harvest quite small.

Your installer can walk you through a payback estimate based on your specific situation.

Every home is different, so costs vary based on size, existing infrastructure, ducting quality, and available incentives. Rather than quote a number that may not reflect your situation, here's what we can say with confidence: Harvest qualifies for more rebates than most comparable systems, and delivers 30% lower heating and hot water bills on average — both of which meaningfully affect the total cost picture. Get in touch and we'll work through the numbers with you.

Yes. All Harvest installers have access to financing programs designed specifically for home energy upgrades. These are typically unsecured loans, meaning no lien is placed on your home and your property is not used as collateral. Your installer can walk you through available options and help you find the best fit for your situation.

Loan terms typically range from 3 to 15 years depending on the program and lender. Longer terms mean lower monthly payments — your installer can help you find a term that works for your budget.

Yes. There are a couple of ways to approach this. Some customers factor expected rebates into their financing upfront to reduce the loan amount and monthly payments. Others finance the full amount and make a lump-sum payment toward the principal once their rebate is received — many lenders will re-amortize the loan at that point, lowering your monthly payment going forward. Your installer can help you understand what rebates are available in your area and how to factor them into your financing plan.

Home improvement loans are generally unsecured and tied to you as the borrower — not the property — so the loan doesn't automatically transfer with the home. You would typically pay off the remaining balance at closing, similar to any personal loan.

Installation typically takes 3-5 days, depending on the scope of work and your home's configuration. Your installer will give you a more precise timeline after completing the site assessment.
