Why Reservoir

Don’t just replace, upgrade.

Why replace what just broke with the exact same thing when you could have a water heater that learns your schedule, detects leaks before they become disasters, and pays for itself in energy savings?

Thermal Intelligence

Learns when you need hot water.

AI-driven setpoint adapts to your household patterns. You stop paying to heat water nobody’s using. That’s up to $800 back every year.

Home Protect

Detects leaks & frozen pipes. Shuts off the water. Automatically.

With ultrasonic flow sensing technology, Reservoir monitors your plumbing in real time. It can automatically shut off hot water to avoid catastrophic leaks, and it can even detect and prevent frozen pipes thanks to advanced controls.

No-Wait Shower

Hot water when you turn on the tap.

Integrated recirculation pump. No waiting, no running the faucet for two minutes while the water heats up.

150-Gallon Virtual Capacity

50-gallon tank. 150 gallons of hot water.

Party Mode activates hybrid heating for back-to-back showers, full dishwasher, guests staying the weekend. It handles all of it.

20-Year Tank Life

Built to last up to 20 years.

Most water heaters fail between 8 and 12. Our electric anode rod actively prevents corrosion to double the life of your tank.

Smart Self-Clean

Cleans itself. Literally.

Automated thermal cycling prevents bacteria buildup inside the tank. No maintenance on your end.

All the control you need from home or anywhere.

Reservoir Adaptive Mode learning your behavior

Set it and forget it.

No app necessary. Let Reservoir do the thinking so you don’t have to. Adaptive Mode learns from your behavior to optimize output and energy use.

Manual control modes on the Reservoir touchscreen

Full control.

Some people want even more control, especially with visitors. And some just want Dad Mode for when your teenager needs to finish that shower.

Schedule Reservoir from anywhere via the mobile app

From anywhere.

Schedule Vacation Mode, even if you’re already at the airport. And feel free to check in just for peace of mind. Direct replacement for most water heaters. In a basement. A garage. Or utility room. But it looks so good you might not want to hide it.

People raving about Reservoir.

★★★★★

We were really on the fence about switching from a tankless gas water heater. I’m so glad I got a Reservoir, I love the instant hot water feature!

We considered three options for our gas water heater replacement: a new gas water heater, an on-demand gas water heater, and a heat pump. The installation process was seamless and was completed in one day. I loved that the pricing included all the electric and plumbing work.

Pricing

Apples to apples on water heater replacement.

Compare Reservoir to a generic heat pump water heater, tankless gas, gas tank, or electric tank. Reservoir’s install price already includes plumbing, removal of your old system, and any Massachusetts incentives that apply.
