More homeowners should ask this question! Your water heater is the biggest energy guzzler in your life that completely lacks intelligence. A typical home water heater uses more energy each year than an electric car, making it the second biggest use of energy in the average home (in some homes it is the biggest). On top of its enormous energy use, water heaters are designed to fail at the worst possible moment.

Reservoir uses Thermal Intelligence to balance both comfort and efficiency, making it the only water heater smart enough to integrate both an ultra-efficient heat pump and features like recirculation. Standard water heaters lack the intelligence to add such features without blindly wasting more energy.

Yes! Reservoir has four electric heating elements including an ultra-efficient heat pump. Reservoir will qualify for all heat pump water heater incentives. Read more about the federal incentives here.

Reservoir is able to detect and warn you of leaks in your hot water plumbing system using pressure and ultrasonic flow sensing technology. The temperature sensor array can also predict if your cold water temperatures are dropping to the point where pipe freeze is a risk. Reservoir can even take action to help prevent frozen pipes by using the integrated recirculation pump to warm connected plumbing lines.

Reservoir can run a one time or regularly scheduled Self Clean cycle that heats the tank enough to kill harmful bacteria like Legionella. The integrated mixing valve ensures the output temperature to your faucets stays at a safe level.

Yes! You can get in your shower faster and save a lot of water. Most homes in America waste thousands of gallons of water each year just waiting for the faucet to warm up. Reservoir’s No-Wait Shower warms your plumbing lines without dumping water down the drain.

Reservoir uses electronic corrosion prevention technology that can prevent catastrophic tank failure for decades. Reservoir uses some of the same technology that the maritime industry uses to protect critical components on ships.

You have four modes. Balanced Mode is your everyday setting that automatically gives you plenty of hot water while keeping your energy use low. But we added Party Mode because sometimes you just need a lot more hot water (like when your sister and her three kids visit for the weekend). Use Vacation Mode when you are traveling to save energy and money, while the system is on alert for leaks. Finally, you can use Eco Mode if you prefer to use only the heat pump while turning off all other heating elements and features like No-Wait Shower.

Yes, you can absolutely operate Reservoir without the Reservoir Home app. Use the touch screen on your Reservoir to manage most features. Of course, you will need the Reservoir Home app for power features like syncing with your time of use rates, mode scheduling and monitoring your energy and water usage.

We designed Reservoir with solid body construction to minimize unnecessary noise that you might find in other heat pumps. When Reservoir enables the heat pump for heating, it’s about the same noise level as a dishwasher. You can make it even quieter by enabling lower fan speed, which is about the noise level of a refrigerator. The Reservoir Home app allows you to schedule the use of the heat pump fan (e.g. during the night).

Yes, Party Mode does use more energy, and that’s ok for those times when you need more hot water, like when you have family in town. Our goal is to give you flexibility for when you need it while having the most efficient experience on average throughout the year. We think of it like driving a car. Your day to day driving might be relatively low, but sometimes you need to go on a road trip. And that’s awesome.

We are building Reservoir with the ability to plan electricity use around your solar panel’s energy generation. Depending on your rate structure with your utility, you can even save money by consuming your solar energy on site rather than feeding it back to the grid. We will be adding direct integrations with different solar systems over time.

Reservoir acts like your personal energy trader by planning heating when electricity is cheapest. This is a benefit of a tank of water: you can store hot water until you actually want to use it. And that is why we have industry-leading insulation. Think of it almost like a battery of heat that you “charge” whenever convenient, and you get your hot water when you need it. Use the Reservoir Home app to easily enter your utility rates.

Yes! When using the ultra-efficient heat pump for heating, Reservoir draws heat from the surrounding air to heat water. This cools and dehumidifies the air around Reservoir, which is a big benefit during hot, humid days. This is why Reservoir operates at peak efficiency in the summer. You can also set Reservoir to not cool the space more than you want.

Reservoir is already installed in multiple homes in the Boston area, and we are accepting reservations for wider availability beginning in the fall of 2025. We are starting in our home town of Boston to build the best homeowner experience possible before taking Reservoir across the country.

Reservoir qualifies for all heat pump water heater incentives at the state and federal level. Massachusetts residents, for example, will receive an immediate $750 discount sponsored by MassSave, along with a new $300 New England Heat Pump Accelerator incentive. We will provide you with information to maximize your incentives at the time of install.

Reservoir is a direct replacement for most home water heaters (electric, gas, oil, propane) as long as you have the space and the electric capacity. Reservoir connects to a 240V circuit (the same as a standard electric water heater or an electric clothes dryer).

Yes! Reservoir can be installed on a standard 120V plug until you are able to upgrade your electric panel with a 240V circuit for full functionality. This gives you the flexibility to get up and running immediately in the event of an emergency replacement, while taking your time to coordinate electrical upgrades that will enable all of your heating elements.

Reservoir can be installed in basements, garages, utility rooms or utility closets as long as water and power connections are available and there is sufficient space or ventilation to take advantage of the ultra-efficient heat pump. See the product specs above for dimensions. If Reservoir is installed in a smaller, enclosed space like a utility room or closet, you will need venting or a louvered door to help with air circulation to the heat pump.

Water heating is essential to home comfort. It should be easy to upgrade without worrying about haggling or wondering if you are getting a bad deal. Most manufacturers sell a water heater at an advertised price, but then you need to spend time and energy getting quotes from multiple plumbers to find out what your replacement is actually going to cost you. We decided to bring your water heater purchase into the 21st century (like most other purchases in your life) by making the experience transparent and easy with one no-nonsense price.
