Fist bump our
heat pump.
Our hyper-efficient heat pump uses grid electricity when it’s cheapest and cleanest. Good for you, good for the planet.
Incentives?
Oh, just a few.
Combo heat + hot water + storage + air conditioning means you’ll qualify for incentives your gas appliances couldn’t even dream of.

A tale of two energy nerds.
When Jane and Pierre’s HVAC quit working in 2018, they went to work fixing everything about home comfort.
Pays for itself.
Cheaper HVAC options totally exist. But none will save you (or Earth) more than Harvest.
Works with your stuff.
Already have radiant heat? Smart thermostat? Ducts? A/C? Harvest will be right at home.

Is Harvest a heat pump? Yes, and.
When you’re looking to make your home comfier, tackle high energy bills, take advantage of efficiency rebates, and/or make your solar power more impactful for your home, you’ll probably end up bumping into the same thing over and over again: heat pumps.
We often get the question: is Harvest a heat pump system? The answer is yes, and.
A heat pump is the engine of any Harvest system. But Harvest adds a brain and a battery to a heat pump, which makes it smarter. And cheaper.
Allow us to explain - it might take a minute, but we’ll get there. Promise.
What’s an air-to-water heat pump?
A heat pump is a device that moves heat around. For example: your refrigerator has a heat pump that moves heat from the inside of the fridge to the outside. That makes it cold inside the fridge.
Air-to-water heat pumps (the kind of heat pumps we like the most) are amazing. They move heat from the air (usually outside the home) into water (usually inside the home, in an insulated tank). Even when it’s cold out. Not only are they hyper-efficient in how they use and store energy to heat your water (and your home), but right now, they’re kind of all the rage because of the incentives they bring.
Harvest uses the most efficient air-to-water heat pump on the market, and Harvest is cheaper to install than most other HVAC options, especially those with air-to-water-heat pumps included.
When we talk about “heat pump water heaters,” technically we’re referring to air-to-water heat pumps, but the difference is, they are devices designed to heat potable water, whereas typical air-to-water heat pumps heat non-potable water for heating, not for drinking or showering.
The difference is, generally, that a heat pump water heater refers to a product that heats water for domestic uses, whereas an air-to-water heat pump water for heating and cooling purposes.
Harvest, though, is not typical: we use a heat pump water heater as an air-to-water-heat pump for heating and for domestic hot water.
What’s the most eco-friendly air-to-water heat pump?
The most eco-friendly air-to-water heat pump is the SANCO2. That’s because the most energy efficient air-to-water heat pump is the SANCO2. And efficiency = eco-friendliness. Because when you use less energy, you decrease the amount of fossil fuels needed to run the electric grid. And when you use fewer fossil fuels, you reduce the amount of carbon pollution released into the environment - pollution that’s bad to breathe and also causes long-term global heating.
Mind if we gush about some SANCO2 specs for a moment? It has the highest first-hour rating of any residential electric water heater, the highest real-world efficiency (80% savings over electric resistance water heaters and 40%+ over an integrated heat pump water heater), and it uses the most environmentally-friendly refrigerant on the market: CO2, which is right there in the name.
Perhaps it won’t surprise you that a SANCO2 air-to-water heat pump is the engine of any Harvest system.
What rebates are available for air-to-water heat pumps?
A Federal 25C tax credit is available for up to $2,000, and a recently-launched TECH Clean California air-to-water heat pump (AWHP) program provides a $2,500 incentive for air-to-water heat pumps. For up-to-the-minute information about rebates available in your area, we suggest a home assessment through QuitCarbon (it actually works, and an actual human will work with you!), and/or using Rewiring America’s incentive calculator to learn more.
Can an air-to-water heat pump do home heating and air conditioning?
Why yes, yes they can. Harvest uses an air-to-water heat pump to heat the water you use in your kitchen or shower, and uses the heat stored in the hot water tank to heat the rest of your home - and it’s available today. We use an air-to-air heat pump to cool your home.
Some companies have begun working on air-to-water heat pump chillers that cool water - awesome, but not widely-deployed yet. Expect to see a lot of innovations in air-to-water-to-air cooling in the next couple of years.
Does an air-to-water heat pump work with a mini split?
An air-to-water heat pump works fine in the same home as a mini-split, but it doesn’t really work together with a mini split.
A mini-split is a kind of air-to-air heat pump: the heat pump unit itself lives outside, and then the “head unit” (the thing that the cold air shoots out of) lives inside your room.
So: no problem to have both an air-to-water heat pump and a mini split in the same house, but they probably won’t be connected.
Harvest is an example of an integrated heating system with a split heat pump water heater: it replaces your gas-fired furnace with a water-fired furnace. Where’s that hot water come from? You guessed it: the SANCO2 split air-to-water heat pump.
Harvest works great with central HVAC, which is what most people already have installed in their homes - it really only requires one system for a home, whereas mini-splits usually require one system per room. That can get expensive, especially when you have a lot of rooms - and mini-splits usually don’t do a lot to heat or cool “in-between” spaces like hallways and bathrooms.
What’s the difference between an air-to-water heat pump and other hot water systems?
An air-to-water heat pump is much more efficient than old-school resistive water heaters. Resistive water heaters are the equivalent of rubbing two sticks together to make fire: they take a lot of electrons and bump them up against one another, which works, but is super inefficient.
Air-to-water heat pumps are also way better than gas-powered hot water tanks or tankless systems, because, well, they don’t use gas - a non-renewable resource that heats the planet and causes nasty air pollution.
Efficient AC and heat pump rebates: a killer combo.
Harvest's revolutionary HVAC + hot water system is uniquely eligible for incentives around $12,500 (sometimes even more). And that's before you start saving on monthly bills.
The future of
home comfort. For all four seasons.
The best heat pump cooling and heating system. For planet and pocketbook.
Our hyper-efficient heat pump knows what time it is. Harvest pulls energy off the grid when it's cheapest and cleanest, and stores it as hot water. You use that heat when you want it. You'll pay less, too.
