Enviro Power

What Enviro Power does

Enviro Power, LLC is a Connecticut-based energy technology company that designs and commercializes the SmartWatt Boiler, a drop-in replacement boiler with an integrated micro combined heat and power (mCHP) generator. The system uses a closed-loop, radial micro-steam turbine housed in a patented dual-condensing (dual-fluid) combustion chamber to convert heat normally lost in conventional boilers into usable electricity via a Rankine cycle, achieving nearly 98% HHV heating efficiency while generating up to 6 kW of on-site electricity. Available in 5 kW residential and 6 kW light-commercial variants, with planned 400,000 BTUh (2023) and 20 kW / 1 million BTUh (2024) models, the boiler supports multiple fuels (natural gas, LPG, hydrogen, RNG) and includes black-start backup power capability, positioning it as both a decarbonization and resilience solution for buildings facing carbon-emissions regulations such as NYC Local Law 97.

The company's commercial model is built around one-time hardware sales priced at approximately $20,000-$24,000 installed for the 6 kW light-commercial unit and $8,000-$9,000 for the 5 kW residential unit, supplemented by a pre-order program and a future grid-services revenue stream envisioned through a 'Virtual Regulated Network' aggregating boilers into a virtual power plant. Manufacturing and distribution are handled through a strategic OEM partnership with Burnham Holdings, one of the largest U.S. boiler manufacturers, which launched serial production of the SW300-6 model following Intertek ETL certification in December 2022. Go-to-market combines direct sales (led by Director of Sales Stu Fox targeting co-op boards, property owners, and commercial developers), channel partners including HVAC contractors, plumbers, engineers (with Syska Hennessy Group endorsement), utility incentive specialists, and energy consultants, and an active trade-show presence across Northeast markets. Named deployments as of 2023 include the Fuller Brush building in Hartford, Wesleyan University, and the Cambridge House co-op in the Bronx.

Founded in 2015 by mechanical engineer Michael Cocuzza and now led by CEO Dan Nadav (with Cocuzza as President and CTO), Enviro Power operates as a venture-backed private company headquartered in South Windsor, CT. The company holds patents on its mCHP architecture and dual-condensing combustion chamber, is part of the NYSERDA / Clean Energy Business Incubator Program ecosystem, and is supported by partnerships with Connecticut Innovations, UConn's Eversource Energy Center, and Windings Inc. for generator co-development. Revenue has not been publicly disclosed and the company remains in pre-commercial to early-commercialization stage, with CEO projections of 100-200 units sold in 2023 and 500+ in 2024.

Revenue model

1. SmartWatt Boiler hardware sales: Primary revenue stream: one-time sale of SmartWatt Boiler units (5 kW residential and 6 kW light-commercial models) to building owners, property managers, and commercial customers. Pricing starts at approximately $20,000–$24,000 installed for the 6 kW unit. Pre-orders are accepted via the company website.
2. Pre-order / early demand pipeline: Active pre-order program for upcoming deployments; customers can request free energy analyses and reserve units ahead of installation, capturing qualified leads and committed demand before delivery.
3. Future grid services revenue (Virtual Regulated Network): Future revenue stream envisioned via aggregating SmartWatt Boilers into a 'virtual power plant' that utilities or grid operators could dispatch to provide peak-load and balancing services, with participating propane/building owners compensated for electricity generated on demand.

Core offering

Enviro Power designs, patents, and sells the SmartWatt Boiler, a drop-in replacement boiler with an integrated micro combined heat and power (mCHP) generator. The system uses a closed-loop radial micro-steam turbine inside a patented dual-condensing combustion chamber to convert heat normally lost in conventional boilers into up to 6 kW of on-site electricity while delivering approximately 98% HHV heating efficiency and integrated backup power. It is offered as a 5 kW/150,000 BTUh residential unit and a 6 kW/300,000 BTUh light-commercial unit (SW300-6), manufactured in the U.S. through Burnham Holdings.

Product overview

Enviro Power offers a single core product family built around the SmartWatt Boiler — a drop-in replacement boiler that integrates an internal micro combined heat and power (mCHP) generator. The SmartWatt Boiler uses a closed-loop, radial micro-steam turbine housed in a patented dual-condensing combustion chamber to convert heat normally lost in conventional boilers into usable electricity, delivering up to 6 kW of free onsite power alongside nearly 98 percent (HHV) heating efficiency and continuous backup power. The product is offered as the SmartWatt Boiler (Residential) — a 5 kW / 150,000 BTUh unit for single-family homes — and the SmartWatt Boiler SW300-6 (Light Commercial) — a 6 kW / 300,000 BTUh unit for multifamily and commercial buildings. Planned extensions include larger 400,000 BTUh and 20 kW / 1 million BTUh models. Manufactured in the U.S. in partnership with Burnham Holdings and developed with Windings Inc., the SmartWatt Boiler is ETL-certified under UL standards.

Others

• Burnham Holdings: Enviro Power's OEM manufacturing and distribution partner and Series A co-investor. While not a direct competitor, Burnham's portfolio of legacy boiler brands (e.g., Burnham, Weil-McLain, U.S. Boiler Company) sells conventional condensing boilers that compete for the same replacement projects as SmartWatt.

Broad incumbents

• Bloom Energy: Provides fuel-cell-based distributed power and increasingly building-scale cogeneration. Competes for the decarbonization budgets of large commercial real estate and institutional customers alongside mCHP solutions like SmartWatt.
• Bosch Thermotechnology: A large incumbent HVAC manufacturer with condensing boilers and broader thermal offerings. Competes with Enviro Power's SmartWatt in high-efficiency boilers and is a potential strategic threat given its scale and channel reach.
• Viessmann: European heating incumbent with high-efficiency condensing boilers and growing hydrogen-ready product lines, competing for the same boiler-replacement and decarbonization budget as SmartWatt.
• Generac: Dominant North American distributed-generation and backup-power provider. Competes with SmartWatt's black-start backup power feature and increasingly with combined heat-and-power / energy resilience solutions.

Direct peers

• Rinnai: Sells high-efficiency tankless water heaters and boilers in North America, competing with SmartWatt for replacement dollars in residential and light-commercial heating applications.
• Navien: Manufacturer of high-efficiency condensing boilers and combi units for residential and light-commercial U.S. markets, directly competing on efficiency and total installed cost against SmartWatt.
• Marathon Engine Systems (ecopower): Sells engine-based micro-CHP units for residential and light-commercial buildings, directly competing with Enviro Power's SmartWatt Boiler in the same mCHP / building cogeneration category.
• Yanmar (micro-CHP): Offers gas-engine micro-CHP systems (e.g., CP5WN) targeted at residential and small commercial buildings in Europe and North America, the closest engine-based mCHP alternative to Enviro Power's steam-turbine approach.

Emerging players

• Capstone Green Energy: Sells microturbine-based combined heat and power and CHP systems for commercial and industrial customers, addressing the same on-site heat-plus-power use case as Enviro Power's SmartWatt at higher capacities.
