Product Usage

We recommend Balanced Mode for day-to-day operation, which offers a blend of efficiency with adaptable hot water capacity. For temporary changes in water usage, we recommend shifting to Party or Vacation Mode.

For more information, see page 6 of the Quick Start Guide.

You can enable smart recirculation for Reservoir to automatically warm your shower based on your predicted schedule. You also have the option to warm your shower by clicking the button on your phone app. 

This will depend on your house and the distance of your shower from your Reservoir. Typically, it will take 30-90 seconds to warm your shower.

Yes! For more information, see the Quick Start Guide.

Recovery time depends on the mode in which your Reservoir is set and how much hot water you need. Balanced Mode takes about an hour to heat a full tank, with slightly longer times during the winter. Similarly, Party Mode takes 45 minutes to an hour. Eco Mode will take 4-6 hours.

Self Clean helps prevent legionella bacteria by regularly heating the tank to a level that kills it. Self Clean is not necessary for the maintenance of your Reservoir. Enabling the feature will schedule your unit to automatically clean periodically

We recommend using one-time Smart Clean in special instances, such as after not using your water heater in over a week or the unit has been stored for under 110° Fahrenheit. Reservoir automatically performs this when enabled, but you can also run the cycle yourself.

Reservoir requires a 240V 30A electrical circuit, which is the same type of power used by appliances such as dryers or ovens.

If your home already has an electric water heater or heat pump water heater, the existing electrical circuit usually works without any changes.

If your home currently uses a gas, propane, or oil water heater, an electrician will typically need to install a new 240V circuit from your electrical panel to the Reservoir unit.

This is a common upgrade and usually straightforward for a licensed electrician.

Typical Electrical Requirements

Reservoir requires:

• A 240V dedicated 2-pole 3-wire circuit

• A 30A double-pole breaker in the electrical panel

• Proper wiring run from the panel to the unit location. For short runs 50-70’ from the panel, this is typically 10AWG conductors - USE COPPER CONDUCTORS ONLY.

Reservoir will confirm the breaker and wiring requirements during planning (with consultation from a licensed Electrician).

In some  cases, a home's electrical panel or electrical service may already be close to its maximum capacity. This could in simple circumstances be due to a lack of physical real estate in the panel to add an additional circuit breaker, or in others finding that the total electrical load / demand exceeds what is currently provided by the utility to the building (“electrical service”). Depending on your home, an electrician may recommend one of the following:

1. Load “shedding” or load management device (most common solution)

A small device  can automatically limit the total load demand by enabling or disabling  major loads on the panel are able to run - e.g. disabling the EV charger when the oven is on.  . This allows the system to operate safely without requiring an  electrical service upgrade.

2. Panel upgrade

If the panel is full or undersized, the electrician may upgrade or add an additional panel to create the real estate to add more additional circuits

3. Service upgrade (least common)

In older homes with very limited electrical service, the utility connection and main panel may be upgraded to increase total capacity.
