Reservoir Raises $8 Million to Deploy Smart Heat Pump Water Heaters
Smart appliance company Reservoir has secured $8 million in seed funding to expand the deployment of its predictive heat pump water heaters, which aim to lower household utility expenses and balance electrical grid loads.
What Happened
Reservoir announced an $8 million seed funding round led by Asymmetric Capital Partners, with participation from Founder Collective and MCJ. The startup was co-founded by former Formlabs chief business officer Luke Winston-Almanzar alongside Gabriel Parisi-Amon and Jake Felser.
The company developed an intelligent heat pump water heater engineered to address both high energy usage and plumbing risks. The newly raised capital will support the installation of units across the Boston area, which serves as Reservoir’s initial market. To streamline distribution and installation, Reservoir operates its own plumbing company rather than relying solely on third-party distributors.
Key Highlights
- Funding and Investors: $8 million seed round led by Asymmetric Capital Partners, alongside Founder Collective and MCJ.
- Energy Efficiency: The integrated heat pump operates nearly four times more efficiently than conventional electric units and five times more efficiently than natural gas alternatives.
- Predictive System: The device spends its first month in a household collecting usage data to train an algorithm, heating water during off-peak hours when electricity prices and demand are low.
- Leak Detection and Protection: Includes an ultrasonic flow sensor that alerts homeowners to plumbing leaks through a mobile app.
- Product Tiers and Pricing: The base “Core” model costs $5,000, while the “Max” version is priced at $6,500, with full installation included. Massachusetts customers can apply a $1,050 state rebate to reduce total costs.
- Advanced Max Features: The Max model includes a mixing valve to prevent pipe freezes during cold snaps, a recirculation valve for instant hot water, and a touchscreen- or app-enabled “party mode” allowing a 50-gallon tank to supply up to 150 gallons of hot water.
- Warranty: All units come with a 10-year warranty.
Why This Matters
Water heaters account for roughly 18% of an average household’s energy budget and represent a primary source of residential water damage. Standard water heaters respond solely to water temperature drops inside the tank without accounting for electricity pricing or grid constraints.
By shifting heating cycles to off-peak periods, Reservoir’s units can help reduce power grid strain at the neighborhood level. According to Winston-Almanzar, the appliance can save typical Boston-area homeowners up to $1,000 annually in energy expenses. Additionally, aggregated units have the potential to participate in utility demand response programs, which offer payments to large power consumers for curtailing electricity usage during peak hours.
What to Watch Next
Reservoir has installed approximately 100 water heaters to date and plans to scale to roughly 1,000 installations in the Boston area by the end of next year. Reaching that deployment milestone would represent megawatt-scale thermal energy storage capacity, paving the way for the company to aggregate its fleet for utility demand response initiatives.
Frequently Asked Questions
How does Reservoir’s predictive heating work?
During the first month after installation, the water heater gathers data on a household’s hot water consumption patterns. The system uses this model to run its heat pump during periods when power grid demand and electricity prices are at their lowest, ensuring hot water is available while minimizing operating costs.
What is the difference between the Core and Max models?
The Core model ($5,000 installed) includes the heat pump, predictive software, and ultrasonic leak detection. The Max model ($6,500 installed) adds a recirculation valve for instant hot water, a mixing valve to prevent freezing pipes during cold periods, and a “party mode” capable of delivering up to 150 gallons of hot water from a 50-gallon tank.
How does Reservoir handle installation?
Reservoir manages installations directly through its own dedicated plumbing company, a model chosen to prevent technology adoption bottlenecks common in traditional distributor networks.
